面向能源规划的围护结构负荷简化预测模型

提出了一种单体建筑围护结构动态空调负荷预测的简化模型,在保证满足区域预测结果精度的同时,将模型输入参数简化至6个;同时采用劳伦斯伯克利国家实验室开发的Buildings Modelica Library开源模型库来建立模型,并验证了该模型的精度;在此基础上运用线性集合法对简化模型进行降阶处理,有效提高了负荷预测的计算速度.该模型的提出,使得区域每栋建筑简化快速模拟均成为可能,为进一步推广到区域空调负荷预测提供了方法基础.

Energy Planning oriented Simplified Models of Envelope Dynamic Load Prediction for Individual Buildings

A simplified model of envelope HAVC load prediction for individual building was proposed, in which the number of input parameters was reduced to six, and prediction accuracy guaranteed. This building thermal dynamic model was established with the open source library of Buildings Modelica Library developed by Lawrence Berkeley National Laboratory. The linear aggregation method was used to reduce the order of simplified model, in order to accelerate calculation. This simplified model makes possible the fast calculation of HVAC load for each individual building, and hence provides the method basis to expand to the regional scale simulation. Finally, discussion was conducted to expand the method in regional dynamic load prediction in the future.
