Résumé

In vapour compression systems which use refrigerant as a working fluid, the oil is, also, commonly used for compressor lubrication. Since the presence of lubrication oil can change the characteristics and thermodynamic properties of refrigerant, the oil affects the heat transfer performance of heat exchanger to a large extent. In this paper, we focus on the effect of PVE oil experimentally on heat transfer performance of the fin-tube heat exchangers which use R410A as a refrigerant. To evaluate the heat transfer performance, the refrigerant to air type test facility chamber has been used. Round tube heat exchanger with grooved tubes has been tested while according to the oil mass fraction variation from nearly zero to almost 2 wt%. It was found that the low level of oil mass fraction has an obvious effect on heat transfer performance, while the high level seems no significant influence. The influence of the oil mass fraction to heat transfer performance, however, is different between evaporation and condensation.
