Abstract: 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.

Abstract: An air conditioner and control method for reducing power consumption by controlling pressure or temperature of a refrigerant. The air conditioner includes a compressor compressing a refrigerant and discharging a high pressure refrigerant gas; an outdoor heat exchanger in which the high pressure refrigerant gas is changed to a refrigerant fluid; an outdoor fan to blow outdoor air to the outdoor heat exchanger; a decompressor decompressing the refrigerant fluid into a low pressure state; an indoor heat exchanger changing the decompressed low pressure refrigerant fluid to a refrigerant gas; and a controller configured to control pressure or temperature of the refrigerant based on an operation condition including at least two of a first condition determined based on an installation environment, a second condition determined based on an optimal compression ratio of the compressor, a third condition determined based on outdoor temperature, and a fourth condition set as a default value.
