Prof. Baomin Dai suggested in 2018 that the use of zeotropic mixtures with high
glide could provide energy improvements as refrigerants in dedicated mechanical subcooling systems for CO2 plants due to matching of temperature profiles between the evaporation of the refrigerant and the CO2 during the subcooling. This communication addresses
this hypothesis from a theoretical point of view, selecting refrigerant blends that could be
used in the subcooling system, and then presents the experimental evaluation of three mixtures in a real plant.
Experimental evaluation has been done using a water-to-water CO2 transcritical refrigeration
plant at three heat rejection levels for an evaporation level of -10 ºC. The work will compare the
energy results and highlight the operation of the main components of the cycle. [-]
