Reduction in the power consumption of household refrigerators by using variable speed compressors.

Author(s) : BINNEBERG P., KRAUS E., QUACK H.

Summary

Improvements in insulation, compressor efficiency and optimization of the refrigeration charge have reduced energy consumption significantly in recent years. Still more power can be saved by converting the capacity control strategy from compressor on/off cycling to a variable speed running mode. This control strategy leads to a reduction in the average speed of the compressor and fewer stops (periodic defrosting of the evaporator). Numerical simulation showed that this kind of operation can lead to energy savings of up to 30% due to: smaller friction losses in the compressor, higher evaporation temperature, lower condensing temperature and a reduction in losses associated with the pressure equalization on compressor stops.
