本文介绍了福州海峡国际会展中心工程的暖通节能设计思路和方案。在设计过程中,随着项目使用功能的不断调整,笔者采用建筑环境与系统模拟分析软件对该工程的负荷特性、系统形式和送风方式等进行了模拟分析,并对不同的系统冷热源形式进行了比较,最终确定为冰蓄冷+常规电制冷+地下水源热泵组成的复合式能源系统。另外,针对本工程中的大型空调水系统,采用了大温差、分区域二次泵和合理的水力平衡等输送系统的节能技术。所得结论为:在暖通系统设计中,打造绿色建筑的正确途径是提倡因地制宜、强调经济适用,运用先进的模拟分析手段,采用适宜的节能技术,避免盲目追求新技术。
This article introduces the design ideas and programs of HVAC for Fuzhou Strait International Convention and Exhibition Center. In the process of design, with the continuous adjustment of the project’s using function, the author carried out the simulation analysis on the load characteristics, system form and air supply mode of the project by using the building environment and system simulation analysis software, Forms were compared and finally identified as ice storage + conventional electric + groundwater source heat pump heat pump composed of composite energy systems. In addition, for the large-scale air-conditioning water system in this project, energy-saving technologies of transmission system such as large temperature difference, sub-area secondary pumps and reasonable hydraulic balance are adopted. The conclusion is: In the design of HVAC system, the correct way to build green building is to advocate measures to local conditions, emphasize economy, apply advanced simulation and analysis methods, and adopt appropriate energy-saving technologies to avoid blind pursuit of new technologies.
