Analysis on suitable operation conditions for public buildings using open-type cooling tower in transition season
摘要：
为评价冷却塔在过渡季节或冬季非额定工况条件下的热湿交换性能，基于冷却塔的基本热湿交换原理，以开式横流湿式冷却塔为研究对象，重点分析了室外空气湿球温度ts1、冷却塔进口水温tw1及水气比μ等因素变化对冷却塔全年运行热湿交换性能以及冷却塔冷却能力偏离额定工况的影响规律；并分析讨论了北京、南京、西安、重庆地区冷却塔过渡季节（冬季）供冷运行的适宜条件。
Abstract：
To evaluate the heat and moisture transfer performance of cooling tower objectively in the non-full rated operating state in transition season or winter, takes an open-type cross-flow wet cooling tower as research object based on the basic theory of heat and moisture transfer for cooling tower. Analyses the effects of outdoor wet-bulb temperature, inlet water temperature of cooling tower and water-air ratio on the heat and moisture transfer performance of cooling tower all year round and the characteristic of cooling capacity deviating from rated working condition. Discusses the suitable operation conditions of cooling tower in Beijing, Nanjing, Xi’an and Chongqing in transition season or winter.
