Abstract

In this work, new thermodynamic models for refrigerant mixtures are provided for the binary pairs R-1234yf/134a, R-1234yf/1234ze(E), and R-134a/1234ze(E) based on new reference measurements of speed of sound, density, and bubble-point pressures. Fitting the very accurate liquid-phase speed of sound and density data reproduces the bubble-point pressures to within close to their uncertainty, yielding deviations in density less than 0.1% and speed of sound deviations less than 1% (and less than 0.1% for R-1234yf/134a). Models are also presented for the binary pairs R-125/1234yf, R-1234ze(E)/227ea, and R-1234yf/152a based solely on bubble-point measurements.

制冷剂R-1234yf/134a、R-1234yf/1234ze（E）和R-134a/1234ze（E

本文基于声速、密度和泡点压力的新参考测量值，为R-1234yf/134a、R-1234yf/1234ze(E)和R-134a/1234ze(E)二元制冷剂对提供了新的制冷剂混合热力学模型。拟合非常精确的液相声速和密度数据可再现气泡点压力，接近其不确定度，密度偏差小于0.1%，声速偏差小于1% (R-1234yf/134a小于0.1%)。本文还提出了仅基于气泡点测量的R-125/1234yf、R-1234ze(E)/227ea和R-1234yf/152a双星的模型。

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.
