摘要： An air conditioner, and a method of controlling the air conditioner, including a compressor configured to compress a refrigerant, and including a discharge port; an outdoor heat exchanger configured to exchange heat with outside air, and including an upper portion including an upper inlet, and a lower portion including a lower inlet; a first four-way valve arranged between the discharge port of the compressor and the upper inlet; a second four-way valve arranged between the discharge port of the compressor and the lower inlet; and a controller electrically connected to the compressor, the first four-way valve and the second four-way valve. The controller may be configured to control the first four-way valve and the second four-way valve to perform a first defrosting operation which defrosts the upper portion and the lower portion during a heating operation, and control the first four-way valve and the second four-way valve to perform a second defrosting operation which operates the upper portion as an evaporator, and operates the lower portion as a condenser, based on a need for additional defrosting of the lower portion being detected.
