  • HVAC systems with evaporator bypass and supply air recirculation and methods of using same
    Patent number: 11859849
    Abstract: An HVAC system includes an evaporator coil disposed between a return air duct and a supply air duct. The system includes a compressor fluidically connected to the evaporator coil, and a blower for providing a flow of air through the HVAC system. A controller determines an operating mode of the HVAC system.
    Type: Grant
    Filed: October 19, 2022
    Date of Patent: January 2, 2024
    Assignee: Lennox Industries Inc.
    Inventors: Rakesh Goel, Vijay Sathyamurthi

  • HVAC systems with evaporator bypass and supply air recirculation and methods of using same
    Patent number: 11549714
    Abstract: An HVAC system includes an evaporator coil disposed between a return air duct and a supply air duct. The system includes a compressor fluidically connected to the evaporator coil, and a blower for providing a flow of air through the HVAC system. The HVAC system includes a supply air recirculation line with a recirculation damper and an evaporator bypass line with a bypass damper. A controller of the HVAC determines a recirculation portion of a flow of air and causes the recirculation damper to move to divert the recirculation portion to the recirculation line, so the air recirculates through the HVAC system. The controller determines a bypass portion of a flow of air and causes the bypass damper to move to divert the bypass portion to the bypass line, so the bypass portion does not contact the evaporator coil.
