Abstract
An air conditioning system,may include a compressor,having a driving chamber,, a heating circuit,and a controller,. This system may release high pressure refrigerant from the compressor discharge port,into the compressor driving chamber,by opening a capacity control valve,when the discharge pressure of the refrigerant discharged from the compressor,exceeds a predetermined reference value. By increasing the pressure within the driving chamber,, the compressor discharge capacity can be reduced. As a result, the discharge pressure of the compressor,will be reduced by the reduction in the compressor discharge capacity. Further, the controller,may decrease the reference value in accordance with a value related to change in the discharge pressure. As a result, the capacity control valve,can be opened at an early stage of the increasing of the discharge pressure if the discharge pressure increases rapidly.
