Abstract

PURPOSE:To obtain enough space heating effect by covering the top surface of concrete laid on the ground with a water-proof sheet, on the tip of which heat-insulating material is laid without a gap, and placing slit pipes among pebbles on the top surface of a concrete layer having hollow pipes therein. CONSTITUTION:The top surface of concrete 23 laid on the ground is covered with a water-proof sheet 24, on top of which heat-insulating material 25 is laid without a gap, and hollow pipes 26 are disposed and fixed in place on the top surface of the heat-insulating material 25. Warm air generated by waste heat of living or solar heat exists in the garret 15, and cool air under the floor 9. When an intermediate fan 17 is operated to selectively draw the hot air in the upper part of the garret 15 from a slit 19 in slit pipes 20, the hot air is forced through a check valve 16 to descend through a duct 14 and is uniformly blown to the entire space 9 under the floor out of a slit 12 of slit pipes 12 through a duct 7. The space heating is performed in this manner. The heating effect is enhanced by heating water inside hollow pipes 26 buried in a concrete bed 27 in which heat is stored during the daytime, and retrieving the heat at night by operating an intermediate fan 8.

Description

[Detailed description of the invention] [Industrial application field] This invention relates to heating and cooling of houses.

[Conventional technology]

Traditionally, ventilation and cooling in buildings was achieved by mechanically exhausting air through vents under the floor, or by mechanically removing hot air from the attic space, but neither of these methods was able to provide sufficient coolness.

This is because the cold source of the subfloor surface cannot be used, and the problem with conventional methods is that it is not possible to create cold air by bringing outside air into contact with the cold source of the subfloor surface.

In addition, in heating, it is known that the exhaust air from inside the building collects in the attic space and cold air accumulates in the underfloor space, but under natural circumstances, warm air from the attic space cannot be guided to the underfloor space. There is also a method of using a ventilation fan to blow air from the attic space through a duct, but this method has the disadvantage of not being able to provide a sufficient heating effect because the air cannot be evenly distributed to the underfloor space.

Furthermore, one of the problems that must be overcome is the low amount of heat storage, which is a common problem in both heating and cooling systems.

[Problem that the invention seeks to solve]

Therefore, in order to eliminate the drawbacks of the prior art, the present invention aims to create cold air by bringing outside air into contact with the subfloor surface, increase the amount of heat storage by stone and concrete layers, and move air all over the underfloor area for air conditioning and heating with a small amount of energy. The purpose is to

[Failure to solve the problem]

The present invention will be explained below based on the drawings.

FIG. 1 is an explanatory diagram showing the operation of the present invention. An underfloor ventilation opening 1 has a check valve 2, a damper 4 is opened and closed by an opening/closing screw 3, and a tapered duct 5 is connected to the underfloor ventilation opening 1. An intermediate ventilation fan 8 is provided between the duct connection port 6 and the duct 7, and the duct 7 is connected to a number of cylindrical slit pipes 12 having partitions 10 and slits 11 arranged on the ground in the underfloor space 9. A cap 13 is fitted to the end of the slit pipe 12, and a duct 14 is connected from the attic space 15 to the duct 7, with a check valve 16 and an intermediate ventilation fan 17 in the middle, and a cylindrical pipe at the tip. A slit pipe 20 with a partition 18 and a slit 19 is connected to the slit pipe 20, and a cap 13 is fitted to the end thereof. In a retractable house, concrete 23 is poured on the ground, a waterproof sheet 24 is stretched over the top of the concrete 23, a heat insulating material 25 is laid on top of the waterproof sheet without any gaps, and the top of the heat insulating material 25 is The hollow pipe 26 is arranged and fixed to form a circulation path as shown in FIGS. 4(a) and 4(b), and the hollow pipe 26 is buried in a concrete layer 27. A large number of slit pipes 1 are arranged on the upper surface of 27.
This is a house with a mixture of stone 2 and stone 28.

[For production]

Next, the operation will be explained with reference to FIG.

The cross-sectional area of the slit pipe 12 is made smaller than that of the duct 7, and the opening of the slit 11 is made smaller to drive the intermediate ventilation fan 8. The pressure is distributed evenly to all the slits 11, and the air is evenly distributed over the entire surface of the underfloor space 9.

In other words, this is the same principle as when blowing air into the cloth bag of a futon dryer, the air is blown out evenly over the entire area through small gaps in the cloth. Furthermore, the concrete layer 27 is filled with water, liquid such as antifreeze, or air in the buried hollow pipe 26.
Other gases are heated or cooled and circulated by a boiler or cooling tower, and together with the stones 28 present on the upper surface of the concrete layer 27, the heat storage effect is further enhanced.

(Example〕 The case of summer will be explained with reference to FIG.

In summer, the damper 4 of the underfloor ventilation opening 1 is opened by the opening/closing screw 3, and the attic ventilation opening 22 is also opened.

When the intermediate ventilation fan 8 is driven, the check valve 2 is opened from the underfloor ventilation opening 1.
As shown in FIG. 3(a), the outside air passes through the duct 7, applies pressure to the slit pipe 12, is transmitted to the camp 13 at the end, and is evenly distributed to the slit pipe 11 and blown out into the underfloor space 9. The cold air mixed with the cold air near the ground applies pressure to the underfloor space 9, and since the check valve 2 prevents the cold air from flowing out in the underfloor ventilation opening 1 where there is no intermediate ventilation fan 8, that pressure is applied to the wall cavity. 21 to push up the hot air in the attic space 15 and release it to the outside through the attic ventilation opening 22.

On the other hand, pressure is applied in the duct 14 and reaches the check valve 16, but the check valve 16 prevents the air from moving.

A cooling effect can be obtained by operating the intermediate ventilation fan 8 during hot days and cool nights. In addition, the water in the hollow pipe 26 buried in the concrete layer 27 is cooled at night, the cold heat is stored in the concrete layer 27, and the cold heat is extracted by operating the intermediate ventilation fan 8 during high temperatures during the day.
A cooling effect can be obtained throughout the building.

Next, the case of winter will be explained with reference to FIG. Underfloor ventilation port 1
The damper 4 is closed by the opening/closing screw 3, and the attic ventilation opening 22 is also closed.

In winter, warm air accumulates in the attic space 15 due to household waste heat and solar heat, and cold air collects in the underfloor space 9, thereby cooling the room.

The warm air that has gathered in the attic space 15 will not naturally flow down to the underfloor space 9, and that heat will be of no use as it is.

Therefore, if the intermediate ventilation fan 17 is operated, the attic space 15
The high-temperature air at the top of the slit pipe 20 is selectively sucked in through the slit 19 of the slit pipe 20 as shown in Fig. 11 and uniformly over the entire surface of the underfloor space 9.

In this way, warm air is selectively forced into the underfloor space 9 for heating. Also, contrary to the case of summer, concrete layer 2
The water in the hollow pipe 26 buried in the pipe 7 is heated during the day, the heat is stored in the concrete layer 27, and the intermediate ventilation fan 8 is heated at night.
It operates to extract heat and increase the heating effect.

Further, the heat storage structure according to the present invention can be used not only in air cycle houses but also in frame structures, 2×4 structures, and prefabricated structures. Furthermore, it is also possible to have a structure that does not use the slit pipe 12, 20, the cap 13, or the stone 28.

〔Effect of the invention〕

As explained above, according to the present invention, the subfloor surface has a heat storage structure, which contributes to energy saving by utilizing cold heat, waste heat, forced heating and forced cooling, and also strengthens the earthen floor and foundation. It has the characteristics of improving heat insulation, insect repellency, mold resistance, sound insulation, corrosion resistance, and vibration resistance.
