摘要
管段流量与终点水温的关系,是热水供应系统中循环泵选择计算研究的一个重要理论依据。热水供应系统中,当管道起点水温确定时,终点水温随着管道流量的增加而升高。循环泵流量的计算是否加入附加循环流量,应考虑管网中各管段流量分配的实际情况。
By theoretical and experimental study,it can be concluded that the temperature of water at the end-point of a pipe will increase with the increase of the flow rate in the pipe if the temperature at the entrance of the same pipe keeps constant.Therefore,this conclusion should be taken into account when we study how to select one circulation pump with reason in a hot-water supply system.
