A study on the evaporator of a CO2 refrigerant cycle: heat transfer coefficient characteristics and pressure drop on mixing CO2 and oil.

Author(s) : KATSUTA M., TAKEO N., KAMIMURA I., et al.

Summary

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.
