Water subcooling with liquid refrigerant overfeed.

Author(s) : FAUCHER G., ZEGAN D., PARADIS M. A.

Summary

Water chilling and supercooling in a double-pipe evaporator using Turbo B-II finned tubes with R22 refrigerant overfeed in counterflow were investigated. Steady flows of filtered water at Reynolds numbers ranging from 10460 to 41570 were cooled down to 0 deg C or supercooled to about -2 deg C for ice generation purposes. Heat flux densities of about 17 to 57.5 kilowatts per m2 were obtained without any evaporator freeze-up. The heat flux density was found to be independent of the refrigerant circulating rate, which was varied from 1.3 to 3.8, probably due to the special finned tube.
