【摘要】 近年来,制冷剂对臭氧层的破坏和全球温室效应等环保问题日益突出,CO₂作为理想的制冷剂开始重新得到重视。本文介绍理论的跨临界CO₂蒸气压缩式制冷循环,对实验室现有CO₂跨临界制冷系统进行一系列研究,并与常用制冷剂的循环进行对比,认为CO₂制冷循环取代传统制冷循环应用于展示柜可大大提高制冷效率。更多还原

【Abstract】 In recent years,as the refrigerant damage to the ozone layer,global warming and other environmental problems have become increasingly prominent,CO₂ has started to be emphasized again as an ideal refrigerant.Introduces the general theory cycle of transcritical CO₂ vapor compression refrigeration,carries out a series of research based on a set of actual CO₂ transcritical refrigeration system and contrasts with the cycle used commonly refrigerant.Gets the conclusion that if CO₂ refrigeration cycle come to replace the traditional refrigeration cycle used in display cabinets,it can greatly enhance the refrigeration efficiency.更多还原
