Reasonably adjust the cold storage evaporator and defrost in time

Reasonably adjust the cold storage evaporator and defrost in time Generally speaking, every increase in the cold storage evaporation temperature can save energy Therefore, under the premise of satisfying the low refrigeration process of the product, the evaporation temperature can be increased as much as possible by adjusting the amount of liquid supplied. The thermal resistance of the frost layer is generally much larger than the thermal resistance of the steel pipe.
