Abstract

Isobutane (R600a) is the most used refrigerant for low-capacity refrigeration systems, as it combines excellent environmental properties and offers good energy performance. A real possibility to increase the efficiency of these systems is using new refrigerant mixtures offering energy improvements (being compatible with existing systems). This work, from an experimental perspective, proposes mixtures of dimethyl ether and butane (RE170/R600) as potential drop-in refrigerants of R600a systems. For a given operating condition, the energy performance of RE170/R600 mixtures with maximum proportion of 27.5 % of RE170 has been tested using a water-to-water single-stage compression cycle, measuring COP increments from 10.1 to 17.6 % in relation to R600a. Then, the blend RE170/R600 (15/85 %), considered as the potential drop-in fluid of R600a, has been tested in a wide range of operating conditions, concluding that it offers the same cooling capacity than R600a but with COP increments from 12.6 % to 17.6 %.
实验验证 RE170/R600(二甲醚/丁烷)混合物是一种优于 R600a(异丁烷)的制冷剂
异丁烷(R600a)是低容量制冷系统中使用最多的制冷剂,因为它兼具出色的环保特性和良好的节能性能。要提高这些系统的效率,一个真正的可能性是使用新的制冷剂混合物来提高能效(与现有系统兼容)。本研究从实验角度出发,提出了二甲醚和丁烷的混合物(RE170/R600)作为 R600a 系统的潜在替代制冷剂。在给定的运行条件下,使用水-水单级压缩循环测试了 RE170 最大比例为 27.5 % 的 RE170/R600 混合物的能量性能,测量了相对于 R600a 的 COP 增量(从 10.1 % 到 17.6 %)。RE170/R600 混合物(15/85 %)被认为是 R600a 的潜在替代液,在各种工作条件下进行了测试,得出的结论是,它与 R600a 具有相同的冷却能力,但 COP 增量从 12.6 % 到 17.6 % 不等。

期刊介绍: The International Journal of Refrigeration is published for the International Institute of Refrigeration (IIR) by Elsevier. It is essential reading for all those wishing to keep abreast of research and industrial news in refrigeration, air conditioning and associated fields. This is particularly important in these times of rapid introduction of alternative refrigerants and the emergence of new technology. The journal has published special issues on alternative refrigerants and novel topics in the field of boiling, condensation, heat pumps, food refrigeration, carbon dioxide, ammonia, hydrocarbons, magnetic refrigeration at room temperature, sorptive cooling, phase change materials and slurries, ejector technology, compressors, and solar cooling. As well as original research papers the International Journal of Refrigeration also includes review articles, papers presented at IIR conferences, short reports and letters describing preliminary results and experimental details, and letters to the Editor on recent areas of discussion and controversy. Other features include forthcoming events, conference reports and book reviews. Papers are published in either English or French with the IIR news section in both languages.
