What about the cooling performance of industrial refrigerators?
screw type refrigerator ventilation is not smooth. The heat transfer effect of the evaporator is poor, and the refrigerant is evaporated, and continues to evaporate in the air return pipe and the compressor. Therefore,
expansion valve through small or blocked. The refrigerant will reduce the amount of liquid, the evaporation temperature of the air conditioner is low, and the evaporator fin will be frosted, and the refrigerant will not evaporate. It will continue to evaporate into the air return pipe and compressor. 4
dry filter part blocked. Blocking the filter will reduce the refrigerant supply, the water cooler evaporation temperature is low, the evaporator fin will be frosted, refrigerant evaporation, flow into the back pipe and compressor continue to evaporate.
When the refrigerant is compressed, the compressor begins to vaporize and absorb heat, so it is frosting. Normally, the compressed refrigerant begins to vaporize only when it is in the evaporator. Reason: 1, less refrigerant.
