Fluid Collector
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2022 Audi S5, 2022 Audi RS 5, 2021 Audi S5, 2021 Audi RS 5, and 2021 Audi A5 Quattro. 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 Refrigerant Circuit .
