摘要
通过对10—12月严寒地区45个居住建筑室内空气PM_(2.5)、甲醛、二氧化碳浓度进行测试研究,结果表明室内污染物浓度超标,而新风系统运行必然会增加室内热(冷)负荷。为降低新风系统能耗,进行基于室内污染物浓度控制热回收型新风系统研究,经计算该装置及控制方法对有效降低新风系统能耗及改善室内环境具有重要意义。
The indoor pollutants concentrations of PM 2.5,formaldehyde and carbon dioxide in 45 residential buildings in severe cold area in three months(October,November or December)were tested.The results indicated that indoor pollutants exceeded the standards and the operation of the fresh air system would inevitably increase the indoor load.A heat recovery fresh air system device and the control mechanism based on indoor pollutant concentration were researched in order to reduce the energy consumption of the fresh air system.It is important to reduce the energy consumption of fresh air system and improve the indoor air quality.
