Simple but efficient emthods for estimation of valve loss,capacity loss due to suction valve throttling and heat transfer in cylinder

摘要

The paper addresses to engineers who do desing ad optimisation work in the field of reciprocating compressors.Formulae based n theoretical and empirical considerations are given which allow to predict the valve losses.Suction valve losses also result in a reduction of capaciyt.A formula for th eprediction of this capacity loss is presented.The heat ransfer process from cylinder wals to gas druign intake is discussed.A new approach based on heat conduction is proposed which results in a simple formula for heat transfer and the according capacity loss.
