Patent number: 11578881Abstract: 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: October 23, 2020Date of Patent: February 14, 2023Assignee: CORE Energy Recovery Solutions Inc.Inventors: Curtis Warren Mullen, David Erwin Kadylak, Christopher Robert Barr, James Franklin Dean, Guy Timothy Pearson

Patent number: 10866001Abstract: Water vapor transport membranes for ERV and other water vapor transport applications are provided. The membranes include a substrate and an air impermeable selective layer coated on the substrate, the selective layer including a cellulose derivative and a sulfonated polyaryletherketone. In some embodiments the sulfonated polyaryletherketone is in a cation form and/or the selective layer includes sPEEK and CA in an sPEEK:CA (wt.:wt.) ratio in the range of about 7:3 to 2:3. Methods for making such membranes are provided. The methods include applying a coating solution/dispersion to a substrate and allowing the coating solution/dispersion to dry to form an air impermeable selective layer on the substrate, the coating solution/dispersion including a cellulose derivative and a sulfonated polyarylether ketone. In some embodiments the sulfonated polyaryletherketone is in a cation form and/or the coating solution/dispersion includes sPEEK and CA in an sPEEK:CA (wt.:wt.) ratio in the range of about 7:3 to 2:3.Type: GrantFiled: October 17, 2018Date of Patent: December 15, 2020Assignee: CORE Energy Recovery Solutions Inc.Inventors: Ryan Nicholas Huizing, Hao Chen, Frankie Kin Bong Wong

Patent number: 10569230Abstract: An air-impermeable water vapor transport membrane comprises an active layer on a microporous polymeric substrate. The active layer comprises a polyethylene-oxide containing copolymer and a polar protic solvent in an amount of about 3% to about 100% of copolymer weight in the active layer. Molecules of the protic solvent are bonded to the copolymer. The polar protic solvent reduces temperature-dependent variability in the water-vapor permeability of the membrane.Type: GrantFiled: May 30, 2016Date of Patent: February 25, 2020Assignee: CORE Energy Recovery Solutions Inc.Inventors: Ryan Nicholas Huizing, Hao Chen, Frankie Kin Bong Wong

Patent number: 10317095Abstract: 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: GrantFiled: June 16, 2016Date of Patent: June 11, 2019Assignee: CORE Energy Recovery Solutions Inc.Inventors: James Franklin Dean, David Erwin Kadylak, Ryan Nicholas Huizing, Jordan Benda Balanko, Curtis Warren Mullen
