某高校建筑集中供热节能控制系统设计与实现
Design and implementation of energy saving control system for building centralized heating in a university
摘要：
针对夏热冬冷地区某高校集中供热系统运行管理模式粗放、换热站热力不均衡、大流量小温差等问题，提出了一种三级逆向调节改造方法，即分别对建筑末端空调机组、二级换热站、一级换热站进行逐级精细化调节,并结合互联网技术实现系统的远程监控。运行结果表明，在满足供热需求和室外负荷条件基本一致的前提下，与节能改造前2015—2016年供热季相比，2016—2017年供热季节省蒸汽量19.56%、节省电量27.10%、减少二氧化碳排放553.94 t，投资回收期约3 a，经济环保效益良好。
Abstract：
In view of the poor operation and management mode, thermal imbalance of heat exchange station, large flow and small temperature difference and other problems of centralized heating system in a university in hot summer and cold winter zone, proposes a three-level reverse regulation transformation method to adjust the terminal air conditioning unit, secondary heat exchange station and primary heat exchange station step by step, and realizes the remote monitoring of the system by the internet technology. The operation results show that, on the premise of meeting the heating demand and outdoor load conditions, compared with the heating season in 2015-2016 before the energy saving transformation, in the heating season in 2016-2017 steam capacity and electricity are saved by 19.56%, 27.10%, respectively, carbon dioxide emission is reduced by 553.94 t, and the payback period is about 3 years, with good economic and environmental benefits.
