Evaporating temperature of refrigerant
Webbetween load and evaporating refrigerant. Increased TD in the evaporator indicates a decrease in capacity. Capacity is further reduced to the extent that the vapor pressure of a refrigerant/oil solution is less than that of a refrigerant alone. If suction pressure controls the compressor, it stops running at a higher temperature when vapor ... WebNov 2, 2003 · Refrigerant is changed from a liquid to a vapor. This is called evaporation.
