Abstract

An air conditioning system,may include a cooling circuit,, a heating circuit,and a variable displacement compressor,as a driving source for both the heating and cooling circuits and may be utilized in a vehicle-mounted air conditioning system. In such case, the driving shaft,of the compressor,is connected to and driven by a car engine,. In order to decrease the compressor output discharge capacity during an abnormally high pressure state, high-pressure refrigerant in the discharge chamber,is released into the driving chamber,to increase the driving chamber pressure. The high-pressure refrigerant can be released from the discharge chamber,into the driving chamber,utilizing a variety of different structures.
