Title:
ABSORPTION REFRIGERATOR AND DEHUMIDIFIER
Document Type and Number:
WIPO Patent Application WO/2016/152399
Kind Code:
A1
Abstract:
In a regenerator of an absorption refrigerator, a mixture of water and an ionic liquid is heated to transform the water to steam, thereby separating the water and the ionic liquid. A problem encountered in the prior art is that, as compared with sensible heat heating, such latent heat heating requires a temperature at or above the boiling point of the absorption solution, as well as a large amount of heat, and energy efficiency was therefore poor. The absorption refrigerator (10) is provided with: a mixer (30) for mixing a refrigerant and an ionic liquid in which the miscibility with the refrigerant changes with the temperature; a regenerator (40) for heating the mixture of the refrigerant and the ionic liquid mixed by the mixer, and separating the ionic liquid and the refrigerant through the difference in specific gravity thereof while the ionic liquid and the refrigerant remain in the liquid state; and an evaporator (20) for vaporizing the refrigerant separated by the regenerator, to generate cold energy.
