摘要
离子液体具有与传统的传热、储热材料相当,甚至更加优越的性质,如蒸气压低,储热密度高,物理和化学稳定性好,热传导性好,熔点低和可设计性等。因此,离子液体在太阳能集热、建筑节能、电力谷峰调控、低品位余热存储、吸附式热泵等领域具有良好的应用潜力。综述了离子液体在传热和储热中的应用研究进展,包括作为热传导液用于太阳能集热,作为吸附介质应用于制冷(制热),以及作为相变储热材料等。最后,指出离子液体的一些性质,如腐蚀性、毒性和长期稳定性等,也是离子液体在储热和传热应用中需要考察的问题。
Comparing with the traditional thermal storage and heat transfer materials,ionic liquids have an equal or better performance,such as low vapor pressure,high heat storage density,high physical and chemical stability,high thermal conductivity,low melting point,designable and so on.Therefore,the ionic liquids are of great potential for the application in solar energy collection,building energy conservation,electric power control,low-grade waste heat storage,adsorption heat pump and other areas.This paper summarized the application of ionic liquids in heat transfer and heat storage,including heat transfer fluids in the solar collectors as the absorption medium in cooling（heating）,as well as the phase change materials in heat storage.In addition,this article also pointed out that some properties,such as corrosive,toxic,etc.will be focused when these ionic liquids used in the process of thermal storage and heat transfer.
