Fluid Collector
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2022 Audi SQ5, 2022 Audi Q5 e, 2022 Audi Q5, 2021 Audi SQ5, and 2021 Audi Q5 e. 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 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 repair information).
