Effective estimation of the state-of-charge of latent heat thermal energy storage for heating and cooling systems using non-linear state observers - data

The data describe the simulation of mathematical models of thermal energy storage units and their state-of-charge observers.The data is provided by txt files. The simulation results include the time column for each file. Two different thermal energy storage are analyzed. For cooling applications, an ice tank is modeled and for heating applications, a shell-and-tube configuration unit is employed. The charging and discharging processes are simulated. The quantification of the sensible and latent heat stored by the tanks is carried out. Simulations of non-linear observers' performance were done for charging-discharging cycles. The errors of the non-linear observers included the estimation of the internal temperatures of the phase change material and the heat transfer fluid. They are split into two txt files for each simulation due to 40 variables being simulated.The header of each column is the name of the variable used in the legend of the plots. The txt files are named according to the number of the plots.Reserch results based upon these data are published at https://doi.org/10.1016/j.apenergy.2022.120448本数据集围绕热能存储单元（thermal energy storage unit）及其荷电状态观测器（state-of-charge observer）的数学模型仿真展开描述，数据以纯文本（txt）文件格式提供。每个数据文件均包含时间列。本次研究共分析了两类不同的热能存储单元：针对制冷应用场景，构建了冰蓄冷罐的仿真模型；针对制热应用场景，则采用了管壳式结构的储能单元。仿真覆盖了充热与放热过程，并对两类蓄热罐所储存的显热与潜热进行了量化分析。此外，针对充放热循环开展了非线性观测器的性能仿真，评估其对相变材料（phase change material）内部温度及传热流体（heat transfer fluid）温度的估算误差。由于单次仿真共涉及40个变量，每个仿真的结果被拆分为两个txt文件。每一列的列标题即为绘图图例中所使用的变量名称。txt文件以对应绘图的编号命名。基于本数据集的研究成果已发表于https://doi.org/10.1016/j.apenergy.2022.120448。
