摘要：
The gas chromatography mass spectrometry method is used to analyze the components and the share of each component in POE22 and to study the phase equilibrium properties of the environmental refrigerant propane (R290) and polyol ester (POE) lubricant. Then the isochoric saturation method is used to measure the solubilities of R290 in POE22 at 278.15 - 348.15 K, and the NRTL model is used to correlate the experiment results. The results show that POE22 is mainly composed of four ester compounds and three additives, and the seven components accounts for 99.49% in POE22. The absolute average deviation and the maximum relative deviation between the calculated theoretical pressure value and the experimental pressure value are 0.565% and 2.934%, respectively. Moreover, no chemical reaction or immiscibility phenomenon between R290 and oil are found in the temperature range from 278.15 to 348.15 K. Experimental results are compared with the reported solubility of R290 in two mineral oils (ISO VG12 and NM100P), and it is found that POE oil is more suitable for R290. © 2020, Editorial Office of Journal of Xi'an Jiaotong University.
