摘　　要：为了研究恒温阀作用于低温地板辐射供暖系统时室内温度的动态响应,从恒温阀的室温控制原理出发,对房间、辐射地板、外围护结构的动态传热过程进行了分析,建立了动态传热的数学模型。依据数学模型搭建了低温地板辐射供暖系统室温动态控制的Simulink仿真模型,并对不同工况和不同室温设定模式下的室内温度和流量变化规律进行动态仿真,得到了不同模式下室内温度的变化曲线。In order to study the room temperature dynamic response of low temperature radiant floor heating system under the action of thermostat valve.This paper from room temperature thermostat valve control principle,the room,radiant floor,heat transfer process dynamic external structure is analyzed,the mathematical model of dynamic heat transfer.Build a mathematical model based on Simulink models of low-temperature radiant floor heating system dynamic temperature control.And different conditions and indoor temperature and flow rate variation of different temperature setting mode for dynamic simulation,got the curves of different modes of the indoor temperature.
