  • Systems and methods for blower control in an HVAC system
    Patent number: 12613052
    Abstract: A method of conditioning air within an enclosed space using an HVAC system includes controlling, by a controller, the HVAC system to cool the air within an enclosed space in response to a command from a thermostat that monitors a temperature in the enclosed space. The controller receives a humidity reading from the humidity sensor and determines whether to operate at improved cooling efficiency or at improved dehumidification efficiency based at least in part on the humidity reading. The controller determines an operating speed for the blower to achieve the determined operation at improved cooling efficiency or operation at improved dehumidification efficiency and continues to control the HVAC system to condition the air within the enclosed space including operating the blower at the determined operating speed.
