具有相变材料（PCM）板和气隙的热交换器是建筑通风系统中储存能量的解决方案。这种蓄冷装置既可用于冬季制冷，也可用于夏季调峰。然而，为了评估和优化这个系统，数值模拟是强制性的。为此，开发了一个数值模型，同时考虑到在PCM板和板与气流之间的热传递的传导。本文提出了该模型，并使用我们的实验数据进行了验证。
Heat exchangers with phase change material (PCM) slabs and air gaps are a solution to store energy in building ventilation systems. Such storage unit can be used both for free cooling and peak load shaving in winter and in summer. However, in order to assess and optimize this system, numerical simulation is mandatory. For that purpose, a numerical model is developed taking into account both conduction in the PCM slab and heat transfer between the slab and the airflow. This model is presented in this paper and validated using our experimental data.
