Variable speed hermetic reciprocating compressors for domestic refrigerators

This article describes the results of a both theoretical and experimental investigation of the performance of variable speed hermetic reciprocating compressors for domestic refrigerators. The investigation was performed as a part of a larger research project with the objective of reducing the energy consumption of domestic refrigerators by increasing the efficiency of the refrigeration system. The improvement of the system efficiency was to be obtained by introducing continuous operation and use variable speed compressors for controlling the capacity of the refrigeration system. It was the aim of the project to double the efficiency of the refrigeration system and thereby reduce the energy consumption of the refrigerator by 50% compared to a standard refrigerator available on the market to day.
