An absorbent solution for an absorption refrigeration apparatus is composed of water as a refrigerant and an absorbent. The absorbent is a mixture of at least three lithium compounds selected from the group consisting of lithium bromide, lithium iodide, lithium chloride, and lithium nitrate. The mixture ratio of, for example, lithium bromide to lithium iodide to lithium chloride in the absorbent is 1:0.1-1.0:0.05-0.50. Therefore, since absorption temperature sufficiently higher than crystallization temperature can be achieved, neither lithium halide nor lithium nitrate is precipitated in the absorbent solution during the operation cycle of the refrigeration apparatus. |
