摘要
本文利用多种建筑BIM分析软件,建立了某医院大楼的全年逐时的建筑能耗模型,分析了机房系统各项能耗的特性。本文还利用建筑能耗模型就建筑冷热负荷的预测算法展开了研究,利用全年模拟数据展开了两种预测算法的准确性。最后,本文结合了PLC研究了负荷预测控制与模糊PID结合的冷冻水变流量自动控制系统,并就控制效果及节能效果展开了讨论。
This paper uses BIM analysis tool to establish a year-round building energy consumption model of a hospital building and analyzes the characteristics of the energy consumption in the air-conditioned room in several parts.This paper also studies the prediction algorithm of building cooling and heating load,and uses the annual simulation data to develop the accuracy of the two prediction algorithms.Finally,this paper uses PLC to study the automatic control system of chilled water variable flow combined with load prediction control and fuzzy PID,and discusses the control effect and energy saving effect.
