PURPOSE:An absorption refrigerant composition, obtained by adding a specific phosphite compound and a phosphate compound secondarily to a fluorohydrocarbon and a polar organic solvent, having high-temperature stability and rust preventing effect on a coexisting metal, and usable for absorption refrigerators and heat pumps. CONSTITUTION:An absorption refrigerant composition obtained by adding (A) a phosphite compound expressed by the formula (R1O)(R2O)(R3O)P and (B) a phosphate compound expressed by the formula (R4O)(R5O)(R6O)PO (R1-R6 are H, alkyl, alkenyl, phenyl, etc.) secondarily in 0.05-0.5wt% respective phosphorus concentrations to a composition consisting of a fluorohydrocarbon and a polar organic solvent. |
