摘　　要：地下商业存在全年空调冷负荷,对冬季和过渡季空调采用冷却塔免费供冷技术,在经济上是否可行进行了研究。通过分析夏热冬暖地区全年湿球温度分布情况、冷水的供冷温度、新风供冷能力,提高冷却塔冬季和过渡季供冷小时数,得出冷却塔免费供冷的节能经济性。采用冷却塔免费供冷技术可以实现商业建筑运营降低空调运行成本的目的。The existence of a year-round air-conditioning cold load in ground floor commercial is investigated to determine whether it is economically feasible to use cooling tower free cooling technology for winter and transitional season air-conditioning.By analysing the yearround wet bulb temperature distribution,chilled water supply temperature and fresh air supply capacity in hot summer and warm winter regions,and increasing the number of cooling tower supply hours in winter and transitional seasons,the energy-saving economics of free cooling in cooling towers is derived.The use of cooling tower free cooling technology can achieve the purpose of commercial building operation to reduce air conditioning operating costs.
