Experimental data of a PCM storage prototype

This data set contains experimental test results carried out in the laboratory of Graz University of Technology, Institute of Thermal Engineering from October 2020 until February 2021. The storage prototype (volume 1 m³) was filled with pure water for the first five experiments. After these experiments the storage was filled with macro-encapsulated phase change material (PCM) (945 modules, 32 % of the storage volume) with the PCM ATS15 from the manufacturer Rubitherm and water. Temperature sensors (Pt100) were mounted at the top and the bottom port of the storage to measure the temperature of the heat transfer fluid (HTF = water), and in close distance to the volume flow measurement device ProMag50 (Vdot_MID). Four temperature sensors were mounted in thermowells equally spaced over the height of the storage tank (T_HTF1 – T_HTF4) to measure the temperature of the water in the storage. The ambient air temperature (T_AMB) was measured at a height of 1.5 m next to the storage.本数据集涵盖2020年10月至2021年2月期间，在格拉茨工业大学（Graz University of Technology）热工程研究所实验室完成的全部实验测试结果。实验初期的五次测试中，该储热原型装置（容积1 m³）仅填充纯水。完成上述五次实验后，储热装置更换为宏封装相变材料（phase change material，PCM）与水的复合填充介质：该宏封装相变材料共计945个模块，占储热装置总容积的32%，所用相变材料为厂商Rubitherm生产的ATS15型号PCM。为测量传热流体（heat transfer fluid，HTF=水）的温度，Pt100型铂电阻温度传感器被安装在储热装置的上下端口，同时在紧邻体积流量测量设备ProMag50（Vdot_MID）的位置也布设了该类传感器。另有4个温度传感器安装于测温套管（thermowells）中，沿储水箱高度方向等距分布，分别标记为T_HTF1至T_HTF4，用于测量储箱内部的水温。环境空气温度（T_AMB）的测量点位设置在储热装置旁1.5米高度处。
