目前,我国供热系统普遍存在系统冷热不均的水平失调现象,即近热源用户差压大,远端用户差压小。它是造成供热系统大流量、小温差运行方式和形成供热量过大、电耗大、运行费高等系统不能经济运行的主要原因。热力公司的统计资料表明:热网实际循环水量是设 At present, China’s heating system generally has the phenomenon of unbalanced levels of hot and cold levels of the system, that is, users of near-heat sources have large differential pressure and remote users have low differential pressure. It is the main reason for the system’s inability to operate economically due to the large flow rate of the heating system, the small temperature difference operation mode, and the formation of excessive heat, high power consumption, and high operating costs. Thermal company statistics show that the actual circulating water volume of the heating network is
