宝鸡游泳馆蒸发冷却-机械制冷空调系统应用探讨
Application of evaporative cooling and mechanical refrigeration combined air conditioning unit to Baoji Natatorium
摘要：
介绍了3种常见的蒸发冷却与机械制冷联合空调系统。实测了宝鸡市游泳馆观众区蒸发冷却-机械制冷联合空调机组的运行性能，针对测试中发现的问题进行了整改。整改后的测试结果表明：间接蒸发冷却平均效率为61.4%，直接蒸发冷却平均效率为82.5%；单独运行间接-直接蒸发冷却系统，平均温降为9.5 ℃，减少了机械制冷的运行时间，节能效果显著。
Abstract：
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.
