摘要
针对目前普遍出现的居住建筑低温热水地面辐射供暖系统供回水温度确定不合理的现象,分析其弊端,给出低温热水地面辐射供暖系统供回水温度的计算方法,并通过实例计算,得出"寒冷B区的节能型居住建筑,低温热水地面辐射供暖系统的供水温度取值38～39℃,回水温度取值31～32℃即可满足使用要求"的结论,并简单阐述合理确定低温热水地面辐射供暖系统供回水温度带来的优势。
In view of the general irrational determination of the supply and return water temperatures for the residential buildings with the low temperature hot water floor radiant heating system,it analyzed the disadvantages and proposed a calculation method for the supply and return water temperatures in the system.Meanwhile,through example calculation,it concludes that the requirement will be met for the energy-saving residential buildings in cold（B） zones,when the supply water temperature is between 38℃ to 39℃ and the return water temperature is between 31℃ to 32℃.And the advantages of rational determination of the supply and return water temperatures in the low temperature hot water floor radiant heating system are also briefly illustrated.
