Energy saving in high-pressure reciprocating air compressor

Air compressors account for a significant amount of electricity usage in Indian industries. The production of compressed air is one of the expensive processes practised in manufacturing industries. Our major aim in this project is to apply an energy recovery technique and on load reduction technique in high-pressure reciprocating air compressor. We applied our custom-designed energy recovery techniques and also analysed the limitation and the risks involved in the proposed technique. In the conventional method, the hot pressurised air coming out of the blow-moulding process is emitted into atmosphere, whereas in the proposed model the compressed air is recycled to the compressor receiver; also further energy reduction takes place due to reducing the operating pressure by introducing a pressure-reducing valve (PRV). The implementation of PRV reduces the loading time by 96 min/day, and energy consumption is reduced by 365.25 units/day.
