Méthode simple pour améliorer la performance des évaporateurs industriels sous les conditions de givrage.

Simple method to improve the performance of industrial evaporators under frosting conditions.

Résumé

This paper describes a theoretical model of a large-scale, ammonia-fed evaporator coil used in an industrial refrigeration system and operating under low temperature air and refrigerant conditions that are typically encountered in refrigerated storage spaces. The model is used to simulate the performance of counter- and parallel-flow circuited evaporator coil designs under frosting conditions. The counter-flow frost model is validated using in-situ data obtained from a field-installed evaporator coil. The performance of an evaporator in a parallel-flow circuit arrangement is simulated and compared to counterflow circuiting. The effects of coil circuiting are evaluated in terms of frost distribution across the evaporator coil and the associated reduction in cooling capacity.
