Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a refrigerant compsn. which does not cause phase separation in a wide temp. range from low to high temps. and can be used stably for a long term by incorporating a CO2 gas and at least one lubricating oil selected from among carbonate oils, ester oils, and ether oils into the same. SOLUTION: This refrigerant compsn. contains a CO2 gas and at least one lubricating oil selected from among carbonate oils pref. represented by formula 1, etc., ester oils pref. represented by formula II, and ether oils pref. represented by formula II, pref. in a wt. ratio of the gas to the oil of (2/98)-(98/2). In the formulas, R and R are each a 1-30C hydrocarbon group or the like; R is 1-12C alkyl; R and R are each H or 2-10C alkyl provided the sum of the numbers of carbon atoms of R to R is 4-16; R is a 2-30C n-hydric alcohol residue; n is 2-6; R is H, 1-10C alkyl, 2-10C alkenyl or alkynyl, or 6-10C aryl; R is 2-6C alkylene; R is R ; j is 1-40; and k is 1-6.
