Fluid Collector
In some operating conditions (for example heat pump operation) the receiver/dryer (for example on the condenser) is not incorporated in the refrigerant circuit. The fluid collector -B- collects the refrigerant, and saves it if a specific quantity of refrigerant is not needed and directs it in an uninterrupted stream to the expansion valve (in front of the evaporator in the heater and A/C unit) or to the heat exchanger in the refrigerant circuit of the high-voltage system. Refer to Refrigerant Circuit (vehicle-specific Service Information).
