摘要
简要回顾了传统空调的发展历史及工作原理。特别介绍了利用固态致冷剂的磁致变温效应的新技术。联合使用固态致冷剂和液态热交换剂必然会提高能量的使用效率,并且对环境的污染大大减小。在众多的温度调节系统中,空调系统使用的极为广泛,消耗了大量的电能,对环境的影响相对来讲也较大。这些现状导致了磁致变温效应的广泛研究,近年来不少部门有了初步的研发计划。此理论探讨表明,使用磁致变温空调的能耗成本要低于传统的空调。
The development and theory of traditional air-conditioner have been reviewed.Magnetic refrigeration is a new technology that makes use of the magnetocaloric effect of solid-state refrigerants.The combination of solid-state refrigerants,water-based heat transfer fluids will lead to environmentally desirable products with minimal contributions to global warming.The air conditioning application is one of the numerous applications of refrigeration technology,which provides the largest aggregate cooling power and use the greatest quantity of electric energy.The importance of the air conditioning application makes the establishment of cost targets for this application an essential feature of the RD plan for magnetic refrigeration technology.The theoretical study shows that the energy costs of magnetocaloric material lay well below the total manufactured costs for vapor compression based air conditioners.
