Description

Closed cooling and heating and cool and hot water system using ground source}

The present invention relates to a closed type heating and cooling system using a geothermal source, and more particularly, to produce hot water and cold water at the same time as a geothermal source, by heating and cooling the produced cold and hot water to enable hot water even during cooling When using the geothermal source continuously in the heat pump, if the temperature of the geothermal source does not reach the proper range, the pumped groundwater is discharged to the outside and about 80% when the geothermal source temperature is above a certain temperature. Is discharged to the bottom of the underground excavation site, and the remaining 20% of the pumped groundwater is discharged to the upper underground area so that the discharged groundwater is absorbed evenly above and below the excavation site. Hermetic type using geothermal source that makes it easy to use geothermal source when efficiency is low The present invention relates to a heating, cooling and hot and cold water generation system.

In general, groundwater refers to water flowing below the surface of the earth, and the outer surface of the earth is covered with rocky crust, and water flows through the rock just below the ground where plants grow. Most groundwater is formed by the gathering of rain and snow melts that seep into the soil. When water reaches the rock, it flows through open gaps between the rocks. The speed of groundwater flow is not constant depending on the environment of the underground, so in some places it flows about 1.5m per day, but some groundwater flows very slowly at an average speed of about 1.5m per year.

In addition, underground heat means that about 47% of solar heat is stored underground through the surface, which is 500% of the amount of energy we use. Such underground heat is free from pollution, can be continuously charged naturally, and can use about 400% of the energy saved during the hot summer during the winter, and most of the energy currently used depends on the generation power. By contrast, it can produce about 48% energy efficiency, and in the case of gas or oil, it can produce around 36% to 43% of heat, but when using underground heat, it can produce about 75% of heat.

Therefore, when the groundwater is discharged to the ground surface, it absorbs the above-mentioned underground heat, and a number of devices that can cool and heat the groundwater heat source by moving the groundwater heat source to the heat pump system by using the groundwater heat source that absorbed the ground heat by underground excavation have been proposed. have.

In the system where cooling and heating is performed by moving the groundwater heat source in the heat pump as described above, the groundwater is moved by the heat pump during heating to absorb and heat the heat source included in the groundwater, and the groundwater from which the heat source is removed is again underground. On the contrary, during cooling, the ground water is moved from the heat pump to absorb the cooling heat source included in the ground water to cool the ground water, and the ground water from which the cooling heat source is removed is moved back to the ground.

Thus, in the conventional system that can move and heat the groundwater heat source by the heat pump system, the cooling and cooling efficiency can be obtained when the amount of groundwater is large, but the groundwater heat source is insufficient when operated under the same conditions in the place where the groundwater is low. This does not move the required heat source in the heat pump is a problem that can not be cooled and heated.

In addition, in the conventional heating and cooling system using the groundwater heat source, it is possible to produce cold water, but there is no system capable of producing hot water at the same time, so there is a problem in that a separate hot water supply device needs to be installed in a workplace requiring hot water.

In addition, if the groundwater contains calcite, the calcification generates scale in the heat exchanger, which drastically decreases the heat exchange efficiency and lifespan, and if the groundwater is located near the sea and contains chlorine, (Salt) component is a problem that all the components of the heat pump system corrosion is fast progressed significantly shortening the life of the system.

The present invention is to produce the hot water and cold water at the same time by using the ground water as a heat source in order to solve the above problems to make the heating and cooling as the produced cold and hot water, as well as to enable the use of hot water at all times, the production The technical problem is to provide a sealed cold and hot water tank that can accumulate the hot and cold water is used to prevent the heat pump is frequently stopped when there is less air-conditioning space during heating and cooling.

In addition, the present invention is to discharge the pumped ground water to the outside when the temperature of the geothermal source in the heat pump does not reach the appropriate temperature to increase the efficiency in the production of hot and cold water when the cooling and heating water is circulated in the underground dig at the time of discharge While solving the groundwater pollution problem generated, when the temperature of the geothermal source is above a certain temperature, about 80% of the groundwater is discharged to the bottom of the underground excavation site, and the remaining 20% of the pumped groundwater is discharged to the upper ground area. The technical task is to ensure that the groundwater is absorbed evenly above and below the excavation site and that the groundwater source is not at the required temperature, so that the discharged groundwater is discharged to the outside to evenly absorb underground heat. do.

In addition, the present invention prevents the generation of scale due to the calcification when the groundwater is contained in the sealed cold and hot water tank, and even when the groundwater is located near the sea and contains (chlorine) chlorine component corrosion Is not generated, and the heat exchanger composed of all of the 'S' type zigzag shape is selectively installed to maintain the residence time of the heat exchange medium and increase the surface area, thereby increasing the efficiency of heat exchange and contributing to fuel saving, as well as the heat pump. It is a technical task to extend the life of the system.

It is installed.

The present invention is to produce hot water and cold water at the same time using the ground water as a heat source, and to enable heating and cooling as the produced cold and hot water, so that hot water can be used at all times during cooling, while the temperature of the geothermal source in the heat pump If the temperature does not reach the proper temperature to improve the efficiency of hot and cold water production, the pumped ground water is discharged to the outside, and when the air is not discharged, the ground and water are continuously polluted when circulating to the underground excavation site. When the temperature of the geothermal source is below a certain temperature, about 80% of the groundwater is discharged to the bottom of the underground pit, and the remaining 20% of the pumped groundwater is discharged to the upper area of the underground to discharge the groundwater above and below the rig.

In addition, the hot water outlet 7 of the heater pump device 11 and the hot water outlet of the sealed hot water storage tank 13 is provided with a hot water supply pipe 7 for supplying heating water to the heating flow path 18, the heating flow path 18. On the other side of the hot water inlet pipe 6 for supplying the heating water via the heating flow path 18 to the hot water inlet of the sealed hot water storage tank 13 and the heater pump device 11 is installed.

In addition, the ground water discharge pipe 10 is installed on the other side of the sealed cold / hot water storage tanks 12 and 13 to discharge cold water or hot water to the outside when the geothermal heat source is insufficient during cold / hot water production, or the upper discharge port 10a and Groundwater discharge pipe 10 is discharged to the ground through the lower discharge port (10b) is installed.

In addition, inside the hermetic hot water storage tank 13, a heat exchanger 14 having a 'S' type zigzag shape is fixedly installed so that the residence time of the heat exchange medium is kept long and the surface area is increased to increase the heat exchange efficiency. On one side of the heat exchanger (14), a water supply pipe (8) for supplying living water such as tap water is installed, and on the other side of the heat exchanger (14), the water for water discharge pipe (9) is discharged by being heated with hot water and discharged. ) Is installed.

Here, reference numerals V1, V2, and V3 are electric valves controlled by the heater pump device 11, and V1 and V2 are sealed cold and hot water storage tanks 12 and 13 when the geothermal heat source is insufficient when producing cold and hot water. It is an electric valve for discharging cold water or hot water stored in the outside to the ground or through the upper discharge port 10a and the lower discharge port 10b, and V3 is an enclosed cold / hot water storage tank when the geothermal heat source is insufficient in the production of cold and hot water. An electric valve for discharging cold water or hot water stored in (12) (13) to the outside, and reference numerals P1 to P5 are controlled by the heater pump device 11 as a circulation pump.

The sealed air-conditioning and cold / hot water generation system using the geothermal source according to the present invention made as described above, the groundwater pumped through the pump (2) through the groundwater water supply pipe (5) sealed cold and hot water storage tank (12) (13) Are stored in.

At this time, the ground water stored in the sealed cold water storage tank 12 is supplied to the cooling passage 17 piped in the room through the cold water supply pipe 4 to cool the room, and then the cold water inflow according to the operation of the circulation pump P3. Through the pipe (3) is introduced into the cold water inlet of the sealed cold water storage tank 12 and the heater pump device 11, the cooling circulating water introduced into the cold water inlet of the heater pump device 11 is formed with a lower temperature The cold water supply pipe 4 is supplied again to the cooling passage 17 piped indoors to repeat the process of cooling the room.

On the other hand, the ground water stored in the sealed hot water storage tank 13 is supplied to the heating flow path 18 piped to the room through the hot water supply pipe 7 to heat the room, and then the hot water is introduced according to the operation of the circulation pump P4. Through the pipe (6) is introduced into the hot water inlet of the closed hot water storage tank 13 and the heater pump device 11, the heating circulation water introduced into the hot water inlet of the heater pump device 11 is heated to a higher temperature It is formed and supplied again to the heating flow path 18 to be heated in the room through the hot water supply pipe 7 to repeat the process of heating the room.

When the heating process is repeatedly performed, the water stored in the sealed hot water storage tank 13 maintains a hot water state maintaining a predetermined temperature or more, and uses the hot water stored in the sealed hot water storage tank 13 to live. The water can be produced with hot water.

That is, the living water such as tap water supplied through the water supply pipe 8 is heat of hot water stored in the sealed hot water storage tank 13 in the process of passing through the heat exchanger 14 fixedly installed in the sealed hot water storage tank 13. By absorbing the living water flowing through the heat exchanger 14 is converted into hot water is discharged through the water discharge pipe (9).

Therefore, in the present invention, not only heating and cooling is performed as the geothermal source, but also hot water and cold water can be produced at the same time, so that the trouble of having to install a separate hot water supply device in case of hot water is required.

Figure 2a is a block diagram showing another embodiment of the hermetic heating and cooling and hot and cold water generation system using a geothermal source according to the present invention, Figure 2b (a), (b) of the sealed cold and hot water storage tank shown in Figure 2a. As a cross-sectional view, the cold and hot water and the cooling and heating passages 17 and 18 discharged from the heater pump device 11 by installing two heat exchangers 14a and 14b in series in the sealed cold and hot water storage tanks 12 and 13. The water stored in the cold / hot water storage tanks 12 and 13 as the circulating water via) will be made into cold water or hot water.

That is, two heat exchangers 14a and 14b are installed in series between the cold water supply pipe 4 and the cold water inlet pipe 3 installed in the hermetic cold water storage tank 12, and are in the hermetic hot water storage tank 13. Two heat exchangers 14c and 14d are installed in series between the installed hot water supply pipe 7 and the hot water inlet pipe 6.

In another embodiment of the present invention, the cold water supplied from the heater pump device 11 passes through the cooling channel 17 through the cold water supply pipe 4, and the cooling circulation water passing through the cooling channel 17 is a cold water inlet tube ( 3) through the two heat exchangers (14a, 14b) in turn through the heat exchange to the water stored in the sealed cold water storage tank 12 to absorb the cold heat through the heat exchanger (14a, 14b) occurs, the closed cold water The water stored in the storage tank 12 is made into cold water.

In addition, the hot water supplied from the heater pump device 11 is passed through the heating flow path 18 through the hot water supply pipe (7), and the heating circulation water passing through the heating flow path (18) is the hot water inflow pipe (6). By passing through two heat exchangers 14c and 14d in turn, heat exchange occurs in which water stored in the sealed hot water storage tank 13 absorbs heat through the heat exchangers 14c and 14d. The water stored in (13) is made into hot water.

That is, one embodiment shown in Figure 1a is directly using the water stored in the sealed cold and hot water storage tank 12, 13 as a cooling and heating circulating water, another embodiment shown in Figure 2a is a sealed cold. The water stored in the hot water storage tanks 12 and 13 is different from the fact that the water stored in the hot water storage tanks 12 and 13 is used as a heat exchange medium, and is always used in the sealed cold / hot water storage tanks 12 and 13 at all times. Since the heat exchange medium is stored in the geothermal source, not only heating and cooling can be performed, but also hot water and cold water can be produced at the same time. It can be.

In another embodiment of the present invention, the sealed cold and hot water storage tanks 12 and 13 are respectively provided with two heat exchangers 14a, 14b, 14c and 14d in series, but the cold and hot water storage tanks ( 12) According to the capacity of (13), three to five can be connected in series or in parallel, so the number of heat exchangers installed is not limited.

On the other hand, in the embodiment of the present invention shown in Figures 1a and 2a when the temperature of the geothermal source in the heat pump does not reach the appropriate temperature which can increase the efficiency in the production of hot and cold water, about 80% of the pumped groundwater underground The discharged groundwater is discharged to the bottom of the excavation site, and the remaining 20% of the pumped groundwater is discharged to the upper ground area so that the discharged groundwater is absorbed evenly by the heat source above and below the excavation site. When the heating efficiency drops, the geothermal source can be easily increased.

That is, when the heat source of the ground water is insufficient by measuring the temperature of the ground water pumped by the heater pump device 11, by selectively opening the electric valve (V1) (V2) stored in the sealed cold and hot water storage tanks 12, 13 The water is sent back to the basement through the groundwater discharge pipe (10).

When the water stored in the sealed cold and hot water storage tanks 12 and 13 is discharged underground, about 20% is discharged through the upper discharge port 10a, and about 80% is discharged through the lower discharge port 10b. At this time, about 20% discharged through the upper outlet 10a absorbs geothermal heat as it descends to the lower part of the groundwater drilling rig 1, and absorbs geothermal heat when raised by pumping, thereby reducing the amount of groundwater. If the geothermal heat source does not meet the required temperature and the cooling and heating efficiency is insufficient, the discharged groundwater can absorb underground heat to the maximum.

When the water stored in the sealed cold and hot water storage tanks 12 and 13 is discharged underground, the hot water stored in the sealed hot water storage tank 13 is discharged, and when it is intended for heating, it is sealed. Cold water is discharged into the cold water storage tank 12 to obtain a required heat source.

In addition, in the case of producing cold and hot water in the heater pump device 11, when the heat source of the ground water is very insufficient, the electric valve V3 is opened to selectively ground the water stored in the sealed cold / hot water storage tanks 12 and 13. The exhaustion of the gas to compensate for the lack of geothermal heat.

Here, the temperature range required for cooling and heating in the heater pump device 11 may vary depending on the capacity of the hermetic cold / hot water storage tanks 12 and 13 and cooling / heating capacity, and thus the temperature range is not limited.

3A is a perspective view showing heat exchangers 14 (14a to 14d) installed in the sealed cold and hot water storage tanks 12 and 13, and FIGS. 3B and 3B are front views of FIG. 3A. As shown in Fig. And plan view, a plurality of S-shaped pipes 21a to 21f formed in a zigzag shape of 'S' shape are arranged up and down at regular intervals, and the inside penetrates through one end of the S-shaped pipes 21a to 21f. The inlet pipe 22 through which the heat exchange medium is introduced is installed, and the outlet pipe 23 through which the inside is penetrated and the heat exchange medium flows out is installed at the other end of the S-shaped pipes 21a to 21f. A plurality of S-shaped pipes 21a to 21f arranged are provided with bands 24a and 24b for preventing flow and sag.

As described above, when the heat transfer medium flows in from the inlet pipe 22 installed at one end of the S-type pipes 21a to 21f, the heat exchanger 14 (14a to 14d) of each of the S-type pipes 21a to 21f. After moving through the flow path, it is discharged through the outflow pipe 23 provided at the other end of the S-type pipe (21a ~ 21f).

At this time, the heat transfer medium moving through each of the S-type pipes (21a ~ 21f) is formed in a zigzag form of the S-shaped long residence time and at the same time the surface area is increased to heat exchanger 14 (14a ~ 14d) It is possible to efficiently transfer heat to the surrounding heat transfer object.
