The method comprises the following steps of: (1) electrifying an air conditioning unit; (2) starting the screw compressor when oil temperature of an oil sump reaches a certain value; (3) opening an oil return electromagnetic valve to replenish the oil if the oil level in the oil sump of the screw compressor is lower than a safety oil level; (4) loading in a gradient way until full load is realized when the screw compressor is started; (5) opening the oil return electromagnetic valve to replenish the oil when the oil level of the oil sump during running is lower than the safety oil level, and opening a gas separation oil return electromagnetic valve to return the oil if the load of the screw compressor is less than 20-55 percent; and (6) unloading in a gradient way until the screw compressor is stopped when the screw compressor reaches stoppage conditions. Compared with the conventional method, the method has the characteristic of guaranteeing that the oil level of the lubricating oil in the oil sump of the screw compressor is positioned above the safety oil level in a starting process, an automatic adjustment process, a stoppage process and a protective adjustment process or the time for keeping the oil level below the safety oil level does not exceed 3 minutes.
