Abstract:

Studying the thermophysical properties of new refrigerants is the basis of refrigerant substitution. Among the new environment-friendly HFO refrigerants, R1336mzz(E) has similar thermal properties to R245fa and is a promising alternative to R245fa in high temperature heat pumps and organic Rankine cycles. The liquid viscosity of R1336mzz(E) in the range of 278—333 K was measured by rotating capillary viscometer. Besides, we correlated the experimental data according to four liquid viscosity equations, and obtained the correlation equation between the viscosity of R1336mzz(E) and temperature. As a result, it illustrated that the modified nonlinear Andrade correlation equation had the highest correlation accuracy. Besides, its average absolute deviation (AAD) and maximum absolute deviation (MAD) were 0.170% and 0.311%, respectively. Based on the application prospect of R1336mzz(E) in high temperature heat pump, through the fitting of four viscosity correlations, the experimental data were extrapolated to the critical temperature (403.37 K). What's more, the modified nonlinear Andrade correlation extrapolation obtained the most reliable data according to the error analysis. Of course, it could be used as the viscosity data near the critical temperature of R1336mzz(E). We intended to provide basic data for the alternative application research of R1336mzz(E).

摘要:

研究新型制冷剂的热物理性质是制冷剂替代工作的基础。在新型环保HFO类制冷剂中,R1336mzz(E)因其与R245fa相似的热力学性质,在高温热泵和有机朗肯循环中有希望成为R245fa的替代制冷剂。采用旋转式毛细管黏度计,测量了278 ~ 333 K温度范围内R1336mzz(E)的液相黏度,并根据四种形式的液体黏度方程对实验数据进行拟合,得到R1336mzz(E)黏度与温度的关联式。结果表明,采用修正后的非线性Andrade关联式所关联的精度最高,其关联结果与实验结果之间平均绝对偏差(AAD)和最大绝对偏差(MAD)分别为0.170 %和0.311 %。基于R1336mzz(E)于高温热泵的应用前景,通过拟合所得的四种黏度关联式对实验数据进行至临界温度(403.37 K)的外推,根据误差分析,采用修正后的非线性Andrade关联式外推得到的数据最可靠,可作为R1336mzz(E)临界温度附近的黏度数据。研究工作可以为R1336mzz(E)的替代应用研究提供基础数据。
