住宅新风系统的控制仿真

Control Simulation of Residence Fresh Air System

住宅新风系统为人们创造了健康的室内环境,但新风量不能同时兼顾能耗和室内空气品质对它提出的要求,因此,提出了基于室内空气品质的需求控制通风策略。以该策略设计的控制系统,控制对象为新风量,控制指标为综合污染物浓度,控制方法为模糊PID,最后,用MATLAB软件仿真模拟,根据仿真曲线分析控制系统的效果。结果表明,通过控制可以有效地将室内存在的污染物浓度降低到允许范围内,并可满足人体对室内空气品质的要求。

A healthy environment can be provided for people by the fresh air system,but the energy consumption and indoor air quality can not be both taken into account.So a demand control ventilation strategy was proposed out,that based on indoor air quality.In the design of control system,the fresh air volume is used as control object,the comprehensive pollutant concentration is used as control index,the fuzzy PID is adopted as control method.Finally,MALTAB simulation was applied to the simulation,and the simulation curve were used to analyze the effect of the control system.The results that the concentration of the indoor pollutants can be effectively reduced,and it can meet the requirement of the indoor air quality.
