Abstract
Methods of using refrigerant compositions and systems thereof are described. In particular, methods of using refrigerant compositions and systems thereof, include refrigerant compositions including a two component blend. One of the components is a refrigerant blend that, when first combined, is considered an azeotropic blend, azeotrope, near azeotropic, or the like. This component is one component of the two components of the resulting refrigerant composition, which is combined with a second component being another refrigerant.
