为了解使用相变材料（PCM）的家用冰箱性能的提升情况，进行了一项实验研究。相变材料被用作潜热蓄热系统以增强蒸发器的热传递。相变材料位于蒸发器箱体的五个面之后，蒸发器盘管浸于其中。在不同热负荷下，本实验使用水（熔点0°C）和共晶溶液（熔点 -5°C）作为相变材料。根据相变材料的类型和热负荷，观察到使用相变材料时，制冷循环的性能系数（COP）相对于不使用相变材料提高了约20 - 27%。随着相变材料数量的增加（从0.003立方米增加到0.00425立方米），性能系数提高了约6%。在两种不同的相变材料之间，共晶溶液的性能系数提升高于水。使用相变材料的实验结果证实，根据热负荷和相变材料的类型，每个循环的平均压缩机运行时间显著减少，与不使用相变材料相比，减少了约2 - 36%。
An experimental investigation has been carried out to know about the performance improvement of a household refrigerator using phase change material (PCM). PCMs are used as latent heat thermal storage system to enhance the heat transfer of the evaporator. PCM is located behind the five sides of the evaporator cabinet in which the evaporator coil is immersed. Water (melting point 0°C) and Eutectic solutions (melting point −5°C) are used as PCMs for this experiment at different thermal loads. Depending on the types of PCM and thermal load, around 20–27% COP improvement of the refrigeration cycle has been observed with PCM with respect to without PCM. With the increase of the quantity of PCM (0.003 to 0.00425 m3) COP increases about 6%. Between two different PCMs the COP improvement for Eutectic solution is higher than Water. The experimental results with PCM confirm that, depending on the thermal load and the types of PCM average compressor running time per cycle is reduced significantly and it is found about 2–36% as compared to without PCM.
