Refrigerant circuit with restrictor and reservoir
 

     
Component Overall state of the refrigerant Pressure (in bar) Temperature in degrees Celsius
-1- Air conditioning system compressor B-side Gas up to 20 bar to +70°C
-2- Condenser from gas through vapour to liquid up to 20 bar to +70°C
-3- Restrictor from liquid to vapour B-side up 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 vapour to gas greater than 1.5 bar warmer than -4°C
-5- Reservoir Gas    
-6- Air conditioning system compressor A-side Gas    
 
The pressures on the A-side are held at approx. 2 bar by the “regulating” air conditioner compressor even at differing engine speeds. This applies however only within the rated range of the air conditioner compressor ; if the rated range of the air conditioner compressor is exceeded, the pressure will increase → Chapter.
  Note
In vehicles with air conditioner compressor regulating valve -N280-, the pressure on the low-pressure side is varied by activating the valve.
