2,Gide in Evaporators-Flooded EVAP gDo Consideration Consider two of the frontrunners to replace R-22, R-407C and R-410A. Both are zeotropes. However, the glide for R-407C is 8° while the glide for r-4l0 A is only 1°C The high glide for R-407C means it can be practically used only in DX systems, which limits the overall system efficiency nat can be expected when using it. R-410A can be used in flooded systems, so even though it components including oppressors(it operates at a significantly higher pressure),it the common choice for redesigned refrigeration systems compressor.

The heat from the chilled water in the tubes boils the refrigerant, which floats to the top of the shell. The inlet of the compressor draws in the gaseous refrigerant. The process is very similar to water boiling in a pot on a stove.The issue with zeotropic refrigerants that have significant glides is that as the refrigerant fractionates, the compound with the lowest boiling point floats to the top first and enters the compressor. Therelative mass ratios are not maintained. 3,Glide Consideration Consider two of the frontrunners to replace R-22, R-407C and R-410A. Both are zeotropes. However, the glide for R-407C is 8°C while the glide for R-410A is only 1°C. The high glide for R-407C means it can be practically used only in DX systems, which limits the overall system efficiency that can be expected when using it. R-410A can be used in flooded systems, so even though it requires complete redesign of all components including the compressors (it operates at a significantly higher pressure), it is the common choice for redesigned refrigeration systems. 4, Zeotropic Serviceability Initial and Final Concentrations at Different Locations Reduction in Performance After Leak/Recharge
