System Overview - Refrigerant Circuit With Electrically-Driven A/C Compressor (With Or Without Battery Cooling Module)
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2017 Audi S3, 2017 Audi RS 3, 2017 Audi A3 Quattro, 2017 Audi A3, and 2016 Audi S3. 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 repair information).
HD = High Pressure Side
ND = Low Pressure Side
