  • Publication number: 20250224161
    Abstract: 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.

  • Patent number: 12344457
    Abstract: 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.

  • Patent number: 12071582
    Abstract: 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.
