Etude sur l'évaporateur d'un réfrigérateur au CO2 : caractéristiques du coefficient de transfert de chaleur et de la chute de pression du mélange CO2/huile.

Résumé

The effect of lubricating oil on evaporation heat transfer characteristics and the hydraulic behaviour of carbon dioxide in a horizontal tube are experimentally investigated in this study. Two heating methods, namely a direct current carrying heating and an electric heater heating, were used. However, because the former method has superior experimental accuracy, the data obtained using the former method are described and discussed.
