The air conditioning system 100 may include a compressor 101, a heating circuit 152, and a capacity controller 181. The compressor 101 has a suction port 116, a discharge port 120, a driving unit 130 provided within a driving chamber 110, a first passage 201 and a second passage 105. The driving unit 130 may decrease compressor output discharge capacity when the pressure within the driving chamber 110 increases. The first passage 201 may connect the discharge port 120 to the driving chamber 110 and the second passage 105 may connect the driving chamber 110 to the suction port 116. The capacity controller 181 may open the first passage 201 when the refrigerant discharge pressure results predetermined pressure. By opening the first passage 201, the high-pressure refrigerant may be released from the discharge port 120 to the driving chamber 110 through the first passage 201. Thus, the pressure within the driving chamber 110 may increase, the compressor output discharge capacity can be reduced, the abnormally high discharge pressure of the compressor 101 can be alleviated by the reduction in the compressor output discharge capacity. <IMAGE> |
