Abstract
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.
Claims19
An absorption cycle apparatus, comprising:
- an absorption cooling system;
- and
- a working fluid comprising a metal halide, water, and a zwitterion additive, wherein the zwitterion additive comprises aspartic acid, 2,2′-[(phosphonomethyl)imino] diacetic acid, 3-[(2-hydroxyethyl)amino]-1-propanesulfonic acid, or combinations thereof.
An absorption cycle apparatus, comprising:
- an absorption cooling system;
- and
- a working fluid comprising lithium bromide, water, and aspartic acid.
A method of controlling crystallization in a working fluid of an absorption cycle apparatus comprising an absorption cooling system, comprising:
- introducing a zwitterion additive to the working fluid, wherein the working fluid comprises a metal halide and water, and the zwitterion additive comprises aspartic acid, 2,2′-[(phosphonomethyl)imino] diacetic acid, 3-[(2-hydroxyethyl)amino]-1-propanesulfonic acid, or combinations thereof.
