多功能建筑空调系统能耗分析及优化设计 杨 天 郭海庆 翟晓强 王如竹 (上海交通大学机械与动力工程学院制冷与低温工程研究所，上海 200240) 摘 要 近年来，随着我国人民生活水平的不断提高，社会能耗不断上升。同时石油等自然资源也日益紧 缺，开采成本也越来越高，如何采取有效的措施降低能耗的问题就日渐突出，而建筑能耗中的空调系统能 耗又占了社会总能耗中相当大部分。如今人们越来越关注室内空调系统能否在保证良好的空气质量情况下 满足热舒适的要求，并降低能源消耗。与此同时，为了达到这些目的，采用不同控制策略的空调系统也应 运而生，有 VAV 系统，VWV 系统，热湿独立处理系统等等。然而如果不进行合理的能耗分析，不采用合适 的控制策略，采用这些系统依然不能有效达到目的。本课题来源于 2007 ASHRAE 空调系统设计竞赛，拟以 美国曼哈顿地区一建筑为例，在满足 ASHRAE 标准的情况下，对该建筑进行空调系统设计以达到满足热舒 适的要求，同时降低能耗和系统成本。 关键词 能耗分析；建筑分区；控制策略； ENERGY ANALYSIS AND HVAC SYSTEM DESIGN FOR A MULTI-FUNCTIONAL BUILDING RENOVATION Yang Tian Guo Haiqing Zhai Xiaoqiang Wang Ruzhu (Institute of Refrigeration and Cryogenics, Shanghai Jiaotong University, Shanghai 200240 ） Abstract As people spend more time indoors, heating, ventilation and air-conditioning (HVAC) systems that provide high indoor air quality and thermal comfort become very important. With the soaring price of oil, it is more than any time that our society concerns about the energy consumption in our buildings, of which the HVAC system’s energy consumption takes up the most proportion. In return, there come various conditioning strategies to meet the demands of our society, such as VAV (Variable Air Volume) system, VWV (Variable Water Volume) system, independent control humidity and temperature system and etc. All of these bring various alternatives for us in our HVAC system design. However, without proper and precise controlling strategy, these conditioning methods may turn out to waste energy rather than save it. This topic originated from ASHRAE 2007 student design competition. We mean to design a proper HVAC system for an existing building in Manhattan, New York. It aims at meetin
