Abstract
An average R12 refrigerant correlation has been developed for the mass flux range of 25-100
kg/m2-s and the heat flux range of 2-10 kW/m2. Refrigerant mixtures of 80% R22/lO% R141b and 65%
R22/35% R123 have also been tested over asjrniJar range of conditions. Mixture heat transfer
coefficients have been detennined and correlations for each mixture pair are presented. The R221R141b
average correlation may have a strong dependence on changes in surface tension. The heat transfer
coefficient of R22JR141b compares well with that of R12. The heat transfer coefficient of R22/R123
severely under performs R12.
