采用分阶段变流量质调节方式的供暖期细分

Subdivision of Heating Period Using Centralized Control with Flow Varied by Steps

针对目前供热系统采用分阶段变流量质调节时,简单地将供暖期划分为初寒期、严寒期、末寒期3个阶段的现状,提出在详细分析气象资料的基础上,对供暖期进行细分。以天津地区作为研究对象,将供暖期细分为10个阶段,循环泵能耗比细分前下降13%。

In view of the status that the heating period is usually divided into three stages including ini- tial cold period, severe cold period and final cold peri- od for the current heating system using centralized con- trol with flow varied by steps, it is put forward that the heating period should be subdivided based on analysis of meteorological data. Taking Tianjin area as research object, the heating period is subdivided into ten sta- ges, and the energy consumption rate of circulating pump is 13 % lower than that before the subdivision.
