水平串联热水采暖系统在散热器面积或片数计算上,其基本公式和计算步骤与一般双管系统并没有什么两样。所不同的是,水平串联系统各组散热器内水的平均温度和传热系数沿着水的流动方向依次降低。这就使得该类系统散热器的计算工作量较之于双管系统大为增加。有些图表计算法是以减轻工作量、加快设计速度为目的而编制的。但是,这些图表的根据不够充分。因此,应该探讨一下较为切实可行的图表计算法。这种方法应有足够的依据,即应吸取国内有关的研究成果;图表应有较大的 The horizontal series hot water heating system does not differ from the general two-pipe system in the calculation of radiator area or number of sheets. The difference is that the average temperature and heat transfer coefficient of the water in the radiators of the horizontal series system are successively reduced along the flow direction of the water. This makes the calculation workload of such system radiators increase greatly compared with double-pipe systems. Some chart calculations are prepared for the purpose of reducing the workload and speeding up the design. However, the basis of these charts is not sufficient. Therefore, we should explore more practical chart calculations. This method should be based on sufficient evidence that relevant domestic research results should be drawn; the chart should have larger
