在《公共建筑节能设计标准》(GB50189-2005)和《天津市公共建筑节能设计标准》(DB29-153-2005)中,都明确指出“对于冬季或过渡季有供冷需求的建筑,技术经济分析合理时,应考虑利用冷却塔提供空调冷水的可能”。实际应用中,由于目前还没有比较明确的设计技术措施,所以各种设计方法和概念差异较大。本文结合由我院设计的天津某工程实例,从冷却塔免费供冷系统设计和运行管理角度进行了总结与分析,供大家在今后的设计实践中参考。
In the “Environmental Energy Efficiency Design Standards for Public Buildings” (GB50189-2005) and the “Tianjin Public Building Energy Efficiency Design Standards” (DB29-153-2005), it is clearly stated that "buildings with cooling demand for the winter or the transition season, technology When the economic analysis is reasonable, the possibility of using cooling towers to provide cold water for air conditioning should be considered. In practical applications, various design methods and concepts are quite different because there are no clear design and technical measures. This article combined with an engineering example designed by our institute in Tianjin, from the cooling tower free cooling system design and operation management point of view for the summary and analysis, for everyone to refer to in the future design practice.
