Kind Code:
A1
Abstract:
An air conditioner according to an embodiment of the present disclosure comprises: an inverter for driving a first motor and a second motor connected in parallel with each other; and a processor for determining a parameter of the first motor and a parameter of the second motor, determining whether there is a difference in a predetermined value or more by comparing the determined parameter of the first motor with the determined parameter of the second motor, and controlling the inverter through a heterogeneous control of the first motor and the second motor when the determined parameter of the first motor and the parameter of the second motor differ from each other by a predetermined value or more in the result of the determination.
