Résumé
The current line sizing rules reported in the ASHRAE Handbook Refrigeration have limited consideration of the effects of oil in the system. With the increasing development of variable-speed systems as well as future use of newer HFO refrigerants, there is a need in the industry for upgrading the line sizing recommendations to more accurately consider the effects of oil retention. To study this issue in detail, a test setup has been built to measure oil retention in horizontal and vertical lines of different diameters at different refrigerant and oil flow conditions. Experimental results of oil retention for R1234ze(E) with POE32 in a typical air-conditioning suction line are compared with R32-POE32 in the paper. Based on the collected data, the final goal is to build a model that can predict oil retention in gas lines for some of the commonly used refrigerant-lubricant combinations in the HVAC&R industry.
