  Hereinafter, a first best mode for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a sectional view showing a house to which a first embodiment of a building air-conditioning system according to the present invention is applied. FIG. 2 is a right side view showing the appearance of the house of FIG.

  The house 10 as a building shown in FIG. 1 is configured in a highly airtight and highly heat-insulated structure in order to ensure comfort particularly in winter. That is, the foundation 11 of the house 10 is not provided with a ventilation opening, and a heat insulating material 12 for foundation such as an extruded polystyrene foam is attached to the outer side surface thereof. As the foundation 11, a solid foundation is used in which the entire bottom surface of the building is a pressure plate made of concrete and steel bars. Further, the outer wall 21 and the roof 13 are provided with a waterproof (airtight) sheet and a heat insulating material on the outside (detailed later). Further, the foundation heat insulating material 12 of the foundation 11 covers the foundation 11 deeply in the ground so that the foundation 11 is not affected by heat near the ground surface. Note that the depth of the pressure plate of the foundation 11 from the ground is desirably 1 meter or more. This is because the pressure plate stably stores the geothermal heat in the ground.

  The house 10 is partitioned into a floor space 15 and a floor space 16 by a floor 14 provided on the foundation 11, and the floor space 16 further includes a first floor space 17 constituting a lower floor space and an upper floor space. It is divided into a second-floor space 18 and an attic space (loft) 19 that constitute it. The roof 13 is configured in a single flow type inclined in one direction, and the attic space 19 is provided below the single flow roof 13. This attic space 19 communicates with the second-floor space 18. The first floor space 17 and the second floor space 18 are partitioned into a plurality of rooms by partition walls.

  As shown in FIG. 2, windows (lighting windows) W <b> 1, W <b> 2, and W <b> 3 for collecting sunlight 70 are arranged on the outer wall 21 located on the south side of the house 10 from the first floor of the house 10 to the attic space 19. Is provided. Each window has a height from the floor of the floor to the vicinity of the ceiling of the floor.

  Moreover, as shown in FIG. 1, the single flow roof 13 is installed so that the uppermost point of the roof may become the south side. This is to make the height of the outer wall 21 located on the south side the highest. In addition, the rooms facing the windows W1, W2, W3 are atriums and are not partitioned on each floor, so they penetrate from the first floor to the attic space 19 and share the same space. It has become.

  As shown in FIG.1 and FIG.2, the house 10 is provided with the cool storage heat | fever wall 30, the heat collection body 40, the duct 60, etc. for air-conditioning a building, These consist of a cooling / heating means and a heating means. It constitutes a building air conditioning system. The air conditioning and heating means constituting the building air conditioning system will be described in detail below.

  In the house which consists of the said structure, the air conditioning system as an air conditioning means which used the cool storage heat wall first is explained in full detail using FIG. 3 thru | or FIG. 3 is a cross-sectional view of the house for explaining the air conditioning system of the building air conditioning system according to the present invention in the house shown in FIG. 1, and FIG. 4 is a plan view of the first floor of the house shown in FIG. FIG. 5 is a diagram for explaining cooling in the summer by the cold storage wall in the house of FIG. 3, and FIG. 6 is a diagram for explaining heating in the winter and daytime by the cold storage wall in the house in FIG.

  As shown in FIGS. 3 and 4, a cold storage wall 30 formed integrally with the pressure plate of the foundation 11 is provided on the first floor. The regenerator wall 30 integrally formed with the foundation 11 is a rectangular parallelepiped made of RC (steel reinforced concrete) and having a thickness of d, and extends from the foundation 11 through the floor 14 to the ceiling of the first floor. have. The surface of the cold storage heat wall 30 in the longitudinal direction L (width direction) of the cold storage heat wall 30 is the outer wall 21 of the window at a position facing the window W1 of the first-floor room shown in FIG. It is provided so that it may become parallel. Moreover, the cool storage heat | fever wall 30 is installed so that an appropriate distance may be maintained from the inner wall which has the window W1, as demonstrated below.

  The cooling and heating using the regenerator wall 30 uses the geothermal heat (cold air) of the foundation 11 stored in the regenerator wall 30 for cooling in the summer, and stores the solar heat incident from the window in the winter and uses it for heating. is there. For this reason, the regenerator wall 30 is installed at a position where the regenerator wall 30 is not irradiated with the sunlight 70 in the summer, and the regenerator wall 30 is directly irradiated with the sunlight 70 in the winter (detailed later). To do.) The cold storage heat wall 30 is also used as a partition wall of the first floor space 17.

  First, cooling in summer using the cold storage heat wall 30 will be described with reference to FIG. In summer, the temperature of the foundation 11 is cooled by geothermal heat and becomes lower than the outside air temperature (about 15 to 17 ° C.), so the regenerator wall 30 formed integrally with the foundation 11 is almost equal to the temperature of the foundation 11. It becomes the same temperature. Therefore, as shown in FIG. 5, the air in the room of the first floor space 17 facing the cold storage wall 30 is cooled by contacting the surface of the cold storage wall 30, and the temperature of the room in the first floor space 17 is It becomes lower than the outside air temperature, and the room of the first floor space 17 is cooled.

  However, when the regenerator wall 30 is directly irradiated by the sunlight 70 incident from the window W2 located on the second floor shown in FIG. 3 or when the room temperature rises due to sunlight entering the room, the regenerator wall 30 is warmed and its surface temperature rises. In order to avoid this, a collar 32 is provided on the outer wall 21 at the top of the window. The incident angle θ (shown in FIG. 5) of the solar sunlight 70 passing through the meridian at the summer solstice is about 78 degrees, and the position of the eaves 32 so that the solar sunlight 70 passing through the meridian at least at the summer solstice does not enter the window. The width and the length of the flange 32 in the direction perpendicular to the outer wall 21 are determined.

  For example, as shown in FIG. 5, when the incident angle θ of the sunlight passing through the meridian on the summer solstice is 78 degrees and the height from the ridge 32 to the bottom of the window is 2 meters, By setting the length in the vertical direction to 43 centimeters, sunlight passing through the meridian at the summer solstice does not enter the room through the window. For this reason, by providing the eaves 32, the incidence of sunlight into the room during the summer can be reduced.

  Note that the ridge 32 may be a fixed type, but a variable type ridge capable of changing the length of the ridge 32 is more preferable because it can cope with climate change and the like.

  Thus, in summer, the cool air released from the regenerator wall 30 cools the space on the floor in combination with the suppression of the temperature rise of each room of sunlight by the ridge 32.

  Next, heating in winter using the cold storage heat wall 30 will be described with reference to FIG. In the winter season, the cold storage wall 30 formed integrally with the foundation 11 has substantially the same temperature as the foundation 11 (about 15 to 17 ° C.). Moreover, when the cool storage heat wall 30 is directly irradiated with sunlight 70, the cool storage heat wall 30 is warmed, the surface temperature rises, and solar heat is accumulate | stored. The incident angle θ of the solar sunlight 70 passing through the meridian at the winter solstice is about 32 degrees with respect to the cold storage wall 30 provided perpendicular to the ground, and the sunlight 70 before and after the winter solstice is not blocked by the eaves 32. The cold storage wall 30 is irradiated through.

  For example, as shown in FIG. 6, the incident angle θ of sunlight passing through the meridian at the winter solstice is 32 degrees, and the height from the upper surface of the regenerator wall 30 to the upper frame of the window W2 located on the second floor is 2 meters. Then, the upper part of the cold storage wall 30 located at a distance of 3.2 meters from the inner wall having the window can be irradiated with sunlight 70 incident from the upper part of the window W2. If the height of the window W2 located on the second floor is 1.5 meters, the sunlight 70 from the window W2 directly irradiates the surface from the upper surface of the cold storage heat wall 30 to 1.5 meters in the floor direction. It becomes possible. Thereby, in the winter season, it is possible to directly irradiate the cold storage wall 30 with sunlight incident from the window. In addition, the regenerator wall 30 can be irradiated with sunlight without being affected by the wall 32 provided to reduce the incidence of sunlight into the room during the summer.

  Thus, in winter, since the incident angle of the sunlight 70 with respect to the cool storage heat wall 30 provided perpendicularly to the ground is small, the solar storage wall 30 is not affected by the blockage of the sunlight 70 by the eaves 32 or the like. Light is directly irradiated, and the amount of light per unit area of the regenerator wall 30 increases, so that solar heat can be taken in efficiently. Thereby, the cold storage heat wall 30 is warmed by the sunlight 70 in the daytime, and thermal radiation and heat storage by the cold storage heat wall 30 are performed. In addition, since the temperature of the foundation 11 portion in winter is maintained at a substantially constant temperature, the temperature difference between the foundation 11 and the cold storage wall 30 is small, and the amount of heat transferred from the cold storage wall 30 to the foundation 11 is small. Even at night, the heat radiation from the cold storage wall 30 can be sustained.

  The heat stored in the cold storage wall 30 by sunlight 70 in the daytime in winter is radiated at night to warm the room. Thus, the warm air released from the cold storage heat wall 30 heats the floor space 16 in winter.

  In addition, although the cold storage heat wall 30 described what has the height to the ceiling of the 1st floor, in this invention, the height of the cold storage heat wall 30 is not limited to the ceiling of the 1st floor, for example, 2 It may be formed so as to reach the ceiling of the floor. The thickness and width of the cold storage wall 30 are determined in consideration of the heat storage capacity of the cold storage wall 30, the size of the room, and the like.

  The cooling and heating system using the regenerator wall described above performs cooling and heating using solar energy and geothermal heat, which are natural energy. Next, regarding a heating system as a heating means using a solar heat collector This will be described in detail with reference to FIGS. FIG. 7 is a diagram showing a configuration of a heating system using a heat collector, a heat collector, a partially enlarged view showing the flow of air in the duct, and FIG. 8 is a diagram showing a configuration of the heat collector, (A) is a front view of the heat collecting body, (b) is a right side view of the heat collecting body, (c) is a view shown by removing the upper plate from the view shown in (a), and FIG. It is a figure which shows the state which attached the heat collecting body to the outer wall of a house.

  As shown in FIG. 7, the heating system using the heat collector has a heat collector 40 that collects sunlight 70 and an openable and closable air that introduces air from the ventilation layer of the heat collector into the upper floor space. It consists of a mouth 66 and a duct 60 provided in the room.

  As shown in FIGS. 8A and 8B, the heat collector 40 is a rectangular parallelepiped and includes an upper plate 41, a bottom plate 42, a partition plate 43, and an outer frame 44. The upper plate 41 is made of a material having a high thermal conductivity such as an iron plate or a stainless steel plate, and is irradiated with sunlight 70 to collect solar heat. The bottom plate 42 is a portion in contact with the outer wall 21 and is made of a heat insulating material such as wood or plastic. The partition plate 43 is for forming a ventilation layer 53 for air flowing inside the heat collector 40. The outer frame 44 includes a water upper edge 45, a water lower edge 46, and side edges 47 and 48, and is formed of a heat insulating material.

  As shown in FIG. 8A, the heat collector 40 has a ventilation layer 53 formed on the entire surface. The heat collector 40 is configured by arranging a plurality of partition plates 43 as a ventilation layer forming member in parallel with the water upper edge 45 and the water lower edge 46 between the bottom plate 42 and the upper plate 41. The ventilation layer 53 is formed by being partitioned by a plurality of partition plates 43 in a space between the bottom plate 42 and the upper plate 41.

  In the heat collector 40, side edges 47 and 48 are installed on both sides of the outer edge 44 and the lower edge 46 on both sides orthogonal to the upper and lower edges 45 and 46, respectively. A plurality of adjacent partition plates 43 are in contact with the side edges 47 or 48 alternately, and a ventilation gap 54 is formed between the non-contact side edges 47 or 48.

  As shown in FIG. 8C, the bottom plate 42 is provided with an air inlet 49 near the lower edge 46 and an air outlet 50 near the upper edge 45. The air inlet 49 provided in the bottom plate 42 is for taking in air from the room into the heat collector 40, and the air outlet 50 provided in the bottom plate 42 flows through the ventilation layer 53 of the heat collector 40. It is for exhausting air.

  Further, as shown in FIG. 8A, the upper plate 41 is provided with a lower open / close lever 51 at a position near the air inlet 49 of the bottom plate 42, and near the air outlet 50 of the bottom plate 42. An upper opening / closing lever 52 is provided at each position. A lower opening / closing lever 51 provided on the upper plate 41 is for introducing outside air in summer and preventing outside air from flowing in in winter. Further, the upper opening and closing latch 52 provided on the upper plate 41 is for discharging air of the heat storage body in the summer and not discharging the air of the heat storage body to the outside in the winter.

  In this way, the heat collector 40 heats the air flowing in from the air inlet 49 or the lower opening / closing clasp 51 by the upper plate 41 that receives sunlight, and the air flow indicated by the arrows in FIG. As described above, the airflow layer 53 formed by the partition plate 43 is meandered by the upward flow of the heated air while flowing from the bottom to the top, and the heated air is discharged from the air outlet 50 or the upper opening / closing barrier 52. Is.

  The duct 60 shown in FIG. 7 is made of a material having a high thermal conductivity such as aluminum and is formed in a bellows shape. By forming the bellows shape, the surface area of the duct 60 is increased, and the heat dissipation efficiency can be increased.

  In addition, as shown in FIG. 7, the duct 60 is installed indoors and extends from the first floor space 17 which is the lower floor space to the attic space 19 which is the upper floor space through the second floor space 18. The upper opening 61 of the duct 60 is positioned below the vicinity of the outlet of the vent 66, and the lower outlet 62 of the duct 60 is connected to the air inlet 49 of the heat collector 40 through the wall.

  Next, installation of the heat collector 40 having the above-described configuration in a house will be described with reference to FIG. FIG. 9 is a cross-sectional view showing a state in which the heat collector is attached to the outer wall of the house. As shown in FIG. 9, the outer wall 21 to which the heat collector 40 is attached has a structural plywood 22 laid on a beam 26, and a plastic-based heat insulating material 24 is installed on the structural plywood 22 via a waterproof sheet 23. It has a structure. Further, a fiber-based heat insulating material 27 is incorporated between the indoor side of the structural plywood 22 and the inner wall 25 such as a gypsum board. The heat collector 40 is attached to the outer wall 21 so that the bottom plate 42 of the heat collector 40 is in close contact with the surface of the plastic heat insulating material 24.

  Thus, as shown in FIG. 2, the assembly 40 is arranged on the left and right of the windows W1, W2, W3 of the house 10, and on the outer wall 21 facing the south side from the first floor to the attic space 19 avoiding the windows. It is attached. In addition, in the house 10 shown in FIG. 2, although the two aggregates 40 are used, the aggregate | assembly can be used from one.

  As shown in FIG. 7, the heating system using the heat collector in winter functions as follows in order to heat each room of the floor space. Note that the lower opening / closing latch 51 and the upper opening / closing latch 52 of the heat collector 40 are closed. When the heat collection body 40 is directly irradiated with sunlight 70, the upper plate 41 of the heat collection body 40 is warmed and the surface temperature rises. The air flowing in from the air inlet 49 of the heat collector 40 is heated by the upper plate 41, and the air heated by the upper plate 41 meanders the ventilation layer 53 formed by the partition plate 43 by the upward flow of air. However, it flows from the bottom to the top and reaches the air outlet 50. The air heated by the heat collector 40 flows out from the air outlet 50 through the vent 66 to the space of the attic space 19, and the outflowed air is sucked from the upper opening 61 of the duct 60 and passes through the duct 60. As shown by arrows in FIG. 7, the air flows from the top to the bottom and flows from the lower outlet 62 of the duct 60 to the air inlet 49 of the heat collector 40.

  In this way, air (hot air) is circulated in the heat collector 40 and the duct 60 by the upward flow of the heated air in the heat collector 40. Thereby, the duct 60 is heated by the hot air that is formed in the bellows shape and flows through the duct 60, and heat is radiated from the surface of the duct 60 to heat the attic space 19, the second floor space 18, and the first floor space 17.

  Moreover, the heat collection body 40 exhibits an effect in solar heat collection in winter. That is, the incident angle θ of the solar sunlight 70 passing through the meridian at the winter solstice is about 32 degrees with respect to the heat collector 40 provided perpendicular to the ground. For this reason, in the winter period before and after the winter solstice, since the incident angle of the sunlight 70 with respect to the heat collector 40 provided perpendicular to the ground is small, the amount of light per unit area of the heat collector 40 is increased compared to the summer season, Solar heat can be taken in efficiently. Thus, the heat collection body 40 can utilize solar heat efficiently in winter.

In summer, the heat collector 40 is not used for heating. Therefore, the vent 66 is closed to prevent warm air from the heat collector 40 from flowing into the room. Further, the lower open / close clasp 51 and the upper open / close clasp 52 of the heat collector 40 are opened, the air near the ground surface is sucked from the lower open / close clasp 51 and discharged from the top open / close clasp 52. This is because air is always flowed through the ventilation layer 53 of the heat collector 40 to prevent heating of the upper plate 41 of the heat collector 40 and stagnation of air in the ventilation layer 53.

  The building air conditioning system according to the present invention can be used in combination with the cooling / heating system using the cold storage wall 30 shown in FIG. 3 and the heating system using the heat collector 40 and the duct 60 shown in FIG. That is, as shown in FIG. 1, in the summer, the cool storage heat wall 30 cools air by discharging the geothermal heat from the foundation 11 to the floor space 16, and in the winter daytime, the ventilation layer of the heat collector 40 is cooled. The warm air generated in is introduced into the floor space 16 through the duct 60 and heated by the radiant heat from the duct 60. In the winter night, the heat stored in the cold storage wall 30 is released to the floor space 16. Heating. Thus, in winter, it becomes possible to perform heating all day.

  As described above, according to the building air conditioning system of the present invention, as shown in FIGS. 1 and 3, it is formed integrally with the foundation 11, extends from the foundation 11, penetrates the floor, and is installed on the floor space 16. In the summer, the regenerator wall 30 radiates the cold air from the foundation geothermal heat on the floor so that the regenerator heat wall 30, the daylighting window for daylighting 70, and the eaves 32 provided directly above the daylighting window are provided. In the winter, the solar heat from the daylighting window is stored, and the stored heat can be released to the floor space 16 to use natural heat, geothermal heat and sunlight. Therefore, energy saving of air conditioning of building space is achieved. In addition, since no electric energy, oil, gas or the like is used, air conditioning costs can be saved.

  Moreover, since the cool storage heat | fever wall 30 is integrally formed with the foundation 11 by RC (steel reinforced concrete), it can be installed simultaneously with the construction of the foundation 11, and cost reduction can be achieved.

  Moreover, since the surface in the longitudinal direction of the regenerator wall 30 is provided so as to be parallel to the outer wall of the daylighting window, the sunlight directly irradiates the surface in the longitudinal direction of the regenerator wall 30 in winter, so Can be done efficiently.

  In addition, the ridge 32 can prevent the cold storage wall 30 from being irradiated and the room temperature from rising due to the incidence of sunlight in the room during summer.

  In addition, the heat collection body 40 including a ventilation layer 53 in which air flows by solar heat, the vent 66 for introducing the air from the ventilation layer 53 of the heat collection body 40 into the upper floor space 16, and the floor space 16 are provided. It is generated in the ventilation layer 53 of the heat collection body 40 during the daytime in winter so as to have the duct 60 introduced into the ventilation layer of the heat collection body 40 by sucking air from the ventilation holes 66 and flowing downstairs. Since the warm air circulates in the duct 60 and the ventilation layer 53 of the heat collector 40, the space 16 on the floor can be heated.

  Moreover, since the building air conditioning system of the present invention uses natural convection of air, it does not require a fan for circulating warm air. In addition, maintenance is easy because there are no movable parts such as an electric fan.

  Moreover, since the duct 60 is made of a material having a high thermal conductivity such as aluminum and is formed in a bellows shape, each room from the first floor to the top floor can be efficiently heated.

  Next, a second best mode for carrying out the present invention will be described with reference to the drawings. FIG. 10 is a cross-sectional view showing a house to which a second embodiment of a building air-conditioning system according to the present invention is applied. As shown in FIG. 10, the house 10 is provided with a regenerator wall 30 and a heat collector 40 for air-conditioning the building, and these constitute a building air-conditioning system comprising air-conditioning means and ventilation means. Is.

  Hereinafter, a ventilation system as a ventilation means using a heat collector will be described in detail with reference to FIGS. FIG. 11 is a sectional view of a house showing the air flow in the summer night of the ventilation system using the heat collector, and FIG. 12 is a house showing the air flow in the winter day of the ventilation system using the heat collector. FIG. 13 is a sectional view of a house showing a flow of air at night in winter of a ventilation system using a heat collector. In FIGS. 10 to 12, a part of the heat collector is enlarged so that the direction of air flow inside is indicated by arrows.

  In the house 10 having a high airtightness and high thermal insulation structure, a ventilation system is equipped in order to exhaust internal contaminated air and take in fresh fresh air.

  As shown in FIG. 10, the ventilation system includes a heat collector 40 that collects sunlight 70, an openable / closable ventilation port 67 that communicates with an air inlet 49 of the heat collector 40, and any outer wall 21. An outside air introduction port 65 for introducing outside air to the place is configured.

  The heat collector 40 used in the ventilation system is the same as that described above in terms of its configuration and the installation of the heat collector house. For this reason, description of the heat collection body 40 is abbreviate | omitted.

  As shown in FIG. 10, the ventilation port 67 is provided on the first floor of the house and communicates with the air inlet 49 of the heat collector 40. Moreover, it can be opened and closed as necessary. The outside air introduction port 65 introduces outside air, and is appropriately provided on the first floor and the second floor of the house 10.

The ventilation system sucks indoor air from an openable and closable vent 67 provided in the room by an upward flow of air heated by solar heat in the vent layer 53 of the heat collector 40, and passes through the air inlet 49 through the vent layer. 53, and the indoor air is exhausted to the outside from the upper opening / closing opening 52 of the heat collector 40. When the heat collector 40 is used as a ventilation system, the air outlet 50 of the heat collector 40 is not used. Therefore, the air outlet 50 is closed so that air does not leak from the air outlet 50. Also, the lower opening / closing lever 51 is closed,
The upper opening / closing lever 52 is kept open.

  As shown in FIG. 10, during the summer sunshine, the indoor air introduced into the heat collector 40 from the ventilation port 67 meanders through the ventilation layer 53 formed by the partition plate 43 while being warmed by solar heat. From the top to the bottom, the upper part opens and closes and reaches the outlet 52. The air heated by the heat collector 40 is released from the upper opening / closing opening 52 to the outside. Thus, the upward flow of the heated air of the heat collector 40 causes a flow of sucking air into the ventilation port 67, and the outside air from the outside air introduction port 65 flows through the room as shown by arrows in FIG. The indoor air is exhausted from the ventilation port 67 to the outside by the heat collector 40.

  In addition, at night in summer, the upper plate 41 of the heat collector 40 is cooled by radiation cooling, and the air in the heat collector 40 is also cooled and heavy. For this reason, as shown in FIG. 11, the cooled air flows from top to bottom while meandering the ventilation layer 53 of the heat collector 40. Due to the downward flow of the air, the outside air is sucked from the upper opening / closing clasp 52 of the heat collecting body 40, passes through the ventilation layer 53, is cooled into the ventilation port 67 from the air inlet 49, and is taken into the room.

  Thus, in the ventilation system according to the present invention, the heat collector 40 discharges indoor air to the outside during the daytime in summer, and guides the cooled outside air into the room at night.

  During winter sunshine, as shown in FIG. 12, the indoor air introduced into the heat collector 40 from the ventilation port 67 meanders through the ventilation layer 53 formed by the partition plate 43 while being warmed by solar heat. It flows upward from the top and is released from the upper opening / closing opening 52 to the outside.

  Further, as shown in FIG. 13, in order to prevent intrusion of cold air from the ventilation port 67 and outflow of indoor warm air from the ventilation port 67, the ventilation port 67 is closed at night in winter.

  As described above, in the ventilation system according to the present invention, during the sunshine in winter, a flow of sucking air occurs in the ventilation port 67 due to the upward flow of the heated air of the heat collector 40, and the outside air from the outside air introduction port 65 flows. Flowing through the room, the air in the room is discharged from the ventilation port 67 to the outside by the heat collector 40.

  As an embodiment of the ventilation system, the ventilation port 67 is provided on the first floor. However, in the ventilation system according to the present invention, a ventilation port is provided on the second floor by a duct or the like, and ventilation is performed from the second floor. Is also possible.

  The building air-conditioning system according to the present invention can be used in combination with the air-conditioning / heating system using the regenerator wall shown in FIG. 3 and the ventilation system using the heat collector shown in FIG. That is, as shown in FIG. 1, in the summer, the cold storage wall 30 discharges cool air from the foundation 11 to the floor space 16 for cooling, and in the winter night, the cold storage wall 30 stores heat. Heat is released to the floor space 16 for heating. Simultaneously with cooling and heating, indoor air can be discharged to the outside by the heat collector, and cooling and heating and ventilation can be performed with natural energy. Thus, in the building air-conditioning system according to the present invention, it is possible to simultaneously perform cooling and heating and ventilation.

  As described above, according to the building air conditioning system of the present invention, as shown in FIG. 10, indoor air is sucked into the heat collector 40 from the ventilation port 67 by the upward flow of the heated air of the heat collector 40. In addition, since it is configured to flow from the bottom to the top of the ventilation layer 53 and to be discharged to the outside by the heat collector 40, it is not necessary to install a ventilation fan or the like. Can be realized.

  The building air-conditioning system according to the present invention can perform air-conditioning and ventilation at the same time by using both the air-conditioning system and the ventilation system, and can perform air-conditioning without using a duct, a fan, or the like. Moreover, since the energy source is geothermal and solar heat which are natural energy, the running cost can be reduced.
