目前,在热水采暖系统的散热器计算方法和图表方面已有些资料,但它们规定只用于一定种类的散热器,或一定的散热器与系统的联接方式等,因此应用范围受到限制。我们分析了散热器计算中的主要矛盾——传热系数K=AΔt~B中的实验系数A、B值。在对多种A值、B值进行计算、制表的基础上绘制成了“热水采暖系统散热器片数计算图”(见图1),因此,它的使用就具有了普遍性,并使计算工作效率大大提高。凡本图未表示出的散热器,只需在相应的座标图上加入该种散热器的实验系数A值、B值、散热器散热面积f值线段,仍可
At present, there are some data on the calculation methods and diagrams of radiators for hot water heating systems, but they are stipulated only for certain types of radiators, or certain types of radiators and systems, etc., so the scope of application is limited. We analyzed the main contradiction in the calculation of the heat sink—the experimental coefficients A and B in the heat transfer coefficient K=AΔt~B. Based on calculations and tabulations of various A and B values, it is plotted as a “heating system heating system radiator number calculation map” (see Fig. 1). Therefore, its use has universality. Make the calculation work efficiency greatly improved. For heat sinks that are not shown in this figure, only the experimental coefficients A, B, and heat sink area f of the heat sink can be added to the corresponding graphs.
