Problems and solutions for liquid refrigerant in refrigeration system - 2
Jun 08, 2018

    Liquid refrigerant Overflow When the expansion valve action failure, or evaporator fan failure or by air filter occlusion, liquid refrigerant will overflow in the evaporator, liquid rather than steam through the suction pipe into the compressor. In the unit operation, because the liquid overflow diluted frozen oil and caused the compressor moving parts wear, oil pressure to reduce the hydraulic safety device action, so that the crankcase lost oil. In this case, if the shutdown, the refrigerant migration will occur rapidly, resulting in the restart when the liquid strike.
