大型商业综合体空调系统节能诊断与调试优化

Energy-Saving Diagnosis and Commission of HVACs in Large Commercial Buildings

大型商业综合体空调系统节能优化是实现项目节能减排、降低运行费用、增加项目利润的重要途径。研究结果表明,在开展空调系统的节能诊断时,首先需要对空调系统各关键设备和系统的实际运行性能进行现场测试,结合运行数据,总结系统存在的典型问题,从而有针对性地给出节能优化方案,逐步提升空调系统运行能力,实现节能减排的作用。以我国北方地区一座大型商业综合体为例,对其空调系统现场诊断后进行详细地分析和研究,总结空调系统各关键设备和系统存在的典型问题,并有针对性地开展现场调适优化或提出节能改造建议,为同类项目提出参考建议。

Optimization of HVACs in commercial complex buildings is the main method to save energy,lower the running fee,as well as improve profit.The results show that it is necessary to conduct field tests on the practical running performance of each key equipment and system in the whole air conditioning system.And the typical problems of the system are summarized by combining with the running data so as to give a targeted energy-saving optimization scheme,gradually improving the running performance of the air conditioning system.Only in this way can we gain the benefits of energy conservation and greenhouse reductions.Therefore,this paper focused on the energy-saving diagnosis and commissioning of HVACs in a large commercial building in northern China.Based on field test results and analysis,the common problems and specific problems of typical devices and systems are identified and summarized.Then aimed at these typical problems,a commissioning method is proposed to optimize the energy efficiency of HVACs.
