办公建筑高效制冷机房研究与实践
Research and practice of high-efficiency chiller plant rooms in office buildings
摘要：
公共建筑空调系统能耗占建筑运行总能耗的40%～60%,研究并推广高效制冷机房技术是建筑行业实现“双碳”战略的有效手段。目前国内外技术标准及工程案例更多关注的是高效制冷机房整体能效比(EER),对高效制冷机房EER的影响因素及提升技术策略研究较少。本文结合理论及工程案例,研究明确了高效制冷机房EER的影响因素及其相互关系,提出了包含冷水机组选型优化适配、能源梯级利用、输配系统优化、精细化监测与控制等技术策略,并详细介绍了中国海外大厦项目应用实例,旨在为同类项目提供参考,助力高效制冷机房技术在办公建筑中产业化应用。
Abstract：
The energy consumption of air conditioning systems in public buildings accounts for 40% to 60% of the total energy consumption of building operation, and the research and promotion of high-efficiency chiller plant room technology is an effective measure for the construction industry to realize the “dual-carbon” strategy. At present, no matter domestic or foreign technical standards and engineering cases focus more on the overall energy efficiency ratio(EER)of high-efficiency chiller plant rooms, and less on the influencing factors of high-efficiency chiller plant room design and improvement technical strategies. Based on theories and engineering cases, this paper clarifies the influencing factors and their interrelationships of EER in high-efficiency chiller plant rooms, puts forward technical strategies including optimization and adaptation of chiller selection, gradient utilization of energy, optimization of transmission and distribution systems, and fine monitoring and control, and presents in detail the application examples of the China Overseas Building project, aiming to provide references for the same kind of projects, assisting industrialized application of high-efficiency chiller plant room technology in office buildings.
