Refrigerant Circuit With RESTRICTOR And Reservoir
WARNING: This page is about a different car, the 2016 Volkswagen Beetle, 2015 Volkswagen Beetle, 2014 Volkswagen Beetle, and 2013 Volkswagen Beetle. However, it is still accessible from the selected car via links, so may be relevant.
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 |
| -2- Condenser | From gas to vapor to fluid | up to 20 bar | up to +70 °C |
| -3- Restrictor | From fluid to vapor | B-side to 20 bar, A-side greater than 1.5 bar | B-side up to +60 °C, A-side warmer than -4 °C |
| -4- Evaporator | From vapor to gas | Greater than 1.5 bar | Warmer than -4 °C |
| -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.
