Abstract: Through the analysis and calculation of the compression and cooling process of the oil-free screw air compressor, this
paper obtained the heat that can be recovered by the air compressor. Combined with the user's heat parameters, the waste heat
recovery system was designed. Under the premise of normal operation of the air compressor, the heat recovery can reach 60% of
the input power of the air compressor, which was of good economic and environmental benefits.

Key words: oil-free screw air compressor; waste heat recovery system; thermal parameters; heat recovery
