US Patent 11281201 Air conditioner and methods of operation having a learning event

An air conditioner, as provided herein, may include a cabinet, an outdoor heat exchanger, an indoor heat exchanger, a compressor, an internal temperature sensor, and a controller. The controller may be configured to initiate a conditioning operation. The conditioning operation may include detecting a learning condition at the air conditioner, identifying a first operating mode, and initiating a learning event at the first operating mode. The conditioning operation may further include measuring performance during the learning event, recording a baseline variable based on the measured performance during the learning event, and measuring performance at the first operating mode. The conditioning operation may still further include recording an operational variable based on the measured performance at the first operating mode, comparing the operational variable of the first operating mode to the baseline variable of the first operating mode, determining a fault state based on the comparison, and recording the fault state.
