Abstract

PURPOSE:To obtain large cooling and heating effects with small energy by laying under the ground a heat accumulating and radiating tube having a plurality of partitions on the inner side of a cylinder and a plurality of fins in a U-shape, introducing one end of the tube under the floor and another end into a space above the ceiling through a duct and providing a fan at the tip end of the tube. CONSTITUTION:In summer, when the fan 4 is driven and air is sucked up through the duct 3, air in a space 9 under the floor, having a temperature of 23 deg.C, for example, passes through a vent layer S of the heat accumulating and radiating tube 1. Upon this occasion, heat exchange is performed between the surfaces of the cylindrical part, partitions H and fins 2, and air assumes a temperature equivalent to the coolness of 18 deg.C, for example, and is discharged into the space 8 above the ceiling. Since the temperature under the ground is generally in the range of approximately 15-20 deg.C, cool air in a space 9 under the floor passes through a vent layer S of the heat accumulating and radiating tube 1 by driving the fan in winter similarly as in summer, and assumes a temperature of 20 deg.C, for example, the air rising up through the duct 3, being discharged into the space 8 above the ceiling, and falling down through wall cavities 11, 12 and 13.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to heating and cooling systems for houses, etc. Reflecting today's energy-saving era, various energy-saving heating and cooling systems have come to be used in houses.

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 achieve the effect of cooling and heating the dog with a small amount of energy, an idea has been developed and is currently in the experimental process of installing a pipe underground and passing air through it to cool the dog in the summer and heat it in the winter. However, since it uses a simple pipe, it requires a long length, and 9 holes of 5 m and ioms must be buried under the floor of a small house.In addition, it is difficult to bury the pipe in places where the groundwater is shallow. ing.

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 multiple partitions (■) inside the cylinder, and between the partitions H, a heat storage/dissipation tube (1) with multiple fins (2) is buried underground in a U-shape, one end of which is connected to the underfloor space (9). The other end is connected to a duct (3) for conduction to the attic space (8), and a fan (4) is installed at the tip.

The above are insulated external walls (5), insulated soffits (power), insulated roofs (6), insulated subfloor concrete I
The underfloor space (9) and attic space (8) are electrically connected through wall cavities (11), (12), and (13).

Let's take a look at how a building with such a shoddy structure works.

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

Air at 23°C in the underfloor space (9) passes through the ventilation layer S of the heat storage/dissipation tube (1), and at this time, the cylindrical part, the partition H, and the fin (2)
Heat is exchanged on the surface of the pipe, and the water flows through the underground duct (3), which is as cold as 18°C, and is discharged into the attic space (8).

The released cold air flows through the wall cavities (11), (1,2), 03
), the inner walls are cooled down and the temperature rises to a high temperature, which is the space under the floor (
Return to 5]). This series of circulation keeps the room cool.

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

Generally, the underground temperature is about 15 to 20C, so 5 to 10
℃ has become a high temperature.

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

As in the summer, the fan (/I) is running, and the cold air in the underfloor space (9) passes through the ventilation layer S of the heat storage/dissipation tube (1).
It rises up the duct (3) with a temperature of 0°C and is discharged into the attic space (8), and the wall cavities (1, 1), (], '2),
It descends from (13), and at this time it warms up the inner wall, which makes it cold and returns to the underfloor space (9). This series of air circulation creates warmth in the room.

By the way, the surface area of the heat storage and radiation tube (1) is about six times that of a cylindrical tube. Since heat exchange by air is proportional to the surface area, it can be seen that a large surface area or length is not required.

Even if the fan (4) is stopped, the cold air in the underfloor space (9) falls through the ventilation layer S of the heat storage and radiation pipe (1) due to gravity, is warmed, and rises, producing a heating effect through natural circulation. .

As described above, this is an underground thermal storage heating and cooling system that contributes to energy conservation by using summer's high temperatures in the winter and winter's low temperatures in the summer.
