Summary

This paper presents an approach to investigate the refrigerant’s influence on a reciprocating compressor. High-light of this model is the one-dimensional semi-physical approach, which is general fluid independent. Compared to compressor models from literature, this model handles with real gas behaviour. The applied fluid property models have been specifically designed to be fast and accurate. This is given by the implementation of a hybrid approach based on the simplified Helmholtz Equation of State (EoS) and polynomial functions. Considering rotational speeds between 30 s-1 and 70 s-1 and pressure ratios from 5 up to 13, results show a maximum isentropic efficiency of 67 %, 63 %, 66 %, 53 % for the refrigerants R410A, R134a, R744, R32, respectively.
