ABSTRACT:
An automotive air conditioning system includes a compressor with a variable displacement mechanism, a condenser, a decompression device and an evaporator serially arranged to form a closed refrigerant circulation path. A conduit connects an outer side of the compressor to an intermediate portion of a fluid conduit passing through the condenser. A pressure adjusting mechanism is disposed in the bypass conduit to adjust the pressure of refrigerant in the condenser. The pressure adjustment mechanism permits the automotive air conditioning system, which includes a compressor with a variable displacement mechanism, to maintain the amount of refrigerant circulated in the system at a desired level under small, as well as large, air conditioning loads.
