根据我国多年的实践和分析比较,一般认为,多层民用建筑的热水采暖系统,以顺流式垂直单管为最经济合理。但是,由于这种系统中每个散热器的进回水温度不同,从而平均温度都不一样,因此给散热器片数的计算带来了不少麻烦。特别当采用流量分配法(或不等温降法)来计算管路时,则更是如此。因此必须简化散热器的计算,减轻这一计算工作量。一、采用等温降法计算管路时,散热器散热量及片数的简化计算试考察一个五层楼的立管。设各层楼的
According to our country’s many years of practice and analysis, it is generally believed that the hot water heating system for multi-storey civil buildings is the most economical and reasonable. However, since the temperature of the inlet and outlet water of each radiator in such a system is different, and the average temperature is not the same, the calculation of the number of radiators brings a lot of trouble. This is especially true when the flow distribution method (or non-isothermal drop method) is used to calculate the piping. Therefore, it is necessary to simplify the calculation of the radiator and reduce this calculation workload. First, when using isothermal drop method to calculate the pipeline, a simplified calculation of heat dissipation and number of radiators will be examined in a five-story riser. All floors
