Refrigerant Circuit with Restrictor and Reservoir

     
Component Aggregate state of refrigerant Pressure bar (psi) positive pressure Temperature in degrees Celsius (Fahrenheit)
-1- A/C compressor B-side Gas up to 20 (290 psi) up to 70 (158)
-2- Condenser From gas to vapor to fluid up to 20 (290 psi) up to 70 (158)
-3- Restrictor From fluid to vapor B-side to 20 (290 psi), A-side greater than 1.5 (21.8 psi) B-side up to 60 (140 psi), A-side warmer than -4 (25)
-4- Evaporator From vapor to gas Greater than 1.5 (21.8 psi) Warmer than -4 (25)
-5- Reservoir Gas    
-6- A/C compressor A-side Gas    
 
Pressures on A-side are maintained at approximately 2 bar (29 psi) 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 → Chapter "Pressures, Checking".
  Note
In vehicles with A/C Compressor Regulator Valve -N280-, the pressure is modified on the low pressure side by the valve.
