RP-1394 -- Study of Carbon Dioxide Condensation in Chevron Plate Exchangers PDF

Global warming concerns are gaining momentum in the twenty-first century and as such, environmentally friendly refrigerants are quickly becoming a necessity rather than just an interesting topic to speculate about for the future. Carbon dioxide, CO2 or R-744, is a top contender, as instigated in the Montreal protocol, to phase out the use of ozone depleting chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCFC) refrigerants, especially in low temperature applications.

This study focused on the condensation of carbon dioxide in brazed plate heat exchangers. It is the first ASHRAE sponsored project to better understand the physics of the condensing phenomenon of carbon dioxide in heat exchangers consisting of complex inner geometries.
