摘要

基于相应状态框架，建立了R-32/1234yf、R-32/1234ze(E)、R-1234ze(E)/227ea、R-1234yf/152a和R-125/1234yf制冷剂对的热力学模型。这些模型是基于密度、声速和相平衡的新测量，并结合文献中可用的数据。R-32/1234yf模型的数据覆盖范围最为全面，声速偏差在1%以内，密度偏差在0.1%以内，气泡和露点压力偏差在1%以内。其他混合通常具有更有限的数据可用性，但具有相似的拟合优度。

Mixture Model for Refrigerant Pairs R-32/1234yf, R-32/1234ze(E), R-1234ze(E)/227ea, R-1234yf/152a, and R-125/1234yf

In this work, thermodynamic models based on the corresponding states framework with departure terms are developed for the refrigerant pairs R-32/1234yf, R-32/1234ze(E), R-1234ze(E)/227ea, R-1234yf/152a, and R-125/1234yf. These models are based on new measurements of density, speed of sound, and phase equilibria, combined with the data available in the literature. The model for R-32/1234yf is most comprehensive in its data coverage, with speed of sound deviations within 1%, density deviations within 0.1%, and bubble- and dew-point pressure deviations within 1%. The other mixtures have generally more limited data availability but a similar goodness of fit.

期刊介绍： The Journal of Physical and Chemical Reference Data (JPCRD) is published by AIP Publishing for the U.S. Department of Commerce National Institute of Standards and Technology (NIST). The journal provides critically evaluated physical and chemical property data, fully documented as to the original sources and the criteria used for evaluation, preferably with uncertainty analysis. Critical reviews may also be included if they document a reference database, review the data situation in a field, review reference-quality measurement techniques, or review data evaluation methods.
