Refrigerant Circuit With RESTRICTOR And Reservoir
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2015 Audi S7, 2015 Audi RS 7, 2015 Audi A7 Quattro, 2014 Audi S7, and 2014 Audi RS 7. However, it is still accessible from the selected car via links, so may be relevant.
HP- High pressure side of refrigerant circuit.
LP- Low pressure side of refrigerant circuit.
| Component | Aggregate state of refrigerant | Pressure (bar positive pressure) | Temperature in degrees Celsius |
|---|---|---|---|
| -1- A/C compressor, HP 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 | HP side up to 20 bar LP side greater than 1.0 bar | HP side up to + 60 °C LP side warmer than -4 °C |
| -4- Evaporator | From vapor to gas | greater than 1.0 bar | Warmer than -4 °C |
| -5- Reservoir | Gas | ||
| -6- A/C compressor low pressure side | Gas |
Pressures on A-side are maintained at approximately 2 bar absolute pressure (corresponds to approximately 1 bar positive pressure) 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.
Arrows point in direction of refrigerant flow.
