蒸发冷却与机械制冷复合空调在中湿度地区的运行模式研究
Operating modes of evaporative cooling assisting to mechanical refrigerating air conditioning in mid-humid region
摘要：
分析了在中湿度地区夏季间接蒸发冷却与机械制冷联合使用中，间接蒸发冷却对室外空气先预冷后与回风混合以及先与回风混合再预冷对机组整体的影响，并结合工程实例，从风系统平衡、热湿平衡及能耗方面比较了两者的优劣。研究了过渡季节及冬季的运行模式，为蒸发冷却与机械制冷复合空调在中湿度地区全年空调运行处理模式优化提供了理论和实践依据。

Abstract：
Analyses the effect of indirect evaporative cooling with pre-cooling before mixing mode and mixing before pre-cooling mode to units, and with an engineering example, compares their advantages and disadvantages through the air system balance, heat and moisture balance, and energy consumption. Analyses the operating mode in winter and transition seasons, providing theoretical and practical basis for the optimization of annual operating modes.
