Summary

Refrigeration and air conditioning systems consume about 17% of the global electricity generation. In addition, global efforts are put toward phasing out high GWP refrigerants with sometime contradictory results on the energy consumption leading to a systemic analysis of the environmental impact. Efforts to put in place to reduce this consumption must be first directed towards improving the compressor’s performance. Scroll and rotary compressors are widely used in small refrigeration systems and in air/air air conditioners. They have reached a high isentropic and volumetric performance with a continuous improvement. The oil charge in the crankshaft is specified by the manufacturer in a conservative way considering large circuits and the risk of bad oil return. In this paper an experimental analysis on the oil charge impact on a small capacity water chiller coefficient of performance is performed. The analysis of the experimental results shows an important increase in electricity consumption when the oil charge increases.
