In the long time and continue operation, the compressor transform the electric energy to the mechanical energy, and transform the mechanical energy to the wind energy. In the process of transformation from mechanical energy to wind energy, the air is strongly pressed by high pressure which makes the temperature high and this is the common mechanical energy transformation phenomenon for physical sciences. The high temperature heat energy and friction caused by high speed rotation of the screw air compressor discharge from the machine. The amount of heat is equivalent to 3/4 input power of the compressor and the temperature is usually 80?(in winter) , 100?(in summer, autumn). The heat energy is discharged into the air for free, that is the heat radiation system for the compressor will finish the temperature requirement.
