Early practitioners of industrial refrigeration systems found they could increase the capacity of evaporators by supplying excess liquid refrigerant to the unit (overfeeding). In evaporators configured to operate with overfeed, the quantity of liquid refrigerant supplied isgreater than the minimum amount required to meet the cooling loads as itundergoes the phase change from liquid to vapor. In this case, a mixture of low temperature liquid and vapor leaves the evaporator and returns to a vessel designed to separate the liquid from the vapor prior to the vapor being recompressed
