Abstract: A method of converting a refrigerant includes recovering a refrigerant from a refrigeration unit with an evacuation pump and containing the recovered refrigerant in a container. The method also includes converting the recovered refrigerant. The converted refrigerant is different from the recovered refrigerant. A system for converting a refrigerant includes an evacuation pump, a container, and one or more refrigerant containers. The evacuation pump and container are configured to recover a refrigerant from a refrigeration unit. The one or more refrigerant containers deliver one or more refrigerant components into the container to convert the recovered refrigerant.

Abstract: Refrigerant compositions for an HVACR system that includes R1123, R32 and at least one more refrigerant. The refrigerant composition has a reduced GWP of about or less than 1500. Some of the refrigerant composition may be suitable for replacing R410A, R32, and/or R22. Methods for making the refrigerant composition including mixing an amount of R1123, and amount of R32, and an amount of at least one more refrigerant. Methods of retrofitting an existing refrigerant composition include adding an amount of at least one refrigerant to an existing refrigerant composition to produce a retrofitted refrigerant composition. The retrofitted refrigerant composition includes at least R1123 and R32.

Abstract: A detection system and method of detection directed towards the detection of refrigerant leaking from a refrigerant circuit in a heating, ventilation, air condition, and refrigeration (HVACR) system. The system including a refrigerant circuit utilizes a mixture of working fluid and an additive. The system also includes a detection device that can detect the additive when external to the refrigerant circuit. A method of detecting leaking refrigerant includes adding a detectable fluid to a refrigerant circuit.

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.

Abstract: A system and method of retrofitting a heating, ventilation, air conditioning, and refrigeration system (HVACR) including one or more brazed, soldered, or mechanical connections between refrigerant lines is disclosed. The method includes removing a refrigerant from the HVACR system. The refrigerant that is removed is a non-flammable refrigerant. An enclosure is installed over the one or more brazed, soldered, or mechanical connections between refrigerant lines. A refrigerant is added to the HVACR system. The refrigerant being added has a global warming potential (GWP) that is relatively lower than the refrigerant removed from the HVACR system. The refrigerant being added has a relatively higher flammability than the refrigerant removed from the HVACR system.
