Abstract

A packaged terminal air conditioner unit (PTAC) and methods for operating the same are provided. The PTAC includes a vent aperture defined in a bulkhead of the PTAC and an auxiliary fan for urging a flow of make-up air through the vent aperture. A controller is configured for obtaining a room occupancy status from an occupancy system and determining a target make-up air flow rate based on the room occupancy status. The controller operates an exhaust fan, such as a bathroom fan, to urge a flow of exhaust air through an exhaust duct at an exhaust flow rate and operates the auxiliary fan to urge the flow of auxiliary air at an auxiliary flow rate, the auxiliary flow rate being substantially equivalent to the target make-up air flow rate minus the exhaust flow rate.
