供热通风与空气调节（Heating,Ventilation and Air Conditioning,HVAC）系统是大型建筑的重要组成部分之一,在商业超市、高层写字楼、室内体育场馆等建筑中广泛使用。HVAC系统的能耗优化控制是建筑设计中的重要问题,也是使用HVAC系统的业主特别关心的问题。实现对HVAC系统能耗的预测是对其进行优化控制的前提,本论文基于受限玻尔兹曼机（Restricted Boltzmann Machine,RBM）和人工神经网络（Artificial Neural Network,ANN）提出了一种预测HVAC系统能耗的新模型。新模型利用了RBM强大的特征提取能力和无监督学习能力,同时利用了ANN的非线性拟合能力。首先,输入训练数据对RBM进行预训练,使得RBM能够自主提取数据的隐含特征信息以供ANN进行学习;然后,将学到的隐含特征信息与原始输入进行有机组合,形成一个协调一致的集合;最后,将整个集合作为输入数据对ANN进行训练,得到预测模型。为了测试新预测模型的准确性,本文利用重庆市某大型商业超市的真实HVAC能耗数据进行数值实验。实验结果表明,新模型的特征提取能力和预测能力都明显高于单独使用RBM或ANN时的结果,与其它HVAC系统能耗预测模型的对比试验结果也表明该预测模型具有较高的准确性。具体指标表现为该模型的平均绝对误差（Mean Absolute Error,MAE）为0.1541%,均方误差（Mean Square Error,MSE）为0.3405%,均方根误差（Root Mean Square Error,RMSE）为0.5835%,均处在一个极低的水平,拟合度值（R）为1,也处于一个较好的水平。数值实验的结果表明本文提出的新模型是准确可靠的,能够用于HVAC系统能耗预测。本文提出的HVAC系统能耗预测模型有望应用于实际的HVAC能耗预测中,为HVAC系统能耗优化控制提供准确的预测保障,同时为HVAC系统能耗预测问题的研究提供新的视角。
