摘要
据调研,我国大部分公共建筑空调制冷机房全年运行能效比仅为2.0~3.0,能效水平低下。随着国家住建部、发改委发布《城乡建设领域碳达峰实施方案》(建标[2022]53号),明确提出要加强空调等重点用能设备运行调试,提升设备能效,到2030年实现公共建筑机电系统总体能效在现有水平上提升10%^([1])。如何建设与运营高效空调制冷机房成为了当前研究的热点。采用理论研究、IT开发及示范应用相结合的方法,研究了高效空调制冷机房建设相关技术,并通过项目示范应用,将示范项目空调制冷机房系统年运行能效比提升至5.32,达到了现行团体标准《高效制冷机房技术规程》(T/CECS 1012-2022)规定的3级能效要求。结果表明,该技术可显著提升空调制冷机房运行能效水平,应进一步推广应用。
According to research,the annual energy efficiency ratio of air conditioning and refrigeration rooms in most public buildings in China is only 2.0-3.0,which is a low energy efficiency level.With the issuance of the Implementation Plan for Carbon Peaking in Urban and Rural Construction(JB No.53)by the Ministry of Housing and Urban-Rural Development and the National Development and Reform Commission,it is clearly proposed to strengthen the operation and debugging of key energy consuming equipment such as air conditioning,improve equipment energy efficiency,and achieve a 10%increase in the overall energy efficiency of public building electromechanical systems by 2030.How to build and operate efficient air conditioning and refrigeration rooms has become a hot research topic.Using a combination of theoretical research,IT development,and demonstration applications,the technology related to the construction of efficient air conditioning and refrigeration rooms was studied.Through project demonstration applications,the annual energy efficiency ratio of the demonstration project's air conditioning and refrigeration room system was increased to 5.32,meeting the 3-level energy efficiency requirements specified in the current group standard Technical Specification for High Efficiency Refrigeration Room(T/CECS 1012-2022).The results show that this technology can significantly improve the energy efficiency level of air conditioning and refrigeration room operation and should be further promoted in the future step by step.
