本研究的目的是建立蓄热相变材料（PCM）的设计标准，蓄热模块位于传热流体流经的储罐内。满足该目标所需的范围包括（1）审查潜热储能方面的现有研究，（2）开发包含PCM储能系统的数学模型，（3）模型验证，（4）使用模型进行参数研究，以确定此类系统设计中的关键参数，以及（5）评估。以及各种系统设计的比较。在本报告中，重点将放在具有矩形几何形状的相变容器上。数学公式和数值结果基于笛卡尔坐标系下的一维导热。Timmer[1]在论文中给出了填充床中球形容器的配方和结果。 虽然矩形和球形几何体的公式之间确实存在显著差异，但从概念上讲，这两种几何体是相同的。因此，为了提高清晰度，每种表述及其结果将在单独的报告中呈现。

The objective of this study is to establish design criteria for contained phase-change material (PCM), thermal-energy storage modules located within a tank through which a heat transfer fluid flows. The scope required to meet the objective includes (1) review of the existing research in latent heat thermal energy storage, (2) development of mathematical models for contained PCM thermal energy storage systems, (3) model validation, (4) parametric studies using the models to establish key parameters in the design of such systems, and (5) evaluation.and comparison of various system designs. In this report the emphasis will be on phase change containers which have a rectangular geometry. The mathematical formulation and numerical results are based on one-dimensional conduction heat transfer for a cartesian coordinate system. The formulation and results for spherically shaped containers arranged in a packed bed can be found in the thesis by Timmer [1]. Although significant differences do exist between the formulations for the rectangular and spherical geometries, conceptually the two are identical. Thus, each formulation and the results following from that formulation are presented in separate reports in an effort to enhance clarity.
