Abstract
The refrigerant composition includes R1150 refrigerant, R170 refrigerant, and a third refrigerant. The third refrigerant is one of R1132a refrigerant and R1270 refrigerant. A method of making a refrigerant composition for an HVACR system includes mixing an amount of R1150 refrigerant, an amount of R170 refrigerant, and an amount of the third refrigerant. A method of retrofitting an existing refrigerant composition in an HVACR system includes adding at least one of R1150 refrigerant, R170 refrigerant, and a third refrigerant to the existing refrigerant composition to obtain a retrofit refrigerant composition.
