Résumé

A semi-empirical mathematical model is proposed to simulate the unsteady behavior of mass flow rate and power of reciprocating compressors. The model is based on thermodynamic equations fitted to calorimeter data sets of two compressors. The curve fitting suggests linear correlations between the measured values and the thermodynamic equations. Comparisons of computed and measured values of mass flow rate and power, in transient regime, were conducted for two fitted compressor curves. A good agreement of results was found for both compressors in start-up tests. One can conclude that the proposed semi-empirical model can be safely applied to dynamic simulations of the whole refrigeration system.
