ABSTRACT:
To provide a safe, nontoxic, and high-performance mixed refrigerant for hot water supply/heating system which is prepared by mixing dimethyl ether with carbon dioxide and which does not deplete the ozone layer, has a low global warming potential, and permits low-pressure operation.A refrigerant composition for hot water supply/heating comprising 1 to 10% by mole of dimethyl ether and 99 to 90% by mole of carbon dioxide on the basis of the total number of moles of dimethyl ether and carbon dioxide.
