摘要： Methods, systems and apparatuses are described that are directed to on-site recovery and/or repurposing of refrigerant, where an original refrigerant is converted into a refrigerant different from the original refrigerant. The refrigerant different from the original refrigerant can have relatively lower global warming potential (GWP) than the original refrigerant. The recovery and/or repurposing can be implemented for example in a refrigeration circuit, such as for example in general cooling and/or heating applications, which may be embodied in a heating, venting, and air conditioning (HVAC) system and/or unit, in a transport refrigeration system and/or unit, as well as in commercial, residential and/or industrial cooling and/or heating applications.

摘要： Refrigeration systems with a purge for removing non-condensables from the refrigerant and an acid filter for remove acid from the refrigerant are provided. The acid filter can be operatively connected to the purge. Optionally, the purge can include a separating device for separating non-condensable gases from condensable refrigerant gases and an acid filter is provided to remove acid from the condensable refrigerant gases.

摘要： There is described a system comprising an interior space (22), a heating, ventilation, air conditioning, and refrigeration (HVACR) system (20) and one or more refrigerant sensors (56, 100, 108). The HVACR system (20) includes an indoor system (20A) disposed within the interior space (22), the indoor system (20A) including an air handling unit (24), one or more refrigerant lines (26, 28) having a brazed, soldered, or mechanical joint (54), an enclosure (48) including a housing (50) that encloses the brazed, soldered, or mechanical joint (54), and a refrigerant circuit (10). A refrigerant in the refrigerant circuit (10) includes a flammable refrigerant. The HVACR system (20) is configured to enable one or more of a blower (30) of the air handling unit (24) and a fan of the interior space (22) in response to the one or more refrigerant sensors (56, 100, 108) detecting a refrigerant leak.

摘要： 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.

摘要： 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.
