Description

A multifunctional louvered solar heat collection system

technical field

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

Background technique

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

The use of double-layer glass can reduce the building energy consumption caused by the heat exchange between windows and the outside world, and the sound insulation effect is good, which can improve living comfort. At present, public buildings such as office 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 energy consumption of buildings is higher. Light pollution is common in high-rise office buildings, that is, building curtain walls such as high-rise office buildings will reflect sunlight to other places, resulting in light pollution. When there is no wind outside, it is difficult to form air convection with open windows. At this time, the air circulation of large buildings depends on fans, which will increase the energy consumption of buildings.

Solar heat collection has the advantages of energy saving, cleanness, 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 collection device, causing explosion hazard; solar heat collectors are generally located on the top floor of the building, and after snowfall, the heat collection plate will not receive sunlight and the system will stop heat collection; 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 device can be developed to address the above problems, the energy consumption of the building can be reduced, the light pollution of the building can be reduced, and the comfort of the building can be improved.

The sprocket 13 of one position rotates, and the other sprockets 13 drive the sprocket 13 of the next position through the chain 12 to rotate, thereby realizing the shutter-like opening and closing of all heat collecting fins 14.

During use, the water in the external water tank flows in from the water inlet 1 under the action of the water pump, flows out from the water outlet 2 after passing through the serpentine copper pipe 15, and then flows into the external water tank again for circulation. When needing to discharge water, open water outlet 8 and discharge water.

Preferably, the heat collecting sheet 14 is a magnetically sputtered aluminum-based blue titanium coating heat collecting sheet, so as to further improve the heat collecting effect.

Wherein, the water inlet 1 and the water outlet 2 are installed side by side on the outside of the window frame 3, and the bottom of the window frame 3 is shaped on a retractable water outlet 8, and the water outlet 8 is embedded in the inside of the window frame 3 at ordinary times, which is convenient for opening and closing. The window is opened by pulling the water outlet 8 when water needs to be released in winter, and the window frame 3 is equipped with a solar panel 5 and a rain sensor 7 on the outdoor side;

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

The heat collecting fins 14 are welded together with the corresponding serpentine copper pipes 15, and several sets of shutters are embedded between the two pieces of glass on the inner side of the heat insulating window frame 6, that is, the high light transmission single layer glass 9 and the heat insulating double layer glass 10. The heat sheet 14 and its corresponding serpentine copper tube 15, one end of the serpentine copper tube 15 is installed on one side of the inner wall of the heat insulating window frame 6 through the corresponding sprocket 13 and the rotating interface 16, and the other end is installed on the inner wall of the heat insulating window frame 6.

Motor 11 is installed on the inside upper end of described heat-insulating window frame 6, and sprocket wheel 13 is installed on the rotating shaft of described motor 11, and described motor 11 drives chain 12 to drive next by driving sprocket wheel 13 that is installed on its rotating shaft. The sprocket 13 of one position rotates, and the other sprockets 13 drive the sprocket 13 of the next position through the chain 12 to rotate, thereby realizing the shutter-like opening and closing of all heat collecting fins 14.

In this example, the heat collector 14 is a magnetically sputtered aluminum-based blue titanium coating heat collector, thereby further improving the heat collection effect; the built-in heat transfer medium of the serpentine copper tube 15 is a refrigerant; the rain sensor 7 The signal is transmitted to the electric push rod 4 to control the opening and closing of the window, so as to realize the automatic control of the electric push rod 4 to control the window closing according to the weather conditions; the solar panel 5 is externally connected to a battery pack to store electric energy and provide electric energy for the system to operate independently after de-energization.

When in use, the water in the water tank is pressurized by the water pump to pass into the heat medium water from the water inlet 1, flows through the serpentine copper pipe 15 connected in series, the rotary interface 16, and finally enters the water tank from the water outlet 2, and the serpentine copper pipe 15 and Magnetic sputtering aluminum-based blue titanium heat collector plates 14 are welded together to form a heat collection system; solar panels 5, electric push rods 4, and rain sensors 7 are installed on the outside of the heat-insulating window frame 6, and the inside of the heat-insulating window frame 6 A motor 11, a sprocket 13 and a chain 12 are installed, which jointly constitute the transmission system of the device, which can adjust the working area, control the opening and closing angle of the window and provide electric energy for the system; heat-insulating window frame 6, single-layer high light-transmitting glass 9.

When the window is open for ventilation, the electric push rod 4 opens the system to a suitable angle for ventilation. At this time, there is a large temperature difference on both sides of the window system, which will also generate a pressure difference, thereby achieving the effect of air heat convection. At this time Heat collection can also be carried out at the same time, only need to drive the magnetic sputtering aluminum-based blue titanium heat collection plate 14 through the motor 11 to adjust the angle according to the specific weather conditions, so as to collect heat; when it rains outdoors, the electric push rod 4 shuts down the system.
