Publication number: 20230392872Abstract: A liquid panel assembly configured to be used with an energy exchanger may include a support frame having one or more fluid circuits and at least one membrane secured to the support frame. Each of the fluid circuits may include an inlet channel connected to an outlet channel through one or more flow passages. A liquid is configured to flow through the fluid circuits and contact interior surfaces of the membrane(s). The fluid circuits are configured to at least partially offset liquid hydrostatic pressure with friction loss of the liquid flowing within the fluid circuits to minimize, eliminate, or otherwise reduce pressure within the liquid panel assembly.Type: ApplicationFiled: June 30, 2023Publication date: December 7, 2023Inventors: Philip Paul LePoudre, Kenneth Paul Coutu, Howard Brian Hemingson

Patent number: 11761645Abstract: Certain embodiments provide an energy exchange system that includes a supply air flow path, an exhaust air flow path, an energy recovery device disposed within the supply and exhaust air flow paths, and a supply conditioning unit disposed within the supply air flow path. The supply conditioning unit may be downstream from the energy recovery device. Certain embodiments provide a method of conditioning air including introducing outside air as supply air into a supply air flow path, pre-conditioning the supply air with an energy recovery device, and fully-conditioning the supply air with a supply conditioning unit that is downstream from the energy recovery device.Type: GrantFiled: February 5, 2021Date of Patent: September 19, 2023Assignee: Nortek Air Solutions Canada, Inc.Inventors: Kenneth Paul Coutu, Howard Brian Hemingson, Manfred Gerber

Patent number: 11598534Abstract: An air delivery system may include a housing, a first liquid-to-air membrane energy exchanger (LAMEE), and a desiccant storage tank. The housing includes a supply air channel and an exhaust air channel. The first LAMEE may be an exhaust LAMEE disposed within an exhaust air channel of the housing. The exhaust LAMEE is configured to receive the outside air during a desiccant regeneration mode in order to regenerate desiccant within the exhaust LAMEE. The desiccant storage tank is in communication with the exhaust LAMEE. The exhaust LAMEE is configured to store regenerated desiccant within the desiccant storage tank. The regenerated desiccant within the desiccant storage tank is configured to be tapped during a normal operation mode.Type: GrantFiled: February 7, 2020Date of Patent: March 7, 2023Assignee: Nortek Air Solutions Canada, Inc.Inventors: Kenneth Paul Coutu, Cam Forman, Philip Paul LePoudre, Blake Norman Erb, Howard Brian Hemingson, Manfred Gerber

Publication number: 20220003436Abstract: An energy exchanger is provided. The exchanger includes a housing having a front and a back. A plurality of panels forming desiccant channels extend from the front to the back of the housing. Air channels are formed between adjacent panels. The air channels are configured to direct an air stream in a direction from the front of the housing to the back of the housing. A desiccant inlet is provided in flow communication with the desiccant channels. A desiccant outlet is provided in flow communication with the desiccant channels. The desiccant channels are configured to channel desiccant from the desiccant inlet to the desiccant outlet in at least one of a counter-flow or cross-flow direction with respect to the direction of the air stream.Type: ApplicationFiled: June 11, 2021Publication date: January 6, 2022Inventors: Robert Besant, Carey Simonson, Blake Norman Erb, Howard Brian Hemingson
