Description

[Detailed explanation of the idea] The present invention relates to improvements in solar devices.

Conventionally used solar devices include natural circulation type and forced circulation type.

. As shown in Figures 1 and 2, the natural circulation solar device has a heat insulating material and a reflective plate 2 inside a shallow box-shaped case 1.
The upper header pipe 3 is placed on the upper surface of the case above the case, and the lower header pipe 4 is placed below the case in parallel to each other. A pair of heat collecting plates A and B are formed by placing heat collecting plates connected at right angles to each other, and placing a transparent plate 6 such as glass on top of the heat collecting plates, and placing the heat collecting plates A and B in parallel on the rooftop. Then, the upper header pipes 3, 3 are connected by a connecting pipe 3', and the lower header pipes 4, 4 are connected by a connecting pipe 4' to form a heat collecting board A.

A tea bath tank 7 is placed on the rooftop located above B, and water is sent to the lower header pipe 4 of one of the heat collection panels B by a water supply pipe 8 whose one end is connected to a water faucet or a water storage tank, and then connected to a connecting pipe. 4' to the lower header pipe 4 of the other heat collection panel A, and by water pressure, the hot water is transferred to the upper header pipes 3, 3 via the vertical pipe 5.5, and in the meantime, the hot water heated by solar heat is transferred to the tea water tank. 7 and is configured to supply hot water using a head difference through a hot water supply pipe 9 extending from the tea water tank 7 to each hot water supply location such as a bathroom or a kitchen.

Also forced circulation type? - The color device is as shown in Figure 3.
In the above-mentioned natural circulation system, only the pair of heat collection panels A and B are placed side by side on the rooftop and are positioned diagonally.The hot water storage tank 7 is placed on the ground, and the lower header pipe 4 of one heat collection panel A is and the lower part of the tea bath 7 are tied together with a cold water supply pipe ``!8'', and the connecting pipe 4' of the lower header pipe 4.4 is connected.
The lower header pipe 4 of the other heat collection board B is connected to the lower header pipe 4 of the other heat collection board B, and the upper header pipes 3, 3 are also connected by the connection pipe 3', and the upper header pipe 3 of the heat collection board B and the upper part of the tea bath tank 7 are connected. They are connected by a return pipe 11, and a temperature detection sensor S1 for the high temperature part is provided for the heat collection board, and a temperature detection sensor S2 for the low temperature part is provided in the hot water storage tank 7, and both sensors are connected by a connection line 10. be.

Therefore, at first, the heat collecting plates of heat collecting plates A and B are not filled with water.

When the tea bath tank 7 is filled with water, the temperature difference sensor S1. S2
The temperature difference between the high-temperature parts of the heat collecting panels A and B and the low-temperature part in the tea bath tank 7 is caught, and when the temperature difference becomes 5°C or more, the circulation pump P is activated and the water is sent to the cold water delivery pipe 8.
From there, pass through the lower header pipe 4 of heat collector A, the connecting pipe 4', push it up to the lower header pipe 4 of heat collector B, and then push the vertical pipes 5° 5.5... of heat collector boards A and B upward. During the transfer, it is heated by solar heat, and the tea water is transferred from the upper header pipe 3 to a return pipe 11 into a tea water tank 7, and is sent to each hot water supply location such as a bathroom, a kitchen, etc. through a hot water supply pipe 9.

Therefore, the former natural circulation solar device has heat collection board A,
Since B and the tea bath tank 7 can be installed very close to each other on the same roof, the amount of expensive circulation pipes used to connect them is extremely small, and a forced circulation device is not required, making it easier to use than a forced circulation type. Although it has the advantage that it can be installed at a very low cost, it takes a long time to obtain hot water, and the heat collecting plates that can be built into each heat collecting board A and H are located above and below in parallel. Since the header pipes 3 and 4 are connected by the vertical pipe 5 located at right angles thereto,
Although it is possible to keep the tea bath tank warm with heat insulating material, there is water remaining in the heat collecting board, but this combined with the fact that the heat collecting boards A and B sides cannot be covered with heat insulating material, has the disadvantage of being susceptible to freezing due to changes in temperature and weather. Ah □.

Although the forced circulation type solar device has the advantage of being able to obtain hot water in a short time, it requires a large installation space because the single hot water tank 7 is installed on the ground, making it difficult to install in houses where there is no installation space. It is impossible to install the heat collector panel A.
, The circulation pipe connecting B and the tea bath tongue must be long and extremely expensive, and it is similar to the heat collecting plates of heat collecting plates A and B or the heat collecting plates for natural circulation solar devices. Because of its structure, it has the same disadvantages as the natural circulation type, such as being susceptible to freezing due to changes in temperature and weather.
′: It was.

□The present invention has a structure in which a tea water tank is installed on the rooftop, facing upward, and close to the bottom of a pair of heat collection panels A and B.・
One end of the lower header pipe of each of the heat collecting plates is inclined downward, and the inclined lower part of the lower header pipe of one heat collecting plate is connected to the tea bath tank by a return pipe, and the lower header of the other heat collecting plate is connected to the tea bath tank. By connecting the lower part of the slope of the pipe and the tea bath tank with a water pipe, and by installing a forced circulation device such as a temperature difference sensor and a motor-equipped pump with an anti-idling pump, which are included in the conventional forced circulation method,
Like the conventional natural circulation system, it can be installed under any conditions (houses that do not have the installation area for a tea bath tank), and solar equipment can be provided at a price that is not much different from the above system. The method takes advantage of the natural circulation method and forced circulation method, which allow hot water to be obtained in a short period of time. It completely prevents freezing caused by changes in temperature and weather due to residual water, and not only can it always operate smoothly, but the pump and motor are easy to install and maintain, and the pump and motor have a long service life.

27b, reaches the lower header pipes 26a and 26b, flows to the inclined lower part of the lower header pipes 26a and 26b, enters the tea bath tank C from the return pipe 34 or the water supply pipe 37, and remains in the heat collecting plate 23ay 23b. It does not produce water.

However, when the pump P stops and the heated water descends from the upper header pipe 25a of the heat collection panel A, the automatic air vent 43 needs to send air from the upper header pipe 25a, the vertical pipe 27a, and the lower header pipe 26a. The air vent valve 43 does not necessarily need to be present, and air can be supplied from the return pipe 34 even without this air vent valve 43.

Due to the structure installed outside the tank, it can be installed under any conditions (houses that do not have an installation area for a hot water tank) in the same way as the conventional natural circulation method, and also provides a solar device at a price that is not much different from the above method. In addition, by taking advantage of the advantages of the natural circulation method and forced circulation method, which can obtain high temperature hot water in a short time like the forced circulation method, in both of the above methods,
Completely prevents freezing due to changes in temperature and weather due to residual water inside the heat collection board, which is impossible to solve.
This has the effect of providing a solar device that can always operate smoothly.

Furthermore, since the pump with motor is installed both inside and outside the tea water tank, installation and maintenance of the pump and motor are easy, the life of the pump and motor is long, and the use of solar equipment is durable. .
