An evaluation of options for replacing HCFC-22 in commercial refrigeration systems.

Author(s) : SPATZ M. W., YANA-MOTTA S. F.

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. An HFC refrigerant, R410A, is shown to be an efficient and environmentally acceptable option to replace R22 in medium temperature applications.
