Fluid Collector
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2024 Audi SQ5, 2024 Audi Q5 e, 2024 Audi Q5, 2023 Audi SQ5, and 2023 Audi Q5 e. However, it is still accessible from the selected car via links, so may be relevant.
In some operating conditions (in heat pump operation, for example), the receiver/dryer (on the condenser, for example) is not incorporated into 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 (vehicle-specific Service Information).
