[0034] To address the problem of snow accumulation or icing on solar panels in existing solar air conditioning systems, this application provides a solar air conditioning system that utilizes hot water produced by the air conditioner's built-in hot water function to melt snow or ice on the solar panels, eliminating the need for additional snow removal equipment and reducing overall costs.

[0035] Figures 1 to 3 A solar-powered air conditioning system provided in this application includes an air conditioner, a solar power generation device 3, and a snow melting device 4. The air conditioner includes an air conditioning body 1 and a water tank 2. The air conditioning body 1 is connected to the water tank 2 to heat the water in the water tank 2. The air conditioning body 1 can produce hot water and store the produced hot water in the water tank 2. The solar power generation device 3 is connected to the air conditioning body 1 to provide electrical energy to the air conditioning body 1. The solar power generation device 3 has a solar panel 31. The snow melting device 4 is disposed on the solar panel 31. The water tank 2 is connected to the snow melting device 4 to deliver hot water to the snow melting device 4.

[0036] It is understandable that by installing the snow melting device 4 on the solar panel 31, when there is snow or ice on the solar panel 31, the water in the water tank 2 is heated by the air conditioner body 1 and then transported to the snow melting device 4. As the hot water flows in the snow melting device 4, it can conduct heat to the solar panel 31, thereby achieving the purpose of melting snow and ice. This application utilizes the hot water production function of the air conditioner to provide hot water for the snow melting device to achieve the purpose of de-icing the solar panel, which can reduce the overall cost of the equipment.

[0037] In this embodiment, the air conditioner body 1 or air conditioner is a tri-generation air conditioner, including cooling, heating, and hot water supply functions, which can meet the needs of air conditioning, underfloor heating, and domestic hot water supply. Specifically, it can meet the needs of air conditioning cooling in summer, heating control in winter, and providing domestic hot water all year round. This application does not improve the specific structure of the air conditioner body 1, but uses the hot water supply function of the tri-generation air conditioner to deliver the hot water to the snow melting device 4 to melt the snow or ice on the solar panel 31.

[0038] refer to Figure 1 The hot water supplied by the domestic hot water module of the three-generation air conditioning system can be delivered to water-using devices (such as shower heads, faucets, etc.) connected to the domestic water interface 23 for user needs. This application sets up a branch line on the hot water supply pipeline of the domestic hot water module of the three-generation air conditioning system to introduce a portion of the hot water into the snow melting device 4.

[0039] In this embodiment, the entire solar-powered air conditioning system utilizes the circulating water pump and snow-melting device of the air conditioner's domestic hot water supply to directly obtain hot water from the domestic hot water tank of the air conditioning heat pump system for snow melting on the solar panels. The solar panels provide electricity to the air conditioning system, and the domestic hot water from the air conditioning system provides snow-melting hot water for the photovoltaic panels, thus integrating the solar panel snow-melting system with the air conditioning heat pump system, eliminating the need for a separate snow-melting system for the solar panels.

[0040] In some embodiments, such as Figure 2 As shown, the snow melting device 4 is located on the back side of the solar panel 31; by placing the snow melting device 4 on the back side of the solar panel 31, it can be ensured that the light-receiving area of ​​the light-receiving side of the solar panel 31 is not affected.

[0041] like Figure 3 As shown, in some embodiments, the snow melting device 4 includes a serpentine pipe 41, which includes multiple first pipe segments 411 and multiple second pipe segments 412. The multiple first pipe segments 411 are arranged sequentially from top to bottom and spaced apart along the backlight side of the solar power generation device 3. The multiple first pipe segments 411 are connected end to end through the second pipe segments 412 to achieve overall conductivity of the serpentine pipe. It can be understood that using a serpentine pipe allows for the laying of longer pipes on the backlight side of the solar panel 31 to extend the flow path of hot water, increase the contact area between the solar panel 31 and the serpentine pipe, and improve the snow and ice removal effect.

[0042] like Figure 3 As shown, in some embodiments, the water inlet 4a of the snow melting device is connected to the water tank 2; and the height of the water inlet 4a of the snow melting device is lower than the height of the water outlet 4b of the snow melting device.

[0043] It is understandable that the heat of the hot water in the snow melting device 4 will be gradually lost during the flow process, and the temperature of the hot water will gradually decrease. In this application, the height of the water inlet 4a of the snow melting device is lower than the height of the water outlet 4b of the snow melting device. As a result, the part of the solar panel 31 that is closer to the ground absorbs more heat from the hot water. The ice and snow on the solar panel 31 that is closer to the ground will melt faster and slide down. The ice and snow at the top, without support, are more likely to form an avalanche effect and fall off, thus improving the snow and ice removal effect and efficiency.

[0044] For example, refer to Figure 3 Multiple first pipe sections 411 are arranged in parallel. The end of the uppermost first pipe section 411 that is not connected to the second pipe section 412 is the water outlet 4b of the snow melting device; the end of the lowermost first pipe section 411 that is not connected to the second pipe section 412 is the water inlet 4a of the snow melting device.

[0045] In this configuration, multiple first pipe segments 411 are arranged in parallel and spaced intervals from top to bottom along the backlight side of the solar panel 31. As a result, during the snow and ice removal process, the temperature of the solar panel 31 increases from top to bottom, creating a temperature gradient difference on the solar panel 31. Under the action of thermal stress, the snow and ice are more likely to break in the direction perpendicular to the temperature gradient (i.e., the horizontal direction). After breaking, the lower part of the snow and ice is also warmer and is more likely to detach from the solar panel 31 and slide down. Meanwhile, the upper part of the snow and ice, without support, is more likely to form an avalanche effect and fall off, thus improving the snow and ice removal effect and efficiency.

[0046] In other embodiments, Figure 3 The location shown as the water outlet 4b of the snow melting device described above can also be the water inlet of the snow melting device. Figure 3 The position shown as the water inlet 4a of the snow melting device can also be the water outlet of the snow melting device.

[0047] In some embodiments, a snow accumulation monitoring sensor and a switching valve are also included. The snow accumulation monitoring sensor is used to monitor whether there is snow or ice on the sun-receiving surface of the solar panel 31. The switching valve is located on the connecting pipeline between the snow melting device 4 and the water tank 2, and the switching valve is electrically connected to the snow accumulation monitoring sensor.

[0048] Understandably, the condition of the solar panel 31's light-receiving surface is monitored by a snow monitoring sensor. When snow or ice is detected on the light-receiving surface of the solar panel 31, the switch valve is opened, and the water supply from the heating water tank 22 of the air conditioner body 1 is controlled to the snow melting device 4.

[0049] In some embodiments, the snow accumulation monitoring sensor can be a snow depth sensor, a specialized device that measures snow thickness in the natural environment using ultrasonic technology. This sensor employs an integrated capacitive electrostatic transducer probe design, featuring high sensitivity, strong anti-interference capability, and high accuracy. Specifically, this snow accumulation detection sensor can be positioned on the front of the solar panel. Alternatively, a road condition sensor can be used, its core being optical remote sensing technology. The road condition sensor emits a beam of light of a specific wavelength (such as infrared or laser) onto the light-receiving surface of the solar panel 31. By capturing changes in the spectral characteristics of the reflected light, it accurately identifies the differences in the molecular structure of substances such as water, ice, and snow. For example, the light absorption rate of a water film is significantly different from that of ice crystals; the sensor uses this to calculate water thickness, ice content, and even freezing point temperature. Specifically, this snow accumulation detection sensor can be mounted on one side of the solar panel using a bracket.

[0050] like Figure 1 As shown, in some embodiments, the air conditioner body 1 includes an outdoor heat pump unit 11 and an indoor unit 12 connected to the outdoor heat pump unit 11. The solar power generation device 3 is connected to the outdoor heat pump unit 11, and the water tank 2 is connected to the outdoor heat pump unit 11. The indoor unit 12 is the indoor unit 12 in a tri-generation air conditioning system, such as an air conditioner indoor unit 12 or a floor heating system. The outdoor heat pump unit 11 has cooling, heating, and domestic hot water supply functions. This application utilizes the hot water supplied by the domestic hot water supply function of the outdoor heat pump unit 11.

[0051] like Figure 1 As shown, in some embodiments, the water tank 2 is located outside the housing of the outdoor heat pump unit 11. For example... Figure 2 As shown, in some embodiments, the water tank 2 is located inside the housing of the outdoor heat pump unit 11. The position of the water tank 2 can be flexibly set according to the actual installation location.

[0052] like Figure 2 As shown, in some embodiments, the outdoor heat pump unit 11 includes a drive plate 111 and a heat pump assembly 112. The drive plate 111 is connected to the heat pump assembly 112, the solar power generation device 3 is electrically connected to the drive plate 111, and the heat pump assembly 112 is connected to the water tank 2. The solar power generation device 3 converts solar energy into electrical energy through the photoelectric effect, and the converted electrical energy is directly transmitted to the drive plate 111 to provide power for the operation of the drive plate 111 and the heat pump assembly 112.

[0053] like Figure 2 As shown, in some embodiments, the outdoor heat pump host also includes a battery pack 113, the solar power generation device 3 is electrically connected to the battery pack 113, and the heat pump assembly 112 and the drive plate 111 are respectively electrically connected to the battery pack 113.

[0054] It is understandable that the solar power generation device 3 converts solar energy into electrical energy through the photoelectric effect. The converted electrical energy can be directly transmitted to the drive plate 111 to provide power for the operation of the drive plate 111 and the heat pump assembly 112. Excess electrical energy can also be stored in the battery pack 113. In the absence of direct power supply from the solar power generation device 3, the battery pack 113 can provide the power required for the operation of the drive plate 111 and the heat pump assembly 112.

[0055] The outdoor heat pump unit 11 includes components such as a compressor, evaporator, condenser, four-way valve, and domestic hot water heat exchanger. These components are connected to enable the tri-generation air conditioner to provide cooling, heating, and domestic hot water supply functions. This application does not modify the specific structure of the heat pump assembly 112, and will not elaborate further here.

[0056] like Figure 1 As shown, in some embodiments, the water tank 2 includes a cold water tank and a hot water tank. The outlet of the cold water tank is connected to the inlet of the heat pump assembly 112, the outlet of the heat pump assembly 112 is connected to the inlet of the hot water tank, and the outlet of the hot water tank is connected to the snow melting device 4. Optionally, the inlet of the cold water tank is connected to a tap water supply pipe to input tap water into the cold water tank. The water in the cold water tank can be transported to the outdoor heat pump host 11 and exchanged with the heat exchanger in the heat pump assembly 112 to obtain hot water. The hot water is then transported to the hot water tank and output from the outlet of the hot water tank to the snow melting device 4 for de-icing the solar panels 31. In some embodiments, the outlet of the hot water tank is also provided with a domestic water interface 23. The domestic water interface 23 can be equipped with water-using appliances, and the hot water from the hot water tank can be transported to the domestic water interface 23 to supply the hot water needed for domestic use.

[0057] In some embodiments, the outlet of the snow melting device 4 can directly discharge the heat-exchanged water. In other embodiments, the outlet of the snow melting device 4 can also be connected to the cold water tank 21 of the water tank 2 through a return water pipe.
