Fluid Collector
WARNING: This page does not describe the selected car, but rather 23 other vehicles, including the 2017 Audi S5, 2017 Audi A5 Quattro, 2016 Audi S5, 2016 Audi A5 Quattro, and 2015 Audi S5. However, it is still accessible from the selected car via links, so may be relevant.
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 .
