摘要

R152a（ODP=0，GWP=124）对环境友好，热力性能完善，而吸收剂三乙二醇二甲醚（DMETrEG）沸点较高，毒性较弱，对较多制冷剂都有很好的溶解能力。因此，R152a与DMETrEG的二元混合物是一种具有潜在应用价值的吸收制冷工质对。采用气液双循环法，实验研究了R152a+DMETrEG在293.15~353.15 K温度范围内的汽液相平衡特性；分别采用NRTL模型和Wilson模型对测得的汽液相平衡（VLE）数据关联对比。实验结果与关联结果具有良好的一致性，NRTL模型拟合计算结果与实验结果的平均相对偏差为1.80%，而Wilson模型拟合计算结果与实验结果的平均相对偏差为1.83%。当混合溶液中R152a摩尔分数大于0.8时，R152a活度系数接近1，混合溶液可近似视为理想溶液。

Abstract

R152a (ODP=0

GWP=124) is environmentally friendly and has good thermal performance. The absorbent

triethylene glycol dimethyl ether (DMETrEG)

is less toxic

has high boiling temperature and good dissolution ability for more refrigerants. Therefore

the mixture of R152a and DMETrEG is considered as a potential absorption working pair. The vapor-liquid equilibrium(VLE) of R152a+DMETrEG in the temperature range of 293.15-353.15 K was studied by gas-liquid double-cycle method. NRTL model and Wilson model were used to correlate the experimental results. The results were in good agreement with the correlated results. The average relative deviation between the calculated results and the experimental results is 1.80% for NRTL model

and the average deviation between the calculated results and the experimental results is 1.83% for Wilson model. When mole faction of R152a in the solution of R152a and DMETrEG is larger than 0.8

activity coefficient of R152a is close to 1

therefore

this solution can be considered as an ideal solution approximately.
