Pentaerythritol esters (PECs) act as the main precursors in polyol ester (POE) lubricants.
The solubility of low global warming potential (GWP) refrigerants in linear chained PECs …

R32 has been widely used in room air-conditioners, and its dissolution in lubricating oil can
significantly affect the air-conditioner performance. The dissolved mass of R32 is determined …

Experiments were carried out to determine rates of absorption of R-1234yf through the free
surface of an initially stagnant layer of lubricant POE ISO VG 10 in a closed system. Rayleigh …

Propane (R290) has excellent thermophysical properties and development potential. The
dynamic characteristics of R290 rotary compressors and room air conditioners have been …

Refrigerant inevitably dissolves into lubricating oil in the heat pump compressor, and it will
precipitate from the lubricating oil with the decrease of refrigerant pressure. The precipitation …

Abstract 2, 3, 3, 3-tetrafluoroprop-1-ene (R1234yf) and isobutane (R600a) regarded as
green refrigerants have received much attention in the refrigeration industry. Phase …

Isobutane (R600a) is widely used in small capacity refrigeration equipment, especially
domestic refrigerator. Knowledge of refrigerant absorption in lubricant oil is one of the …

Natural refrigerant propane has a saturated-liquid density that is only about half that of HFC
refrigerants. Compared with traditional refrigerants, the absorption/desorption characteristics …

The solubilities of isobutane (R600a) in pentaerythritol tetrapentanoate (PEC5) and in
pentaerythritol tetraheptanoate (PEC7) between (293.15 and 348.15) K have been …

In this work, the mutual diffusivities of difluoromethane (R32) and 2, 3, 3, 3-
Tetrafluoropropylene (R1234yf) dissolved in Polyalkylene glycol (PAG) lubricant were …
