FIG. 4 is a plan view illustrating an outline of the entire building air conditioning system 10 in the attic space 61 on the 1st floor of the building 11 of the present embodiment.

FIG. 1 shows a state in which the entire building air conditioning system 10 is arranged in the building 11, and the building 11 is, for example, a double-decker house. The whole building air-conditioning system 10 mainly includes a ceiling-top convection system 14 that forcibly sends the inside air of the underfloor space 12 and the inside air of the hut back space 13 to each other, a heat exchanger 15 that is a first-class ventilation facility, and a building. Two air conditioners 16 and 17 arranged inside the building 11, an underfloor louver 20 arranged on the floor 26 on the 1st floor of the building 11, and a ceiling louver 21 arranged on the ceiling 27 on the 2nd floor of the building 11. , Equipped with. A plurality of ducts through which outside air, inside air, and air conditioning air flow are connected to the heat exchangers 15 and the air conditioners 16 and 17, and the entire building air conditioning system 10 is configured.

Here, the living room 18 of the present embodiment is a space in which the residents and residents of the building 11 continuously live, and when the building 11 is a house, for example, the living room L, the dining room D, and the living dining kitchen. LDK, bedroom R, study R, children's room R, etc. correspond to living room 18. When the building 11 is an office, for example, an office, an office, a conference room, or the like corresponds to a living room 18. When the building 11 is a hospital, for example, a waiting room, a treatment room, and an examination room correspond to a living room 18. When the building 11 is a restaurant, for example, the guest room and the kitchen correspond to the living room 18.

On the other hand, the non-living room 19 of the present embodiment is a space that does not correspond to the living room 18 of the building 11, and when the building 11 is a house, for example, a toilet WC, a dressing room M, a bathroom B, a corridor H, and a staircase. S, entrance hall E, kitchen K (excluding dining kitchen), walk-in closet WIC, staircase STR, etc. correspond to non-living room 19. When the building 11 is an office, a hospital, or a restaurant, for example, a toilet, a corridor, a warehouse, a changing room, and the like correspond to a non-living room 19.

As shown in the figure, as shown by the sand-like hatching 22, the members of the building 11 in contact with the outside air, such as the outer wall of the building 11, are composed of heat insulating members, so that the entire building 11 is insulated from the outside air and the like. It is formed as a heat insulating structure. With this structure, the internal space of the building 11 such as the underfloor space 12, the cabin back space 13, the living room 18 and the non-living room 19 is formed as a heat insulating space. By forming the foundation concrete of the underfloor space 12 of the building 11 in combination with the heat insulating material, the heat insulating efficiency of the underfloor space 12 is further improved.

The top-bottom convection system 14 is mainly arranged in a duct 23 that communicates the underfloor space 12 and the cabin back space 13 and an intermediate portion of the duct 23, and blows the inside air of the underfloor space 12 to the cabin back space 13. Alternatively, it has a forward / reverse fan 24 that blows the inside air of the cabin back space 13 to the underfloor space 12. The ducts 23 arranged in the underfloor space 12 and the cabin back space 13 are branched in the spaces and have a plurality of openings to supply the inside air as uniformly as possible in the spaces. Alternatively, the inside air can be sucked in as uniformly as possible from within those spaces.

As shown by a plurality of arrows 25 in both directions, in the top-bottom convection system 14, the forward / reverse fan 24 is driven in the forward rotation direction, so that the inside air of the underfloor space 12 is sucked into the duct 23, and the space behind the cabin is forcibly introduced. It is blown to 13. Then, the cabin back space 13 is filled with the inside air of the underfloor space 12 blown from the duct 23, and the inside air originally existing in the cabin back space 13 is passed through the ceiling louver 21 to the non-living room 19 of the building 11. It flows out to the living room 18.

On the other hand, when the forward / reverse fan 24 is driven in the reverse direction, the inside air of the cabin back space 13 is sucked into the duct 23 and forcibly blown into the underfloor space 12. Then, the underfloor space 12 is filled with the inside air of the cabin back space 13 blown from the duct 23, and the inside air originally existing in the underfloor space 12 passes through the underfloor louver 20 to the living room 18 or non-living room of the building 11. It flows out to 19.

In the present embodiment, when the outside air is in a higher temperature state than the inside air, such as in summer, the inside air in the cabin back space 13 is warmed by the heat from the roof 29 due to solar radiation, and is in a higher temperature state than the inside air in the underfloor space 12. Become. In this case, the resident of the building 11 usually operates the air conditioners 16 and 17 by cooling operation, and cools the inside of the building 11 by air conditioning in the entire building. At this time, since the cold air from the air conditioners 16 and 17 flows below the living room 18 and the non-living room 19, the inside air in the cabin back space 13 is difficult to be cooled by the operation of the air conditioners 16 and 17. On the other hand, a part of the cold air flows into the underfloor space 12 through the underfloor garage 20, and the inside air of the underfloor space 12 is cooled through the floor 26 of the building 11 and the foundation concrete. The inside air of the space 12 is lower than the inside air of the space 13 behind the hut.

Therefore, as described above, the forward / reverse fan 24 of the top-bottom convection system 14 is driven in the forward rotation direction, and the inside air in the low temperature state of the underfloor space 12 is blown to the cabin back space 13 to lower the temperature of the cabin back space 13. It can be filled with the inside of the state. As a result, the living room 18 and the non-living room 19 of the building 11 are blocked from the roof 29 and the like of the building 11 in the high temperature state by the inside air of the low temperature state of the cabin back space 13, and the ceiling 27 of the building 11 is in the low temperature state. By being cooled by the inside air of the building 11, the entire building 11 is cooled, and the cooling efficiency of the air conditioners 16 and 17 is greatly improved. Further, since the inside air in the low temperature state of the cabin back space 13 flows appropriately without being trapped, the occurrence of dew condensation on the air conditioner 16 arranged in the cabin back space 13 is prevented, and the product life thereof is extended.

On the other hand, when the outside air is lower than the inside air, such as at night or in the early morning in winter or spring / autumn, the resident of the building 11 usually operates the air conditioners 16 and 17 by heating operation and air-conditions the entire building. The inside of the building 11 is heated. At this time, the warm air from the air conditioners 16 and 17 flows above the living room 18 and the non-living room 19, and a part of the air flows into the hut back space 13 through the ceiling louver 21, so that the hut back space 13 The inside air is warmed by the operation of the air conditioners 16 and 17. Further, the inside air of the cabin back space 13 is also warmed through the ceiling 27 warmed by the warm air.

At this time, in particular, the air conditioner 16 arranged in the cabin back space 13 senses the warm inside air of the cabin back space 13 and warms the living room 18 and the non-living room 19 on the second floor to the set temperature or the vicinity of the set temperature. By erroneously recognizing that the air conditioner is in the air conditioner 16, the air conditioning air from the air conditioner 16 becomes a breeze or stops. As a result, mainly the living room 18 and the non-living room 19 on the second floor are difficult to be heated by the air conditioner 16, and the cold state is not improved, so that the comfort of the resident is impaired.

Therefore, as described above, by driving the forward / reverse fan 24 of the top-bottom convection system 14 in the reverse direction and blowing the warm inside air of the hut back space 13 to the underfloor space 12, the air conditioner 16 in the hut back space 13 The inside air warmed by, 17 is not trapped, and the inside air of the hut back space 13 becomes a certain low temperature state due to the outside air and the roof 29. As a result, the above erroneous recognition does not occur in the air conditioner 16, and warm air having an appropriate air volume is supplied from the air conditioner 16 to the living room 18 and the non-living room 19 on the second floor, and the living room 18 and the non-living room 19 on the second floor are supplied. It is warmed to the desired temperature, improving the comfort of the inhabitants.

Further, in the underfloor space 12, warm inside air is blown from the cabin back space 13, so that the underfloor space 12 is filled with warm inside air. As a result, the floor 26 on the first floor of the building 11 and the foundation concrete of the underfloor space 12 are warmed, and the floor heating effect can be obtained in the living room 18 and the non-living room 19 on the first floor.

In the top-bottom convection system 14, the forward / reverse fan 24 is driven in the forward rotation direction when the air conditioners 16 and 17 are blown and the air conditioners 16 and 17 are stopped, and the inside air of the underfloor space 12 is transferred to the cabin back space 13. And blow air. With this system, the inside air of the underfloor space 12 close to room temperature or the inside air of the cabin back space 13 always flows in the duct 23, so that dew condensation is less likely to occur in the duct 23, and the effect of preventing mold on the duct 23 is obtained. Be done. In addition, the inside air of the underfloor space 12 is less likely to be trapped, and the humidity inside the underfloor space 12 is adjusted so that the inside air of the underfloor space 12 is less likely to have an unpleasant odor due to humidity or the like.

FIG. 2 shows the piping status of the duct 23 and the like in the underfloor space 12 and the arrangement status of the underfloor louver 20 on the floor 26 of the building 11. In FIG. 2, for convenience of explanation, both the underfloor space 12 and the structure of the first floor of the building 11 located above the underfloor space 12 are shown by solid lines.

As shown in FIG. 2, the forward / reverse fan 24 of the top-bottom convection system 14 is arranged in the middle of the duct 23 piped in the underfloor space 12. Further, in the underfloor space 12, a turnout 31 is arranged at a substantially central portion thereof, and the duct 23 is connected to one connection port of the turnout 31. As shown in the figure, for example, four ducts 32, 33, 34, 35 are connected to the turnout 31, and no ducts are connected to the two connection ports 36, 37 of the turnout 31.

Further, the ducts 32 and 33 extend along the corridor H, which is the non-living room 19, to the living / dining / kitchen LDK side, which is the living room 18 on the left side of the paper. The connection ports 36 and 37 of the turnout 31 are arranged so as to face the front-rear direction of the paper surface. The ducts 34 and 35 extend along the corridor H, which is the non-living room 19, to the entrance hall E and the stairs S, which are the non-living rooms 19 on the right side of the paper.

According to the above piping structure, in the underfloor space 12, the connection ports 36, 37 of the turnout 31 in the non-connected state of the duct and the tip openings of the ducts 32 to 35 are arranged in substantially all directions of the underfloor space 12. The underfloor space 12 is finely divided by the foundation concrete of the building 11, but in the top-bottom convection system 14, the inside air of the underfloor space 12 is sucked in as uniformly as possible, or the inside air of the cabin back space 13 is filled in the underfloor space 12. be able to. As a result, in winter, substantially the entire underfloor space 12 including the foundation concrete can be heated, and the floor heating effect can be obtained over substantially the entire floor 26 of the building 11.

Further, a plurality of underfloor louvers 20 are arranged on the floor 26 of the living room 18 and the non-living room 19 on the first floor of the building 11. As shown in the figure, the underfloor louver 20 is mainly arranged at the tip of the tip opening of the turnout 31 or the ducts 32 to 35. With this structure, in the top-bottom convection system 14, in winter, the warm inside air of the underfloor space 12 is blown to the living room 18 and the non-living room 19 on the first floor of the building 11 via the underfloor louver 20. For example, in the toilet WC, the dressing room M, and the bathroom B of the non-living room 19, in addition to the floor heating effect, the warm inside air from the underfloor space 12 is blown, so that an effect of preventing heat shock can be obtained.

On the other hand, in the top-bottom convection system 14, in the summer, the cold air accumulated near the floor 26 of the living room 18 and the non-living room 19 on the first floor is sucked into the underfloor space 12 through the underfloor louver 20, and the cold air is sucked into the underfloor space 12 and the above-mentioned cold air is sucked into the underfloor space 13. The cold air from the air conditioners 16 and 17 can be circulated in the building 11. As a result, it is prevented that the feet of the resident of the living room 18 on the first floor become too cold, and the comfort of the resident is improved. As the underfloor louver 20, for example, a resin floor ventilation material such as PP (PolyproPyrene) is used, which corresponds to the second air distribution section of the present invention.

FIG. 3 shows the piping status of the duct 23 and the like in the cabin back space 13 and the arrangement status of the ceiling louver 21 on the ceiling 27 of the building 11. In FIG. 3, for convenience of explanation, both the structure of the back space 13 of the cabin and the second floor of the building 11 located below the space 13 are shown by solid lines.

As shown in FIG. 3, the duct-type heat exchanger 15, the air conditioner 16, the duct 23 of the top-bottom convection system 14, and the like are mainly arranged in the cabin back space 13. The heat exchanger 15 has an air supply duct 41 that sucks in the outside air outside the building 11 and supplies it to the air conditioners 16 and 17, and an exhaust duct 42 that sucks in the inside air inside the building 11 and discharges it to the outside of the building 11. Has. As the heat exchanger 15, for example, product number V-150CRL-D manufactured by Mitsubishi Electric Corporation can be adopted. The air conditioner 16 is mainly used for heating and cooling the living room 18 and the non-living room 19 on the second floor of the building 11.

The heat exchanger 15 exchanges heat between the outside air in the air supply duct 41 and the inside air in the exhaust duct 42 in the device. Then, when the outside air is higher than the inside air, such as in summer, the heat exchanger 15 cools the outside air to some extent and supplies it to the air conditioners 16 and 17 in a state close to room temperature, and the outside air is more than the inside air in winter, etc. In the case of low temperature, the air conditioning efficiency of the air conditioners 16 and 17 is improved by warming the outside air to some extent and supplying the air to the air conditioners 16 and 17 in a state close to room temperature. In the whole building air conditioning system 10 of the present embodiment, the heat exchanger 15 always operates regardless of the operating state of the air conditioners 16 and 17, thereby satisfying the ventilation requirements of the Building Standards Act.

As shown in the figure, the turnouts 45 and 46 connected to the air conditioning air supply ducts 43 and 44 of the air conditioner 16 are arranged in the cabin back space 13. A plurality of air-conditioning air-feeding ducts 47 and 48 are connected to the turnouts 45 and 46, respectively, and the air-conditioning air-conditioning ducts 47 and 48 are connected to a plurality of air supply ports 49 and 50 arranged on the ceiling 27 of the building 11. Connect to each. Then, the conditioned air supplied from the air conditioner 16 is blown to the living room 18 and the non-living room 19 of the building 11 through the air supply ports 49 and 50. Further, exhaust ports 51 and 52 are arranged at least on the ceiling 27 of each living room 18 on the second floor of the building 11, and the air conditioning air return duct 53 connected to the exhaust ports 51 and 52 is connected to the air conditioner 16. ..

Further, the duct 23 of the top-bottom convection system 14 is arranged so as to extend a substantially central region of the cabin back space 13 in the front-rear direction of the paper surface in the left-right direction of the paper surface along the corridor H which is a non-living room 19. Then, in the duct 23 of the cabin back space 13, as shown by the double circles 54, the inside air of the cabin back space 13 is sucked in from the three tip openings, or the inside air of the underfloor space 12 is transferred to the cabin back space 13. Fill up. The cabin back space 13 is a space that is substantially integrated without any walls that partition the space, and by arranging the tip openings at the above three locations, the entire cabin back space 13 is made as uniform as possible in the summer. In addition to cooling, it is possible to prevent the generation of areas where the inside air is contained.
