Patent number: 11927358Abstract: The present disclosure relates to a heating, ventilating, and air conditioning (HVAC) unit configured to supply conditioned air to a conditioned space. The HVAC unit includes a first exhaust fan capable of operating at variable speeds and a second constant-speed fan. The HVAC unit also includes a controller configured to determine a target airflow to be provided to the conditioned space, cause actuation of the first exhaust fan at a variable fan speed when the target airflow is greater than zero, and cause actuation of the second exhaust fan when the target airflow is greater than an airflow threshold.Type: GrantFiled: October 11, 2021Date of Patent: March 12, 2024Assignee: JOHNSON CONTROLS TYCO IP HOLDINGS LLPInventors: Gaurav S.
