It is intended to be used as hot water.

The following describes the structure of the house A with this configuration.
As in the case of cooling in the summer, etc.
When processing is performed and heating is performed in winter, etc.
Is subjected to a heating process in winter.

(1) In Summer (Summer Cooling Process) In summer when the outside air temperature is high, the switch of the controller 6 is switched for summer. Thereby, the exhaust fan 250 is operated, and the air in the second floor attic ventilation passage 20 is exhausted to the outside.

When the circulation fan 491 operates, the second floor attic
Part of the air in the ventilation passage 22 is guided indoors through the solar heat collecting device 3, the heat exchanging device 4, the exhaust pipe 49 and the like . this
At this time, the air taken into the solar heat collecting device 3 is heated.
And it is sent to the heat exchanger 4 as hot air (hot air)
Be included. Then, the hot air is cooled by heat exchange with the cooling water in the heat exchange device 4 and changes into cool air (low-temperature air). The cool air is filtered by the air filter 490 and the first floor is discharged from the outlets 120 and 130. Introduced into rooms 12,13.

Here, the temperature of the air (outside air) immediately before being introduced into the solar heat collecting device 3 is T _G1 , the temperature of the air immediately after passing through the heat exchanging device 4 is T _G2 , and the cooling water in the heat exchanging device 3 is When the temperature is T _L , the above operation is performed under the condition of T _G1 > T _L , and control is performed such that the relationship of T _G1 > T _G2 (> T _L ) is established.

As described above, the ventilation in the ventilation path 2 is performed.
Introducing cool air indoors while discharging hot air outdoors
As a result, the room temperature can be lowered, and the burden on the air conditioner can be reduced. In some cases, a comfortable indoor environment can be obtained without operating the air conditioner.

The hot air is supplied to the heat exchange conduit 4 of the heat exchange device 4.
4 and the condensation chambers 43 and 43a, dehumidification is performed by cooling to form dew. The dew water drops and enters the vertical drain pipe 451 through the drain pipe 450, and the drain pump 4
52, it is discharged to the outside. in this case,
As described above, the end of the water distribution pipe 450 on the vertical pipe 451 side is
Since it is bent in a shape and arranged at a high position,
Dew water will always be stored in the main pipe part
Thereby, the pipe line between the water pipe 450 and the drain port 430 is formed.
Sealed. For this reason, the air passing through the heat exchange device 4 is not discharged outside through the water pipe 450.

On the other hand, hot water (cooling water) in the upper layer in the water tank 42 of the heat exchange device 4 is pumped up by the auxiliary water heater 5 and is heated by gas combustion or the like as necessary, and is used as hot water for living such as a bath. Further, when the cooling water is insufficient due to its use or the like, the tap water, well water, or the like is supplied into the water tank 42 as necessary so as to compensate for the shortage, thereby keeping the cooling water constant throughout.

[0050] Note that the cooling water in the heat exchanger 4, to be supplied if necessary, that the cooling water temperature T _L rises to ambient temperature (air temperature T _G1 of solar heat collector passes immediately before) However, it is possible to obtain a good cooling effect lower than the air temperature T _G1 throughout. Although the cooling water of the heat exchange device 4 is lower than the outside air temperature, the temperature of the cooling water is higher than that of tap water or well water due to heat exchange with air.
It can be used efficiently as hot water for daily use. Further, the cooling water of the heat exchange device 4 has a higher temperature in the upper layer portion than in the lower layer portion due to thermal expansion or the like. However, in the present embodiment, as described above, the cooling water in the high temperature upper layer portion is used. It can be more preferably used as domestic warm water.

(2) In Winter (Winter Heating Process) In winter when the outside air temperature is low, the switch of the controller 6 is switched for winter. Thus the circulation fan 251 is operated, to introduce the warm air upstairs roof back ventilation passage 20 in the lower side to the first floor underfloor air passage 24. At this time, the outside air intake of the base part 14
26 is automatically closed, and the exhaust port is
