COMPOSITION FOR ABSORBING CARBON DIOXIDE, REFRIGERANT COMPOSITION CONTAINING SAME, AND COOLING SYSTEM USING SAME

Document Type and Number:

WIPO Patent Application WO/2017/082664

Kind Code:

A1

Abstract:

The present invention provides a composition for absorbing carbon dioxide comprising an ionic liquid mixture in which a second ionic liquid having a solid phase in a temperature range of -20 to 120 ℃ is present in a dissolved state in a first ionic liquid having a liquid phase in a temperature range of -20 to 120 ℃. The composition for absorbing carbon dioxide is an absorbent of an absorption cooling system, and may function as a working fluid constituting a refrigerant composition in a co-fluid cooling system. The ionic liquid composition maximizes an effect of absorbing carbon dioxide and can ultimately improve the cooling efficiency of a cooling system which adopts the same.
