Description

  The present invention provides a clean and energy-saving air conditioning system by performing heat exchange using a heat exchanger, in particular, a heat storage capsule encapsulating a heat storage material, and relates to the technical field of air conditioning equipment for building structures.

  Conventionally, an air-conditioning system using a heat storage capsule in which a heat storage material is sealed is a public land (see Patent Document 1). Here, a large amount of the heat storage capsules are arranged in the middle of the air passage where the air conditioner is installed (heat storage capsule group), and the air discharged from the air conditioner is applied to the heat storage capsule group to make a heat storage capsule. Is. In this way, heat is stored in the heat storage capsule using late-night power with a low power unit price, and the stored heat is used during the daytime when the power unit price is high.

  However, in the case of a known air conditioning system, not only when heat is radiated from the heat storage capsule but also when heat is stored in the heat storage capsule, all is performed via air, so there is a problem that the response is very poor. In other words, even if it is possible to cope with switching between heat storage and heat dissipation in large units such as night and daytime, if the span is shorter (for example, if you want to switch between heat storage and heat dissipation in units of 10 minutes), it should be sufficient. Can not. In short, it takes too much time to store heat via air.

  In addition, it is necessary to install a separate air conditioner at a position that is not so far from the heat storage capsule group (if the place is far away, heat cannot be stored efficiently, etc.), so the heat storage material and surrounding equipment are very There is also a problem that it requires a large installation space.

  Furthermore, in a known example, a heat storage material having the same temperature (18 ° C. or lower) as the melting point is enclosed in all the heat storage capsules, and this is heated by applying hot air from an air conditioner, or by applying cold air from an air conditioner. However, such an air conditioning system cannot be used effectively throughout the year. For example, when the heat storage material has a melting point of 18 ° C., even if it functions effectively for cooling in a hot season (for example, when air of about 30 ° C. is cooled by a heat storage capsule in which a heat storage material having a melting point of 18 ° C. is enclosed, It can be cooled to about 24 to 25 ° C.), which is insufficient for heating in the cold season (for example, cool air of about 8 ° C. is heated by a heat storage capsule in which a heat storage material having a melting point of 18 ° C. is enclosed) However, it can only be heated to about 14 to 15 ° C.). If the melting point of the heat storage material is lower than this, the disadvantage appears more remarkably.

  The present invention has been made to solve such problems.

  In order to solve the above problems, the present invention comprises a flat heat storage capsule having a through hole for inserting a heat transfer tube and encapsulating a heat storage material that changes from a solid phase to a liquid phase at a predetermined temperature, and a heat source. And a heat transfer tube connected to the heat transfer tube, wherein a plurality of the heat storage capsules are inserted into the heat transfer tube.

  Since such a configuration is adopted, the heat from the heat source reaching the heat transfer tube is quickly propagated over the entire surface of the heat transfer tube. Furthermore, since the heat transfer tubes are inserted into the through holes of the heat storage panel and are in contact with each other, they are quickly transmitted to the heat storage material via the heat storage capsule. Moreover, since the heat exchanger tube is arrange | positioned so that a thermal storage capsule may be inserted, it is compact. In addition, since the medium that transfers heat from the heat source to the heat transfer tube is a liquid such as water or oil, it has a very large heat capacity compared to a gas such as air and can carry the same amount of heat to the heat storage capsule in a small amount. . That is, since heat can be transferred to the heat transfer tube using a thin pipe or tube having a small surface area, the heat source can be installed at a remote location with little heat loss. That is, the degree of freedom of installation is high. In addition, since heat conductivity is high when liquid, such as water and oil, is utilized compared with the case where gases, such as air, are utilized as a heat transfer medium, the propagation | transmission of the heat from a heat source to a heat exchanger tube is also quick.

  In addition, a first heat storage capsule in which a first heat storage material having a first temperature as a melting point is enclosed, and a second heat storage material in which a second temperature lower than the first temperature is a melting point are enclosed. The second heat storage capsule is inserted and arranged with respect to the heat transfer tube, and as the heat source, a first heat source capable of supplying a temperature higher than the first temperature, and the second temperature. The heat storage type heat exchanger may be connected to a second heat source capable of supplying a low temperature.

  By adopting such a configuration, it is possible to provide a heat exchanger that can be effectively used for an air conditioning system throughout the year. For example, assume that the first temperature is set to 30 ° C. and the second temperature is set to 18 ° C. Since the melting point of the heat storage material in which the first heat storage capsule is enclosed is 30 ° C., heat (latent heat) of 30 ° C. can be stored by using the first heat source, and the cold air is brought to a sufficient temperature. Since it can be warmed up, it can be used for heating in winter. On the other hand, since the melting point of the heat storage material in which the second heat storage capsule is enclosed is 18 ° C., heat (latent heat) of 18 ° C. can be stored using the second heat source, and warm air is kept at a sufficient temperature. Since it can be cooled down to a low temperature, it can be used as a cooling system in summer.

  Further, the heat storage capsule may be a heat storage type heat exchanger characterized in that the peripheral edge of the through hole of the heat storage capsule constitutes a protruding portion protruding in the penetrating direction as compared with other portions.

  By adopting such a configuration, the peripheral edge of the through hole becomes “thick” in the penetration direction of the heat transfer tube. That is, since the contact area between the heat transfer tube surface and the inner peripheral surface of the heat storage capsule through-hole increases, heat can be more efficiently transferred (from the heat transfer tube to the heat storage material via the heat storage capsule). That is, the responsiveness of heat storage can be improved.

  In addition, the protruding portion protrudes only on one side of the heat storage capsule, and when the other heat storage capsule is overlapped on the protruding side, only the protruding portion comes into contact with the adjacent heat storage capsule. It is good also as a heat storage type heat exchanger.

  By adopting such a configuration, even if the heat storage capsule is inserted into the heat transfer tube and arranged in the same direction without a gap, a predetermined gap can be formed between the heat storage capsules. A large surface area capable of contacting with air can be secured. That is, heat exchange from the heat storage capsule to air (for air conditioning) can be performed efficiently.

  The protrusion may protrude from both sides of the heat storage capsule, and when the other heat storage capsules are overlapped, only the protrusion contacts the adjacent heat storage capsule. .

  By adopting such a configuration, even if the heat storage capsules are intubated into the heat transfer tubes and arranged without gaps, a predetermined gap can be formed between the heat storage capsules, so that contact with the air in the heat storage capsules A large possible surface area can be secured. That is, heat exchange from the heat storage capsule to air (for air conditioning) can be performed efficiently. Moreover, since the clearance can be secured even if the heat storage capsule is inserted into the heat transfer tube from any surface direction, the handling property is good.

  Moreover, it is good also as a heat storage type heat exchanger characterized by the fact that a plurality of types of heat storage capsules having a common inner diameter of the through holes and different sizes are prepared.

  By adopting such a configuration, a heat storage capsule having an appropriate size can be selected according to the installation location, so that the degree of freedom in installation is improved.

  Moreover, it is good also as a heat storage type heat exchanger characterized by the fact that a plurality of types of heat transfer tubes having a common outer diameter and different lengths are prepared.

  By adopting such a configuration, it is possible to select a heat transfer tube having an appropriate length according to the installation location, so that the degree of freedom in installation is improved.

  Further, the through hole is provided at substantially the center of the heat storage capsule, small holes are formed at the four corners of the heat storage capsule, and a support rod is inserted so as to straddle all the small holes located at the same corner. It is good also as a heat storage type heat exchanger characterized by this.

  By adopting such a configuration, it is possible to prevent changes in shape (twist and warp) over time of the flat heat storage capsule, and it is possible to maintain the initial installation state. For example, if the heat storage capsule is warped, the gap between the heat storage capsules may be reduced and the flow of air (for air conditioning) may be obstructed. However, the present invention can prevent such problems.

  Moreover, in order to circulate the air in a building, or in the middle of the ventilation path provided in order to ventilate the air in a building, the thermal storage type heat exchanger in any one of Claims 1-8 is provided. By providing an air conditioning system characterized by the arrangement, a clean and energy-saving air conditioning system that can be used throughout the year is provided.

  In addition, when storing a relatively high temperature from the reference temperature (for example, room temperature), it is literally “heat storage”, and when storing a relatively low temperature from the reference temperature, it is “cold storage”. In the claims, both are included and expressed as “heat storage”.

  According to the present invention, a heat storage heat exchanger that is compact and has excellent heat storage responsiveness can be realized. One heat storage type heat exchanger can be used for both cooling and heating.

It is the figure which showed the Example applied to the actual building based on the schematic block diagram of FIG.

  Hereinafter, an example of an embodiment of the present invention will be described with reference to the accompanying drawings. For easy understanding of the drawings, it should be noted that there are portions where the size and dimensions of each portion are exaggerated and there are portions that do not necessarily match the actual product. In addition, each drawing is viewed in the direction of the reference sign, and is expressed as upper, lower, left, right, near, and back based on the direction.

<Configuration of heat storage type heat exchanger>
As shown in FIG. 1, the heat storage type heat exchanger 50 is configured in a so-called “skewer shape” by inserting 20 flat, substantially rectangular heat storage capsules 60 into a round bar-like heat transfer tube 70 in layers. Yes. Support bars 52 whose entire surfaces are threaded are inserted into the four corners of the heat storage capsule 60 and fastened with nuts 54. In this embodiment, 20 heat storage capsules 60 are inserted into the heat transfer tube 70, and all of them have the same shape. In addition, one end of the heat transfer tube 70 is provided with an inlet for taking in liquid (hot water or the like) from a heat source, and the other end is provided with an outlet (details will be described later).

  As shown in FIG. 2, the heat storage capsule 60 is formed in a flat and rectangular shape and has a hollow portion 61 inside. The material is made of, for example, polyethylene resin. It has a size of about 282 mm in height, about 317 mm in width, and about 25 mm in thickness. A through hole 62 (53φ) for inserting the heat transfer tube 70 is formed in the approximate center in the front view. The peripheral edge of the through-hole 62 protrudes in a donut shape along a circle that is slightly larger than the through-hole 62 to form a protrusion 63. The protrusions 63 are formed on both surfaces of the heat storage capsule 60. Since the protrusion 63 is formed in this way, only the peripheral portion of the through hole 62 is formed thicker than other portions. Corners 65 having no hollow portions are formed at the four corners when viewed from the front, and small holes 66 are formed through the corners 65, respectively. An opening 64 for storing the heat storage material is formed on the upper surface of the heat storage capsule 60, and a cap (not shown) is attached after the heat storage material is sealed. The heat storage capsule 60 is formed with a plurality of close contact portions 67 and 68 formed by crushing the hollow portion 61 from the front side and the back side. These close contact portions 67 and 68 are provided for the purpose of improving the strength and the like of the heat storage capsule. Although not shown in the drawings, a plurality of linear irregularities along the left-right direction are formed on the front and back surfaces of the heat storage capsule 60 (at the same time, the inner peripheral surface side of the heat storage capsule 60 is also uneven. Formed)), earning contact area with air and heat storage material to be enclosed.

  Each of the heat storage capsules 60 is filled with a heat storage material having a predetermined melting point. In this embodiment, two types of heat storage materials are used: a heat storage material having a melting point of 30 ° C. (first heat storage material) and a heat storage material having a melting point of 18 ° C. (second heat storage material). One heat storage material is enclosed in one heat storage capsule 60. In the present embodiment, the first heat storage capsule 60a in which the first heat storage material is sealed and the second heat storage capsule 60b in which the second heat storage material is sealed are alternately inserted into the heat transfer tube 70. Yes. As a result, a total of 20 thermal storage capsules 60 are provided, a total of 10 first thermal storage capsules 60a and a total of 10 first thermal storage capsules 60a.

  Further, due to the presence of the protrusion 63 provided in the heat storage capsule 60, even when the heat storage capsule 60 is inserted into the heat transfer tube 70 and arranged without gaps, a predetermined gap G can be formed between the heat storage capsules (FIG. 4 (a)). As shown in FIG. 4B, it is possible to employ a configuration in which the protrusion 63 is formed only on one surface of the heat storage capsule 60.

  As shown in FIG. 3, the heat transfer tube 70 includes a round main body 72 having a chamber (hollow portion) 78 therein and a small-diameter core pipe 74 penetrating the main body 72 in the longitudinal direction. Stainless steel or aluminum is used as the material depending on the part. The working fluid 76 is sealed in the chamber 78, and at the same time, the inside of the chamber 78 is in a substantially vacuum state. Further, both ends of the core pipe 74 (that is, both ends of the heat transfer tube 70) are connected to a heat source, one of which functions as an intake port for taking in hot water shared from the heat source, and the other as an exhaust port. The temperature of the hot water supplied from the heat source is configured to be switchable between at least two temperatures, and in the present embodiment, it can be switched between 35 ° C. and 16 ° C. as necessary.

<Operation and function of heat storage heat exchanger>
When the hot water from the heat source reaches the core pipe 74 and enters the main body 72 of the heat transfer tube 70, the heat of the hot water is transmitted to the working fluid 76 through the surface (tube liquid wall) of the core pipe 74. Since the inside of the chamber 78 is in a substantially vacuum state, even if it is hot water at a low temperature, the working liquid boils instantaneously due to the heat, and a vapor flow (jet) is generated from the liquid interface. The generated steam flow includes latent heat from the heat source, moves in the chamber 78 at a speed close to the speed of sound, and transports heat. The latent heat contained in the vapor flow collides with the chamber 78 (that is, collides with the inner wall of the main body 72), and the heat is transferred to the main body 72 and simultaneously aggregates and liquefies. By repeating this, the heat carried from the heat source by the hot water is instantaneously transmitted to the outer peripheral surface E of the heat transfer tube 70.

  Since a plurality of heat storage capsules are inserted into the heat transfer tube 70, the heat transferred to the outer peripheral surface E of the heat transfer tubes moves to the heat storage capsule 60 side. Furthermore, since the heat storage material is enclosed in the heat storage capsule 60, finally, the heat carried by the hot water is stored by the heat storage material.

  The heat stored in the heat storage material is transferred to the air flowing through the surface of the heat storage capsule 60 via the surface of the heat storage capsule 60. Since the surface of the heat storage capsule 60 is formed with a plurality of projections and depressions (not shown), a large air contact area is ensured and heat can be efficiently transferred to the air. Yes.

  As shown in FIG. 6, the heat storage type heat exchanger 50 is arranged in the middle of the air passage P provided for circulating the air in the building or for ventilating the air in the building. An example will be described. (A) shows the operating state during heating in winter and the like, and (b) shows the operating state during cooling in the summer and the like.

  In the case of heating shown in FIG. 6A, hot water of 35 ° C. is supplied from the heat source, whereby the first heat storage capsule 60a and the second heat storage capsule 60a in which the first heat storage material (melting point 30 ° C.) is enclosed. Any of the second heat storage capsules 60b in which the heat storage material (melting point 18 ° C.) is sealed melts and liquefies. In this state, when cold air (15 ° C. in this case) is passed through the air flow path P, the air is warmed by receiving heat when passing through the heat storage capsule 60 (for example, 23 ° C.). It can be heated by circulating it. In addition, since melting | fusing point of the 1st heat storage material enclosed with the 1st heat storage capsule 60a is 30 degreeC, since many latent heat (30 degreeC) can be stored, the heat | fever was deprived to the air side sequentially. Even in this case, the temperature of 30 ° C. can be maintained for a long time.

  On the other hand, in the case of cooling shown in FIG. 6 (b), hot water of 16 ° C. is supplied from the heat source, whereby the first heat storage material (melting point 30 ° C.) enclosed in the first heat storage capsule 60a is liquefied. However, the second heat storage material (melting point 18 ° C.) enclosed in the second heat storage capsule 60b is melted and liquefied. In this state, when warm air (30 ° C. in this case) is passed through the air flow path P, when the air passes between the heat storage capsules 60, heat is taken away and cooled (for example, 23 ° C.). It is possible to cool by circulating in the air. In addition, since melting | fusing point of the 2nd heat storage material enclosed with the 2nd heat storage capsule 60b is 18 degreeC, since many latent heat (18 degreeC) can be stored, when it takes heat from the air side sequentially However, it is possible to maintain a temperature of 18 ° C. for a long time.

  Further, as shown in FIG. 5, in the present embodiment, the first heat storage capsules 60a and the second heat storage capsules 60b are alternately arranged one by one, so that all the gaps (gap G between the heat storage capsules G ) Can effectively exchange heat with air during heating and cooling.

  A plurality of types of heat storage capsules 60 having a common inner diameter and different sizes may be prepared, or a plurality of types of heat transfer tubes 70 having a common outer diameter and different lengths may be prepared. If comprised in this way, since the optimal combination can be selected according to the condition of each installation place, installation freedom improves.

  In the above description, the melting point of the heat storage material is assumed to be heating and cooling. However, other than this, the heat storage material can be used in a pattern such as “two-stage heating” or “two-stage cooling”. It is of course possible to use three or more types of heat storage materials.

<Configuration of air conditioning system>
Next, an air conditioning system S incorporating the above-described heat storage heat exchanger 50 will be described with reference to FIGS.

  The air conditioning system S includes a gap layer 122 provided in a partition surface that partitions the interior and exterior spaces of the building 10, and the gap layer 122 is further divided into at least two layers to form an indoor gap layer 124 and a non-indoor gap layer 126. A first air passage 170 that communicates with the partition structure 100 including the heat shield sheet 120 disposed to form the room-side gap layer 124 and that can send air into the room-side gap layer 124. And a second air passage 180 that communicates with the indoor air gap layer 124 and can exhaust air from the indoor air gap layer 124, and discharges the air in the second air air passage 180 to the outside. The first heat exchanger 130 for exchanging heat between the air in the second air passage 180 and the fresh air taken into the first air passage 170 from the outside, and for actively moving the air A blower, Obtain.

  As shown in FIG. 7, the partition structure 100 has the exterior finishing material 102 disposed on the most outdoor side. For example, a gypsum board is used as the exterior finishing material 102. A moisture permeable / waterproof sheet 104 is disposed on the inner side (indoor side) of the exterior finish material 102. Further, a wall structure material 108 made of water-resistant plywood or the like is disposed inside. The wall structure members 108 are disposed above and below the pillar 112 and are disposed on both the left and right sides (outdoor side and indoor side) of the pillar 112 while forming a certain gap with the spacer 110 interposed therebetween. An interior finishing material 118 is disposed through a void layer 122 further inside the wall body structure 108 disposed inside the column 112 (inside the room).

  The gap layer 122 is further “bisected” into a layer shape by the heat shield sheet 120. That is, it is divided into two by the heat insulating sheet 120 supported from the column 112 side by the first heat insulating sheet fixing material 114 and further from the interior finishing material 118 side by the second heat insulating sheet fixing material 116. In short, except for the portions that are partially supported by the first and second heat shield sheet fixing materials 114 and 116, the heat shield sheet 120 is positioned in the gap layer 122 in a non-contact manner. Yes. As a result, the thermal insulation sheet 120 is divided into the indoor side void layer 124 and the non-indoor side void layer 126. The heat shield sheet 120 is made of a material that can efficiently reflect radiant heat, such as a film having aluminum deposited on the surface thereof.

  The interior finish material 118 is formed with a discharge port 118a that partially penetrates the interior (indoor) and the interior side void layer 124. In the present embodiment, the discharge port 118a is provided below the interior wall surface (near the feet).

  Moreover, the indoor side space layer 124 of the partition structure 100 communicates with the intake passage 134 via the underfloor space (the space between the floor 16 and the foundation 18) 22 in the present embodiment. The underfloor space 22 and the intake passage 134 constitute a first air passage 170. Note that. Since the underfloor space 22 can function as a part of a duct, dustproof coating is applied. Similarly, the indoor side void layer 124 of the partition structure 100 communicates with the exhaust path 136 via a ceiling space (a space between the roof 12 and the ceiling surface 24) in the present embodiment. The ceiling space 24 and the exhaust path 136 constitute a second air passage 180. In the ceiling space 24, dustproof coating may be applied in the same manner as the underfloor space 22.

  The intake passage 134 and the exhaust passage 136 are both connected to the intake port 132 through the total heat exchanger 130, and the exhaust passage 136 is connected to the exhaust port 138 through the total heat exchanger 130. The total heat exchanger 130 is configured to be able to exchange total heat between fresh air sucked from the intake port 136 and exhaust from the exhaust passage 136. For example, when the exhaust temperature from the exhaust passage 136 is 25 ° C. and the intake air temperature from the intake port 132 is 35 ° C., the exhaust heat from the exhaust port 138 flows through the intake passage 134 by the total heat exchanger 130. The temperature of the air is 25 ° C. (heat exchange rate 100%). The total heat exchanger 130 has a built-in blower (not shown), sends air sucked from the intake port 132 to the intake passage 134, and sends air in the exhaust passage 136 to the exhaust port 138. It is possible to send. That is, it is possible to actively move air.

  A heat storage heat exchanger 50 is disposed in the underfloor space 22. That is, the heat storage type heat exchanger 50 is provided in the middle of the first air passage 170. In addition, the structure, operation | movement, function, etc. of the said heat storage type heat exchanger 50 are as having demonstrated above.

  A liquid (such as water or oil) is circulated through the heat storage type heat exchanger 50 through a circulation pipe 152. The circulation pipe 152 enters and exits the second heat exchanger 140 installed outdoors, and is configured to be able to exchange heat with heat obtained from a specific heat source (details will be described later). .

  The circulation pipe 152 is also branched to the heat radiation / radiation panel 160 side disposed in the room 20 separately from the heat storage heat exchanger 50 side. The heat radiation / radiation panel 160 is formed in a shape (for example, a wave shape) capable of increasing the surface area, and allows liquid to pass through the panel. That is, the heat managed by the heat storage heat exchanger 50 can be directly transferred to the room 20 by the heat radiation / radiation panel 160.

  The ceiling surface 14 of the room 20 is provided with a collection port 136a that communicates with the exhaust path 136 so that air (dirty air, etc.) in the room 20 can be collected.

  For the “specific heat source” connected to the second heat exchanger 140, for example, sunlight or geothermal heat can be used for heating. That is, water or oil warmed by sunlight or geothermal heat can be used as a heat source for the second heat exchanger 140.

  Similarly, for cooling, for example, well water, river water, lake water, seawater, tap water, and the like can be used. That is, water or oil cooled by well water, river water, lake water, seawater, or tap water can be used as a heat source for the second heat exchanger 140. That is, for example, a certain amount of well water, river water, lake water, sea water, tap water, etc. is stored in a water tank or the like, and the temperature of the water or oil in the circulation pipe 152 is cooled by passing the circulation pipe 152 through the water tank.

  Of course, in addition to these, it is also possible to convert natural energy (sunlight, wind power, hydraulic power, wave power, etc.) into electric power, operate the electric chiller with the electric power, and use the electric chiller as a specific heat source. is there.

  In addition, as shown in FIG. 8, the air conditioning system S according to the present invention can be applied to a multi-storey building without any problem.

<Operation and function of air conditioning system>
The air conditioning system S according to the present invention can be used throughout the year. The following description will be made on the assumption that the air is cooled in a warm period. However, in the case of heating in a cold period, the temperature relationship is basically reversed. Therefore, a duplicate description is omitted.

  For example, the outside air temperature is assumed to be 30 ° C. Under these circumstances, the room 20 rises with time due to the heat radiated from the structure itself such as the roof and walls heated by sunlight, in addition to the heat transfer of the outside temperature, and in some cases the outside temperature. Above 30 ° C. However, for example, when well water is used as a specific heat source, the temperature at the time of supply is about 16 ° C. even in summer, and there is a difference of 10 ° C. or more between the outside air temperature.

  In the air conditioning system S, the temperature (thermal energy of the specific heat source) of the specific heat source (here, tap water) is used to the maximum for the air conditioning. That is, when the power supply of the air conditioning system S is turned on, a blower (not shown) built in the total heat exchanger 130 is activated, and the air in the first air passage 170 and the second air passage 180 is positively moved. Start moving to.

  At the same time, a pump (not shown) that circulates water and oil in the circulation pipe 150 is activated to transmit the thermal energy obtained from the specific heat source to the heat storage heat exchanger 50.

  Outside air (for example, 30 ° C.) sucked from the intake port 132 is discharged to the underfloor space 22 through the intake passage 134 and passes through the heat storage heat exchanger 50 arranged in the underfloor space 22. At the time of this passage, the temperature of the fin-like heat storage capsules 60 installed in the heat storage heat exchanger 50 is the temperature of a specific heat source (for example, 18 ° C.), so heat exchange is performed here. To be cooled.

  The cooled air sequentially moves from the underfloor space 22 that is a part of the first air passage 170 to the indoor air gap layer 124. The air that has entered the indoor space layer 124 rises in the space layer 124, and a part (or all of the air in some cases) is discharged into the room 22 from the discharge port 118a. Further, in the present invention, the void layer 122 provided in the partition surface that partitions the interior / exterior space of the building, and the void layer 122 is further divided into at least two layers to form the indoor space layer 124 and the non-indoor space layer 126. (That is, the indoor air gap layer through which air passes is disposed on the indoor side (inner side) of the heat shield sheet, and the heat shield sheet 120 is immediately Since a void layer (an anti-indoor side void layer 126) is provided on the outdoor side (outside) as well, radiation heat as well as conduction heat can be cut. That is, the temperature of the air in the indoor air gap layer 124 does not increase excessively due to the influence of the outdoors.

  The air discharged into the room 22 is recovered from the recovery port 136a formed in the ceiling surface 14 to the exhaust path 136 while being exchanged with the air that has been present in the room in the forward dimension. In addition, the air that has moved through the room-side air gap layer 124 without being released into the room 22 is finally collected in the exhaust path 136 via the ceiling space 24 (that is, in the flow of the second air path 180). get on).

  The temperature of the air collected in the exhaust passage 136 is, of course, increased due to heat radiated from the human body in the room, heat generated by the use of electrical products, etc., but it is still far from the outside temperature. It is a level that does not reach. If this heat energy is released to the outside air as it is, it will be very wasteful (the heat energy of the cooled air will be wasted). Therefore, in this air conditioning system S, the total heat exchanger 130 will try to capture it. Exchange heat with fresh air.

  Once this flow is completed, the burden on the regenerative heat exchanger 50 is extremely small, so that little heat energy is required as the specific heat source. In addition, since the interior and exterior are thermally insulated and shielded very efficiently by the gap layer 122 and the heat shielding sheet 120, the amount of heat flowing in from the outside and the amount of heat flowing out of the room are extremely small. Therefore, the amount of heat to be replenished is small, and a sufficient air conditioning system can be realized even with energy saving.

  Further, when the air conditioning system S is operating, ventilation is always performed between the outside air (fresh air). Therefore, ventilation (for example, 24-hour ventilation) can be realized at the same time without wasting thermal energy.

  In addition, although it demonstrated as a structure which provided the space | gap layer in the partition structure which partitions the inside and outside of a building above, this invention can utilize not only the indoor and outdoor partition structure but the partition structure of indoor spaces. Is possible. That is, a void layer provided in a partition structure that divides the space in the building, and a shield layer disposed so as to form an indoor side void layer and an anti-indoor side void layer by further dividing the void layer into at least two layers. A partition structure provided with a heat sheet; communicated with the indoor space layer; a first air passage capable of sending air into the indoor space layer; communicated with the indoor space layer; A second air passage that can exhaust air from the interior air gap layer, and the air in the second air passage are discharged to the outside, and the air in the second air passage and the first from the outside Even if configured as an air conditioning system comprising a first heat exchanger that exchanges heat with fresh air taken into one air passage, and a blower that actively moves air Well, it is also possible to apply both at the same time. In short, the present invention can be similarly applied not only to a partition structure (wall, roof, floor, etc.) that partitions the interior and exterior, but also to a partition structure that partitions the interiors of the rooms.

  In the partition structure 100 described above, the void layer is “bisected”. However, the present invention is not limited to this. If necessary, two or more heat shield sheets 120 can be arranged to constitute “three minutes” or more. In short, as long as the heat shielding sheet 120 exists outside the air gap layer through which air passes, various structures can be adopted.
