Experimental studies on heat and mass transfer in tubular generator for R134a-DMF absorption refrigeration system

► R134a desorption from R134a-DMF mixture is investigated experimentally. ► Stainless steel concentric tubes are used as generator of absorption system. ► Heat and mass transfer parameters are analyzed. ► Effect of non dimensional parameters on generator performance is examined. ► Empirical correlations for Nusselt and Sherwood numbers are proposed.
