Publication number: 20240027094Abstract: Systems and methods for controlling conditions in an enclosed space, such as a data center, or for providing cooling to a device, can include using a Liquid-to-Air Membrane Energy Exchanger (LAMEE) as an evaporative cooler. The LAMEE or exchanger can cool water to the outdoor air wet bulb temperature in a cooling system disposed outside of the enclosed space or device. The reduced-temperature water can be delivered to the enclosed space or device or can cool a coolant that is delivered to the enclosed space or device. The air in the enclosed space, or one or more components in the enclosed space, can be cooled by delivering the reduced-temperature water or coolant to the enclosed space, rather than moving the supply air from the enclosed space to the cooling system. In an example, the cooling system can include one or more cooling coils, upstream or downstream of the LAMEE.Type: ApplicationFiled: September 29, 2023Publication date: January 25, 2024Inventors: Davood Ghadiri Moghaddam et al., Philip Paul LePoudre, Manfred Gerber

Publication number: 20220003437Abstract: Conditioning systems and methods for providing cooling to a heat load can include an evaporative cooler arranged in a scavenger plenum with a pre-cooler upstream and a recovery coil downstream of the evaporative cooler. Outdoor or scavenger air can be conditioned in the evaporative cooler such that the conditioned scavenger air can provide cooling to a cooling fluid circulating through the recovery coil. The reduced-temperature cooling fluid can provide liquid cooling or air cooling for an enclosed space (for example, a data center) or for one or more devices that are enclosed or open to the atmosphere. Given the design and arrangement of the pre-cooler, evaporative cooler and recovery coil in the plenum, the system can operate in multiple modes. The pre-cooler can be configured to circulate a cooling fluid to condition the scavenger air. The pre-cooler fluid circuit can be coupled or decoupled from a process cooling fluid circuit.Type: ApplicationFiled: July 13, 2021Publication date: January 6, 2022Inventors: Philip Paul LePoudre, Manfred Gerber, Davood Ghadiri Moghaddam

Patent number: 11015845Abstract: Systems and methods for controlling temperature in an enclosed space can include an air-to-air heat exchanger (AAHX) and a direct evaporative cooler (DEC). The DEC can be located in a scavenger or outdoor air stream such that the DEC cools the outdoor air, which is then used to cool or reject heat from a process air stream passing through the AAHX. In an example, the AAHX can be a sensible wheel. In another example, the AAHX can be a counter-flow flat plate. The system can operate in various modes, including an economizer mode and an evaporation mode, depending, in part, on the outdoor air conditions and a load on the system. In some examples, the system can include a DX coil to provide additional cooling to the process air in another operating mode.Type: GrantFiled: December 21, 2018Date of Patent: May 25, 2021Assignee: Nortek Air Solations Canada, Inc.Inventors: Davood Ghadiri Moghaddam, Philip Paul LePoudre, Manfred Gerber

Patent number: 10962252Abstract: Systems and methods are disclosed herein for a three-fluid liquid-to-air membrane energy exchanger (LAMEE) to condition air (a first overall fluid). A liquid panel assembly used in the LAMEE can include a first fluid circuit for a first cooling fluid (a second overall fluid) and a second fluid circuit for a second cooling fluid (a third overall fluid). The first cooling fluid, also referred to herein as a desiccant, can be configured to circulate through the liquid panel assembly and condition an air stream passing through the LAMEE. The second cooling fluid, also referred to herein as a coolant, can be configured to also circulate through the panel assembly and reject heat from the first cooling fluid. The second cooling fluid can increase the cooling capacity and overall performance of the LAMEE. The first and second cooling fluids can be separate from each other during circulation through the panel assembly.Type: GrantFiled: June 24, 2016Date of Patent: March 30, 2021Assignee: Nortek Air Solutions Canada, Inc.Inventors: Philip Paul LePoudre, Davood Ghadiri Moghaddam, Manfred Gerber

Patent number: 10834855Abstract: Systems and methods for controlling conditions in an enclosed space can include an integral make-up air system that can be arranged in the interior of the housing for an air conditioning system that uses scavenger air in an air-to-air heat exchanger (AAHX) to condition process air from an enclosed space. The make-up air system can take replenishment air from outside the air conditioning system and deliver it into the process air stream. The make-up air system can include at least one heating or cooling device to condition the replenishment air before the replenishment air mixes with the process air. In an example, the make-up air system can include a DX coil to selectively cool and dehumidify the replenishment air. The make-up air system can include a humidifier arranged in the flow path of process air between the process air inlet and the AAHX to selectively add humidity to the process air.Type: GrantFiled: January 8, 2016Date of Patent: November 10, 2020Assignee: Nortek Air Solutions Canada, Inc.Inventors: Davood Ghadiri Moghaddam, Philip Paul LePoudre, Manfred Gerber, Stephane Vivier
