Summary:This paper, the large-scale heat network is now commonly used outdoor mechanical circulating hot water heating-supply tube net. Hydraulic regime was analyzed in district heating system at first, and then established hydraulic calculation model basing on the fact of operation. At the same time thermal condition was also brought and thermal calculation model was established from the node thermal balance standpoint. Combined the hydraulic calculation module with the thermal calculation module and other optimization or search modules, a general calculation model is designed for both radiate network and loop-network, which not only simulates the practical condition, but also offers the data of ideal condition. This model is proved to be correct, helpful, energy saving and economical in adjustment of district heating system.
