Abstract

There is a non-negligible variation in climatic conditions in different geographical locations of Sri Lanka. Testing the performance under single climatic condition will not reflect the actual performance of a refrigerator at its intended deployment. This research is aimed at studying the performance of a domestic refrigerator unit under simulated climatic conditions representing different climate zones in Sri Lanka with respect to its dry bulb temperature. Experiments were conducted under controlled environmental conditions to emulate the climatic conditions of different climatic zones in Sri Lanka. Average hourly power consumption under each climatic condition was calculated from the results. Projected annual energy consumption and performance of the overall refrigeration cycle were also estimated. Results indicated a 5.6 % increase of energy consumption per 1 □C increase of ambient temperature. Annual power consumption shows 54.2% variation within the evaluated locations. A simulation model was developed to perform the evaluation. Existing mathematical model was adopted to calculate the performance of the refrigeration cycle.

斯里兰卡不同环境条件下家用冰箱稳态性能变化

斯里兰卡不同地理位置的气候条件有不可忽视的差异。测试在单一气候条件下的性能不能反映制冷机在其预期部署时的实际性能。本研究的目的是研究一个家用冰箱机组的性能在模拟气候条件下代表不同的气候区在斯里兰卡相对于其干球温度。实验在受控环境条件下进行，模拟斯里兰卡不同气候带的气候条件。根据结果计算了各气候条件下的平均小时用电量。预计的年度能源消耗和整个制冷循环的性能也进行了估计。结果表明，环境温度每升高1℃，能耗增加5.6%。年用电量在被评估地区之间的差异为54.2%。开发了仿真模型来进行评估。采用已有的数学模型计算制冷循环的性能。
