| Abstract | The study presents an experimental investigation of the reduction of energy consumption. in a refrigeration system (water cooler) employing a passive evaporative cooling device (PECD). The PECD is placed on the top of compressor of water cooler to cool the compressor. Under of fixed indoor air condition (30 °C; 67% (relative humidity), the performance of the water cooler before and after PECD installation was compared. A decrease in power consumption of the unit is observed, with concomitant increases in coefficient of performance (COP). In addition, results obtained show that up to 17% increase in COP, and a 2.3% decrease in power consumption can be achieved by employing PECD. Additionally, the COP was found to increase by about 5.48% for every 1 °C drop in refrigerant condensing temperature
