Abstract

The usage of Chlorofluorocarbons (CFCs) and Hydrochlorofluorocarbons (HCFCs) is currently being phased out since both substances cause ozone depletion and global warming potential. Many investigations have been conducted in recent years to develop environmentally acceptable alternative refrigerants. Dimethyl ether (DME) is a good contender among the various alternative refrigerants because it has minimal ozone depletion potential (ODP) and global warming potential (GWP). The performance of dimethyl ether as an alternative refrigerant to R134a was evaluated in this study. This study compared the performance of a freezer while using R134a and when using dimethyl ether. The use of dimethyl ether was varied based on mass, namely 60 grams, 70 grams, and 80 grams, or in percentages as much as 40%, 46.7%, and 53.3% of the total mass if R134a. The results showed that using dimethyl ether instead of R134a improved freezer performance. Based on the mass variation, it was found that the chilling time using 80 grams of DME is almost the same as R134a. Even, the Energy Efficiency Ratio (EER) is higher than R134a. Therefore, R134a can be substituted by 53.3% mass of DME in a freezer.

使用二甲醚（DME）替代 R134a

由于氯氟化碳（CFCs）和氯氟烃（HCFCs）会导致臭氧层破坏和全球变暖，因此目前正在逐步淘汰这两种物质。近年来，为开发环境可接受的替代制冷剂进行了许多调查。二甲醚（DME）是各种替代制冷剂中的佼佼者，因为它的臭氧消耗潜能值（ODP）和全球变暖潜能值（GWP）都很低。本研究对二甲醚作为 R134a 替代制冷剂的性能进行了评估。这项研究比较了使用 R134a 和使用二甲醚时冰柜的性能。二甲醚的使用量按质量计算，分别为 60 克、70 克和 80 克，占 R134a 总质量的比例分别为 40%、46.7% 和 53.3%。结果表明，使用二甲醚代替 R134a 提高了冷冻室的性能。根据质量变化，发现使用 80 克二甲醚的冷冻时间与 R134a 几乎相同。甚至，能效比（EER）也高于 R134a。因此，在冷冻机中可以用 53.3% 的二甲醚替代 R134a。
