Abstract
The analysed alternatives are hydrocarbons, CO2 and HFC/HFO mixtures. The hydrocarbons would be a good alternative, but the required system components are not available. The HFC/HFO mixtures are the alternative with the available system components. The drop-in replacement test results with R448A refrigerant demonstrate significant performance degradation. At 25 °C ambient temperature the pull-down time increased by 24% and the power consumption increased by 9%. Also, due to the glide and lower evaporation pressure, the retrofitted system cannot reach the required evaporation temperatures.
