Consolidated experimental heat and mass transfer database for a reduced scale evaporative condenser

•An experimental investigation in a small scale evaporative condenser is presented.•Results are ready to be used by researchers on refrigeration.•The experimental rig is built according to the ANSI/ASHRAE 64–1995 standard.•Database with 40 samples were built under stationary conditions.•Heat rejection is constant and 3 relevant parameters are kept controlled.

This work reports an experimental investigation on the heat and mass transfer phenomena observed in a reduced scale evaporative condenser, operated under laboratory controlled conditions. Experimental results are organized on sequences of consolidated samples, ready to be used for analysis and simulation by researches on refrigeration and transport phenomena. Heat rejection is kept constant for each of the 40 samples as a function of the inlet air temperature, volumetric flow rate and the spray water mass flow rate. The inlet wet bulb temperature showed to be the most significant parameter, leading to a predictive model of the mean rejected heat, with a correlation coefficient R2 of 79.3%, and a maximum error of 13.28%.
