Résumé

The study is part of an experimental project investigating new methods to improve the energy efficiency of refrigeration systems. Experiments were conducted on a water-based refrigeration test bench system utilizing a common 3.73 kW and 1750-RPM semi-hermetic compressor and very precise instrumentation. The capacity of the system's critical components was determined to be within a relative error of 3.65% or less. The transient phenomena that occur during cycling of the system were studied in detail and the drawbacks of the start-up procedure known as pump down cycle were demonstrated. The effects of the condensing pressure and the degree of superheat on the system performance under steady state conditions were also studied. It has been demonstrated that at low condensing pressure, corresponding to a moderate Canadian winter climate, the performance of the system can be significantly higher than under standard operating conditions.
