Abstract
A composition for absorption refrigeration which comprises a fluorinated hydrocarbon refrigerant, an amide or glycol ether solvent serving as an absorption liquid, and a phosphite stabilizer. The stabilizer is used in an amount of 0.05 to 0.5 wt % of the absorption liquid calculated as phosphorus, within which range the phosphite stabilizer can suitably protect the refrigerant and the absorption liquid from deteriorating and decomposing at high operation temperatures.
