Volkswagen Polo Service & Repair Manual: Refrigerant Circuit Pressures and Temperatures
WARNING
| When performing work on refrigerant circuit, observe
all generally applicable safety precautions and pressure
vessel regulations. |
|
| The pressures and temperatures in the refrigerant circuit
depend on the current operating conditions (such as engine RPM,
coolant fan level 1, 2 or 3, engine temperature, A/C compressor
on or off) as well as on the effects of outside influences (such
as outside temperature, humidity, desired cooling output). |
| In vehicles with A/C Compressor Regulator Valve -N280-, the
pressure is modified on the low pressure side by the valve. |
| For this reason, values indicated in the following table are
valid only as reference points. They are attained at an engine
speed of 1,500 to 2,000 RPM and an ambient temperature of 20 °C
(68 °F) after about 20 minutes. |
| The connections provided for measuring pressure for the
manometer battery are located in the vehicle-specific
refrigerant circuit. |
| At 20 °C (68 °F) with the engine not running, the pressure
in the refrigerant circuit is 4.7 bar (68.17 psi). Refer to
→ Chapter „Refrigerant R134a Vapor Pressure Table“. |
