[0023] Please see Figures 1-3 As shown, this utility model is a photovoltaic waste heat utilization type heat pump assisted air supply circulating water cooling tank, comprising:

[0024] The air-cooled circulation assembly includes a heating water tank 11, a water tank 12, a waste heat recovery tank 13, an air-cooled circulation tank 14, a packing box 15, a support frame 16, photovoltaic panels 17, a water distribution pipe 18, and a cooler 19. The water tank 12 is located on one side of the heating water tank 11, the waste heat recovery tank 13 is located inside the water tank 12 on one side, the air-cooled circulation tank 14 is located inside the water tank 12 on the other side, the packing box 15 is fixed to one side of the top of the water tank 12, the support frame 16 is fixed to the top of the water tank 12, the photovoltaic panels 17 are arranged in a group and are fixed at equal intervals to the top of the support frame 16, the water distribution pipe 18 passes through and is fixed to one side of the support frame 16, and the cooler 19 is located on the other side of the water tank 12.

[0025] The heating water tank 11 is used to heat the incoming tap water. The water tank 12 is used for waste heat recovery and air cooling. The waste heat recovery tank 13 recovers the waste heat in the air cooling tank 14. Using the circulating cooling return water that needs to be cooled as a heat source, the heat is transferred to the heating water tank 11. The waste heat of the cooling water can be used to supply domestic hot water above 55°C. The air cooling tank 14 cools the water in the tank. The packing box 15 is used for packing. The support frame 16 is used for connecting the photovoltaic panels 17. The support frame 16 is a photovoltaic roof and also serves as a photovoltaic canopy. It has functions of shading, energy saving and power generation, and can dynamically coordinate cooling load and hot water demand through intelligent control system to achieve precise control of supply and demand deviation. Photovoltaic panel 17 generates clean energy, water distribution pipe 18 is used for water transportation, and cooler 19 is used for water placement. The structure of water distribution pipe 18-filling box 15-air supply cooling pool 14 realizes rapid cooling of water entering at 37℃ and water exiting at 32℃. It uses water distribution pipe 18 and filling box 15 to increase the gas-liquid contact area, and is also equipped with fan 143 to supply air to improve the cooling speed.

[0026] The photovoltaic cells inside the photovoltaic panel 17 form a PN junction structure, and the contact surface forms a built-in electric field. When the energy of solar photons exceeds the band gap of silicon, it will excite valence band electrons to jump to the conduction band, forming electron-hole pairs. Under the action of the built-in electric field, a potential difference will be formed. When connected to an external circuit, the potential difference drives the flow of electrons to form direct current. The output voltage is increased by connecting the cells in series to form a module. Multiple modules form a photovoltaic array. With the help of an inverter, the direct current is converted into alternating current. After being regulated by a controller, it is connected to the energy storage system. This system does not require mechanical moving parts and directly converts solar radiation energy into electrical energy, which has the characteristics of being clean and pollution-free.

[0032] The tap water inlet pipe 111 is used for tap water to enter the heating water tank 11, the hot water outlet pipe 112 is used for hot water output, the evaporator 132 heats the water, the condenser 131 cools the water in the heating water tank 11, the compressor 134 is the power source for the condenser 131 and the evaporator 132, the support column 141 is used for connecting the gas distribution pipe 142, the waste heat recovery tank 13, the evaporator 132, the heating water tank 11 and the condenser 131 together form a heat pump system. This is an energy-saving device that can transfer heat from a low-temperature heat source to a high-temperature heat source. The working principle of the heat pump in this system is to transfer the heat in the circulating cooling water to the heating water tank 11 for domestic water, and recover waste heat for heating domestic water while cooling the water.

[0033] One end of the air distribution pipe 142 extends to the outside of the water tank 12. A fan 143 is fixedly connected to the outer end of the air distribution pipe 142. A water outlet pipe 144 is fixedly connected to the lower side of the outside of the air supply cooling tank 14. A water pump 145 is fixedly connected to one end of the water outlet pipe 144.

[0034] A filter hole is provided at the bottom of the packing box 15. A set of support rods 161 is fixedly connected to the upper inner side of the support frame 16. The bottom end of the support rods 161 is fixedly connected to the top end of the water distribution pipe 18. A connecting pipe 181 is fixedly connected to the bottom end of one side of the water distribution pipe 18. The bottom end of the connecting pipe 181 extends to the upper inner side of the waste heat recovery tank 13.

[0035] A valve 182 is fixedly connected to the outer end surface of the water distribution pipe 18, and through holes 183 are opened on one side of the bottom end of the water distribution pipe 18 and above the inner end of the air distribution pipe 142.

[0036] Air distribution pipe 142 is used for air to enter the air supply cooling pool 14. Fan 143 delivers cool air into air distribution pipe 142.

[0039] Working principle: The cooler 19 delivers water to the water distribution pipe 18, which sprays the water downwards through the through hole 183, allowing the water to pass through the packing box 15 and enter the air-cooled pool 14. At this time, the water-spraying packing further increases the gas-liquid contact area. Then, the fan 143 starts operating, allowing cold air to enter the air distribution pipe 142 through the fan 143. The air distribution pipe 142 sends the cold air into the air-cooled pool 14 through the through hole 183, causing the cold air to cool the water in the air-cooled pool 14. At the same time, the waste heat in the air-cooled pool 14 enters the waste heat recovery pool 13. Inside, the evaporator 132 starts to operate, allowing heat to enter the heating water tank 11 through the evaporator 132 and condenser 131, making the water in the heating water tank 11 hot and enabling the water in the heating water tank 11 to be used as domestic water. After the air-cooled pool 14 is cooled, the cooling water is transported to the cooler 19 through the outlet pipe 144, water pump 145, and installation pipe 192. The cooler 19 then transports the water to the distribution pipe 18 through the connecting pipe 191, and the cycle repeats. During this process, the photovoltaic panel 17 generates electricity using clean energy, thus forming an air-cooled circulating water cooling pool.
