synonymThermoelectric refrigeration(Thermoelectric refrigeration) generally refers to solar semiconductor refrigeration technology
Semiconductor refrigeration is a kind of refrigeration method using thermoelectric refrigeration effect, so it is also called thermoelectric refrigeration or thermoelectric refrigeration.Semiconductor coolerThe basic element ofP-type semiconductorElement and oneN-type semiconductorThermocouple connected by elements.
Chinese name
Semiconductor refrigeration technology
Foreign name
Thermoelectric cooling
Alias
Thermoelectric refrigeration or thermoelectric refrigeration
When the DC power supply is connected, the current direction of the upper connector is N-P, the temperature decreases, and absorbs heat, forming a cold end;The current direction of the lower connector is p-n, the temperature rises, and heat is released, forming a hot end.Several pairs of thermocouples are connected to form a commonly used thermopile. With the help of various heat transfer devices, the hot end of the thermopile is continuously cooled, and a certain temperature is maintained. The cold end of the thermopile is placed in the working environment to absorb heat and generate low temperature, which is the working principle of semiconductor refrigeration.The solar semiconductor refrigeration system uses the thermoelectric refrigeration effect of semiconductor to directly supply the required DC power from the solar cell to achieve the effect of refrigeration and heating.

Solar semiconductor refrigeration system is composed of solar energyPhotoelectric converter, numerical control matcher, energy storage equipment and semiconductor refrigeration device.The solar photovoltaic converter outputs direct current, one part of which is directly supplied to the semiconductor refrigeration device, and the other part is stored in the energy storage equipment for use in cloudy days or at night, so that the system can operate normally all day long.
solar energyPhotoelectric converterYou can chooseCrystalline silicon solar cellOr nanocrystalline solar cell, select the model of solar cell according to the capacity of the refrigeration device.In sunny days, the solar photovoltaic converter converts the solar radiation energy on its surface into electrical energy for use by the whole system.
The numerical control matcher makes the energy transmission of the whole system always in the best matching state.At the same time, it controls the overcharge and discharge of energy storage equipment.
Energy storage equipment generally uses batteries, which store part or all of the energy output from the photoelectric converter for use when the solar photovoltaic converter does not output, so that the solar semiconductor refrigeration system can operate around the clock.
