Application of evaporative cooling and mechanical refrigeration combined air conditioning unit to Baoji Natatorium

Presents three kinds of common evaporative cooling and mechanical refrigeration combined air conditioning systems. Tests the operation performance of the evaporative cooling and mechanical refrigeration combined air conditioning unit for the audience area of Baoji Natatorium. Corrects the problems found in the test. The rectification results show that the mean efficiency of indirect evaporative cooling and direct evaporative cooling are about 61.4% and 82.5% respectively, and the temperature drop is about 9.5 ℃ when indirect-direct evaporative cooling system is running lonely, which reducing the running time of mechanical refrigeration, and the energy saving effect is remarkable.
