Design and implementation of energy saving control system for building centralized heating in a university

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.
