Estimation of preheating time for building intermittent heating subject to changes in outdoor temperature and solar radiation

The procedure MainProcedure_Step2.m can be executed to obtain D preheating times that correspond to D-group model parameters. The 100 models are generated based on the given 100-group model parameters. For each model, the predicted indoor temperature corresponding to the model is obtained by bringing in the heating start time and future weather data. The optimal preheating time is obtained when the indoor temperature is the same as the setpoint at the set time. The procedure MainData_example.m can be executed to obtain 20 sets of data in similar external environments, as well as the results of model validation and preheating times validation.

运行MainProcedure_Step2.m，可获取与D组模型参数一一对应的D个预热时长。本数据集基于给定的100组模型参数生成了100个模型。针对每个模型，将供暖启动时刻与未来气象数据代入后，即可得到该模型对应的室内温度预测结果。当预设时刻的室内温度与设定目标温度一致时，此时对应的预热时长即为最优预热时长。运行MainData_example.m，可获取20组外部环境相似的数据集，同时包含模型验证与预热时长验证的相关结果。
