In this paper

the application feasibility of evaporative condenser in protective engineering is analyzed. The influence of air volume and water spraying density on heat and mass transfer performance was investigated in the experimental platform designed by the authors. It is found that refrigerating capacity and heat transfer capacity were almost unchanged

heat transfer capacity of unit air volume and total consumption were increased

and ECR was reduced

with the decrease of the air volume when spraying density was constant. Refrigerating capacity

energy consumption of compressor and ECR were changed in the same way with the spraying density under different air volume. The best air volume and spraying density are 2000 m3/h and 0.025 kg/(m?s).
