Description

technical field

[0001] The invention relates to a refrigeration device, in particular to a refrigerator. Background technique

[0002] Refrigerator is a kind of necessities of life, and it can freeze or keep fresh the food stored in the refrigerator for a period of time. The working principle of an ordinary refrigerator is to generate low temperature inside the refrigerator through repeated cycles of compression, condensation, expansion, and evaporation of the refrigerant.

[0003] The structure of an ordinary refrigerator mainly includes: a compressor, a condenser, an expansion tube and an evaporator. The function of the compressor is to compress the refrigerant from a low-temperature / low-pressure gaseous state to a high-temperature / high-pressure gaseous state; the function of the condenser is to condense the high-temperature / high-pressure gaseous refrigerant output from the compressor into a low-temperature liquid state; the function of the expansion tube is to make the c...
