  • Ionic liquid additives for use as an absorbent in absorption chillers
    Patent number: 11608460
    Abstract: This invention relates to using an imidazolium bromide ionic liquid as an additive to lithium bromide in the absorbent for an absorption chiller. The imidazolium bromide ionic liquid is useful to increase the working region and to lower the risk of crystallization in an absorption chiller. The invention provides an absorption chiller comprising a mixture of a refrigerant and an absorbent, and the absorbent comprises lithium bromide and one or more imidazolium bromide ionic liquids.
    Type: Grant
