However, only 15% of energy consumed in the working process of the air compressor of the oil circulation system is converted into air potential energy, and the rest 85% of energy is converted into heat energy. After heat energy is absorbed by circulating oil of the air compressor, the oil temperature is as high as over 85 ℃, but the part of heat energy is generally discharged into the air by cooling equipment carried by the air compressor and is wasted, so that energy consumption loss is caused. In addition, in the process of compressing gas, when the air compressor sucks high-temperature and high-humidity air, the air displacement and the exhaust pressure of the air compressor are reduced, the system efficiency is reduced, the energy consumption of the air compressor unit is increased, and meanwhile certain potential safety hazards exist.
