Measurement and correlation for phase equilibrium of HFO1234yf with three pentaerythritol esters from 293.15 K to 348.15 K

2,3,3,3-Tetrafluoroprop-1-ene (HFO1234yf) is recently recognized as a new generation refrigerant to replace R134a in automotive air-conditioning system and other refrigeration applications. The knowledge of phase equilibrium property for refrigerant with lubricant oil is therefore interested in these systems. A systematic research program on the phase equilibrium of HFO1234yf with lubricant oils has been carried out in our laboratory, and the...
