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.Air Conditioning and Refrigeration Center Project 3
