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

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

Patent number: 9046309Abstract: A membrane cartridge is manufactured by repeatedly folding and joining two strips of membrane to form a cross-pleated cartridge with a stack of openings or fluid passageways configured in an alternating cross-flow arrangement. The cartridge can be modified for other flow configurations including co-flow and counter-flow arrangements. Methods for manufacturing such cross-pleated membrane cartridges, as well as apparatus used in the manufacturing process are described. Cross-pleated membrane cartridges comprising water-permeable membranes can be used in a variety of applications, including in heat and water vapor exchangers. In particular they can be incorporated into energy recovery ventilators (ERVs) for exchanging heat and water vapor between air streams being directed into and out of buildings.Type: GrantFiled: August 5, 2014Date of Patent: June 2, 2015Assignee: DPoint Technologies Inc.Inventors: Greg Montie, James Franklin Dean, Curtis Mullen, Robert Hill

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
