优化策略有效降低PM2.5浓度，并节省能源和成本

Ci,in represents the concentration of pollutant i, and the corresponding Ci,st represents the threshold value for pollutant i. The previous section provides specific data for a bedroom in Beijing [3], which demonstrates that the optimization strategy can effectively reduce PM2.5 levels below the threshold, a result that traditional approaches fail to achieve. Additionally, the optimization strategy reduces energy consumption by 8.7% annually compared to traditional strategies. Furthermore, the operating costs of this optimal strategy have decreased by 15%, as shown in Figure 1.
