Abstract

For supporting future demands of lower temperature. environmental friendly low- temperature refrigerants must be studied and developed to replace halocarbon. Ethane. which is one of hydrocarbon compound. is an environmental friendly refrigerant because it has zero ODP and GWP ${\sim}$ 20[per 100yr]. On this study, two-stage cascade refrigeration system was utilized to investigate performance of ethane on the low-stage. By employing R22 at higher stages. energetic performance as well as operating condition of R22/R170 system is compared to R22/R23. At low stage evaporation pressure ranges from 1.10 to 2.74 bar, R22/R170 shows higher COP over R22/R23. Furthermore, at the same range evaporation temperature R22/R170 can reach lower temperature.
