Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a house that utilizes natural forces for heating and cooling, and is suitable for installation in areas where there is a large temperature difference between day and night.

(Conventional technology) In recent years, solar water heaters have been installed on rooftops to heat each room by passing hot water through them in the winter, and air from deep underground wells is guided indoors to provide heating and cooling. A so-called energy-saving heating and cooling system has been developed.

(Problem to be solved by the invention) However, using a water heater or air from a well hole requires a pump and a blower, and the equipment costs are high. Furthermore, in inland areas where there is a large difference in temperature between day and night, the cold air at night is intense, making it difficult to heat the house at night using hot water obtained from solar heat or warm air from wells.

(Means for solving the problem) In contrast, this idea is designed to solve problems in areas where there is a particularly large difference in temperature between day and night, such as desert areas in foreign countries, where the temperature can reach 50 degrees Celsius during the day and -10 degrees Celsius at night. It can be used in such places to achieve the greatest effect, and in addition to storing solar heat and using it for heating at night, it also stores cold air at night, which has not been used in the past, for daytime cooling. By using this system, heating and cooling during the day and night can be done most efficiently.

(Example of the invention) An example of the invention will be explained with reference to the drawings.
Figure 1 shows how it is used during the day, and Figure 2 shows how it is used at night.The building is divided into two rooms with a partition wall 1 in the middle, one room A is for night use; The other room B is used for daytime use. The roof 2, peripheral wall 3, and partition wall 1 that form each of these rooms are made of a solid insulating wall, for example, a double wall made of brickwork inside and outside, with a layer of polystyrene foam interposed between them, and this is made of concrete in advance. Cloth foundation 4
A rack is fixed on top. This cloth foundation 4 has concrete laid inside its enclosure frame, and is partitioned in the center to form two box-shaped sections corresponding to rooms A and B.
Inside each of these box-shaped compartments is a heat storage material such as sand 5.
a and 5b are fully filled.

The entire building is built so that Room A faces south, and Room A, facing south, has a fairly large door 6, and Room B, facing north, has a slightly smaller door 7. It is attached. Further, a partition door 8 made of a heat insulating material is attached to a passage provided in the partition wall 1 in the room. Incidentally, reference numerals 9... are ventilation holes opened in each room, and it goes without saying that they may not be provided in this part, but may be provided, for example, on the east and west walls.

(Effect of the invention) This invention has the above-mentioned structure, and in order to use it during the day, the door 6 of room A must be fully opened as shown in Figure 1, so that the heat storage material 5a inside is sufficiently heated by the sun. At the same time, the other opening/closing door 7 is kept closed.

Next, at night, the door 6 of room A is closed as shown in FIG. 2, and the door 7 of room B is opened so that the heat storage material 5b is cooled by the cold air at night. As a result, in room A in FIG. 2, the interior of the room is sufficiently heated through the heat storage material 5a heated during the day, so the occupants live there by placing an insulating rug 10 on top of the heat storage material 5a. Then, in the morning, A as shown in Figure 1.
The door 6 of the room is opened, the door 7 of room B is closed, and the rug 10 is spread on the heat storage material 5b which has been cooled at night.

As described above, this idea divides the building into rooms A and B, and the floor of each room is formed on the top surface of each heat storage material 5a, 5b, and the living room is moved between rooms A and B every morning and night. By doing so, you can spend your days and nights comfortably.

Note that if the inner surface of the opening/closing door 6 of the room A is made to be a reflective surface, the heat storage material 5a will be heated to a higher temperature due to the reflection. Note that 11 is a solar water heater.

Moreover, although normal sand is used for the heat storage materials 5a and 5b, in this case, if silica sand or sand mixed with iron sand is used, the heat storage performance is further improved.

As mentioned above, this idea uses sand as a heat storage material, which has excellent heat storage properties and can be easily filled depending on the installation location, does not require power, and is inexpensive to construct. There are many advantages that can be achieved.

Claims (1)

[Scope of utility model registration request] An insulating sealed building is erected on the cloth foundation, and the inside of the cloth foundation is formed into a pair of box-shaped compartments on the left and right, each of which is covered with heat storage material such as sand, and the building is also placed on the cloth foundation. This is an air-conditioned house that takes advantage of the temperature difference between day and night.The interior is divided into two rooms on the left and right, and each room is equipped with a door that opens and closes, one for sunlight intake and the other for nighttime cold air intake. .
