Description

[Detailed Description of the Invention] [Technical Field] The present invention heats the attic by installing a heat collector of a heat medium type solar heat collector on the roof and opening a conduit leading to the attic below the heat collector. The present invention relates to a roof for collecting solar heat that can efficiently utilize the collected air.

[Background technology]

The air in the attic is heated by solar radiation and heat transfer from the room, and according to the inventor's measurements, it is 20°C higher than the outside temperature in winter and 30°C in summer, and is ventilated 7 times per hour. Therefore, even though it has a heat amount that can be used as a heat source, it is released into the outside air through ventilation holes, ventilation holes, etc. without being used.

[Purpose of the invention]

The present invention is a solar heat collector that can utilize the heated air in the attic by attaching the collector to a support frame provided on the roof and opening the other end of the conduit leading to the attic below the collector. The purpose is to provide roofs for

[Disclosure of the invention]

An embodiment of the present invention will be described below based on the drawings. In the figure, a roof 1 for collecting solar heat has a heat collector 5 of a heat medium type solar heat collector 4 attached to a support frame 3 that stands up on a roof 2, and a heat collector 5 of a heat transfer medium type solar heat collector 4 attached to the roof 2, and a conduit 7 with one end leading to an attic 6 to collect heat. It opens below the container 5.

In this embodiment, the support frame 3 is a frame body comprising a front wall 11 and a rear wall 12 that stand parallel to each other with the ridge 10 of the roof 2 in between, and side walls 14, 14 that straddle the ridge 10 are provided on both sides of the front wall 11 and rear wall 12. At the lower ends of the wall portion 11 and the rear wall 12, there are provided leg portions 15 that face inward and are bent sharply at an angle along the slope of the roof 2.
5 is fixed to the roof board 16 via a waterproof sheet, and drain ports 19 are provided at the lower ends of the front wall 11 and rear wall 12 to drain rainwater accumulated in the support frame 3.
will be provided. Further, the upper edges of the front wall 11 and the rear wall 12, and flanges 17, 17 extending downward and inward are provided to face each other.

The heat collector 5 is spanned between the flanges 17, 17, and the heat collector 5 is arranged near the top 8 of the support frame, so that the heat collector 5 faces the outside air and can receive solar heat. .

The heat collector 5 has fins 20 arranged in parallel and in multiple rows, and passes through a tube 21 in a meandering manner. , heats the gas. Further, in this embodiment, a cover 23 is provided above the support frame 3, and the cover 23 has a rectangular hole in the upper surface through which the fins 20 can be opened.

The conduit 7 penetrates the roof 2 from inside the support frame 3, and one end leads to the attic 6, while the other end opens below the heat collector 5 and is connected above the opening 24 through the support frame. By providing an umbrella to cover the opening 24, rainwater can be prevented from entering the opening 24. Note that the conduit 7 may be bent into a U-shape so that the opening faces downward.

The heat collector 5 constitutes the heat medium type solar heat collecting device 4 as described above. The heat medium type solar heat collector 4 is
It consists of a heat storage tank 25, a heat exchange unit 26, and the heat collector 5, and the heat exchange unit 26 includes:
Pump 27, high pressure switch 29, and heat exchanger 30
, a compressor 31, an accumulator 32, and a dryer 33 are housed, and the latent heat contained in the air flowing in from the attic 6 and the radiant heat when the sun is irradiated are transferred to a heat medium such as Freon. The water is sucked up by the compressor 31, pressurized and heated by the compressor 31, heated by the heat exchanger 30, and then transferred to the heat storage tank 25.
The solar heat collector 5 is formed as a so-called latent heat absorption solar heat collection device for hot water supply that can store hot water in the attic. 5 forms a heat exchanger in the heat medium type solar heat collector 4 that receives external heat such as air or solar heat and transfers it to a heat medium to exchange heat with the external heat. Further, a heat collection sensor 35 and an expansion valve 36 are attached to the heat collector 5.

However, in the solar heat collecting roof 1 of the present invention, one end of the conduit 7 leading to the attic 6 is opened below the heat collector 5, and therefore the roof 2 is heated by the radiant heat of the sun. , and the air in the attic that has become high temperature as the heat generated in the room R is conducted through the ceiling board 22 is exchanged with the heat collector 5 through the conduit 7, and the heat exchanged air is released into the atmosphere.

〔Effect of the invention〕

In this way, the roof for collecting solar heat of the present invention has a heat collector attached to the support frame that stands up on the roof, and one end of the conduit that leads to the attic is opened below the heat collector, so that the outside air can be removed. In comparison, the heated air in the attic is 20℃ hotter in winter and 30℃ hotter in summer, and is ventilated seven times per hour.As a result, the heated air in the attic can efficiently exchange heat with the heat collector, making it possible to ventilate the attic. Not only that, the heat generated in the attic can be used effectively, saving energy, and the air can float naturally due to heating, allowing heat exchange with the collector, and by using a heat carrier type solar collector. This can bring about excellent effects such as increasing heat exchange efficiency.

In addition, in the solar heat collecting roof of the present invention, as long as the conduit is opened below the heat collector, the support frame may be provided at an inclined part such as the eaves of the roof, and various embodiments may be used. Can be transformed.
