Abstract

The invention provides a control method of an electromagnetic valve for air conditioner liquid injecting cooling. An air conditioner comprises a control unit and the electromagnetic valve used for controlling liquid refrigerants of a compressor of the air conditioner to be bypassed to the low-pressure side of the compressor. The control unit is used for controlling the electromagnetic valve to be opened and closed. The control unit controls the electromagnetic valve to be opened and closed according to the magnitude relation of the exhaust temperature T1 of the compressor and the exhaust temperature preset value and/or the magnitude relation of the exhaust superheat degree of the compressor of the control unit and the preset temperature value. The electromagnetic valve is controlled to be opened and closed by increasing the magnitude relation of the exhaust superheat degree and the preset temperature value. Thus, compressor oil has a good lubrication effect, the service life of the compressor is prolonged, and the reliability of the compressor is improved.
