本文研究了在冰箱蒸发器的外表面上添加相变材料 (PCM) 板的效果。提出了蒸汽压缩循环的动态模型，包括相变材料的存在及其实验验证。 PCM系统的仿真结果表明，热惯性的增加全局增强了蒸发器的传热，并允许更高的蒸发温度，从而提高了系统的能源效率。 PCM 中存储的能量在关闭周期期间向制冷机电池产生，并允许在没有电源的情况下连续运行几个小时。
This paper studies the effect of adding a phase change material (PCM) slab on the outside face of a refrigerator evaporator. A dynamic model of the vapour compression cycle including the presence of the phase change material and its experimental validation is presented. The simulation results of the system with PCM show that the addition of thermal inertia globally enhances heat transfer from the evaporator and allows a higher evaporating temperature, which increases the energy efficiency of the system. The energy stored in the PCM is yielded to the refrigerator cell during the off cycle and allows for several hours of continuous operation without power supply.
