摘要
在传统的吸收式制冷系统中,最常用的工质对是LiBr/H_2O和NH_3/H_2O。然而,LiBr/H_2O工质对具有腐蚀和结晶的问题,NH_3/H_2O工质对则面临着NH_3本身有毒和需设置精馏装置等问题。离子液体作为一种新型的吸收剂可以有效地避免采用上述工质对所带来的弊端。研究和开发适合的离子液体/制冷剂工质对是吸收式制冷发展的一个重要方面。针对用于吸收式制冷系统的离子液体,从物性到循环特性的国内外研究进展进行了综述,并从应用于吸收式制冷系统的角度给出筛选工质对的建议。
In traditional absorption refrigeration systems,most commonly used working fluid pairs are LiBr/H2O and NH3/H2O.However,LiBr/H2O working fluid has problems of corrosion and crystallization,and NH3/H2O working fluid pair faces problem that NH3 is toxic and a rectification apparatus must be installed.As a new type of absorbent,ionic liquids can effectively avoid disadvantages of above-mentioned working fluids.Research and development of suitable ionic liquid/refrigerant working fluid pairs for real application is an important aspect of development of absorption refrigeration.This paper summarized research progress of ionic liquid-type working fluid pairs in domestic and overseas from basic physical properties to cycle performance,and gave suggestions for selection of working fluid pairs from point of application of ionic liquid in absorption refrigeration systems.
