摘　　要：提出了基于传感器和空气处理机组的一个控制住宅通风系统策略。该策略是基于传感室外空气和排风中的二氧化碳浓度和含湿量。通风换气率可切换为两个状态:高换气率和低换气率。对现有安装机械通风系统控件的住宅进行了测量。结果表明,通风时间可以最少减少房间里CO2浓度和湿度水平没有显著变化时间的37%,相应的风扇节能可以达到35%。This paper presents a strategy for a simple demand controlled ventilation system for single family houses where all sen- sors and controls are located in the air handling unit. The ventilation rate can be switched between two flow rates： a high rate and a low rate. Measurements were performed on an existing single family house where the controls were installed on the existing mechan-ical ventilation system. The results showed that the ventilation can be reduced to the low rate 37% of the time without signi？cant changes in the CO2-eoncentration and moisture level in the house. In theory this gives a 35% saving on electric energy for fans.
