Patent number: 11913672Abstract: A dehumidification system for use with a dehumidification refrigerant to dry ambient air as part of a heating, ventilation, and air-conditioning (“HVAC”) system that includes an HVAC condenser as part of an HVAC refrigeration circuit. The dehumidification system may include a dehumidification refrigeration circuit separate from the HVAC refrigeration circuit. The dehumidification circuit may include a dehumidification compressor, a dehumidification condenser, a dehumidification expansion device, and a dehumidification evaporator. The dehumidification condenser may be positioned in close proximity to the HVAC condenser such that airflow across the HVAC condenser also flows across the dehumidification condenser. The dehumidification evaporator may be spaced apart from the dehumidification condenser such that airflow across the dehumidification evaporator does not flow across the dehumidification condenser.Type: GrantFiled: December 21, 2020Date of Patent: February 27, 2024Assignee: Goodman Global Group, Inc.Inventor: Geethakrishnan Vasudevan

Patent number: 8752399Abstract: A room air conditioner and/or heat pump is shown having a compressor, indoor coil, accumulator, expansion device and reversing valve for changing between a cooling cycle and a heating cycle. Intake louvers direct return air over the entire indoor coil for maximum heat transfer. Discharge louvers are curved upward to prevent short cycling while still being totally adjustable, up and down, right and left. Adjustment posts are anchored to a clip and are adjustable for right or left discharge of air and up or down discharge. Single handles control both the right or left discharge through a rear set of louvers and up or down discharge through a front set of louvers. A no circulation area prevents short cycling and curved edges prevent turbulence in air flow through louvers.Type: GrantFiled: January 22, 2010Date of Patent: June 17, 2014Assignee: Friedrich Air Conditioning Co., Ltd.Inventors: David J. Lingrey, Kevin L. Eicher, Geethakrishnan Vasudevan, David John Sayler

Patent number: 8640480Abstract: A room air conditioner and/or heat pump is shown with a main control and a user interface. The user interface is mounted on a user interface mount attached to the front of a main unit, but behind the bezel. The user interface mount is used to (a) insert or remove the main unit, (b) secure and protect wiring cables, (c) mount the user interface thereon, (d) direct a filter into position, (e) provide a slot for a fresh air slide, and (f) direct a bezel into position. A main control housing allows access there through to a main control circuit board, but prevents moisture from dripping on the main control circuit board. A dual filter element is located behind a double hinged door. Channels and flanges direct and secure the bezel into position.Type: GrantFiled: January 22, 2010Date of Patent: February 4, 2014Assignee: Friedrich Air Conditioning Co., Ltd.Inventors: David J. Lingrey, Kevin L. Eicher, Geethakrishnan Vasudevan, David John Sayler, Charles A. Wheeler, Jr., Patrick J. Bush, Eduardo J. Guerrero
