    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: 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 refrigerant composition includes R1132(E) refrigerant, a second refrigerant, and a third refrigerant. The second refrigerant is one of R1234ze(E) refrigerant, R134a refrigerant, or R1234yf refrigerant. The third refrigerant is one of R32 refrigerant, R1132a refrigerant, R1123 refrigerant, and CO2. The refrigerant composition has a GWP of at or about or less than 750. A method of making a refrigerant composition for an HVACR system includes mixing an amount of R1132(E) refrigerant, an amount of a second refrigerant, and an amount of a third refrigerant. A method of retrofitting an HVACR system having an existing refrigerant composition includes adding at least one of R1132(E) refrigerant, a second refrigerant, and a third refrigerant to the existing refrigerant composition to obtain a retrofit refrigerant composition.

    Abstract: A refrigerant composition includes R1225ye(E) refrigerant, a second refrigerant that is one of R1234ze(E) refrigerant and R32 refrigerant, and a third refrigerant that is one of R227ea refrigerant, R125 refrigerant, and R1234yf refrigerant. The refrigerant composition has a GWP of at or less than about 2000. A method of making a refrigerant composition includes mixing at least an amount of R1225ye(E) refrigerant, an amount of a second refrigerant, and an amount of a third refrigerant to obtain a refrigerant composition that has a GWP of at or about or less than 2000. A method of retrofitting a refrigerant composition in an HVACR system includes adding an amount of at least one refrigerant to a refrigerant composition to produce a retrofit refrigerant composition that includes R1225ye(E) refrigerant, a second refrigerant, and a third refrigerant.

    Abstract: A dehumidifying air handling unit for a heating, ventilation, air conditioning, and refrigeration (HVACR) system includes a housing, a hollow desiccant drum configured to rotate within the housing, and a heat exchanger disposed within the hollow desiccant drum. The hollow desiccant drum includes channels that extend through a sidewall that surrounds an interior space. A desiccant is provided in the channels. The heat exchanger is configured to cool air flowing through the interior space of the hollow desiccant drum. A method of conditioning air includes rotating a hollow desiccant drum within a housing and directing the air to pass through the hollow desiccant drum. The air passing through the hollow desiccant drum includes cooling, with the heat exchanger, the air in an interior space of the hollow desiccant drum, and adsorbing, with a desiccant, moisture from the air cooled by the heat exchanger

    Abstract: A heat transfer circuit that includes a main flow path for a working fluid that extends through a compressor, a condenser, an expander, and an evaporator. The working fluid includes CF3I. The heat transfer circuit also includes an additive stream configured to supply additive for the CF3I to the working fluid in the main flow path based on a discharge temperature of the compressor. A method for operating a heat transfer circuit that includes directing a working fluid including CF3I through a main flow path of the heat transfer circuit. The method also includes changing a concentration of additive for the CF3I based on a discharge temperature of the working fluid from the compressor.
