Patent number: 11300364Abstract: A method of forming a membrane panel configured to be secured within an energy exchange assembly may include forming an outer frame defining a central opening, and integrating a membrane sheet with the outer frame. The membrane sheet spans across the central opening, and is configured to transfer one or both of sensible energy or latent energy therethrough. The integrating operation may include injection-molding the outer frame to edge portions of the membrane sheet. Alternatively, the integrating operation may include laser-bonding, ultrasonically bonding, heat-sealing, or the like, the membrane sheet to the outer frame.Type: GrantFiled: June 4, 2019Date of Patent: April 12, 2022Assignee: Nortek Air Solutions Canada, Ine.Inventors: Blake Norman Erb, Stephen Harold Hanson, Mohammad Afshin

Patent number: 10132522Abstract: A counter flow air-to-air energy exchange assembly may include a plurality of air channel levels configured to allow air to pass therethrough. Each of the air channels may include a spacer layer having a plurality of modular spacer components secured together. At least two of the modular spacer components are identical in size and shape. The spacer layer includes a plurality of air channels. Each of the plurality of air channels extends from an air inlet to an air outlet.Type: GrantFiled: March 31, 2014Date of Patent: November 20, 2018Assignee: Nortek Air Solutions Canada, Inc.Inventors: Blake Norman Erb, Stephen Hanson, Mohammad Afshin

Patent number: 9901760Abstract: An air delivery system is configured to deliver air to an enclosed structure and may include at least one air channel configured to deliver air to or receive air from the enclosed structure, at least one component disposed within the at least one air channel, and at least one flame-blocking filter removably and adjustably secured within the at least one air channel. The at least one flame-blocking filter is configured to isolate the at least one component from a source of excessive temperature or flames. The at least one flame-blocking filter is configured to allow air to pass therethrough under normal operating conditions, and to block air and flames from passing therethrough when exposed to the excessive temperature or the flames.Type: GrantFiled: October 7, 2013Date of Patent: February 27, 2018Assignee: Nortek Air Solutions Canada, Inc.Inventors: Blake Norman Erb, Stephen Harold Hanson, Mohammad Afshin

Publication number: 20140262125Abstract: An energy exchange assembly may include one or more membrane panels. The one or more membrane panels may include a microporous membrane that has a pore size between 0.02 and 0.3 micrometers (?m) and a porosity between 45% and 80%. Optionally, the energy exchange assembly may further include a plurality of spacers that define air channels. The air channels may be configured to receive air streams therethrough. Each of the one or more membrane panels may be disposed between two spacers. The one or more membrane panels may be configured to allow a transfer of sensible energy and latent energy across the one or more membrane panels between the air channels.Type: ApplicationFiled: February 27, 2014Publication date: September 18, 2014Applicant: VENMAR CES, INC.Inventors: Blake Norman ERB, Stephen HANSON, Mohammad AFSHIN

Publication number: 20140190037Abstract: An energy exchange system is configured to provide dry supply air to an enclosed structure. The system may include an energy transfer device having a first portion configured to be disposed within a supply air flow path and a second portion configured to be disposed within a regeneration air flow path. The energy transfer device is configured to decrease a humidity level of supply air. The energy transfer device is configured to be regenerated with regeneration air. The system may also include a first heat exchanger configured to be disposed within the supply air flow path downstream from the energy transfer device and within the regeneration air flow path upstream from the second portion of the energy transfer device. The first heat exchanger is configured to transfer sensible energy between the supply air and the regeneration air. The supply air is configured to be supplied to the enclosed structure after passing through the energy transfer device and the first heat exchanger.Type: ApplicationFiled: January 9, 2013Publication date: July 10, 2014Applicant: Venmar CES, Inc.Inventors: Blake Norman Erb, Mohammad Afshin
