Refrigerant Circuit With Restrictor and Reservoir

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.










Pressures on A-side are maintained at approx. 2 bar by the "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 Pressures, checking on vehicles.

NOTE: In vehicles with A/C Compressor Regulator Valve N280, pressure is modified on the low pressure side by the valve.
