Abstract
[Problems] To provide a refrigerant which is obtained by mixing a refrigerant, dimethyl ether, and carbon dioxide and which has such excellent performances that it does not cause ozonosphere depletion, has extremely low global warming potential, and is safe and nontoxic. [Means for solving problems] The refrigerant composition for refrigerating machines contains 1-10 mol % dimethyl ether and 99-90 mol % carbon dioxide.
Claims4
