| description | The present invention relates to a refrigerant composition comprising at least about 98.5% by weight of the following three compounds, with each compound being present in the following relative percentages: 33.0% to 45% by weight difluoromethane (HFC-32); 48.5% to 67.0% by weight of 2,3,3,3-tetrafluoropropene (HFO-1234yf); and 1.0% to 6.0% by weight fluoroethane (HFC-161 ), and to the use of the refrigerant in a heat exchange system, including air conditioning, refrigeration applications and heat pump applications and to the use of such compositions as a replacement of the refrigerant R-410A or R-32 or R-454B for heating and cooling applications.
La présente invention concerne une composition réfrigérante comprenant au moins environ 98,5 % en poids des trois composés suivants, chaque composé étant présent dans les pourcentages relatifs suivants : de 33,0 % à 45 % en poids de difluorométhane (HFC-32) ; de 48,5 % à 67,0 % en poids de 2,3,3,3-tétrafluoropropène (HFO-1234yf) ; et de 1,0 % à 6,0 % en poids de fluoroéthane (HFC-161), et l'utilisation du réfrigérant dans un système d'échange de chaleur, comprenant des applications de climatisation, des applications de réfrigération et des applications de pompes à chaleur et l'utilisation de telles compositions en remplacement du réfrigérant R-410A ou R-32 ou R-454B pour des applications de chauffage et de refroidissement. |
