Next, the operation of this embodiment will be described.

[0028] Heating and Ventilation in Winter The hot water in the hot water tank 28 of the heat source 24 is circulated through the hot water circuit 30 as shown by the white arrow in FIG. 4 and the forced ventilation fan 25 is operated, as shown by the solid arrow in the figure.
The cool fresh air is led from the fresh air introduction duct 47 through the fresh air inlet 40 to the heat exchange case 38, where the filter 43
After being filtered by, it is temporarily warmed through the heat exchange element 37. The heated fresh air is pressurized by the forced ventilation fan 25 and is secondarily warmed through the radiating coil 29, and then becomes warm air and is discharged from the outlet 35 into the underfloor space 8.

By the way, the warm air from the air outlet 35 flows through the underfloor space 8, which forms a duct as a whole. In the meantime, warm air heat is stored in the floor frame, that is, the floor slab 4, which is configured as a heat storage body.

The air-conditioned warm air flowing through the underfloor space 8 flows through the ventilation space 44 formed in the floor panel 13 to flow into the space above the floor, that is, the living space 9 to heat the space 9. Underfloor space 8
Is transmitted to the space 9 above the floor as radiant heat through the floor plate 13 composed of the radiant panel, and the space 9 is efficiently heated over the entire area. When the temperature in the underfloor space 8 becomes lower than the temperature of the frame wall, that is, the floor slab 4, the heat stored in the floor slab 4 is dissipated to the underfloor space 8 through the heat absorbing / radiating layer 3.

The air that has heated the above-floor space 9 flows through the plurality of vents 46 of the ceiling plate 19 to the ceiling space 10 as shown by arrows in FIGS. The ceiling panel 19 receives warm air and is kept warm.

By the way, the warm air flowing into the ceiling space 10 is guided to an air flow passage P formed by the partition wall 14 and a plurality of ventilation windows 49 opened in the partition wall 14 as shown by arrows in FIG. flows smoothly over the entire region of the ceiling space 10 toward the air inlet 45 ₁ of the vertical duct 45.
In the meantime, the exhaust gas remaining and remaining in the ceiling space 10 is scavenged to the vertical duct 45, so that the polluted exhaust gas in the ceiling space 10 and the fresh air can be exchanged efficiently.

The exhaust from the ceiling space 10 is supplied to a vertical duct 45
After passing through to the underfloor space 8 and passing through the heat exchanger 26 and performing heat exchange with the outside air, it flows through the exhaust duct 48 to the balcony underfloor space 23 and is discharged therefrom to the outside air.

By the way, the skeleton wall F is formed by stacking a heat insulating layer 2 on the outer surface of the skeleton wall main body 1 and a heat absorbing / radiating layer 3 on the inner surface thereof. Due to the high heat insulation structure, while warm air circulates through the underfloor space 8, the overfloor space 9, and the ceiling space 10, the warm air heat is stored in the frame wall F, and the heat is dissipated to the outside air. It is reduced as much as possible. Then, for example, especially at night when the outside air is at a low temperature, the entire housing space H can be kept at an appropriate temperature by radiating heat from the heat storage body.

[0035] Cooling and Ventilation in Summer The chilled water in the chilled water tank 31 of the heat source 24 is circulated to the chilled water circuit 33 as shown by a chain line in FIG.
5, the hot fresh air flows from the fresh air introduction duct 47 through the fresh air inlet 40 to the heat exchanger 26, where it exchanges heat with the exhaust gas and is cooled down temporarily. Then, the air is sent to the heat radiating coil 32 by the forced ventilation fan 25, where it is secondarily cooled and blown out from the outlet 35 into the underfloor space 8.

By the way, the cool air from the outlet 35 flows through the underfloor space 8 which constitutes a duct as a whole, during which cool air heat is effectively stored in the floor slab 4 which constitutes a heat storage body.

The air-conditioned cold air flowing through the underfloor space 8 flows through the ventilation space 44 formed in the floor plate 13 to flow into the space above the floor, that is, the living space 9 to cool the space 9. Underfloor space 8
Is transmitted to the space 9 above the floor as radiant heat through the floor plate 13 composed of a radiant panel, and the space 9 is efficiently cooled over the entire area. When the temperature in the underfloor space 8 becomes higher than the temperature of the frame wall, that is, the floor slab 4, the heat stored in the underfloor slab 4 is dissipated to the underfloor space 8 through the heat absorbing / radiating layer 3.

The air that has cooled the above-floor space 9 is supplied to the ceiling plate 1 as shown by arrows in FIGS.
9 to the ceiling space 10 through a plurality of vents 46,
In the meantime, the ceiling plate 19 formed of the heat absorbing and dissipating panel receives cold air.

By the way, the cool air flowing into the ceiling space 10 is guided to an air flow passage P formed by the partition wall 14 and a plurality of ventilation windows 49 opened therein, as indicated by arrows in FIG. flows to the air introduction duct 45 ₁ of the vertical duct 45 flows through the space 10 cotton connexion smoothly on the whole. In the meantime, the exhaust gas remaining and remaining in the ceiling space 10 is scavenged to the vertical duct 45, so that the polluted exhaust gas in the ceiling space 10 and the fresh air can be exchanged efficiently.

The exhaust gas flowing through the vertical duct 45 flows into the heat exchanger 26 in the underfloor space 8.

The heat exchanger 26 exchanges heat with high-temperature fresh air, recovers waste heat, and discharges the exhaust air from the exhaust outlet 42 through the discharge duct 48 to the outside air.

By the way, the skeleton wall F is formed by stacking a heat insulating layer 2 on the outer surface of the skeleton wall main body 1 and a heat absorbing / radiating layer 3 on the inner surface thereof. Due to the high heat insulation, the cool air heat is effectively stored in the frame wall F, and the dissipation of the heat to the outside air is reduced as much as possible. And the whole house space H can be kept at an appropriate temperature by the heat radiation from the heat storage body.

Although the embodiment of the present invention has been described above, the present invention is not limited to the embodiment, and various embodiments are possible within the scope of the present invention. For example, in the above-described embodiment, the case where the present invention is applied to a single housing space of an apartment house has been described. However, this may be applied to a detached house, and the heat source, the forced ventilation fan, and the heat exchanger are conventionally known. The use of others is possible. Also, the case has been described where the skeleton wall has a three-layer structure of the skeleton wall main body, the heat insulating layer, and the heat absorbing / radiating layer. However, it is needless to say that this may be formed in another heat storage structure.
