Abstract
The disposition of fluorine and hydrogen atoms in the double bond or on opposite sides of this double bond that obeys the CahnIngoldPrelog rules (precedence rule) is described. To obtain thermodynamic properties of refrigerants the experimental data of which are not available, Brown et al. offered to use the PengRobinson equation realized in REFPROР 8.0 program. lg P-h and T-S diagrams for HFO refrigerants R1234yf, R1234ze(E) and HFC refrigerants R407С, R134a, R404А are cited as an example. Thermophysical characteristics of R1234yf, R1234ze(E) are compared with those of R134a and R1233zd(E), R1336mzz(Z). The possibility to use the refrigerants of HFO class in refrigeration engineering and air conditioning systems to replace R134a is considered. It is noted that the cost of HFO refrigerants is rather high and today their offer in the refrigeration market is limited.
