Abstract: A refrigeration system is disclosed. The system includes a compressor, a condenser, an expansion device, and an evaporator fluidly connected to form a refrigeration circuit. A refrigerant composition including an environmentally-suitable chiller refrigerant that has a 100 year direct global warming potential (GWP) of less than 150 is included. The refrigerant composition includes a mixture including R-1336mzz-(Z) and R-1130-(E), wherein an amount of R-1336mzz-(Z) in the mixture is in a range from at or about 69% by weight to at or about 81% by weight, and an amount of R-1130-(E) in the mixture is in a range from at or about 31% by weight to at or about 19% by weight.

Abstract: 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.

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 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.

Abstract: Heat is recovered from a heat source to heat water to high temperatures. Apparatuses, systems and methods are described to heat water to a high temperature by using heat, such as may be considered in some instances as waste heat, recovered from a heat source. The methods, systems, and apparatuses described utilize low pressure refrigerant(s) as a fluid to provide a refrigeration cycle that utilizes a source of heat to heat water to a high temperature. The refrigeration cycle can be with or without a cascade cycle. The refrigerant cycle in some examples uses an oil free compressor.
