Résumé

In a refrigeration cycle, some of the oil circulates and resides in cycle components. The worst scenario of oil circulation in the cycle is where a large amount of oil is retained outside the compressor. The purpose of the study is to experimentally clarify oil retention and pressure drop characteristics due to the presence of oil in CO2 air-conditioning systems. In the study, an oil injection-extraction test method was adopted for CO2 air-conditioning systems with CO2 and PAG oil. The test facility is described. The oil retention volume in each component was determined. The oil retention test was performed on an evaporator, a gas cooler and in the suction line.
