Volkswagen Golf Service & Repair Manual: Pressures and temperatures in the refrigerant circuit
WARNING
When working on the refrigerant circuit, observe
generally applicable safety rules and the Regulations
for Pressure Tanks. |
|
The pressures and temperatures in the refrigerant circuit
depend on the momentary operating conditions (e.g. engine speed,
speed 1, 2, or 3 of radiator fan, engine temperature, whether
air conditioner compressor is on or off) as well as
environmental influences (e.g. ambient temperature, humidity,
required cooling output). |
In vehicles with air conditioner compressor regulating valve
-N280-, the pressure on the low-pressure side is varied by
activating the valve. |
Therefore, the values given in the following tables may only
be considered as guidelines. They occur at an engine speed of
1,500 to 2,000 rpm and an ambient temperature of 20°C after
about 20 minutes. |
The locations of connections provided for pressure
measurements can be found in the vehicle-specific coolant
circuits. |
At 20°C and with the engine stopped, the refrigerant circuit
will adjust itself to a pressure of 4.7 bar positive pressure
→ Chapter. |

Testing a Child Safety Seat
Before seating a child, always make sure the child safety
seat is not loose:
1. Hold the child safety seat by the belt path and try to
slide the safety seat from side to side and front to
back.
2. If the seat moves more than one inch (2.5 cm), it is
too loose. Tighten the belt or reconnect the ...
Description and function of the airbags
First read and observe the introductory information
and safety warnings The airbags can protect vehicle occupants during frontal
and side collisions by reducing their movement in the direction of the collision.
When an airbag is triggered, it is inflated by a gas generator. This causes the ...
