In this paper, the simulation model of a hybrid cooler combining vapor compression and natural circulation cycles was developed to investigate the effects of operating parameters on the system performance. The model for the vapor compression cycle was developed based on the ORNL (Oak Ridge National Laboratory, 1983) heat pump model. The sectorial thermal resistance model was used to predict the performance of the natural circulation cycle. The predicted data using the model were compared with the measured data to decide appropriate heat transfer correlations and then to validate the model. The predicted data in the vapor circulation and natural circulation mode were consistent with the measured data within relative deviations of 2.3% and 5.5%, respectively. The predicted results of the vapor compression cycle showed a good agreement with the measured data.
