Audi Q5: Refrigerant Circuit Components Allocation, High and Low Pressure Sides
READ NEXT:
High pressure side are the condenser, receiver/dryer and
restrictor or expansion valve to separate the high and low
pressure liquid ends.
High pressure results from the restrictor or expansion valve

Extremely Dangerous Due to High-Voltage
The high-voltage system is under high-voltage. Death or serious
bodily injury by electric shock.

The condenser conducts heat from compressed refrigerant gas
to the ambient air.
This condenses the refrigerant gas to fluid.

The refrigerant circuit was completely empty (for example
with larger leak or cracked hose)
Note
In the event of only a minor leak with slow escape of
refrigerant (e.g. at a small leakage point), the amount of
refrigerant oil lost and the amount of moisture penetrating is
not sufficien
