The high-temperature heat generated by the high-speed rotation of the screw of the air compressor is also subjected to friction heating, the generated high-temperature heat is mixed by adding lubricating oil of the air compressor to form oil/gas steam which is discharged out of the machine body, the heat of the high-temperature oil/gas flow is equal to 3/4 of the input power of the air compressor, the temperature of the high-temperature oil/gas flow is usually 80-100 ℃, the heat energy is abandoned to be discharged into the atmosphere in an endless mode due to the requirement of the operation temperature of the machine, namely the heat dissipation system of the air compressor is used for meeting the requirement of the operation temperature. In the prior art, a water cooling air compressor is generally used for cooling, and water is heated and then used for producing hot water required by life. But the temperature of hot water obtained by heating is difficult to control, so that heat energy is wasted in a water using link, and the energy utilization efficiency is not high.
When the air compressor runs, electric energy is converted into compression potential energy, when an object is compressed, heat can be generated due to the extrusion of molecules, 70% -90% of electric energy consumed by a motor of the object is converted into heat energy, and therefore energy waste can be caused.
