Volkswagen Golf Service & Repair Manual: Distribution of the refrigerant circuit components and their influence on
the high-pressure and low-pressure sides
| On the high-pressure side, there are the condenser, the
receiver and the restrictor or expansion valve that acts as the
separation between the high-pressure fluid and low-pressure
fluid sides. |
| High pressure is created because the restrictor or expansion
valve forms a restriction and holds back the refrigerant,
leading to increased pressure and temperature. |
| Excessive pressure results if the circuit is filled with too
much refrigerant or refrigerant oil, or the condenser is dirty,
the radiator fan is defective, there is a blockage in the system
or there is moisture in the refrigerant circuit (causing the
restrictor or expansion valve to ice up). |
| On the low-pressure side, there are the evaporator, the
reservoir, the temperature sensor for the evaporator and the air
conditioner compressor that acts as the separation between the
high-pressure and low-pressure gas sides. |
| A loss of pressure in the system can be due to loss of
refrigerant, restrictor or expansion valve failure (not creating
a restriction), defective air conditioner compressor or an
iced-up evaporator. |
