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。
In the combined use of summer indirect evaporative cooling and mechanical refrigeration in middle and humid areas, the influence of indirect evaporative cooling on the preheating of outdoor air after mixing with return air and before and after return air mixing and precooling were analyzed. Combined with the engineering examples , From the wind system balance, heat balance and energy consumption of both the pros and cons. The transitional season and winter operation mode were studied, which provided the theoretical and practical basis for the optimization of air-conditioning operation mode in the whole year in both medium-humidity and evaporative cooling.
