摘要
地铁车站通风空调系统的能耗占地铁车站总能耗的45%以上,因此如何有效降低通风空调系统能耗是车站节能的重点。通过对地铁通风空调系统进行系统地能耗分析,提出在空调系统设计阶段,采用优化系统布置、大温差送风的措施,具有较好的节能效果;运行阶段,通过采用通风空调系统中风机、水泵的变频技术,动态节能可达27%～78%。
The method for reducing energy consumption of the ventilation and air-conditioning systems is focused,because the energy consumption caused by ventilation and air-conditioning system is accounted for more than 45% of the total energy consumption in subway station.Trough the analysis,the measures of air supply between large temperature difference and adopting optimized system layout are proposed,which can make it possible for obtaining a good effect of energy-saving.Moreover,during operational phase,the dynamic energy-saving is up to 27% ～78% through using fans and water pump frequency conversion technology in ventilation and air-conditioning system.
