Abstract
The air conditioning system may include a compressor a heating circuit and a capacity controller The compressor has a suction port a discharge port a driving unit provided within a driving chamber a first passage and a second passage The driving unit may decrease compressor output discharge capacity when the pressure within the driving chamber increases. The first passage may connect the discharge port to the driving chamber and the second passage may connect the driving chamber to the suction port The capacity controller may open the first passage when the refrigerant discharge pressure results predetermined pressure. By opening the first passage the high-pressure refrigerant may be released from the discharge port to the driving chamber through the first passage Thus, the pressure within the driving chamber may increase, the compressor output discharge capacity can be reduced, the abnormally high discharge pressure of the compressor can be alleviated by the reduction in the compressor output discharge capacity.
