Description

A multifunctional shutter type solar heat collector system

technical field

The invention relates to the technical field of solar thermal utilization and building energy saving, in particular to a solar heat collecting device of a thermal convection window and an automatic control system for photothermal conversion thereof.

Background technique

People's energy consumption is increasing day by day, and our country is also facing the danger of energy shortage. Among the energy consumption, the energy consumption generated by the construction and use of buildings accounts for 53.6% of the total global energy consumption, of which the heat loss of windows accounts for 40-50% of the energy loss of buildings. The heat exchange between the windows of the building and the outside world will lead to an increase in the energy consumption of the building.

The use of double glazing can reduce the building energy consumption caused by the heat exchange between the window and the outside world, and has a good sound insulation effect, which can improve living comfort. At present, office buildings and other public buildings mostly use large floor-to-ceiling windows, and curtains are generally not used for shading in public areas of buildings. Due to the large area of windows and no curtains, the building energy consumption is higher. Light pollution is common in high-rise office buildings, that is, the curtain walls of high-rise office buildings and other buildings will reflect sunlight to other places, resulting in light pollution. When there is no wind outside, it is difficult to open the windows to form air convection. At this time, the air circulation of large buildings relies on fans, which will increase the energy consumption of the building.

Solar heat collection has the advantages of energy saving, cleanliness, sustainable use, and wide distribution. However, traditional solar heat collection has uncontrollable photothermal conversion efficiency and fixed installation angle of the collection device, which cannot meet the optimal working conditions; when the light is too strong, Hot water is easy to boil in the heat collecting device, causing explosion hazard; solar heat collectors are generally located on the top floor of buildings, after snowfall, the heat collecting panels will not receive sunlight, causing the system to stop collecting heat; at the same time, solar water heaters also require additional Installation takes up extra space, is not easy to clean, and the heat collection efficiency is declining year by year.

Therefore, if a set of devices can be developed for the above problems, the energy consumption of buildings can be reduced, the light pollution of buildings can be reduced, and the comfort of buildings can be improved.

The sprocket drives its next sprocket to rotate through the chain in turn, so as to realize the shutter-type opening and closing of all heat collectors.

When in use, the water in the external water tank flows in from the water inlet under the action of the pump, flows out from the water outlet after passing through the serpentine copper pipe, and then flows into the external water tank again for circulation. When water needs to be released, open the water outlet to release water.

Preferably, the heat collecting sheet is a magnetic sputtering aluminum-based blue titanium coated heat collecting sheet, so as to further improve the heat collecting effect.

Preferably, the built-in heat transfer medium of the serpentine copper tube is a refrigerant.

Among them, the water inlet 1 and the water outlet 2 are installed side by side on the outside of the window frame 3, the bottom of the window frame 3 is made with a retractable water outlet 8, and the water outlet 8 is usually embedded inside the window frame 3, which is convenient for opening and closing. The window is opened by pulling the water discharge port 8 when water needs to be discharged in winter, and the window frame 3 is installed with a solar panel 5 and a rain sensor 7 on the side facing the outdoors;

The heat-insulating window frame 6 is fixed and used with the window frame 3 through the rotating shaft, and the electric push rod 4 is used to control the switch of the window. On the inner side of the window frame 3, the heat-insulating window frame 6 is installed with a heat-insulating double-layer glass 10 toward the indoor side, and a high-transparency single-layer glass 9 is installed toward the outdoor side;
