不同外墙结构建筑物供暖系统的控制策略仿真

Simulations of control strategies for heating system of buildings with different types of outer-wall

创建了不同外墙结构建筑物供暖系统的动态模型。通过模型开环实验得出了系统特性及各参数之间的关系,并模拟了不同控制策略时供暖系统的动态响应。结果表明:缺乏对室外温度和热用户额外得热量有效补偿会导致室内温度较大波动及燃料浪费;采用燃料和室内温度控制器共同作用的控制策略既能提高用户热舒适性,又可降低燃料消耗近16%。

Develops a dynamic model of heating system of buildings with different types of outer-wall. Obtains the system characteristics and relationships among the parameters based on open loop tests of the model. Simulates the dynamic responses of the heating system by applying different control strategies. The results show that lack of proper compensation for outdoor air temperature fluctuation and additional heat gains results in great fluctuation of indoor air temperature and fuel waste; the control strategy by using fuel and indoor air temperature controllers could both improve thermal comfort of end-users and decrease fuel consumption by nearly 16%.
