A simple and fast methodology for the design of platebased LHTES systems.

One of the factors that limit the commercial deployment of LHTES systems is their complex design procedure; accordingly, there is a need of tools that allow their fast and accurate simulation. In the present work, a correlation that allows the determination of the discharging time of plate-based LHTES systems is first presented. Based on that correlation and other parameters constrained by the application, a simplified methodology for the design of plate-based LHTES systems is presented. It consists of 3 simple steps and allows a complete sizing of the system without the need of simulations. This reduces the design procedure time from days/hours to minutes.

限制潜热型热能存储（Latent Heat Thermal Energy Storage, LHTES）系统商业化部署的瓶颈之一，是其复杂的设计流程；因此亟需能够实现该类系统快速且精准仿真的工具。本研究首先提出了一种可用于计算板式潜热型热能存储系统放热时长的关联式。基于该关联式以及应用场景约束的其他参数，本研究进一步提出了一套板式潜热型热能存储系统的简化设计方法。该方法仅包含三个简易步骤，即可在无需开展仿真的前提下完成系统的完整参数选型，可将原设计流程的耗时从数天/数小时压缩至数分钟。
