Refrigerant Circuit With RESTRICTOR And Reservoir
Arrows point in direction of refrigerant flow.
A- Low pressure side of refrigerant circuit.
B- High pressure side of refrigerant circuit
| Component | Aggregate State Of Refrigerant | Pressure (Bar Positive Pressure) | Temperature In Degrees Celsius |
|---|---|---|---|
| -1- A/C compressor B-side | Gas | up to 20 bar | up to + 70 °C (158 °F) |
| -2- Condenser | From gas to vapor to fluid | up to 20 bar | up to + 70 °C (158 °F) |
| -3- Restrictor | From fluid to vapor | B-side through 20 bar, A-side greater than 1.5 bar | B-side up to + 60 °C (140 °F), A-side warmer than -4 °C (-25 °F) |
| -4- Evaporator | From vapor to gas | Greater than 1.5 bar | Warmer than -4 °C (-25 °F) |
| -5- Reservoir | Gas | ||
| -6- A/C compressor A-side | Gas |
Pressures on A-side are maintained at approximately 2 bar by 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 PRESSURES, CHECKING .
NOTE:
In vehicles with A/C compressor regulator valve -N280-, the pressure is modified on the low pressure side by the valve.
