Description

  The present invention relates to a building wall surface cooling system and a building cooling system using a water hammer effect.

  In recent years, as the area centering on Tokyo has become centralized, buildings have become denser and the road surface is covered with asphalt, so it is not possible to secure a place for rainwater to fall. In addition, the incidence of abnormal weather caused by the heat island phenomenon, “local heavy rain”, is increasing every year. Currently, sewerage end-treatment facilities tend to exceed the permissible amount of sewage treatment due to such a situation, and are forced to stop functioning during repeated heavy rains. Therefore, local governments have established “rainwater runoff control” by regulations, and are obliged to control rainwater proportional to the site area mainly in newly developed areas. There are two ways to suppress it.

  The first suppression method is “providing rainwater infiltration facilities around the site”. The second suppression method is “providing a rainwater storage tank”. With these two control methods, rainwater generated from the site will be temporarily suppressed within the site, and the amount of sewage treated at the sewer end treatment facility will be controlled (http://www.gesui.metro.tokyo.jp) /kanko/kankou/gyoumu/usuishintou.pdf).

  However, in order to promote these ordinances, a considerable amount of equipment must be provided, which in turn imposes a burden on the owner. In addition, since it is not applied in principle to buildings that have already been built, the current situation is that progress has not been made slowly.

  By the way, there are countless buildings (buildings, condominiums, etc.) that have FRP (Fiber Reinforced Plastics) tanks on their rooftops, both in Japan and overseas. FRP is light and strong, and has high chemical resistance, corrosion resistance, and heat insulation, so it has been used to store drinking water and water for daily use by residents of buildings.

  In recent years, with the renovation of equipment, the number of cases where this tank itself is not required is increasing. The characteristics of the FRP described above confirm that disposal is difficult. In fact, the removal of the tank is expensive, so it is often left untouched. Even when the tank is removed, the location and method of disposal are limited because the tank itself is quite large and sturdy.

  FIG. 1 is a side view showing a typical building using a conventional direct pressure water supply system. The building 100 to which the direct pressure water supply method is applied uses a pressure pump 103, a water receiving tank 104, a pumping pipe 105, and an elevated water tank 106.

  In this water supply system, a water main pipe 101 buried in the ground is piped to a water receiving tank 104 through a public water meter 102. The water receiving tank 104 is formed of FRP, and is used for an apartment house where water cannot be sufficiently supplied only by the water pressure of the water main pipe 101. A pumping pipe 105 is connected to the water receiving tank 104 via a pressure pump 103. The pumping pipe 105 is made of a material that is not easily rusted and has a good appearance (for example, a steel pipe or a vinyl pipe), and is connected to an elevated water tank 106 installed on the roof of the building 100. The pressure pump 103 pumps the water stored in the water receiving tank 104 to the elevated water tank 106. The pumped water is stored in the elevated water tank 106 and supplied to each household on each floor in the building by natural flow.

  FIG. 2 is a side view showing a building that uses the increased pressure water supply system while leaving the direct pressure water supply system.

  The difference from the direct pressure water supply method shown in FIG. 1 is that a direct connection pressurizing pump unit (pressurizing pump 208) is installed. By the pressurizing pump 208, the water sent from the water main pipe 101 can be directly supplied to each floor of the middle-high-rise building. In the pressure increase water supply method, water is directly supplied from the water main 101 to each household in each floor in the building, which is hygienic and does not require the water receiving tank 104 or the elevated water tank 106.

  Today, when the pressurized water supply method is widespread, the treatment of the water receiving tank 104 and the elevated water tank 106 that are no longer necessary has become a social problem. This is because the removal cost is enormous and it is difficult to dispose of the removed strong tank. Moreover, when it is left as it is without being removed, not only the appearance of the building is impaired, but also the earthquake resistance strength of the building is impaired. Also, a sturdy tank that is left unattended causes contamination and requires maintenance.

  By the way, although “summer is hot in summer!”, The summer heat and torrential rain in urban areas in recent years are unusual. In particular, the average annual temperature in Tokyo has risen by 3.0 ° C over the past 100 years, which is larger than the average rising temperature of 2.4 ° C in other large cities and the average rising temperature of 1 ° C in small and medium-sized cities. It is rising. The cause of this rise in temperature is not only global warming but also the heat island phenomenon, and the tendency of urban warming is becoming more prominent.

Global warming
From around the latter half of the 18th century, industrial activities became active and began to consume large amounts of coal and oil. The amount of carbon dioxide in the atmosphere increased by about 30% compared to 200 years ago, and a large amount of greenhouse gases such as carbon dioxide, methane, and chlorofluorocarbons were discharged, and the concentration in the atmosphere increased and heat absorption increased. As a result, the temperature is starting to rise.

  If human activities continue to change in the same way, it is predicted that at the end of the 21st century, the concentration of carbon dioxide will more than double the current level, and the average global temperature will rise by 1.4 to 5.8 ° C. Even in 1998, when it was said that it was unprecedented, the average temperature was only about 1 ° C higher than usual. In this way, even a slight rise in temperature has an effect that can be a life and death problem.

  As global warming progresses, various problems such as food problems, natural disasters, and economic problems will occur, as well as the problem of increasing the human sensory temperature.

Heat Island Phenomenon The heat island phenomenon is thought to be due not only to exhaust gas discharged from factories and cars, but also from office buildings and houses. That is, when the air conditioner is fully operated on a summer day and the room temperature is lowered, the outdoor unit blows hot air and the temperature rises. If this is not cut off somewhere, the root of the heat island phenomenon will not disappear forever.

  In addition, asphalt is heated to the deepest by daytime solar heat, and the heat accumulated at night is released. Trees exhale a large amount of water into the air, and when the area of green space decreases, the amount of water evaporation from plants and the ground surface decreases, and the latent heat of evaporation decreases. Furthermore, the use of various types of energy has increased due to the concentration of the population, and the amount of exhaust heat has increased. Furthermore, since multiple reflection is performed on the wall surface of a high-rise building or the like, urban structures are easily heated.

A variety of efforts To deal with these problems, various efforts are being made throughout the country and around the world in response to severe heat island phenomena and global warming. For example, by removing the tie and not wearing a jacket, the temperature setting of the air conditioner is fixed at 28 ° C, the sensible temperature is controlled, the room temperature is kept constant, and the rise in outside air and energy consumption fall. There is an effort to make.

  Therefore, the present invention makes effective use of the tanks (including new construction) currently installed on the rooftops of many buildings (buildings and condominiums), constructs a circulation cycle with water, and heat island phenomenon / global warming The purpose is to stop.

  The wall surface cooling system according to the first embodiment of the present invention may further include a discharge means for discharging the liquid in the second storage means. Thereby, the inside of a 2nd storage means can be emptied as needed.

  A second embodiment of the present invention is a system for cooling a building having a discharge port for discharging liquid downward from the upper part, and is a first storage means that is placed higher than the upper part of the building and stores liquid. The second storage means that is placed below the first storage means, forms a bottom surface in a plane including the discharge port, and stores the liquid on the bottom surface, and the liquid level that is installed at the discharge port and raises the liquid discharge position. Ascending means, outflow means for flowing out the liquid stored in the first storage means toward the second storage means, first flow rate control means for controlling the flow rate of the liquid flowing out by the outflow means, and first flow rate control System control means for controlling the means, and the system control means controls the first flow rate control means to form a liquid film on the bottom surface of the second storage means.

  The first storage means has a function of storing liquid (rain water, tap water, well water, etc.). For example, an existing elevated water tank and FRP tank can be used as the first storage means.

  Similarly, the second storage means has a function of storing a liquid. Unlike the 2nd storage means of 1st Embodiment, it is desirable that it is a container which has a flat bottom face.

  The liquid level raising means has a function of raising the discharge position from the bottom surface of the second storage means.

  According to the present invention, a building and its wall surface can be cooled efficiently. Therefore, the amount of accumulated heat released at night, which is considered to be the cause of the heat island phenomenon, can be reduced, and heating of the building itself can be suppressed. Moreover, since a building and a wall surface are cooled using the water hammer effect, a building and a wall surface can be cooled with a little energy.

Here, the water hammer effect is a phenomenon in which the heat of vaporization taken away by watering lowers the temperature. According to the calculation by the independent civil engineering research institute, for example, if one liter of water per square meter is sprayed in a place where water can be sprayed in Tokyo, the temperature will drop by 2 ° C overall. By spreading the present invention, it is possible to make a great contribution to the reduction of greenhouse gases (such as CO ₂ ) that cause global warming.

  Furthermore, when an elevated water tank and a water receiving tank are already installed in the building, these facilities can be used effectively without causing the cost of removing them and the problem of waste disposal.

  Therefore, since the present invention can construct a circulation cycle with water, it becomes a model to stop the heat island phenomenon and global warming.

[First embodiment: Wall watering system]

  FIG. 3 is a side view showing an outline of the wall surface watering system according to the first embodiment of the present invention, and FIG. 4 is a diagram showing an example of a first rainwater storage tank that can be used for the wall surface watering system. 5 is a figure which shows one Example of the 2nd rainwater storage tank which can be used for the wall surface watering system.

The wall surface watering system according to the first embodiment of the present invention is as follows.
A first rainwater storage tank 410 (first storage means) that is placed on an upper part of a building 309 having a wall surface and stores rainwater (liquid) and a position lower than the first rainwater storage tank 410 (first storage means). The second rainwater storage tank 507 (second storage means) for storing the rainwater (liquid) and the rainwater (liquid) stored in the second rainwater storage tank 507 (second storage means) are stored in the first rainwater. A wall surface cooling system including a rainwater pump 518 and a rainwater pumping pipe 401 (liquid moving means) to be moved to a tank 410 (first storage means),
An outflow main pipe 418 for discharging rainwater (liquid) stored in the first rainwater storage tank 410 (first storage means) to the upper peripheral edge of the building, a discharge header 424, and a shower head 425 (discharge means);
A gate valve 419 and an electromagnetic valve 420 (flow rate control means) for controlling the flow rate of rainwater (liquid) discharged by the outflow main pipe 418, the water discharge header 424 and the shower head 425 (discharge means);
A control panel 801 (system control means) for controlling the rainwater pump 518 (part of the liquid moving means) and the electromagnetic valve 420 (part of the flow rate control means);
Further comprising
The control panel 801 (system control means) controls the rainwater pump 518 (a part of the liquid movement means) and / or the electromagnetic valve 420 (a part of the flow rate control means), so that rainwater (liquid) is applied to the wall surface of the building. A film is formed.

Around the first rainwater storage tank (elevated water tank): 400

The rainwater pumping pipe 401 is a pipe for allowing rainwater sent from the second rainwater storage tank 507 by the rainwater pump 518 to flow into the first rainwater storage tank 410 and is piped along the wall surface of the building. . The material of the rainwater pumping pipe 401 may be a steel pipe or a vinyl pipe as long as it does not rust and has a good appearance. A gate valve 403 is installed in the rainwater pumping pipe 401 near the roof of the building. The gate valve 403 is normally in an “open” state, and is closed at the time of cleaning / maintenance of the first rainwater storage tank 410 and at the time of removal / relocation of the first rainwater storage tank 410 in the future.

  A large inflow pipe 404 with a gate valve and a ball tap inflow pipe 405 with a gate valve are connected to the downstream side of the gate valve 403. The inflow into the first rainwater storage tank 410 is performed by the large inflow pipe 404 and the ball tap inflow pipe 405. Generally, the diameter of the large inflow pipe 404 is about φ40 to φ100. This caliber can be calculated based on the flow rate that the first rainwater storage tank 410 can be filled within one hour. The gate valve of the large inflow pipe 404 is normally “open” for emergency stop.

  The ball tap inflow pipe 405 not only has a function of flowing into the first rainwater storage tank 410 but also has a function of stopping the inflow when the ball portion of the ball tap 408 is horizontal when the first rainwater storage tank 410 is full. have. If the ball tap inflow pipe 405 has a large diameter, a water hammer (water hammer) phenomenon occurs when the ball tap is stopped, so that a small diameter ball tap inflow pipe is required. Therefore, the diameter of the ball tap inflow pipe 405 is appropriately φ20. The gate valve of the ball tap inflow pipe 405 is normally in an “open” state, and is closed during maintenance.

  An air vent valve 407 and an air vent valve maintenance gate valve 406 are installed further downstream of the ball tap inflow pipe 405. The air vent valve maintenance gate valve 406 is normally open, and is mainly “closed” when the air vent valve 407 is replaced. The air vent valve 407 prevents an explosion phenomenon caused by the air accumulated in the rainwater pumping pipe 401.

  The first rainwater storage tank 410 can be configured by diverting from an existing elevated water tank to a rainwater storage tank. The elevated water tank originally existed for the purpose of storing clean water, but it is not necessary in the process of changing the water supply system to the pressure booster pump. When it is removed, it costs enormous removal and dismantling, so it is often left unattended. In addition, because the material is FRP (FRP: Abbreviation for Fiber Reinforced Plastics), it is removed and disposed, but the disposal method is entrusted to an industrial waste disposal company and landfilled. In addition, there is a method of reuse in other buildings, but in Japan there is a tendency to prefer new products for drinking, and there is no case of cleaning and reuse. Therefore, in the present invention, rainwater can be stored in this elevated water tank that cannot be disposed of and can be revived as another function, which is significant for recycling and environmental preservation.

  When the existing elevated water tank is reused as the first rainwater storage tank 410, a “rainwater storage tank” seal 409 is attached to the first rainwater storage tank 410. In this case, since the first rainwater storage tank 410 was originally intended to temporarily store clean water (drinkable), it is intended to call attention to those who do not know the circumstances of switching to rainwater (not drinkable).

  An overflow pipe 411 is connected to the upper part of the first rainwater storage tank 410. The overflow pipe 411 can be temporarily discharged by the overflow pipe 411 when the inflow cannot be stopped by the ball tap 408 due to a failure of the wall surface cooling system according to the present invention. The drained rainwater flows out to the top of the roof and flows to the rooftop drain as it is. Note that the overflow pipe 411 does not have a gate valve and is open to the first rainwater storage tank 410, thus allowing insects and the like to enter. Therefore, a mesh-like insect net 427 is attached to the discharge port, and the stable water quality of the elevated water tank is maintained.

  An outside air thermometer 412 is installed above the first rainwater storage tank 410. The measurement result of the outside air thermometer 412 is transmitted to the control panel 801 (see FIG. 8) via the wiring 423. The control panel 801 can set the operation of the wall surface cooling system to stop or resume depending on the outside air temperature.

  In addition, an electrode rod 413 is installed in the upper part of the first rainwater storage tank 410 as a full water detection means so as to protrude in the vertical direction. The electrode bar 413 identifies whether or not the inside of the first rainwater storage tank 410 is in a full state depending on whether or not the lowermost part of the bar has landed. The identification result by the electrode rod 413 is transmitted to the control panel 801 through the wiring 423. The control panel 801 stops the rainwater pump 518 when the tip of the electrode rod 413 has landed in the first rainwater storage tank 410, and prevents further inflow into the first rainwater storage tank 410. .

  In addition, a water temperature gauge 413 is installed inside the first rainwater storage tank 410 as a liquid temperature detecting means. The water temperature gauge 413 measures the water temperature in the first rainwater storage tank 410. The measurement result of the water temperature gauge 413 is transmitted to the control panel 801 through the wiring 423. The control panel 801 temporarily stops the operation of the wall surface cooling system when the water temperature is abnormally high, or when the water temperature is close to 0 degrees and there is a risk of freezing. Usually, the operating range is 26 ° C to 40 ° C in summer and 5 ° C to 15 ° C in winter.

  Further, an electrode bar 415 is disposed in the first rainwater storage tank 410 as a drought detection means so as to protrude in the vertical direction. The electrode rod 415 identifies whether or not the inside of the first rainwater storage tank 410 is in a drought state based on whether or not the lowermost portion of the rod is landing. The identification result by the electrode rod 415 is transmitted to the control panel 801 through the wiring 423. When the lowermost part of the electrode rod 415 has not landed in the first rainwater storage tank 410, the control panel 801 starts the rainwater pump 518 and keeps the water until the first rainwater storage tank 410 is full. Replenish.

  A cleaning drain pipe 417 is connected to the lowermost part of the first rainwater storage tank 410, and a drain valve 416 is installed in the drain pipe 417. The drain valve 416 is opened when there is a risk of regular tank cleaning or freezing due to abnormal cold waves, and the rainwater in the first rainwater storage tank 410 is discharged. Therefore, the drain valve 416 is normally set to the “closed” state. By using the cleaning drain pipe 417, rainwater in the first rainwater storage tank 410 is discharged when there is a risk of regular tank cleaning or freezing due to abnormal cold waves.

  Another L-shaped outflow main pipe 418 is connected to the side of the cleaning drain pipe 417. Two outflow pipes 603 and 710 are connected to the horizontal portion of the outflow main pipe 418. The outflow main pipe 418 and the two outflow pipes 603 and 710 are pipes for draining rainwater necessary for “wall watering”, “rooftop water basin” and “outdoor unit sprinkling” which are wall surface cooling systems according to the present invention. is there.

  In the case of a building where an elevated water tank was installed, the spill main 418 was directly connected to the water supply of the building. However, in the process of changing the water supply system to the pressure booster pump, the outflow main pipe 418 has become unnecessary. If this is processed into a 3-hole header, the existing outflow main can be reused. The diameter of the outflow main pipe 418 depends on the required amount of water, but approximately φ30 to φ75 is appropriate.

  A gate bubble 419 is installed in the outflow main pipe 418. The gate valve 419 is “closed” during maintenance of the “wall watering system”, but is normally “open”.

  Further, a wall watering electromagnetic valve 420 is installed on the downstream side of the gate valve 419 of the outflow main pipe 418.

  The electromagnetic valve 420 is electrically connected to the control panel 801 via the wiring 423 and controlled by the control panel 801.

  The wall watering electromagnetic valve 420 is automatically opened and closed by an electrical signal sent from the control panel 801. For example, if “start time 8:00”, “every water discharge pitch every hour”, and “water discharge time 5 minutes” are set on the control panel 801, the valve automatically “opens” in accordance with the setting conditions. Except for “Closed”.

  A water discharge header 424 is attached further downstream of the wall watering electromagnetic valve 420. The water discharge header 424 is a perforated pipe for mounting the wall surface water shower head 425. According to Pascal's principle, the water pressure is applied equally to any hole in theory. The material of the water discharge header 424 may be a steel pipe or a vinyl pipe as long as it does not rust and has a good appearance. An infinite number of holes with a diameter of about 0.5 mm are opened in the water discharge portion of the shower head 425 for wall surface water so that water can be discharged from there to the wall surface. The pitch of the holes depends on the water pressure from the first rainwater storage tank 410 and the environment of the building, but is usually installed at intervals of about 200 mm to 300 mm.

  Some buildings have balconies and bay windows protruding, and if the shower is discharged, that surface will flow away. In order to cover the surface, a spray gun 426 for water spraying on the wall surface is appropriately installed at a necessary place, and is configured to be sprayed in a mist form.

Around the second rainwater storage tank (water tank): 500

The building 309 is usually provided with a drain pipe 501 as a rain gutter. The drain pipe 501 usually falls from the four corners of the building, and is provided with rainwater drainage on the rooftop, each balcony, stairs and the like. This drain pipe 501 is connected to one at the height of the ceiling of the second rainwater storage tank 507, and rainwater can be secured by pouring into the second rainwater storage tank 507 with a constant gradient.

  A dust removal net 502 made of SUS is installed at the tip of the drain pipe 501. The dust removal net 502 removes relatively large dust such as fallen leaves from rainwater flowing into the second rainwater storage tank 507 from the drain pipe 501.

  The second rainwater storage tank 507 originally existed for the purpose of storing clean water. However, like the elevated tank, it is not necessary in the process of changing the water supply system to the pressure booster pump. When it is removed, it costs enormous removal and dismantling, so it is often left unattended. Moreover, since the material is FRP, it is removed and disposed, but the disposal method is entrusted to an industrial waste disposal company and landfilled. In addition, there is a method of reuse in other buildings, but in Japan there is a tendency to prefer new products for drinking, and there is no case of cleaning and reuse. In the present invention, this water receiving tank that cannot be disposed of can be effectively used as the second rainwater storage tank. In this case, it is desirable to attach a “rainwater storage tank” seal 508 to the surface of the second rainwater storage tank 507. Originally, since the second rainwater storage tank 507 temporarily stores clean water (drinkable), it is intended to call attention to those who do not know the circumstances of switching to rainwater (not drinkable).

  In addition, an electrode bar 503 is installed in the upper part of the second rainwater storage tank 507 as a full water detection means so as to protrude in the vertical direction. The electrode rod 503 identifies whether or not the inside of the second rainwater storage tank 507 is full based on whether or not the lowermost portion of the rod is landing. The identification result by the electrode rod 503 is transmitted to the control panel 801 through the wiring 423. When the tip of the electrode rod 503 has landed in the second rainwater storage tank 507, the control panel 801 automatically stops the drought water supply and stops the second rainwater storage tank 507 beyond that. To prevent inflow.

  Furthermore, an electrode rod 504 is disposed in the second rainwater storage tank 507 as a drought detection means so as to protrude in the vertical direction. The electrode rod 504 identifies whether or not the inside of the second rainwater storage tank 507 is in a drought state based on whether or not the lowermost portion of the rod is landing. The identification result by the electrode rod 504 is transmitted to the control panel 801 through the wiring 423. When the lowermost part of the electrode rod 504 has not landed in the second rainwater storage tank 507, the control panel 801 automatically continues to supply drought-use replenishing water until the water is full.

  Two rainwater pumps 518 are installed below the second rainwater storage tank 507, and are connected to the rainwater pumping pipe 401 via the rainwater pump 518. As described above, the rainwater pumping pipe 401 is a pipe for allowing the rainwater sent from the rainwater pump 518 to flow into the first rainwater storage tank 408.

  In many cases, two pumps are installed in the water receiving tank. This is because even if one unit breaks down, the other unit can be operated, and any water outage is eliminated. When a pumping pump is installed in the water receiving tank, the pumping pump can be used as the rainwater pump 518. 90% or more of the pumping pumps that are normally used in existing water receiving tanks are “multistage centrifugal pumps”. The “multistage centrifugal pump” can obtain pressure by centrifugal force generated by the rotation of the impeller.

  In recent years, with the spread of the “pressure booster pump”, this pump is often left as it is together with the water receiving tank. In addition, disposal of two pressure pumps as industrial waste is quite expensive. There is also a method of reuse in other buildings, but in Japan there is a tendency to prefer new products for drinking, and there is almost no case of reuse after cleaning. When a pumping pump is installed in an existing water receiving tank, the pumping pump having this excellent function can be diverted as a rainwater pump 518 and revived by raising rainwater instead of drinking water.

  The second rainwater storage tank 507 is provided with a drought refill faucet 509 and an electromagnetic valve 510 connected to a public water main as replenishment means. The drought refill faucet 509 can be stably operated by temporarily injecting public water managed and operated by the local government when the stored rainwater is depleted, such as when the weather continues. Needless to say, well water can be substituted for public water supply. The solenoid valve 510 is automatically opened and closed by an electrical signal sent from the control panel 801. This electromagnetic valve 510 is controlled by a control panel 801. Specifically, the electromagnetic valve 510 is “open” to automatically inject water when the lower end portion of the electrode rod 504 is not landed, and automatically when the lower end portion of the electrode rod 503 is landed. “Closed” to stop. Thereby, the 2nd rainwater storage tank 507 is always in a full state, and can be used anytime.

  A gate valve 511 is installed between the electromagnetic valve 510 and the public water pipe. The gate valve 511 is used during maintenance of the second rainwater storage tank 507 and the electromagnetic valve 510. For example, the gate valve 511 is normally in an “open” state, but is mainly “closed” when the electromagnetic valve 510 is replaced.

  An overflow pipe 512 is connected to the upper part of the second rainwater storage tank 507. The overflow pipe 512 temporarily discharges the overflow pipe 512 when the inflow cannot be stopped by a ball tap or the like due to a failure of the wall surface cooling system according to the present invention. The discharged rainwater flows out into the gutter 519 and flows into the sewer main 520. Note that the overflow pipe 512 does not have a gate valve and is open to the second rainwater storage tank 507, so that an insect or the like can enter. Therefore, a mesh-like insect net 517 is attached to the discharge port, and the stable water quality of the second rainwater storage tank 507 is maintained.

  A faucet tapping 513 is installed at the uppermost part (ceiling part) of the second rainwater storage tank 507. When the drought replenishing faucet 509 connected to the water main pipe 101 is directly connected to the second rainwater storage tank 507, there is a risk that a vacuum phenomenon occurs and rainwater flows into the water main pipe 101. Therefore, it is necessary to secure a water discharge space (a constant space so that the faucet does not land on the rainwater surface). When the tapping 513 is installed, a water discharge space is secured. In this case, there is a possibility that dust and fallen leaves may enter through the gap of the water discharge space, so it is desirable to install a “dust removal net” here as well.

  As described above, rainwater that has passed through the “garbage removal net” is stored in the second rainwater storage tank 507, but some dust and dust remain. Such dust and dirt accumulate at the bottom of the water tank due to gravity over time. For this reason, a SUS Kasaage device 514 (see FIG. 9) is installed as a foreign matter removing means. By installing the Casa Age device 514, good quality rain water can be sent to the rain water pump 518 from a position above the bottom surface by a certain distance (for example, 10 cm). The dust and dirt accumulated at the bottom of the second rainwater storage tank 507 are cleaned and disposed of during regular maintenance.

  Below the second rainwater storage tank 507, a drain valve 515 is installed as a discharge means via a drain pipe 516. The drain valve 515 discharges rainwater in the second rainwater storage tank 507 when there is a risk of periodic tank cleaning or freezing due to abnormal cold waves. Therefore, the drain valve 515 is normally in a “closed” state.

  As described above, in order to receive extra rainwater through the overflow pipe 512 when the inflow cannot be stopped by a ball tap or the like due to a failure or the like, the lattice fence 519 is installed. Rainwater that flows into the gutter 519 flows into the sewer main 520.

  In recent years, the amount of sewage treatment tends to exceed the permissible amount at sewer end treatment facilities. The era when the rainwater that has been poured can just be drained into the sewer main 520 is over. In the coming era, we must consider processing (penetration and storage) on our own premises. It is a system that meets the requirements of such times.

  The full water detection electrode rod 503, the drought detection electrode rod 504, and the electromagnetic valve 510 are electrically connected to the control panel 801 via the wiring 423 and controlled by the control panel 801.

Second embodiment: roof basin system

   FIG. 6 is a side view showing an outline of a roof basin system according to the second embodiment of the present invention, and FIG. 7 is a side view showing an outline of an outdoor unit watering system according to the second embodiment of the present invention.

The rooftop water basin system according to the second embodiment of the present invention is
A system for cooling a building 309 having a drainage port (discharge port) for discharging rainwater (liquid) downward from the upper part,
A first rainwater storage tank 410 (first storage means) that is placed higher than the top of the building and stores rainwater (liquid);
A roof basin 608 (second tank) which is placed below the first rainwater storage tank 410 (first storage means), forms a bottom surface with a plane including a drain port (discharge port), and stores rainwater (liquid) on the bottom surface. Storage means),
A raising device 602 (liquid level raising means) installed at the drainage port (discharge port) to raise the discharge position of rainwater (liquid);
An outflow pipe 603 (outflow means) for flowing out rainwater (liquid) stored in the first rainwater storage tank 410 (first storage means) toward the roof basin 608 (second storage means);
A gate valve 604 for controlling the flow rate of rainwater (liquid) flowing out by the outflow pipe 603 (outflow unit) and an electromagnetic valve 605 for the basin (first flow rate control unit);
A control panel 801 (system control means) for controlling the electromagnetic valve 605 for basin (a part of the first flow rate control means);
Further comprising
The control panel 801 (system control means) controls the basin solenoid valve 605 (part of the first flow rate control means) to form a rainwater (liquid) film on the bottom surface of the rooftop water board 608 (second storage means). It is characterized by forming.

Rooftop basin

Hereinafter, with reference to FIG. 6, an example of the roof basin that can be used in the second embodiment of the present invention will be described.

  The building is provided with a first rainwater storage tank 410 at the top and a drain pipe 601. The drain pipe 601 usually falls from the four corners of the building, and is provided with rainwater drains on the rooftop, each balcony, stairs and the like. FIG. 6 shows an example of piping arranged to remove rainwater on the roof. At the drain outlet, a Casa Age apparatus 602 is installed, and the drainage position is high. The Casa Age device 602 can be installed at a drain outlet on the roof to raise the drainage position by several centimeters, and can fill the amount of the rise. The water stored on the roof forms a “basin”. In the absence of the lizard device 602, rainwater that has poured onto the rooftop naturally flows down with a gentle gradient and is always in a dry state, as is conventional. The present invention makes it difficult for the slab (floor concrete), which continues to be in such a dry state, to be stored by direct sunlight in the summer, using a ladle. This roof basin system has the effect of removing vaporization heat and cooling the building as well as the watering effect. Since the water used uses the rainwater stored, it leads to rainwater outflow control at the same time.

  A roof basin effluent pipe 603 is branched downward from a part of the effluent main pipe 418 connected to the lower part of the first rainwater storage tank 410. The outflow pipe 603 for the rooftop water basin is a pipe for allowing rainwater necessary for the “rooftop basin” to flow out. Although it was directly connected to the water supply of the building from this pipe, it was not necessary in the process of changing the water supply system to the booster pump.

  In the outflow pipe 603 for rooftop water basin, a gate valve 604 and a solenoid valve 605 for rooftop water basin are installed as flow control means. The gate valve 604 is normally in the “open” state, but is “closed” during maintenance of the “rooftop basin” system. The electromagnetic valve 605 for the roof water basin is automatically opened and closed by an electric signal sent from the control panel 801. For example, if “water filling time 8:00” is set on the control panel 801, the valve is automatically “open” at that time.

  The roof basin 608 formed on the roof is provided with an electrode box 607 containing an electrode bar as a liquid level detecting means. Whether or not water is stored is identified based on whether or not an electrode rod (not shown) built in the electrode box 607 has landed. The identification result is transmitted to the control panel 801 via the wiring 423. When the electrode (not shown) has not landed, the roof basin solenoid valve 605 continues to operate until the roof basin 608 reaches a certain level. In case of rain, the water level will rise due to the rain water and it will land, so it will not operate on that day.

As described above, the roof basin 608 is formed by the Casa Age device 602. For example, the water level is 30 mm, and water can be stored so that the unit area per 1 m ² of the roof is 0.03 tons. This amount of water is a specific gravity that has almost no adverse effect on the building. Also, the amount of water becomes 3 liters. In the case of Tokyo, even if it is exposed to sunlight all day, the evaporation amount is about 500 deciliters, so it is not easy to cut the basin. Further, since the control panel 801 automatically replenishes when the water level falls, a stable cooling effect can always be obtained during the season.

  A drainage pipe connected to the drain outlet is connected with a solenoid valve 609 for draining the roof basin. The electromagnetic valve 609 for draining the roof basin is configured such that the valve is automatically opened and closed by an electric signal sent from the control panel 801. The roof water drain electromagnetic valve 609 is normally set (closed), but is controlled to be opened (open) when the time set in advance on the control panel 801 is reached. When the electromagnetic valve 609 for draining the roof basin is opened, the water in the roof basin 608 is drained. The drained water passes through the existing rainwater, enters the second rainwater storage tank 507 again, and is circulated (see FIG. 3).

  The roof basin solenoid valve 605, the electrode box 607, and the roof basin solenoid valve 609 are electrically connected to the control panel 801 via the wiring 423 and controlled by the control panel 801.

Outdoor unit watering

Hereinafter, with reference to FIG. 7, one Example of the outdoor unit watering system which can be used for 2nd Embodiment of this invention is demonstrated.

  An outdoor unit sprinkling outflow pipe 710 is branched from a horizontal portion of a crank-shaped outflow main pipe 418 connected to the lower portion of the first rainwater storage tank 410. The outflow pipe 710 is provided with a gate valve 707 and an electromagnetic valve 708 as flow control means. The gate valve 707 is set to “closed” during maintenance of the “outdoor unit watering system”, but is normally in the “open” state. The solenoid valve 708 is automatically opened and closed by an electric signal sent from the control panel 801. For example, if “10 minutes per water discharge pitch” and “5 minutes water discharge time” are set in the control panel 801, the valve of the electromagnetic valve 708 is automatically “open” at that time.

  On the downstream side of the electromagnetic valve 708 installed in the outflow pipe 710, an outflow branch pipe 706 equal to the number of outdoor unit installation places is connected. In FIG. 7, as an example, three outdoor units are displayed, but the number of outdoor units, installation locations, and installation directions vary depending on buildings. Since the outdoor unit watering system which concerns on one Embodiment of this invention sprays using piping, it is applicable to all buildings.

  For example, the outdoor unit water spout branch pipe 706 connected to the uppermost stream side of the outflow pipe 710 is used to sprinkle the outdoor unit 702 (the left side is shown) installed on the roof. The outdoor unit sprinkling outflow branch pipe 706 is a pipe through which rainwater necessary for the “outdoor unit sprinkling system” flows out. Although it was directly connected to the water supply of the building from the outflow branch pipe 706, it became unnecessary in the process of changing the water supply system to the pressure booster pump. As an example of the air conditioner outdoor unit 702, a general unit installed in a general building is shown in FIG. On the downstream side of the outflow branch pipe 706, a gate valve 705 and a shower head 704 for watering are attached. The gate valve 705 is “closed” during maintenance of the “outdoor unit sprinkling system”, but is normally “open”. The watering shower head 704 is installed on the downstream side of the gate valve 705 and has a function of watering the aluminum fins of the outdoor unit 702. Therefore, innumerable holes having a diameter of about 0.5 mm are formed in the watering portion of the watering shower head 704. Since the air conditioner dissipates heat by the fins of the outdoor unit, if water is sprayed on the fins, the cooling effect is increased by vaporization (water spray effect), and the cooling effect is drastically improved. Since the water sprayed on the fins evaporates in about 5 to 10 minutes, spraying at least every 10 minutes is effective.

  In the outflow pipe 710, a portion further downstream from the branch point of the outflow branch pipe 706 is piped along the building to another outdoor unit 702 (a front portion is shown). A gate valve 703 and a water spray shower head 701 are attached to the distal end of the outflow branch pipe 706. The gate valve 703 is “closed” during maintenance of the “outdoor unit watering system”, but is normally “open”. The watering shower head 701 is installed on the downstream side of the gate valve 703 and has a function of watering the aluminum fins of the outdoor unit 702.

  The roof basin solenoid valve 708 is connected to the control panel 801 via the wiring 423 and is controlled by the control panel 801.

  In the roof basin according to the above embodiment, the solenoid valve is installed in the outflow branch pipe 701. However, if the solenoid valve is installed in the outflow pipe piped to each outdoor unit branched from the outflow branch pipe 701, each outdoor unit is controlled. It can be controlled by the panel 801.

Casa Age Device (Round)

FIG. 9 shows an example of a lizard apparatus that can be used in the first and second embodiments of the present invention.

  Hereinafter, with reference to FIGS. 9A to 9C, an example of the cabbage apparatus 514 will be described as foreign matter removing means that can be used in the first embodiment of the present invention. As shown in FIG. 5, the Casa Age device 514 is used to remove foreign substances from rainwater stored in the second rainwater storage tank 507. The Casa Age device 514 includes, for example, an eye plate 901, a collar 902, a hook hook 903 for removal, a main body side surface portion 904, and an adjuster 905.

  The eye plate 901 can remove relatively large foreign matter so that fallen leaves and the like do not enter. The eye plate 901 can be mainly made of a metal plated, but it does not take much weight and can be made of plastic.

  The collar 902 is in close contact with the drain outlet, and the drainage position is raised by this thickness.

  Removal hook hooks 903 are provided at two locations. When the main body side surface portion 904 described later is squeezed into the drainage pipe and then removed, it may be lifted by passing a wire or the like through the hook hook hole. The removal hook hook 903 can be made of rubber.

  The main body side surface portion 904 is a portion to be inserted into the drain port. Since the diameter of the main body side surface portion 904 matches the inner diameter of the drainage pipe, the drainage pipe and the main body side surface portion 904 are in close contact with each other. When a lubricant (soap water or the like) is applied to the outer peripheral portion of the main body side surface portion 904, the main body side surface portion 904 can be easily placed in the drain pipe. When the main body side surface portion 904 is too long, a long portion may be cut. The main body side surface portion 904 can be made of rubber.

  If the adjuster 905 is inserted into the main body side surface portion 904, the so-called “rib” portion is simply thickened. Therefore, the amount of raising can be adjusted by using the adjuster 905. By using the adjuster 905 having a length different from, for example, 5 mm, 10 mm, and 50 mm, the raising amount can be changed to a desired length by itself or in combination.

Casa Age device (square type)

Hereinafter, with reference to FIGS. 9D to 9H, an example of the lizard apparatus 602 will be described as foreign matter removing means that can be used in an embodiment of the present invention. As shown in FIG. 6, the Casa Age device 602 is used to remove foreign substances from rainwater stored in a roof basin 608. The Casa Age device 608 includes, for example, an eye plate 906, a collar 907, a hook hook 908 for removal, a main body side surface 909, a square attachment 910, and an adjuster 911.

  The eye plate 906 can remove relatively large foreign matter so that fallen leaves and the like do not enter. The eye plate 906 can be mainly made of a metal plated, but it does not require much weight, so it can also be made of plastic.

  The collar 907 is in close contact with the periphery of the drain and is raised by the thickness of the adjuster 911 which will be described later.

  Detachment hook hooks 908 are provided at two locations. When removing the main body side surface portion 909, which will be described later, after swallowing it into the drain pipe, it may be lifted by passing a wire or the like through the hook hook hole. The removal hook hook 908 can be made of rubber.

  The main body side surface portion 909 is inserted into a square attachment 910 described later. Since the size of the outer periphery of the main body side surface portion 909 matches the size of the inner periphery of the square attachment 910, the main body side surface portion 909 is in close contact with the square attachment 910. When a lubricant (soap water or the like) is applied to the outer peripheral portion of the main body side surface portion 909, the main body side surface portion 909 can be easily put into the square attachment 910. If the main body side surface portion 909 is long, a long portion may be cut. The main body side surface portion 909 can be made of rubber.

  Square attachment 910: In the case of a square shape, the mouth is special because it is normally connected to a drain pipe (circular shape) below 10 cm. Therefore, the square attachment 910 is once attached, and the main body side surface portion 909 is inserted from above the square attachment 910. The square attachment 910 can be made of rubber.

  If the adjuster 911 is inserted into the main body side surface portion 909, the so-called “rib” portion is simply thickened. Therefore, the amount of raising can be adjusted by using the adjuster 911. By using an adjuster 911 having a length different from, for example, 5 mm, 10 mm, and 50 mm, the amount of raising can be changed to a desired length by itself or in combination.

  According to the first embodiment of the present invention, the rainwater stored in the water receiving tank or the tap water pumped up from the receiving water tank is temporarily stored in the existing elevated water tank, and then flowed to the wall of the building in a timely manner. Since the water flows through the building itself in the same way as the principle of “driving water”, the temperature inside the building is lowered. As a result, the amount of air-conditioner used can be reduced and electricity consumption can be reduced. Furthermore, it also leads to suppression of reflection and the like generated on the wall surface.

  According to the second embodiment of the present invention, a certain amount of water is poured from the FRP tank into the rooftop of the waterproofed building to create a pool on the rooftop. This stored water becomes a basin, avoiding direct sunlight, and also releases heat by vaporization heat to lower the temperature in the building.

  Moreover, an outdoor unit always exists outside the indoor air conditioner. Here, the hot air that blows out is also one of the factors that raise the temperature. Therefore, a water source is secured with the FRP tank, water is sprayed on the outdoor unit itself, and the temperature of the hot air discharged is lowered. Depending on the weather, such as sudden rain or sunshine, it is necessary to control the amount of water flowing from the FRP tank. In that case, it is desirable to incorporate a system that can automatically cope with this control panel.

  When forming a basin on the roof, it is effective to form a basin by applying a special lid to the current drainage outlet at the same time as waterproofing. However, in order to keep the thickness of the basin, it is desirable to install a cap-up type lid that stops the amount of water up to a certain amount and flows into the drain when it exceeds that amount, not just a lid.

  Although one embodiment of the present invention has been described above with reference to the accompanying drawings, the present invention is not limited to the embodiment shown in the drawings.

  For example, in the first embodiment of the present invention, the outflow pipe having the outflow function and the discharge function and the discharge pipe are separately used, but a single pipe having both functions can be used. What is important is the function of moving the liquid stored in the first storage means to the periphery of the building, and the number, shape, and material for realizing the function are not limited. For example, it is possible to provide both functions with a single tube.

  Moreover, although the solenoid valve is used as the flow rate control means of the first embodiment of the present invention, in addition to the solenoid valve, the one having a function of controlling the flow rate of the liquid discharged by the discharge means (valve, pipe, Can be used. The flow rate control includes flow rate increase / decrease control in addition to flow / no flow control.

  Furthermore, hydrophilicity can be improved by apply | coating a hydrotect (photocatalyst) to the wall surface of the building to which 1st Embodiment of this invention is applied. Hydrotect is commercially available from TOTO (http://www.toto.co.jp/products/hydro/index.htm).

  If the liquid used in the present invention is, for example, a liquid mixed with a disinfectant, the wall surface of the building can be easily disinfected. If hot water is used as the liquid, the building can be heated in cold weather.

  Similarly, although the 2nd rainwater storage tank is used as the 2nd storage means of 2nd Embodiment of this invention, you may apply | coat a hydrotect to the bottom face. By applying this, the hydrophilicity of the bottom surface can be increased.

In the present invention, the following can be easily realized by changing the liquid to be used.
1) Liquid → Disinfectant When it becomes necessary to disinfect the entire building, disinfection of the entire building can be easily performed by using a disinfecting liquid as the liquid in the wall surface cooling system of the present invention.
2) Liquid → Hot water The entire building can be easily heated. In this case, a boiler or a heating device is required separately.
3) Liquid → Deodorant If the place where the building is installed is an environment full of odors, flowing a liquid containing a deodorant on the wall of the building helps to improve the environment.
