西安市公共建筑空调系统调查与节能分析

Investigation on Air-conditioning Systems and Related Energy-saving Analysis for Public Buildings in Xi'an

调查了西安市15幢公共建筑的空调系统,调查内容包括:冷源方式、水系统方式、末端方式及相应的控制策略。调查结果显示水系统主要为一次泵定流量系统,分析了一次泵变流量系统应用过程中出现的问题。分析了不同建筑不同末端控制水平,总结了冷源运行调节方式。最后,针对西安市现状,提出了相应的节能改造建议。

The cold source,water system,air-conditioning terminals and respective control methods on 13 public buildings in Xi＇an are investigated.The results indicate that most of water systems utilize the primary pump constant-volume system.The applied problems are ana lyzed for the variable primary flow system.And the control level of different air-conditioning terminals of various buildings is analyzed with the summary on cold source operation,finally providing the energy-saving improvement suggestion respectively.
