Abstract
Refrigerant compositions are described, which can be used for example, in refrigeration, air conditioning, and/or heat pump systems which for example, can be incorporated into a heating, ventilation and air conditioning (HVAC) system or unit. The refrigerant composition includes an amount of a R125 refrigerant, an amount of a R32 refrigerant, and an amount of a R1234yf refrigerant, where the R32 refrigerant has higher flammability than the R125 refrigerant, and the R1234yf refrigerant has higher flammability than the R125 refrigerant.
