Patent number: 11906199Abstract: A heat and humidity exchanger comprises panels made up of membrane sheets attached on either side of a separator. Channels extend across each panel between the separator and the membrane sheets. The panels are much stiffer than the membrane sheets. Panels are stacked in a spaced apart relationship to provide an ERV core. Spacing between adjacent panels may be smaller than a thickness of the panels.Type: GrantFiled: January 12, 2023Date of Patent: February 20, 2024Assignee: CORE ENERGY RECOVERY SOLULTIONS INC.Inventors: Curtis Warren Mullen, David Erwin Kadylak, Christopher Robert Barr, James Franklin Dean, Guy Timothy Pearson

Patent number: 11506056Abstract: A rotary machine, for directing a quantity of fluid from an inlet to an outlet, comprises one or more elliptical or near-elliptical rotors having planetary rotation within a housing. The interior cavity of the housing comprises an inverse apex region that is in contact with the rotor during its rotation. In various embodiments the rotor and housing can be symmetric or asymmetric in cross-section. Features are described that can improve the operation of the machine for various end-use applications. Such features include cut-outs that are fluidly connected to the inlet or outlet ports of the machine, mechanisms for reducing variation in output flow rate from the rotary machine, linings for the interior cavity of the housing, pressure relief mechanisms, dynamic apex seals and other sealing mechanisms.Type: GrantFiled: October 12, 2020Date of Patent: November 22, 2022Assignee: Rotoliptic Technologies IncorporatedInventors: Greg John Montie, Curtis Warren Mullen

Publication number: 20190285289Abstract: A heat and humidity exchanger has example application in exchanging heat and water vapor between fresh air entering a building and air being vented from the building. The heat and humidity exchanger has a self-supporting core formed from layered sheets of a moisture-permeable material. Plenums are arranged to direct fluid streams into and out of the core. The plenums may be on opposing sides of the core to permit counterflow exchange of heat and water vapor.Type: ApplicationFiled: April 24, 2019Publication date: September 19, 2019Inventors: James Franklin DEAN, David Erwin KADYLAK, Ryan Nicholas HUIZING, Jordan Benda BALANKO, Curtis Warren MULLEN

Publication number: 20140326432Abstract: A heat and humidity exchanger has example application in exchanging heat and water vapour between fresh air entering a building and air being vented from the building. The heat and humidity exchanger has a self-supporting core formed from layered sheets (710, 720) of a moisture-permeable material. Plenums (750) are arranged to direct fluid streams into and out of the core. The plenums (750) may be on opposing sides of the core to permit counterflow exchange of heat and water vapour. The plenums (750) are attached to the core along opposite edges of the sheets (710, 720).Type: ApplicationFiled: December 19, 2012Publication date: November 6, 2014Applicant: dPoint Technologies Inc.Inventors: James Franklin Dean, David Erwin Kadylak, Ryan Nicholas Huizing, Jordan Benda Balanko, Curtis Warren Mullen
