In the search for substitutes for high global warming potential (GWP) refrigerants, measurements of thermodynamic properties for refrigerants belonging to new halogenated olefins group (HFO) is of strict actuality, due to their GWP, close to that of natural refrigerants, and the lack of information on their properties. One of the most interesting HFOs is cis-1-chloro-2,3,3,3-tetrafluoropropene (R1224yd(Z)), suitable, for its relatively high NBP (287.15 K) and its low vapour pressure, to be used in applications such as Organic Rankine Cycles (ORC), industrial high temperature heat pumps or centrifugal chillers. The paper presents 90 experimental compressed liquid density data for R1224yd(Z) in a range of temperatures and pressures varying from 283.15 K and 363.15 K and from close to saturation pressure up to 35 MPa, respectively. The data were measured by means of a vibrating tube densimeter at isothermal conditions. By extrapolating the isothermal compressed liquid density data at the saturated pressure, 10 saturated liquid density values have also been obtained. A Tait correlation for the compressed liquid density data and a dedicated correlation for the saturated liquid density are presented. Both correlations well represent the experimental data, with a percentage absolute average deviation (AAD%) of 0.1% in both cases. Experimental liquid density data have been compared to literature through the most updated version of the fundamental equation of state proposed by (Akasaka et al., 2017). The equation shows a very good agreement with the present data, considering that most of the data are in the extrapolation areas of the equation.

在寻找具有高全球变暖潜能值（GWP）制冷剂的替代品时，由于它们的GWP值接近自然制冷剂，因此属于新卤代烯烃类（HFO）的制冷剂的热力学性质的测量具有严格的现实性。有关其属性的信息。最有趣的HFO之一是顺式-1-氯-2,3,3,3,3-四氟丙烯（R1224yd（Z））适合用于相对较高的NBP（287.15 K）和低蒸气压，可用于有机朗肯循环（ORC）等应用中），工业高温热泵或离心式冷却器。本文介绍了R1224yd（Z）的90种实验压缩液体密度数据，其温度和压力范围分别为283.15 K和363.15 K，以及接近饱和压力（最高35 MPa）。数据通过等温条件下的振动管密度计测量。通过外推饱和压力下的等温压缩液体密度数据，还获得了10个饱和液体密度值。给出了压缩液体密度数据的泰特相关性和饱和液体密度的专用相关性。两种相关性都很好地代表了实验数据，两种情况下的绝对平均偏差百分比（AAD％）为0.1％。通过（Akasaka等人，2017）提出的状态基本方程的最新版本，将实验液体密度数据与文献进行了比较。考虑到大多数数据都在方程的外推区域中，该方程与当前数据非常吻合。
