Description

[Detailed Description of the Invention] This i&beak relates to a method for removing snow on Mll using #heat for indoor heating, and thereby removes snow that involves the danger and labor of removing snow. The purpose is to eliminate the need for work and prevent damage and collapse of roofs and houses.

In areas with a lot of snow, there is a lot of damage caused by the accumulated load on roofs, and to prevent this, it is necessary to carry out repeated work to remove the roof. However, this work requires a lot of effort and effort, as it involves a lot of risk.

On the other hand, in such snowy regions, indoor heating is usually carried out all day long, day and night.

The inventor of the present invention has studied a method of removing snow by shattering a large amount of snow on 1iIIL by making full use of the waste heat in this warm place as a heat source, and as a result, arrived at this development Ej4. It is something.

Hereinafter, the present invention will be explained based on the accompanying drawings showing one embodiment thereof.

Wholesale, this invention leads the combustion exhaust pipe 4 of the heater 8 installed in the same wall 2 having a roof l to a heating fluid exchange heat storage tank (hereinafter simply referred to as a heat storage tank) 5, and heats it with the heat storage tank 5. The heated fluid is guided through a thermally insulated heating fluid transfer pipe (hereinafter referred to as transfer pipe) 6 to a heat dissipation pipe 7 disposed on the roof l.

The low-temperature water that has passed through the heat dissipation pipe 7 is made to flow through an insulated reflux pipe 8 in an amount of 5Kml in an 11 isl tank, and is reheated and transferred to a transfer pipe 6.
It circulates to

For this circulation, a pressurizing device 9 such as a pump is used.

In addition, the heat dissipation pipe 7 installed on the roof hK is fixed to the transfer pipe 6 and the return pipe 8 by appropriately setting the piping density, piping method, etc., depending on the shape and size of the roof, such as in series, parallel, or a combination of both. do it. Polyethylene, polybutene, or metal pipes with less 1111 loss are used as such heat dissipation pipes, but in order to further prevent heat loss, these pipes may be coated with a moisturizing material.

In this case, as a contact point with a metal mesh or thin metal plate with good thermal conductivity installed on the top surface of the pipe or downward, it is sufficient to cut off a portion of the moisturizing material at various places so that the metal mesh, etc. comes into direct contact with the pipe. .

Exhaust heat from heating (usually 150-200℃)
The heated fluid is circulated under pressure 1l19 and melts the snow through the heat radiation pipe 7 on the roof. Since the melted water retains a certain amount of heat, it flows down onto the roof, expanding the area of the lightning strike.

Also, because of this retained heat, the snow does not become icicles when it flows down, and the snow can be melted and removed using the indoor exhaust heat without requiring any effort.

Furthermore, the snow on KJ14i is evenly removed by leveling the snow.
t9 is a metal mesh made of aluminum, copper, iron, etc. that has good thermal conductivity and is in contact with the lower surface of the roof. All you have to do is send it to

In this way, the heat for melting the snow is diffused over the entire roof surface by the metal mesh 10, so that the snow is thawed evenly and quickly over the entire surface, and it is also possible to arrange the heat dissipation pipes 7 sparsely. The cost required for installing the heat dissipation pipes 7 can also be reduced.

In addition, various known heat storage tanks can be used as the heat storage tank, but a sealed circulation path is formed through the transfer pipe 6, heat radiation pipe 7, reflux pipe & Fi heat storage tank 5, as shown in Fig. 4. A suitable liquid a is heated and evaporated by the exhaust heat of the heater 8.
is used as a heating fluid, and steam generated in the heat storage tank 6 is transferred from the pipe 6 to the heat radiation pipe. You can send it to '.

By doing so, the steam exchanges heat with *p-* or external air, is cooled in the heat radiation pipe 7, and is reduced to a liquid aI, and the pressure in this part is kept low, so that it is generated in the heat storage tank s. The heat-retaining steam automatically flows up to the top of the roof 1 due to the pressure difference, and
11 The condensed liquid is flowed into the heat storage tank due to the head difference, and a heat pipe type circulation path is used, which allows extremely efficient transfer and circulation of heat, and has high thermal efficiency. Since the pressure device 9 can be omitted, the equipment cost of the pressure device and the cost required for its operation can be reduced.

It should be noted that lit; is an injection port for liquid a, and 12Fi is an extraction port, and when the amount of fluid a as a heating fluid reaches 100 or decreases due to evaporation, it is replenished from this injection port. Antifreeze and other liquids are used as the liquid.

Note that this invention is not limited to the above-mentioned embodiments, and it goes without saying that the heat radiation pipes and other piping can be freely changed, and the type and arrangement of the heat storage tank can be adapted to suit the purpose of the invention. Changes can be made freely within the scope.
