热水供应系统中D—L比温降计算法

Calculative method of D-L specific temperature drop in hot water system

分析了目前热水供应系统中各种比温降法计算管段节点水温的方法 ,指出了存在的问题 ,提出了采用管径—长度比温降法 (下称D—L比温降法 )计算各管段的节点水温。

Some problems in calculating the water temperature at pipe joint of hot water system with various calculative methods of specific temperature drop are described. The calculative method of pipe diameter to length ratio temperature drop (called calculative method of D-L specific temperature drop) has been developed in this paper.
