“…Experimental measurements of thermal conductivity have increased by 300% in the last 4 years: while only 3 working fluids were studied in 2018, this number has now increased to 9, including R1234ze(E), R1234yf, R1233zd(E), R1234ze(Z), R1336mzz(Z), R1224yd(Z), R1243zf, R1336mzz(E) and RE356mmz. For all these [12], 66 data points for the compressed liquid (in the ranges T = 317 K to 416 K and P = 1.0 to 4.0 MPa, declared uncertainty: max 2.1%), and 46 for the superheated vapor (T = 376 K to 453 K, P = 0.2 to 1.5 MPa, declared uncertainty: max 2.3%). Deviations from REFPROP reference values are AAD% = 4.49 and MAD% = 8.58.…”

Thermophysical Properties of Low GWP Refrigerants: An Update

et al. 2023

In the last decades, the industry of HVAC&R has faced continuous changes trying to identify environmentally friendly refrigerants for the numerous applications of the sector. However, the amount of low GWP fluids still available as potential refrigerants is limited to some natural fluids and, among synthetic chemicals, to hydrofluoroolefins (HFO). The knowledge of the thermophysical properties of these compounds and the evaluation of their energy efficiency in experimental apparatuses is essential to properly address the selection of the most suitable fluids. However, regarding the wide majority of HFOs, the information on the thermophysical properties, especially for the blends, are still scarce and require further research. In this work, an analysis of the possible substitutes and the available experimental data sets on their thermophysical properties was carried out to find out for which fluids further studies are needed to obtain an accurate representation of their thermophysical properties. Specifically, for 21 pure refrigerants, an overview of the thermodynamic (critical point, psat, PVT, heat capacity and speed of sound) and transport properties (λ, μ, σ) data published in the peer reviewed literature was provided. In addition, a more comprehensive analysis was carried out for four fluids (R1243zf, R1233zd(E), R1336mzz(Z), and R1224yd(Z)), for which major efforts have been made in the last 4 years to investigate the above thermophysical properties. Although an increasing amount of data sets on thermophysical properties have been compiled in recent years, the present study indicates that research efforts are still needed, especially on transport properties, as only 4 of the fluids of interest for the present research have been fully investigated (R1234yf, R1234ze(E), R1233zd(E), R1243zf), while other 4 (R1234ze(Z), R1336mzz(Z), R1224yd(Z), R1336mzz(E)) have been almost completely characterised.

Jahangir Alam et al 17 summarized these basic physical property data on a list showing in the Table 1 Thermodynamic properties of the alternative refrigerant such as saturated vapor pressure and gaseous pvT properties are essential for predicting performance of the refrigeration cycle and designing the optimal compositions. But there are only a few research works on these fundamental properties of HFE-356 mmz, and it is difficult to develop the equation of state of the HFE-356 mmz because of the limited experimental data.…”

As one of the most promising alternative refrigerants, 1,1,1,3,3,3-hexafluoro-2-methoxypropane (HFE-356 mmz) is considered to have the potential to be applied in a high temperature heat pump and the organic Rankine cycle. The gaseous pvT properties of HFE-356 mmz were measured using the isochoric method in the temperature range from 333.068 K to 451.226 K, the pressure range from 104.9 to 1997.3 kPa, and the density range from 75.0 mol•m −3 to 882.0 mol•m −3 . The threeterm truncated virial equation of state for gaseous HFE-356 mmz was also fitted based on the experimental data.

“…Thermophysical properties of a working fluid to be used in the ORC represent an indispensable information for the evaluation of the performance of the thermodynamic cycle. Some researchers previously reported experimental data of some thermophysical properties of HFE-356mmz; for example, Sako et al [5] measured the critical properties and the normal boiling point, Alam et al [6] measured the thermal conductivity and the kinematic viscosity, and Chen et al [7] measured the pressure-volume-temperature (PVT) relation in the vapor phase.…”

Thermophysical properties of HFE-356mmz in the vapor phase were measured by means of an acoustic-microwave resonance method. HFE-356mmz, which is 1,1,1,3,3,3-hexafluoro-2-methoxypropane in chemical name, is expected to be used as a working fluid with low global warming potential for the Organic Rankine cycle (ORC). The sound velocity and dielectric permittivity were simultaneously measured by using a cylindrical acoustic-microwave resonator. The sound velocity data were analyzed to obtain the ideal-gas heat capacity at constant pressure. The integral of the ideal-gas heat capacity as a function of temperature derives the ideal-gas enthalpy, which is a fundamental and important energy property to simulate the thermodynamic cycle. Similarly, the analysis of the dielectric permittivity data leads to information on the ideal-gas molar polarizability, dipole moment, and density. The acquired thermophysical properties of HFE-356mmz were compared to those of R-245fa and n-pentane, which are the existing working fluids for the ORC system, to prospect a feasibility of HFE-356mmz as their alternative.
