白立光, 朱吉钦, 陈标华, et al. Applications of ionic liquids in heat transfer and heat storage process[J]. CIESC Journal, 2010, (12). DOI:
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.
