Investigation of oil retention and pressure drop in suction lines using R134a with AB ISO 32
… mixture possesses the maximum viscosity in the suction line to compressor, due to the superheated vapor, and it is for this reason that studies are performed to evaluate oil retention and pressure drop in suction lines. The aim of the current work is to study the oil retention and pressure drop …

Oil retention and pressure drop of R1234yf and R134a with POE ISO 32 in suction lines
… and refrigerant has the highest viscosity in the suction line to the compressor due to which it has the highest potential for oil retention. R1234yf is a new alternative refrigerant of low global warming potential (GWP) which has been developed for automobile air conditioners as a drop-in …

Oil Retention and Pressure Drop in Horizontal and Vertical Suction Lines with R410A / POE ISO 32
… where some is retained in each component. The suction line to the compressor has the largest potential for oil retention. This paper presents results from an experimental apparatus that has been constructed to circulate POE (polyolester) oil and R410A at a controlled mass flux, OCR (oil in …

Investigation of oil retention and pressure drop in suction lines using R1234yf, R134a and R410A with POE ISO 100
… interest is studying the retention of oil at suction lines to the compressor, where conditions lead to a mixture that is rich in oil, consequently leading to high oil retention due to high mixture viscosity. The current work presents experimental data for oil retention and pressure drop in …

Effect of oil in circulation on automotive A/C component and system performance
… transfer, pressure drop over heat exchangers and suction lines, compressor work, as well as COP. In addition, infrared images of both evaporator and condenser are taken in each experiment. The results are then compared with two previous findings to have a more generalized conclusion on the OCR …
