【摘要】 通根据个体冷却的实际需求,采用美国ASPEN公司研制的高性能微型转子式制冷压缩机,使用微型电子膨胀阀,平行流冷凝器,并独立开发研制了微通道的"板翅式"蒸发器,在此基础上研制了新型基于蒸汽压缩制冷循环的个体冷却系统,并对系统性能进行了试验研究。微型制冷装置重量2.75kg,工作可靠、运行平稳。实验结果表明,研制的微型制冷装置,在环境温度55℃、提供的冷水温度为24℃的条件下,制冷量达到215W,COP可达1.2;真实热环境条件下,试验个体使用此新型个体冷却系统,热耐受时间显著延长,达到了设计的目的和要求。更多还原

【Abstract】 In this paper a miniature and ultraportable vapor-compression refrigeration system for personal cooling has been developed and tested.To meet the demand of portability,several key miniature components have been utilized or developed such as a miniature compressor,a miniature electronic expansion valve and a microchannel plate-fin evaporator.In this way,the total weight of the miniature refrigerator is less than 3.0kg.The system is tested under various conditions and the performance curves are presented.It is shown that the miniature refrigeration system can yield a cooling capacity of 215 watts with COP 1.2 at ambient temperature of 55°C with cold water temperature of 24°C to the cooling vest,which is high enough to meet the cooling demand for a person who works in that high temperature circumstances.………更多还原
