Description

technical field [0001] The present invention relates to the technical field of refrigeration, and more specifically relates to a combined internal and external source thermoelectric hybrid refrigeration device. Background technique [0002] Existing refrigeration devices, such as central air-conditioning units, refrigerators, etc., mainly include compressors, condensers and evaporators. When working, the compressor compresses the gaseous refrigerant into a high-temperature and high-pressure liquid refrigerant, and then sends it to the condenser. Medium cooling, the cooled refrigerant enters the evaporator again, and the refrigerant absorbs a large amount of heat during the evaporation process in the evaporator. Through heat exchange, it can produce frozen water or blow the gas through the evaporator through a fan. Cool air for cooling purposes. When heating, the pipes of the condenser and the evaporator can be exchanged through the four-way valve (this function is only avai...

AI Technical Summary

Problems solved by technology

[0003] The compressor in the prior art is mainly driven by a built-in motor when working, and the motor is directly connected to the power grid. When the power grid is cut off, the refrigeration device cannot be used normally, and the built-in motor is prone to insufficient power.

The prior art also uses a solar device to drive the compressor to achieve the purpose of energy saving, but the solar device is affected by the weather, resulting in low reliability
