散热器和低温水辐射采暖系统不同连接方式及控制策略动态仿真

散热器和低温水辐射采暖系统最佳连接方式一直是业界探讨的重要课题之一。本文以动态模型为手段，模拟和分析直接、混水泵及间接连接方式系统动态响应和能耗。仿真结果表明，地板热情性的提高延长了室内温度达到稳态时间；地暖系统直接连接方式是不适宜的；混水泵和间接连接系统可节省燃料消耗约17％。从控制角度看，间接连接系统具有更好的稳定性和控制精度。

Dynamic simulations based on different connection approaches and control strategies between radiant floor and radiator heating systems

One of the important topics in heating field is what the best way of connection is between radiant floor heating and radiator heating systems. In this paper,based on developed dynamic system models,the dynamic responses and energy consumption in the systems by using direct,mixing water pump and indirect connection methods were simulated and analyzed. The results showed that larger thermal capacity of the floor construction resulted in more time to reach steady state value of indoor air temperature;the direc...
