Embodiment Construction
[0015] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0016] Such as figure 1 As shown, the variable capacity compressor according to the present invention includes a suction port, an exhaust port and a medium-pressure port, the discharge port and the medium-pressure port are connected through a first pipeline, and the suction port and the medium-pressure port are connected through a second pipe The first solenoid valve 10 is arranged in series on the first pipeline, and the second solenoid valve 20 is arranged in series on the second pipeline. The variable displacement compressor also includes a suction temperature detection device 31 corresponding to the suction port, and An exhaust gas temperature detection device 32 is provided corresponding to the exhaust port, and a medium pressure temperature detection device 33 is provided corresponding to the medium pressure port. The present invention detects the t...

The invention provides a variable-capacity compressor and a control method. The variable-capacity compressor comprises an air suction port, an air exhaust port and a medium-pressure port. The air exhaust port is connected with the medium-pressure port through a first pipeline. The air suction port is connected with the medium-pressure port through a second pipeline. A first electromagnetic valve is arranged on the first pipeline in series. A second electromagnetic valve is arranged on the second pipeline in series. The variable-capacity compressor further comprises a sucked air temperature detection device corresponding to the air suction port, an exhaust air temperature detection device corresponding to the air exhaust port, and a medium-pressure temperature detection device corresponding to the medium-pressure port. The sucked air temperature detection device, the exhaust air temperature detection device and the medium-pressure temperature detection device are arranged on the variable-capacity compressor to be used for conducting temperature detection on the air suction port, the air exhaust port and the medium-pressure port respectively, and thus whether the first electromagnetic valve and the second electromagnetic valve are opened or closed normally can be judged according to detected temperatures, and whether the first electromagnetic valve and the second electromagnetic valve are connected reversely can be further judged.
Description
technical field [0001] The invention relates to the field of compressors, in particular to a variable capacity compressor and a control method. Background technique [0002] Some of the existing medium-pressure compressors achieve medium pressure through the cooperation of several solenoid valves. However, during the production, installation, testing and maintenance of compressors, it is very likely that the driving coils of several solenoid valves will be reversed, resulting in control errors of the compressor system. Contents of the invention [0003] The invention aims to provide a variable capacity compressor capable of preventing reverse connection and a control method. [0004] The invention provides a variable capacity compressor, which includes a suction port, a discharge port and a medium-pressure port, the discharge port and the medium-pressure port are connected through a first pipeline, and the suction port and the medium-pressure port are connected through a ...
