Refrigerant Circuit With RESTRICTOR And Reservoir
HP- High pressure side of refrigerant circuit.
LP- Low pressure side of refrigerant circuit.
| Component | Aggregate state of refrigerant | Pressure (bar pressure) | Temperature in Celsius |
|---|---|---|---|
| -1- A/C compressor, high pressure side | Gas | up to 20 bar (290.08 psi) | up to +70 °C |
| -2- Condenser | From gas to vapor to fluid | up to 20 bar (290.08 psi) | up to +70 °C |
| -3- Restrictor | From fluid to vapor | High pressure side up to 20 bar (290.08 psi); low pressure side greater than 1.0 bar (14.5 psi) | High pressure side up to +60 °C; low pressure side warmer than -4 °C (24.8 °F) |
| -4- Evaporator | From vapor to gas | Greater than 1.0 bar (14.5 psi) | Warmer than -4 °C |
| -5- Reservoir | Gas | ||
| -6- A/C compressor, low pressure side | Gas |
Pressures on the low pressure side are maintained at approximately 2 bar (29.01 psi) absolute pressure (corresponds to approximately 1 bar (14.5 psi) positive pressure) by a "regulating" A/C compressor also at various engine speeds. However, this applies only within the performance range of the A/C compressor; if the performance limits of the A/C compressor are exceeded. Refer to Refer to PRESSURES, CHECKING .
For vehicles with a A/C Compressor Regulator Valve -N280-, the pressure on the low pressure side is changed by the valve activation.
