Description

[Detailed description of the invention] The present invention relates to heating and cooling of houses and the like.

Reflecting today's energy-saving era, various energy-saving heating and cooling systems have come to be used in homes.

However, there is no limit to the desire for comfort, and as people become accustomed to comfort, they end up using devices for long periods of time, which requires a lot of energy.

Therefore, in order to obtain a large heating and cooling effect with a small amount of energy, the idea of installing pipes underground and passing air through them for cooling in the summer and heating in the winter has been considered and is currently in the experimental process. However, since it uses a simple pipe, it is very long and requires digging a 5m to 10m hole under the floor of a small house and burying it.
In addition, it is difficult to bury it in places where the groundwater is shallow.

The present invention puts this into practical use with a short pipe.

Embodiments of the present invention will be described below based on the drawings.

There are a plurality of partitions H inside the cylinder, and between the partitions H, a heat storage and radiation tube 1 having a plurality of fins 2 is buried underground in a U-shape, one end of which is open to the underfloor space 9,
The other end is connected to the duct 3 and is electrically connected to the attic space 8, and a fan 4 is attached to the tip thereof.

The above is surrounded by an insulated outer wall 5, an insulated soffit 7, an insulated roof 6, and an insulated underfloor concrete 10, and the underfloor space 9 and the attic space 8 are surrounded by wall cavities 11, 12, 13. Conducted.

Let's take a look at how a building constructed in this way works.

In summer, the fan 4 is driven to suck air through the duct 3. Then, the air moves as follows.

The air of 23℃ in the underfloor space 9 is the ventilation layer S of the heat storage and radiation pipe 1.
At this time, the cylindrical part, partition H and fin 2
Heat exchange takes place on the surface of the ground, and the temperature becomes 18 degrees Celsius underground, which flows through the duct 3 and is discharged into the attic space 8.

The released cold air cools the inner walls while falling down the wall cavities 11, 12, and 13, becoming high temperature and flowing into the underfloor space 9.
Return to. This series of circulation provides coolness to the room.

In winter, the summer temperature is absorbed into the ground during the summer cycle, resulting in a temperature of 25°C.

In general, the underground temperature is about 15 to 20 degrees Celsius, so
10℃ is considered a high temperature.

In winter, if the average temperature indoors is 15°C, you will feel warm.

As in summer, the fan 4 is operating, and the cold air in the underfloor space 9 passes through the ventilation layer S of the heat storage and radiation pipe 1 and reaches 20°C.
The temperature rises up the duct 3 and enters the attic space 8.
At this time, it warms the inner walls and returns to the underfloor space 9, becoming colder. This series of air circulation provides warmth to the room.

Incidentally, the surface area of the heat storage/dissipation tube 1 is approximately six times that of a cylindrical tube. Since heat exchange by air is proportional to surface area, it can be seen that a large surface area does not require a large length.

Even if the fan 4 is stopped, the cold air in the underfloor space 9 flows down the ventilation layer S of the heat storage/dissipation tube 1 due to gravity, is warmed, and rises, producing a heating effect through natural circulation.

As described above, this is a geothermal heating and cooling system that contributes to energy savings by using summer's high temperatures in the winter and winter's low temperatures in the summer.
