摘要
提出了一种改进的基于CO2检测的新风量控制方法.该方法通过检测新风、回风CO2浓度值及当前新风量,实时确定室内人数,再根据ASHRAE62-2001Standard实时确定系统新风量.仿真结果表明,对于所选办公建筑,应用该方法后室内全天CO2浓度在1000(10-6)以下,TVOC浓度在300μg/m3以下,与传统CO2浓度监测法相比,该方法保证了全天均有良好的室内空气品质.
This paper puts forward a fresh air quantity control method based on CO2-detected.the control scheme is proposed by vent area and detecting the current fresh air quantity,CO2 consistence of fresh air and return air to monitor the people indoor.The determine the fresh air quantity based on ASHRAE62-2001Standard.Simulation results show that,compared to the traditional CO2-DCV scheme,the improved scheme guarantees the CO2 consistence below 1000（10-6）,TVOC consistence below 300 g/m3 in selected office,and obtains a good indoor air quality all day.
