摘要
通过对现有新风机组运行能耗的分析,提出了一种带旁通风道的新风机组。以成都地区某办公楼为例,根据室外空气干球温度、PM2.5浓度及室外空气比焓分布,研究了该种新风机组不同运行模式下全年运行能耗的变化。结果表明,仅旁通表冷器全年节能率为3.56%,仅旁通过滤器全年节能率为24.29%。研究结果可为新风机组节能设计提供方向,也可为新风系统设计提供新的思路。
Through the analysis of the operation energy consumption of the existing outdoor air units,a new outdoor air unit with by-pass ventilation ducts is proposed in this paper.Taking an office building in Chengdu as an example,based on the distribution of outdoor air dry bulb temperature,PM2.5 concentration,and outdoor air specific enthalpy,the change of annual operation energy consumption of the outdoor air unit under different operation modes is studied.The results show that the annual energy saving rate of the by-pass surface cooler is 3.56%,and the annual energy saving rate of the by-pass filter is 24.29%.The research results can provide a direction for the energy saving design of outdoor air units and a new idea for the design of outdoor air systems.
