A cooling system and a related method is presented. The cooling system includes a reservoir configured to selectively supply a cooling fluid; a circulation loop fluidly coupled to the reservoir, and configured to circulate the cooling fluid to and from the reservoir, and a heat exchanger thermally coupled to the circulation loop and configured to exchange heat with the cooling fluid. The reservoir includes a refrigerant and an anti-freeze additive. The anti-freeze additive is characterized by a lower critical solution temperature (LCST) such that when an operating temperature of the reservoir is greater than the LCST, the reservoir is configured to supply a cooling fluid including the refrigerant to the circulation loop; and when the operating temperature of the reservoir is lower than the LCST, the reservoir is configured to supply a cooling fluid including the refrigerant and the anti-freeze additive to the circulation loop.

An absorption cycle apparatus including a working fluid is presented. The working fluid includes a metal halide, water and a zwitterion additive, wherein the zwitterion additive includes an amino acid, 2,2'-[(phosphonomethyl)imino]diaceticacid, 3-[(2-hydroxyethyl)amino]-1-propanesulfonic acid, or combinations thereof. A method of controlling crystallization in a working fluid of an absorption cycle apparatus is also presented.
