which is the loss coefficient caused by the partial resistance in the leakage hole, and its value depends on the leakage hole shape, usually between 0.6 and 0.99 [68,69]; k is the isentropic index; M is the kilo-molar mass of the gas, kg/kmol; R is the gas constant, kJ/(kmol·K...
R134a based mixtures due to the lower molar mass of R290 The two synthetic oils show a similar behaviour at low temperatures and a slight deviation at higher temperatures Study of the effect of water content on the binary diffusion coefficient in refrigeration oil/refrigerant mixtures Study of ...
The mixed refrigerant is mainly the mixture of hydrofluorocarbon and unsaturated olefin, which can be used to replace high GWP refrigerants such as R134a, R410A, R404A. The comparison of GWP and safety performance between the current used refrigerants and alternatives is shown in Table 2. It ...
