Patent number: 10731899Abstract: A variable refrigerant package air conditioner is shown that is easy to install in new construction with a unique base that causes collected mixture that overflows to drain outside the building. A control system is shown that has motors and compressor that are pulse width modulated so the air conditioner is infinitely variable while maintaining the highest possible power factor. Dehumidification of outside air occurs as it is mixed with inside air. By gradually approaching a temperature set point and even reheating after dehumidification, moisture is removed from the room.Type: GrantFiled: December 8, 2017Date of Patent: August 4, 2020Assignee: Friedrich Air Conditioning, LLCInventors: Kevin L. Eicher, George C. Cagle, Eduardo J. Guerrero, Bascom Clayton Cotner

Patent number: 9535408Abstract: A universal control system is provided for a room air conditioner or heat pump that has a number of sensor inputs. An electronic control system with a microcontroller and microcomputer are used to provide a large number of operations that can be performed by (1) manufacturer, (2) end users and (3) maintenance personnel. The manufacturer can load different versions of a software program to match the unit. The end user can program in a large number of different conditions or schedules the end user finds desirable, plus the end user is advised of maintenance requirements or faults. The maintenance personnel may perform diagnostics, determine fault history, upload improved or replacement software, as well as the numerous maintenance functions normally performed by maintenance personnel.Type: GrantFiled: April 19, 2010Date of Patent: January 3, 2017Assignee: Friedrich Air Conditioning Co., LtdInventors: David J.

Patent number: 8850832Abstract: A pre-charged heating/cooling system is shown for installation by unlicensed personnel. An outside unit includes an outside coil, outside fan, compressor and a reversing valve. An inside unit has an inside coil, inside fan for drawing air through the inside coil and discharging the conditioned air into the enclosed space, and a power cord connection. A cable sheath contains all connections from the inside unit to the outside unit with electrical connections being secured in position on the outside unit by a cover and a bracket. An expandable window sill holds and seals the cable sheath in a window opening.Type: GrantFiled: August 24, 2012Date of Patent: October 7, 2014Assignee: Friedrich Air Conditioning Co, Ltd.Inventors: David J. Lingrey, Charles Anthony Wheeler, Jr., Heath James Hoselton, Kevin L. Eicher

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.

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.
