Thermodynamic optimization of evaporators with zeotropic refrigerant mixtures.

Author(s) : RAGAZZI F., PEDERSEN C. O.

Summary

Zeotropic (or nonazeotropic) refrigerant blends are attractive replacements because of their low ozone depletion potential and global warming potential values, as well as promising thermodynamic characteristics. Zeotropes experience a variable temperature glide during isobaric phase changes. This, combined with changes in evaporator design, can lead to a better match between the temperature glides of the refrigerant and the external fluid, reducing heat exchanger irreversibilities and increasing system performance. The purpose of the study was to investigate the effect of evaporator design on performance.
