Abstract
The invention relates to compositions that can be used as refrigerants. More specifically, the invention relates to compositions having a very low contribution to the greenhouse effect, which can be used in the cooling and production of conditioned air. The GWP of the inventive compositions is preferably at most equal to 150.
Claims1
A composition comprising 30% to 80% by weight of difluoromethane, 10% to 30% by weight carbon dioxide, and 20% to 35% by weight ethylene glycol diacetate, said ethylene glycol diacetate having a boiling point at atmospheric pressure of greater than 60° C. a melting point at atmospheric pressure<−20° C. and/or a flash point>70° C.
