摘要：

A semi-empirical modeling approach for simulating the steady-state behavior of vapor-compression refrigeration systems is presented in this study. The model consists of first-principles algebraic equations adjusted with experimental data obtained from the refrigeration system under analysis. Measurements of the relevant variables were taken at several positions along the refrigeration loop, supplying data for the calibration of the computer model. The predicted values of refrigeration capacity and power consumption when compared with experimental data were within +/- 10% error bands. The model was also employed to assess the effect of various system parameters on the refrigerator performance. Although a top-mount frost-free refrigerator was chosen for this study, the modeling methodology can be easily extended to other types of refrigeration systems, from domestic refrigerators to heat pumps.
