The effect of vapour super-heating on hydrocarbon refrigerant condensation inside a brazed plate heat exchanger

This paper investigates the effect of vapour super-heating on hydrocarbon refrigerant 600a (Isobutane), 290 (Propane) and 1270 (Propylene) condensation inside a brazed plate heat exchanger.Vapour super-heating increases heat transfer coefficient with respect to saturated vapour, whereas no effect was observed on pressure drop.

HC-1270 shows super-heated vapour heat transfer coefficient 5% higher than HC-600a and 10–15% higher than HC-290 together with to

HC-1270 shows super-heated vapour heat transfer coefficient 5% higher than HC-600a and 10–15% higher than HC-290 together with total pressure drops 20–25% lower than HC-290 and 50–66% lower than HC-600a under the same mass flux.
