Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating and cooling structure for a house using an air convection system that provides warmth in winter and cooling in summer without using any special heat or cold sources.

Up until now, various types of cooling and heating systems for houses have been developed that utilize solar heat, geothermal heat, and under-floor cold air, but all of them are only partially used and the structure of houses has not been designed to take full advantage of them. Utilization of indoor heating heat, house heat radiation, and insulation were not comprehensively considered, and the system had not yet become an efficient heating and cooling system. The present invention uses solar heat, geothermal heat, underfloor cooling,
The objective is to provide an efficient and excellent heating and cooling structure for a house by comprehensively considering the problems of indoor heating heat, insulation between indoor and outdoor spaces, heat radiation, and cooling.

This invention provides air flow passages 6, 6 that connect the underfloor space 4 and the attic space 5 between the south exterior wall material 2 and the room wall 3 and between the north exterior wall material 2' and the room wall 3' of the house 1. ', a partition wall 7 made of heat insulating material is provided in the middle of the air flow passage 6 on the south side, a heat insulating material 8 is installed inside the outer wall material 2' of the air flow passage 6' on the north side, and a roof sheathing board 9 is installed. , 9' and the roofing board 9 at a predetermined interval,
Attic insulation walls 10, 10' are provided along the south attic insulation wall 10, and the lower edge of the south attic insulation wall 10 and the partition wall 7 are connected to the girder 11.
further connected with the attic insulation walls 10, 1
Air supply fan 1 is installed at the top of the attic space 5 above 0'.
2 is provided, and a switching valve 13, 1 is provided to switch the air supply from the air supply fan.
The air outlet 15 of one air duct 14 is provided outdoors, and the outlet 1 of the other air duct 14' is connected to the two air ducts 14, 14' through
5' is provided in the underfloor space 4, and an electric damper 16 is further provided in the window communicating between the underfloor space 4 and the outdoors. In the figure, 17 is the floor material, 18 is the ceiling material, 19 is the taruki material, 20 is the heat dissipation collar attached to the air outlet 15, and 21 is the air outlet 1.
5' is a heat dissipation unit, 22 and 22' are temperature sensors, and 23 is a temperature sensor. Air supply fan 1
2. For the switching valves 13 and 13', the electric opening/closing operation of the electric damper 16 may be performed automatically using the temperature sensors 22, 22' and the temperature sensor 23, or may be operated manually.

In this invention, in the summer, the electric damper 16
is opened, the air supply fan 12 is operated, and the switching valve 1 is opened.
Close 3'. Due to solar heat and high outside air temperature in the summer, high-temperature air that is higher than the outside temperature is generated and stagnates in the space above the insulation walls 10, 10' in the attic and the outer passage space of the insulation partition wall 7 of the south airflow passage 6. When the air supply fan 12 operates, outside air enters the underfloor space 4 from the electric damper 16, and along with the relatively low-temperature air in the underfloor space, air flow passages 6 on both north and south sides,
At that time, the high-temperature air that remained in the air flow passages 6 and 6' also rises and flows into the attic, where it mixes with the high temperature air in the attic space 5 and cools it to the level of outside air. Furthermore, the insulation wall 10 of the attic space 5
The highest temperature air above is forcibly absorbed by the air supply fan 12, passed through the gate valve 13, passed through the air duct 14, and is discharged outdoors from the outlet 15. In addition, the south exterior wall material 2 and the attic roof board 9, which tend to become hotter than the indoor outdoor temperature,
The air near 9' is passed through the partition wall 7 made of heat insulating material, the heat insulating wall 10,
10' to prevent heat transfer indoors, and the air in these high-temperature areas is forcibly blown outdoors together with the underfloor air at the outside temperature or lower as described above, so the high-temperature areas are kept outside. It is designed so that the temperature does not rise much higher than the outside temperature at or below the ambient temperature. In addition, indoor air conditioning cools the air in the air flow passage 6 inside the partition wall 7, the space below the attic, and the air flow passage 6' to keep the outer peripheral space of the room at a relatively low temperature and keep the temperature of the room as low as possible. We are trying to maintain this.

Next, in the winter, the electric damper 16 and the switching valve 13 are closed and the air supply fan 12 is operated. The air in the area above the insulation walls 10, 10' of the attic space 5, which is higher than the outside air temperature due to solar heat, and the air in the underfloor space 4, which is slightly higher than the outside air due to geothermal heat, are transported by the air fan 12. It circulates through the flow path 6 and the air duct 14', and the roof sheathing board 9,
It absorbs solar heat through 9', making it higher than the outside temperature, and the indoor heating heat is absorbed by the room walls 3, 3'.
Even if heat is radiated outward from the room, the insulation partition wall 7, insulation walls 10, 10', and insulation material 8 prevent further heat radiation and heat radiation to the outdoors, keeping the ambient air outside the room as warm as possible. This increases the indoor heating effect.

These airflows not only provide heating and cooling, but also release moisture from the timber in the house, preventing moisture and condensation, and reducing pest damage and corrosion.

As described above, according to the present invention, the following effects can be obtained by having the above configuration.

(1) In the summer, hot air is released and the temperature is kept low without using any special heat or cold sources, and in the winter, solar heat, geothermal heat, and room heating heat are used to keep the temperature as warm as possible, (2 ) Forced air is used to eliminate temperature differences between the attic and under the floor, and between rooms on the south and north sides. and improve the durability of the entire house.
