System Overview - Refrigerant Circuit With Electrically-Driven A/C Compressor (With Or Without Battery Cooling Module)
WARNING: This page is about a different car, the 2022 Volkswagen ID.4 and 2021 Volkswagen ID.4. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The arrows indicate the refrigerant flow direction.
The following illustration shows a refrigerant circuit with an expansion valve and a second evaporator for cooling the battery and an inner heat exchanger as an example.
The layout of the refrigerant circuit is vehicle-specific. Refer to Refrigerant Circuit (vehicle-specific Service Information).
