Abstract
An air mover system for use in an indoor unit of a heating, ventilation, and air conditioning (HVAC) system includes a blower comprising a motor and a blower control unit configured to control operations of the motor. The blower control unit includes a controller and a sensor communicably coupled to the controller. The sensor is configured to sense air inside the indoor unit and to provide sensor information to the controller. The controller is configured to determine whether a refrigerant is present in the air based on the sensor information and to control the blower to move the air out of the indoor unit in response to determining that the refrigerant is present in the air.
