【英文篇名】 Employment of flow adjustment formulas in heat metering systems 【作者中文名】 李建兴; 涂光备; 王毅; 【作者英文名】 By Li Jianxing ★; Tu Guangbei and Wang YiTianjin University; China; 【作者单位】 天津大学; 【文献出处】 暖通空调, Hv 运行调节; 量调节公式; 【英文关键词】 heat metering; operational adjustment; flow adjustment formula; 【摘要】 讨论分析了当前采用的供热系统量调节公式在计量供热系统中的适用性 ,提出了修正公式。结合具体算例 ,比较了两公式对不同工况的计算所引起的回水温度、散热量的偏差 ,指出在计量供热系统中应使用修正后的量调节公式。 【英文摘要】 Discusses the applicability of the existing flow adjustment formula for heating systems. Offers a modified formula through an analysis of the computational temperature difference of radiator. Compares the deviations of the return water temperature and heat emission calculated by the two formulas in different example conditions, suggesting that the modified formula is preferable to be adopted in design of the heat metering systems.
