Patent number: 10634392Abstract: A heat pump system for conditioning regeneration air from a space is provided. The heat pump system is operable in a winter mode and/or a summer mode, and may be selectively operated in a defrost mode or cycle. During a defrost mode, hot refrigerant may be used to directly and sequentially defrost the regeneration air heat exchanger. A compressor may be configured to be overdriven during a defrost cycle.Type: GrantFiled: September 20, 2017Date of Patent: April 28, 2020Assignee: Nortek Air Solutions Canada, Inc.Inventors: David Martin Wintemute, Mathieu Philippe Beliveau

Patent number: 10274210Abstract: A heat pump system for conditioning outside air supplied to a building is provided. The system includes a pre-processing module that receives and cools air when the system is operating in a summer mode. A supply air heat exchanger is in flow communication with the pre-processing module. The supply air heat exchanger receives and cools air from the pre-processing module in the summer mode. A processing module is in flow communication with the supply air heat exchanger. The processing module receives and dehumidifies saturated air from the supply air heat exchanger in the summer mode.Type: GrantFiled: August 27, 2010Date of Patent: April 30, 2019Assignee: Nortek Air Solutions Canada, Inc.Inventor: David Martin Wintemute

Publication number: 20180252487Abstract: An energy exchange system includes a supply flow path including a central sub-path connected to a bypass sub-path that is, in turn, connected to a delivery sub-path that connects to the enclosed structure. A sensible heat exchanger configured to condition the supply air is disposed within the central sub-path. The bypass sub-path connects to the central sub-path upstream from the sensible heat exchanger within the central sub-path. A first coil configured to further condition the supply air is disposed within the central sub-path downstream from the sensible heat exchanger. A bypass damper is disposed within the bypass sub-path. The bypass damper is configured to be selectively opened and closed. The bypass damper allows at least a portion of the supply air to pass through the bypass sub-path into the delivery sub-path and bypass the sensible heat exchanger and the first coil when the bypass damper is open.Type: ApplicationFiled: April 30, 2018Publication date: September 6, 2018Inventors: David Martin Wintemute, Remi Fortin

Patent number: 9920940Abstract: A rotary wheel assembly is configured for use with a system for conditioning air to be supplied to an enclosed structure. The rotary wheel is configured to be positioned within a supply air stream and an exhaust air stream. The assembly includes a cassette frame, a wheel rotatably secured within the cassette frame, and a self-adjusting seal subassembly configured to maintain sealing engagement with respect to a surface of the wheel. The self-adjusting seal subassembly includes at least one seal member.Type: GrantFiled: December 5, 2011Date of Patent: March 20, 2018Assignee: Nortek Air Solutions Canada, Inc.Inventors: Blake Norman Erb, Manfred Gerber, Maury Brad Wawryk, David Martin Wintemute, Paul Lorenzo Pieper

Patent number: 9885486Abstract: A heat pump system for conditioning air supplied to a space is provided. The system includes a pre-processing module that pre-conditions supply air. A supply air heat exchanger is in flow communication with the pre-processing module. The supply air heat exchanger receives air from the pre-processing module and at least one of heats or cools the air from the pre-processing module. A processing module is in flow communication with the supply air heat exchanger. The processing module receiving and conditioning air from the supply air heat exchanger. A regeneration air heat exchanger is provided to at least one of heat or cool regeneration air. The regeneration air heat exchanger and the supply air heat exchanger are fluidly coupled by a refrigerant system.Type: GrantFiled: October 18, 2011Date of Patent: February 6, 2018Assignee: Nortek Air Solutions Canada, Inc.Inventor: David Martin Wintemute
