供热系统节能运行调节分析

Analysis of Energy-Saving and Adjustment of Heating System

根据兰州市的气候特征,以某高校供热系统为例,对质调节与分阶段改变流量的质调节进行计算分析,得出配有变频调速水泵的分阶段改变流量的质调节,即“小流量,大温差”的运行方式,具有节能性显著、水力稳定性好、经济性突出的优点,是校园集中供热的首选调节方式。

According to the climate characteristics of Lanzhou,taking the heating system of a university as an example,the quality regulation and the quality regulation of changing flow in stages are calculated and analyzed,and the quality regulation of changing flow by stages with variable frequency variable speed pump is obtained,that is,the operation mode of“small flow,large temperature difference”,has the advantages of energy saving,good hydraulic stability and outstanding economy.It is the preferred adjustment mode of campus central heating.
