Refrigerant composition
View Patent ↗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.
1. A method of using a refrigerant composition for a hot water supply/heating system, the method comprising utilizing a composition that comprises 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 as a refrigerant in the hot water supply/heating system.
2. A method of using a refrigerant composition for a hot water supply/heating system, the method comprising utilizing a composition that comprises 3 to 8% by mole of dimethyl ether and 97 to 92% by mole of carbon dioxide on the basis of the total number of moles of dimethyl ether and carbon dioxide as a refrigerant in the hot water supply/heating system.
