Applicability and performance optimization of cooling tower cooling systems in public buildings(2): Climate zone differences and performance optimization
摘要:
引入了冷却塔供冷运行时间比、空调冷源系统综合性能系数作为主要评价指标,基于广州(夏热冬暖地区)、上海(夏热冬冷地区)、北京(寒冷地区)、乌鲁木齐(严寒地区)的典型气象年参数中过渡季及冬季的数据,分析了办公、商业类建筑的冷却塔供冷系统性能,进一步分析了冷却水系统侧的供回水温度、冷却塔气水比对冷源系统综合性能系数的影响,并探究了不同气候区各参数的最优组合。
Abstract:
This paper introduces the cooling tower cooling operation time ratio and the comprehensive coefficient of performance of the air conditioning cold source system as the main evaluation indicators. Based on the transitional season and winter data from typical meteorological year parameters of Guangzhou (hot summer and warm winter zone), Shanghai (hot summer and cold winter zone), Beijing (cold zone), and Urumqi (severe cold zone), it analyses the performance of cooling tower cooling systems in office and commercial buildings. Furthermore, it examines the impact of the supply and return water temperature on the cooling water system side and the air-water ratio of the cooling tower on the comprehensive coefficient of performance of the cold source system, and explores the optimal combinations of various parameters in different climate zones.
Keywords:public building; cooling tower; cooling; climate zone; air-water ratio; operation time ratio; comprehensive coefficient of performance
