Page 9: Economizer
Operating Principles Economizer The economizer system's two main components are an electronic expansion valve (EXV) and a brazed plate heat exchanger (BPHE). The liquid flow leaving the condenser is routed through the economizer BPHE. One side is the economizer refrigerant flow and the other side is the evaporator refrigerant flow. -
