Defrosting fin evaporator
In the refrigeration system, the evaporator is a key heat transfer component, and its surface temperature is usually lower than the ambient temperature, especially when operating in a low temperature and humid environment, it is easy to frost on the surface of the evaporator. Defrosting fin evaporators are necessary.

Defrosting method
Electric defrost
Principle: Use an electric heater to heat the surface of the evaporator to melt the frost layer.
Application scenario: Especially suitable for cold air blower evaporator.
Hot gas defrosting
Use the high temperature and high pressure refrigerant gas produced by the compressor to heat the evaporator to defrost.
Natural defrosting
Principle: Rely on the increase of the ambient temperature or the heat accumulation of the evaporator itself to melt the frost layer naturally.
Application scenario: Applicable to situations with high ambient temperature or long downtime.
Liquid flush
Principle: The use of high pressure water or low pressure refrigerant liquid to wash the evaporator, the frost layer washed away.
Application scenario: Suitable for large refrigeration systems or evaporators that are difficult to defrost by other methods.
