Performance of two kinds of energy storage methods used in the household refrigeration is investigated and analyzed. A Mixture of De-ionized water with Natural graphite (3 wt%) and Paraffin (OM–46) were considered for phase change material (PCM) in the evaporator side and the condenser side respectively. After thorough investigation through experimental verification it is inferred that this set up has significantly enhanced the condenser heat transfer and the overall performance of the refrigerator. The variation in the compressor exit temperature exhibits a considerable dip in the maximum temperature of the compressor. This helps to increase the life time of the compressor. The evaporator and condenser temperature were approximately the same when the PCM is used on evaporator side. Under test conditions, this design of refrigerator could save energy by 16–22 % with PCM on condenser and 7–13 % with PCM on evaporator.

对家用制冷中两种储能方法的性能进行了研究和分析。对于蒸发器侧和冷凝器侧的相变材料（PCM），分别考虑了去离子水与天然石墨（3 wt％）和石蜡（OM-46）的混合物。通过实验验证进行深入研究后，可以推断出这种设置显着增强了冷凝器的传热能力和冰箱的整体性能。压缩机出口温度的变化表现出压缩机最高温度的明显下降。这有助于延长压缩机的使用寿命。当在蒸发器侧使用PCM时，蒸发器和冷凝器的温度大致相同。在测试条件下
