Summary

The performance of quatemionic refrigerant mixtures, R34Sfa/R600a/R508b/R14, in Linde-Hampson refrigeration cycle was experimentally investigated. To get the lowest operation temperature, the components of refrigerant mixtures were optimized. The influence of ambient temperature on system operational performance was analyzed. It is shown that the lowest system operation temperature could reach from -45°C to -85°C when mixing the four refrigerant components at different species ratio, If the proportion of the refrigerant mixtures charged is R24Sfa:R600a:RS08b:RI4=0.45:0.3:0.18:0.07, the operating temperature of the system can reach -85°C when the ambient temperature is 35°C. With the same refrigerant mixtures, the system temperature can reach -89.3°C if the ambient temperature decreases from 35°C to 5°C.
