Etude numérique sur la performance de l'évaporateur des systèmes de conditionnement d'air automobiles.

Numerical study on the performance of the evaporator for car air conditioners.

Résumé

In this study, the method for predicting the performance of multipass type evaporators for automobile air conditioners is developed. The study is based on previous studies of the flow boiling heat transfer and two-phase pressure drop in small diameter tubes. The heat transfer rate, distribution of air/refrigerant temperature, pressure, vapour quality and void fraction are calculated on the various conditions of the evaporator's specification, refrigerant flow and air flow. The effect of various calculation conditions on the heat transfer rate and refrigerant pressure drop in the evaporator are also examined. It is found that the evaporator size can be reduced keeping almost the same outlet air temperature when the optimum specification of the evaporator is selected.
