Summary

Due to the ongoing global phase-out of R22, which is still the most widely used refrigerant around the world, there is a need to replace this refrigerant in many different applications. This paper focuses on a thorough evaluation of the R22 replacement options for medium-temperature refrigeration applications. It includes a thermodynamic analysis, comparison of heat transfer and pressure drop characteristics, system performance comparisons using a validated detailed system model, safety issues, and determination of the environmental impact of refrigerant selection. Three potential alternatives to the R22 were studied: two HFCs (404A and R410A) and one HC (R290). An HFC refrigerant, R410A, is shown to be an efficient and environmentally acceptable option to replace R22 in medium temperature applications.
