Compositions, systems, and methods for introducing lubricants, and additives, that are designed to work with environmentally friendly refrigerants into vehicle heat management systems including passenger compartment air conditioning (A/C) systems are disclosed. Methods for charging lubricants and specific additives using environmentally desirable (low GWP) refrigerant or refrigerant blend compositions into an environmentally friendly system, such as a system that uses HFO-1234yf, are also disclosed.

Compositions, system and methods for introducing POE lubricant into an electric (HEV, PHEV, EV) automotive air-conditioning/heating system or stationary air-conditioning/heating system or stationary refrigeration system using lower or low GWP refrigerant or refrigerant blends

A system and method for delivering a refrigerant to a refrigerant system. The system includes a distribution system comprising a distribution vessel, a transfer line, at least one pump, a distribution line and a distribution line branch arranged and disposed to transfer refrigerant from the distribution vessel to the refrigerant system. The system additionally includes a monitoring system comprising one or more sensors arranged and disposed to measure at least one distribution parameter within the distribution system and a recovery system arranged and disposed to selectively receive refrigerant based upon the refrigerant suitability for use in the refrigerant system.

Methods and containers for transporting, transferring, storing and using refrigerants

Disclosed are can taps for dispensing fluids from containers. The can tap has a housing with an inlet and an outlet, and a pin. The pin has a flow portion in fluidic communication with the inlet and the outlet of the housing. The pin may have a blunt depressor capable of operating a valve on the container. The flow portion of the pin allows fluid to flow between the housing and the pin. The can tap may have a gasket comprising a material having a hardness that prevents deformation of the container.

Refrigerant compositions including 2,3,3,3-tetrafluoropropene (HFO-1234yf) and propylene (R-1270) which exhibit near-azeotropic or azeotrope-like behavior. The refrigerant compositions exhibit a low global warming potential (GWP) and are non-ozone depleting. The refrigerant compositions are useful as a heating or cooling fluids in a variety of heating or cooling systems including heat pumps and other heating and cooling loops, in for example the automotive industry.

A multi-step method is disclosed for exchanging heat in a vapor compression heat transfer system having a working fluid circulating therethrough. The method includes the step of circulating a working fluid comprising a fluoroolefin to an inlet of a first tube of an internal heat exchanger, through the internal heat exchanger and to an outlet thereof. Also disclosed are vapor compression heat transfer systems for exchanging heat. The systems include an evaporator, a compressor, a dual-row condenser and an intermediate heat exchanger having a first tube and a second tube. A disclosed system involves a dual-row condenser connected to the first and second intermediate heat exchanger tubes. Another disclosed system involves a dual-row evaporator connected to the first and second intermediate heat exchanger tubes.

A method and apparatus for reclaiming refrigerant. The method includes transferring, an unreclaimed refrigerant composition, including one or more hydrofluoro olefins, from a source vessel to a receiving vessel and transporting the receiving vessel to a recycling center. The unreclaimed refrigerant composition is analyzed to determine the composition of the unreclaimed refrigerant composition sample. A target composition is determined, based on the analyzed unreclaimed refrigerant composition, and one or more treatments are determined, based on the target composition. The unreclaimed refrigerant composition is treated, with the one or more treatments, to form a reclaimed refrigerant composition having the composition of the reclaimed refrigerant composition is equal to the target composition.

Refrigerant compositions including 2,3,3,3-tetrafluoropropene (HFO-1234yf) and at least one of ethane (R-170) or propane (R-290) which exhibit near-azeotropic or azeotrope-like behavior. The refrigerant compositions exhibit a low global warming potential (GWP) and are non-ozone depleting. The refrigerant compositions are useful as a heating or cooling fluids in a variety of heating or cooling systems including heat pumps and other heating and cooling loops, in, for example, the automotive industry.
