Abstract

Thermal mass effects, refrigerant dynamics, and interchanger transients are three factors affecting the transient and cycling performance of all refrigeration and air conditioning equipment. The effects of refrigerant dynamics, including refrigerant/oil solubility, off-cycle migration, and charge redistribution, were found to be the most important. These effects are quantified for a refrigerator instrumented with immersion thermocouples, pressure transducers, and microphones. The analytical methods, however, are applicable to other types of refrigeration and air conditioning systems, including those with capillary tube/suction line heat exchangers.
