Abstract: Disclosed herein is an air conditioner and control method of determining duration to be maintained at a reference temperature of a mode change based on an outdoor temperature. The air conditioner includes a compressor, an outdoor heat exchanger, an indoor heat exchanger, a four-way valve configured to guide refrigerant compressed in the compressor to either the outdoor heat exchanger or the indoor heat exchanger according to a cooling mode or a heating mode, and a controller configured to determine duration corresponding to a measured outdoor temperature, change the heating mode to the cooling mode when the measured indoor temperature is maintained at a first reference indoor temperature or greater for the determined duration, and change the cooling mode to the heating mode when a measured indoor temperature is maintained at a second reference indoor temperature or less for the determined duration.

Abstract: An air conditioner, having an outdoor unit and an indoor unit, to perform a heating operation and a defrosting operation, the air conditioner including a detection unit to detect a state of at least one selected between the outdoor unit and the indoor unit and to output the detected value, a controller to determine whether the air conditioner is in a stable state when the defrosting operation is completed and, upon determining that the air conditioner is in the stable state, to control the detected value output from the detection unit to determine entry time of the next defrosting operation, and a storage unit to store a value detected in the stable state. The entry time of the defrosting operation is accurately determined, thereby minimizing the number of times of the defrosting operation during the heating operation.
