室外温度对地板辐射供暖供水温度影响分析

Analysis on the Influence of Outdoor Temperature on Radiant Floor Heating Supply Water Temperature

为了优化集中供暖调节方法,进一步降低机组冬季运行能耗,本文研究了室外温度与低温地板辐射供暖供水温度的关系。首先利用DeST模拟了建筑的热负荷需求,并结合地板辐射供暖传热模型,在供需匹配的情况下,建立了最不利室外温度与低温地板辐射供暖供水温度之间的定量关系。研究了在不同供回水温差下,室外温度与供水温度关系,为冬季低温地板辐射供暖系统日间的运行提供了技术参考。

To optimize the centralized heating regulation method, the unit's winter operation energy consumption is further reduced, This paper studies the relationship between outdoor temperature and low temperature radiant floor heating supply water temperature. Firstly, using DeST to simulate heating load demand of the building, combining with the radiant floor heat transfer model, when the supply and demand match, the quantitative relationship between the most unfavorable outdoor temperature and the low-temperature radiant floor heating supply water temperature was established. The relationship between the outdoor temperature and the supply water temperature under different supply and return water temperature difference was studied, which provided a technical reference for the operation of the low temperature floor radiant heating system during the day in winter.
