Résumé

This article proposes a simplified steady-state model of a single-stage vapour-compression plant. The model developed is mainly based on well-known physical equations and partially based on empirical and parametrical correlations. The model results are validated using experimental data taken from a test bench in a wide range of operating conditions and working with three refrigerants (R134a, R407C and R22). The agreement between the model predictions and the actual values is found to be within plus or minus 5% for mass flow rate and specific refrigerating effect and plus or minus 10% for the rest energy parameters.
