Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an air circulation method in buildings, and particularly to an air circulation method that allows ventilation in the summer and snow melting in the winter.

[Related technologies and their problems]

A roof is constructed using beams, purlins, and oak wood on the exterior walls with ceiling panels. Roofing materials are installed on the top of the oak wood, and a ventilation system with exhaust ports on both sides is installed in the roof ridge. Also known is Japanese Patent Publication No. 59-43624, in which a reflective plate is provided on the lower surface of the roof and a ventilation path is formed between the roof material and the reflective plate. However, while this can prevent condensation on the roof, it has the inconvenience of not being applicable to melting snow on the roof or preventing condensation on the wall.

[Purpose of the invention]

An object of the present invention is to provide an air circulation method for buildings that can melt snow on roofs and prevent condensation on roofs and walls.

[Summary of the invention]

The air circulation method for buildings of the present invention involves introducing outside air into the building through hollow passages in the walls and into the attic, then flowing out to the outside through numerous vents on the roof surface to prevent condensation. The heated air flows out from the vent to melt snow.

〔Example〕

As shown in FIG. 1, warm air 3 generated by a heating device (not shown) in 10 rooms 2 of the building is introduced into the attic 6 through the opening 5 of the ceiling 4, and then the warm air 3 is distributed over almost the entire roof surface 8 at numerous intervals. The heated airflow 3a is blown out to the outside from a warm air vent lower which is opened, and the ejected warm airflow 3a covers the roof surface 8, and the snow on the roof surface 8 is melted by this warm airflow 3a. Fig. 1 shows a corrugated roof surface 8, and a ventilation lower is formed on the sloped part from the peak to the valley, but the ventilation lower can be applied to the root surface of various structures, For example, a ventilation lower extending diagonally downward may be formed at the boundary of the slanted roof surface. Therefore, almost the entire roof surface 8 is constantly warmed by the circulation action of the warm air current 3a, and accumulated snow is easily melted, and even during heavy snowfall, it gradually melts from the point where the warm air current 3a ejects, forming a cavity, and the snow melts. The snow is melted entirely by the energy of the water, and the amount of snow can be maintained at all times without the need for snow removal work, and since the roof surface 8 functions as a ventilator, dew condensation in the attic 6 is effectively prevented. In the summer, as shown by the dashed line, the underfloor ventilation holes 9 and 10 pass through the hollow passage 12 of the wall 11 into the attic 6, and the roof surface 8
The air is emitted from almost the entire area to provide ventilation and prevent condensation on walls and attics. In this case, since the ventilation lower is formed downward from the horizontal direction, snowmelt water does not flow in from the ventilation lower. It is preferable that the vent hole is formed in the form of a hot air flow passage by a double structure.

Figures 2 and 3 show a case where a ventilation fan 13 or a heat exchanger, etc. is installed, and in winter, outside air is introduced from the ventilation fan 13 or heat exchanger, etc. in the upper part of the room 2, and is heated by the heating device inside the room 2. The warm air 3 passes through the hollow passage 12 and is guided to the attic 6, and is blown out from the ventilation lower to melt the snow. The air is guided from the upper part of the room 2 through the hollow passage 12 to the attic 6, and is blown out from the ventilation lower to provide ventilation.

Fig. 4 shows the case where the well 14 is used as a thermal energy source.In the winter, when the heat of the well 14 is circulated by the dehumidifying fan 15, warm air 3 flows as shown by the arrow, performing heating and snow melting functions, and even in the summer. By opening ventilation holes under the floor, windows, etc., cool air will circulate.

〔Effect of the invention〕

The air circulation method for buildings of the present invention is to introduce outside air into the building through hollow passages in the walls and into the attic, and then flow out to the outside through a number of vents in the roof to prevent condensation and introduce it into the attic. Warm air flows out through the vents to melt snow, which is highly effective as it melts snow in the winter, allows ventilation in the summer, and prevents condensation on the roof and walls.
