摘要
针对蒸发式冷气机用于通信机房在冬季不能很好地控制湿度，提出了直接蒸发冷却空调系统的优化方案和运行模式。将全年的室外气象参数划分成5个区域，根据室外气象参数采取不同的空调系统运行模式。以ASHRAETC9．9所推荐运行区为控制目标，评估了通信机房采用优化方案的节能潜力，计算了全国31个省会城市可运行直接蒸发冷却空调系统的时间。结果表明：广州、南宁、海口等城市的节能潜力较低，运行时间不足全年时长的40％，其中海口的节能潜力最低，只达到10．6％；节能潜力最高的城市为拉萨，达到82．3％；其他省会城市除郑州、昆明、西宁、兰州可达到60％以上之外，节能潜力均在40％～60％之间。
To solve problem that the direct evaporative air cooler applied to a telecommunication equipment room in winter cannot control humidity very well, presents an optimization scheme and its operation mode. Divides the whole year outdoor meteorological parameters into five regions, and adopts the different operation mode according to the parameters. Taking the ASHRAE TC 9.9 recomm, end operational area as the control target, evaluates the energy saving potential of the optimization mode, and calculates the running hours of the direct evaporative cooler for 31 provincial capital cities of China. The results show that the energy saving potential in Guangzhou, Nanning, Haikou are relatix/ely low, the running hours are less than 40% of the whole year, among that Haikou＇s is the minimum, only 10.6% and Lhasa is the maximum, up to 82.3%; expect for Zhengzhou, Kunming, Xining, Lanzhou can achieve above 60%, the energy saving potential of other provincial capital cities are between 40% to 60%.
