Solar energy semiconductor air conditioning system

[0010] The specific structure, working process and best implementation mode of the present invention will be further described below in conjunction with the accompanying drawings.

[0011] figure 1 The structural diagram of the solar semiconductor air-conditioning system provided by the present invention. The air conditioning system includes a semiconductor refrigeration/heating module 4 arranged in a cooling/heating space 5, a solar photoelectric converter 1 for supplying DC power to the semiconductor refrigeration/heating module, an energy storage device 2 for storing excess electricity, and A numerical control matcher 3 electrically connected with the solar photoelectric converter, the energy storage device and the semiconductor refrigeration/heating module. The solar photoelectric converter is composed of a plurality of polycrystalline silicon battery panels, which are installed outdoors; the battery panels are connected in series or in parallel to provide different charging voltages and system operating voltages. When the electricity generated by the solar photoelectric converter is sufficient, the electric drive cooling/heating module generated by the solar photoelectric converter cools or heats the cooling/heating space, and the excess electricity is charged into the energy storage device 2; When the electricity generated by the solar photoelectric converter is insufficient, the energy storage device 2 drives the cooling/heating module to work. The numerical control matcher 3 is used to control the current of the system. When the system current exceeds the allowable current of the numerical control matcher, the power supply is automatically cut off to protect the cooling/heating module; when the capacity of the energy storage device is lower than 30% of the rated capacity of the energy storage device , or when the discharge voltage of the energy storage device is lower than 70% (11V) of the rated discharge voltage, the load connected to the energy storage device will be automatically cut off to protect the energy storage device.

[0012] The semiconductor refrigeration/heating module described in the present invention adopts one or multiple in parallel, and each semiconductor refrigeration/heating module is composed of a fixed carrier 7 and a plurality of refrigeration/heating units 6 installed on the fixed carrier and fixing bolts 13 . Each cooling/heating unit includes a semiconductor thermopile 8, a finned radiator 9 located at the hot end of the thermopile, a finned radiator 10 located at the cold end of the thermopile, and a radiator located between the hot end radiator and the cold end radiator. The heat shield 11 between them and the small centrifugal fans 12 respectively fixed on the fins of the radiator and the radiator, and the junction of the radiator and the radiator and the thermopile are sealed and fixed with heat-conducting silica gel. Finned radiators and finned radiators have curved fins, made of aluminum, such as figure 2 , 3 shown.

[0013] Switching between cooling and heating functions of the cooling/heating module is determined by the direction of the system current. By switching the power polarity of the solar power system, the cooling and heating functions of the indoor module can be changed. When cooling is required, the cold end of the cooling/heating module is switched indoors, and the small axial flow fan located in the cold end radiator in the module blows cold air into the room, so as to achieve the purpose of rapid cooling; when heating is required , switch the hot end of the cooling/heating module indoors, and the small axial flow fan located in the hot end radiator in the module blows hot air into the room, so as to achieve the purpose of rapid heating.

[0014] The cooling capacity and heating capacity of each cooling/heating module can be adjusted by adjusting the number of cooling units in the cooling/heating module. One or more semiconductor refrigeration/heating modules can be used in parallel to adjust the cooling and heating capacity of the entire solar semiconductor air conditioning system.

[0015] The cooling/heating space can be made of color steel plates, and the placement of the cooling module is reserved on the top of the four walls of the room and the top of the room. When a location is not needed, the location can be sealed with the reserved material when making the house. In the case of insufficient cooling capacity or heating capacity, it can be solved by increasing the number of cooling units in each cooling/heating module or adding cooling/heating modules at unused placement positions.

[0016] The working principle of the present invention is as follows:

[0017] When cooling is required, after the semiconductor thermopile 8 is energized, one end heats up (hot end), and the other end cools down (cold end), and the cold end side is located indoors; the electricity generated by the solar photoelectric converter 1 passes through the numerical control matcher 3 and the energy storage device 2 Provided to the semiconductor refrigeration module 4 at this time; the finned radiator 10 at the cold end of the semiconductor thermopile 8 is affected by the temperature drop at the cold end, and the temperature drops rapidly, and is fixed on the fins 10 of the radiator at the cold end. The small fan 12 sucks the indoor air from the inlet of the fan 12, and then bulges out from around the fins, the temperature of the air sucked by the fan flows through the fin radiator 10, and the temperature drops, and the cooled cold air is blown into the room, thereby achieving cooling Cooling effect; the finned radiator 9 and small axial fan 12 located outside dissipate the heat generated by the hot end of the semiconductor thermopile 8 to the outdoor environment; after the cooling capacity and the cooling load required by the cooling space are balanced, the semiconductor refrigeration module 4 The working status tends to be stable.

[0018] When heating is required, the current direction during cooling is changed. The cold end of the semiconductor thermopile 8 originally located indoors becomes the hot end, and the hot end of the semiconductor thermopile originally located outdoors becomes the cold end. Correspondingly, the heat dissipation originally located at the hot end The radiator 9 and the radiator 10 at the cold end become the radiator 10 and the radiator 9 during heating; the axial flow fan 12 of the radiator in the room sucks the indoor air into the finned radiator from the fan 12 inlet, and the ribs The fin radiator heats the sucked air, and the heated air is blown into the room by the fan 12, thereby achieving the heating effect. Since the temperature of the outdoor radiator 10 is higher than the ambient temperature (under the condition that the ambient temperature is less than 2° C.), it also needs to dissipate heat to the environment. When the power input to the semiconductor heating module 4 is equal to the sum of the heat dissipation of the cold end radiator 10 and the hot end radiator 9, the working state of the semiconductor heating module tends to be stable, and the indoor temperature is basically stable at this time.
