供暖室内温度控制技术综述

Summary of Heating Indoor Temperature Control Technologies

分析供暖室内温控技术现状,对供暖室内温控装置、控制算法进行综述。与国外相比,我国供热系统缺乏热计量装置的使用及室内温度调控方法,用户很难实现用热量实时调节。用户对热量的概念不清楚,按面积收费的计费机制也导致部分用户节能的积极性不高。国外的室内温控设备已经相当成熟,我国在室温控制方面的自动化程度不高。将相变蓄热技术与室内温度控制相结合,不仅可以提高室内热舒适性,而且对降低供暖能耗有重大意义。在供暖室内温度的控制算法中,除传统PID控制外,模型预测控制(MPC,基于模型的闭环优化控制策略)以及与其关系密切的能耗模拟与控制算法将成为发展方向。

The present situation of the heating indoor temperature control technologies is analyzed,and the heating indoor temperature control devices and control algorithms are summarized.Compared with foreign countries,China's heating system lacks the use of heat metering devices and indoor temperature regulation methods,and it is difficult for users to achieve real-time heat regulation.The user's concept of heat is not clear,and the charging mechanism of charge by area also leads to the low enthusiasm of some users to save energy.Foreign indoor temperature control equipment has been quite mature,and China's degree of automation in room temperature control is not high.The combination of phase change heat storage technology and indoor temperature control not only can improve indoor thermal comfort,but also has a significant meaning in reducing heating energy consumption.In heating indoor temperature control algorithm,in addition to the traditional PID control,the model predictive control(MPC,model-based closed-loop optimization control strategy)and energy consumption simulation and control algorithm closely related to it will become the development direction.
