  • Systems and methods for heat recovery
    Patent number: 10386076
    Abstract: A filter unit heat exchanger is provided that may include a housing substantially surrounding a heat exchange assembly. Provided through the housing are one or more tortuous fluid flow paths used to direct airflow therethrough around portions of the heat exchange assembly for efficient operation. The tortuous path(s) may be provided by one or more nozzle openings on an input side of the housing and one or more diffuser openings on an output side of the housing, where the nozzle openings and diffuser openings are offset to cause desired airflow deflection. The filter unit may include desired symmetries to improve manufacturability and/or installation.
    Type: Grant

  • Systems and methods for heat recovery
    Patent number: 8728189
    Abstract: An embodiment of filter unit heat exchanger according to the present invention provides improved operability and manufacturability. Such device may include a housing substantially surrounding a heat exchange assembly. Provided through the housing are one or more tortuous fluid flow paths used to direct airflow therethrough around portions of the heat exchange assembly for efficient operation. The tortuous path(s) may be provided by one or more nozzle apertures on an input side of the housing and one or more diffuser apertures on an output side of the housing, where the nozzle apertures and diffuser apertures are offset to cause desired airflow deflection. The filter unit may include desired symmetries so as to improve manufacturability and/or installation.
