[Prior art]
In a house with conventional air circulation, the concept is that air taken from outside through the heat exchanger inside the house is diffused throughout the space under the floor, exhausted through the heat exchanger after going around the house. There has been a method in which air taken in through a heat exchanger is distributed to each space by a pipe and exhausted from each space again by a pipe.
[0003]
[Problems to be solved by the invention]
However, in the house like the former, although it is excellent in uniforming the temperature of the whole house, the flow rate of air in each indoor space is not adjusted, and the temperature in each indoor space should be adjusted. I could not. In the latter case, the temperature of each living space can be adjusted to some extent, but the piping is complicated, the construction period is prolonged, and the cost is increased. In addition, the temperature distribution in the indoor space is uneven, which is further required for heating. The air supply amount and the air supply amount required for exhaust were not balanced, and the efficiency was poor.

Reference numeral 5 denotes an inner wall space provided between the outer wall heat insulating layer 4b and the inner wall 10, which is a space where the cabin space 1 and the underfloor space 3 communicate with each other and air flows therethrough. The air rises, and in summer, it becomes a route through which the air sucked from the underfloor ventilation port 15 provided as needed rises.
[0010]
Reference numeral 6 denotes a heat source. For example, heat obtained from oil, gas, electricity, geothermal heat, solar heat, etc. is applied to the heat medium, and the heated heat medium α is supplied to the heat exchanger 7 through the pipe 6a. 7, heat is applied to fresh air taken from outside, and the air circulating in the house A is heated. As the heat medium α, for example, any one of water, antifreeze, air, and the like is selected.
[0011]
The heat exchanger 7 has a configuration as shown in FIG. 2, for example. That is, the heat exchanger 7 exchanges heat between the air supply pipe 17 and the exhaust pipe 18, thereby connecting the heat source unit 16 for exchanging heat between the air on the air supply side and the exhaust side, and the heat source 6 via the pipe 6a. Then, the heat supply unit 19 that applies heat to the air that has passed through the heat exchange unit 16 and a part of the exhaust from the exhaust port 14 are moved from the exhaust pipe 18 to the supply pipe 17, thereby performing heat exchange on the supply side. It is comprised from the connection pipe 20 which heat-exchanges the performed air more efficiently. Note that a fan 21 is disposed at an arbitrary portion of the air supply pipe 17. In addition, the role which guides fresh air to each space is possible with one of the supply pipes 17.

It is possible to prevent excessive drying of the wood constituting the casing.
[0016]
Here, the air circulation of the present invention will be briefly described. First, the fresh air taken in by the air supply pipe 17 exchanges heat with the exhaust discharged from the exhaust pipe 18 by the heat exchange unit 16, and adds a necessary amount of air from the connection pipe 20. After reaching the heat section 19 and being given heat necessary for heating the house A, it is diffused in an appropriate amount in each under-floor space 3.
[0017]
The air diffused in each underfloor space 3 rises in the wall space 5, and a part of the air is supplied from the vent 13 to the indoor space 2 and reaches the exhaust port 14. The air that has not been taken into the indoor space 2 heats the indoor space 2 by radiant heat from the inner wall 10, the ceiling 11, the floor 12, and the like. Generally, the amount of warm air inflow / outflow required when heating the indoor space 2 by warm air is required to be larger than the amount of air inflow / outflow when ventilating the indoor space 2, and heating by warm air is required. Although the effect alone has a poor balance between heating and ventilation, and thus the efficiency is low, the effect of this radiant heat acts to reduce the amount of warm air supplied to the indoor space 2, and the simultaneous ventilation with heating is effective. It is possible to be performed efficiently.
[0018]
A necessary amount of air taken into the exhaust pipe 18 from the exhaust port 14 is returned to the supply pipe 17 by the connection pipe 20, and then heat exchange is performed with fresh air in the supply pipe 17 by the heat exchange unit 16. After that, it is discharged outside the house A.
