Compressor back to the control method oil system

The present invention discloses a method for controlling oil return to the compressor system, the oil return to the compressor system includes a compressor, an oil separator, an oil return solenoid valve, oil return capillary tube, wound around the outer surface of the controller and the lower portion of the compressor of the band, a compressor, an oil separator, an oil return solenoid valve and the oil return capillary circulation circuit is formed are sequentially connected, back to parallel electrical heating cable and the solenoid valve connected to the controller oil; an oil return solenoid valve is a normally open solenoid valve; a control method comprising opening step off the compressor and compressor step; opening said compressor steps of: when the compressor is turned on, the controller stops power supply to the solenoid valve and the oil return heating cable, heating cable heating was stopped, the oil return solenoid valve open; the oFF compressor steps of: when the compressor stops, the controller back to the oil supply solenoid valve and the heating cable, the heating cable is heated, the oil return solenoid valve is closed. Oil-return valve which employs a normally open type, an air conditioner to improve the reliability of the oil return, the oil return valve fail to solve basically normal oil return problems.
