Determination of Distribution Coefficient of Radiator in Vertical Single-pipe Heating System

在散热器热特性分析的基础上 ,推导出散热器进流系数的确定原则 ,指出应根据散热器的可调节性确定合适的进出口温差 ,进而确定合理的进流系数大小。并结合实例 ,给出实际进流系数的确定方法和步骤。

Based on the analysis of the radiator's thermal ch aracteristics, this paper derives the expression of radiator's theoretical distribution coefficient and points out that the size of the by-pass pipe should be determined according to t he water flow distribution in the branch of the radiator and the by-pass pipe. T he author also presents the methods and steps of determining the actual distribu tion coefficient in the light of the matter of retrofit heating system.
