This paper presents the energy consumption analysis of the refrigerator and the effect of the condenser on it. According to the Bureau of Energy Efficiency (BEE), India, the energy efficiency of electric appliances is the key parameter for testing their performance before domestic use. For energy consumption analyses, the experimentation was conducted on the domestic refrigerator (165 L) top-mounted evaporator by retrofitting the refrigerator with an Elliptical Helical Coil Condenser (EHCC) and existing refrigerator with a Straight Tube Condenser (STC). Box-Behnken Design (BBD) is very significant in determining the significant factor and reducing the number of experiments. BBD has been performed to analyze the significance of factors ambient temperature, fresh food compartment temperature and the heat load in energy consumption, and the Coefficient of Performance (COP) of a refrigerator. The heat load and the ambient temperature are both very significant in determining the refrigerator's energy consumption. The most important thing is to increase the liquid content in the charge before it is supplied to the evaporator to extract more amount of heat to increase the cooling effect. The ANOVA (Analysis of Variance) results show that the ambient temperature and the heat load were more significant in increasing energy consumption and decreasing the COP and vice versa. The results of ANOVA and the experiment are very close; the R2 value 0.995 precisely matches the R2 adj. value 0.994. The statistical analysis using the Box-Behnken design produces a good fitting of the modeled and experimental data set. The present study aims to examine the effects of said factors and the condenser on the domestic refrigerator's energy consumption and COP. The study exhibits some enhancement in the COP to 2.59 contrary to 2.45 and energy consumption reduced to 1191 Wh from 1755 Wh during the trial of 24 h.

家用冰箱能耗实验与统计分析案例

本文介绍了冰箱的能耗分析以及冷凝器对其的影响。据印度能源效率局(BEE)称,电器的能效是在家用前测试其性能的关键参数。对于能源消耗分析,实验是在家用冰箱 (165 L) 顶部安装的蒸发器上进行的,通过使用椭圆螺旋盘管冷凝器 (EHCC) 改造冰箱和使用直管冷凝器 (STC) 的现有冰箱进行改造。Box-Behnken Design (BBD) 在确定显着因子和减少实验次数方面非常重要。BBD 分析了环境温度、保鲜室温度和热负荷对能耗的影响,和冰箱的性能系数 (COP)。热负荷和环境温度在决定冰箱的能耗方面都非常重要。最重要的是在供给蒸发器之前增加装料中的液体含量以提取更多热量以增加冷却效果。ANOVA(方差分析)结果表明,环境温度和热负荷在增加能耗和降低 COP 方面更为显着,反之亦然。ANOVA的结果和实验很接近;R 最重要的是在供给蒸发器之前增加装料中的液体含量以提取更多热量以增加冷却效果。ANOVA(方差分析)结果表明,环境温度和热负荷在增加能耗和降低 COP 方面更为显着,反之亦然。ANOVA的结果和实验很接近;R 最重要的是在供给蒸发器之前增加装料中的液体含量以提取更多热量以增加冷却效果。ANOVA(方差分析)结果表明,环境温度和热负荷在增加能耗和降低 COP 方面更为显着,反之亦然。ANOVA的结果和实验很接近;R2值 0.995 精确匹配 R 2 adj。值 0.994。使用 Box-Behnken 设计的统计分析产生了建模和实验数据集的良好拟合。本研究旨在检验上述因素和冷凝器对家用冰箱能耗和 COP 的影响。该研究表明,在 24 小时的试验期间,COP 比 2.45 有所提高至 2.59,并且能耗从 1755 Wh 降低到 1191 Wh。
