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 stores it temporarily if a certain amount of refrigerant is not needed, and then 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 high-voltage system coolant circuit. Refer to the appropriate service information in AIR CONDITIONING, REFRIGERANT CIRCUIT - 1 , REFRIGERANT CIRCUIT - 2 , REFRIGERANT CIRCUIT 1234yf - 2 , REFRIGERANT CIRCUIT GENERAL INFORMATION R134a or REFRIGERANT CIRCUIT R134a .
