Abstract: An air conditioner is provided. The air conditioner includes an indoor unit including an expansion valve and an indoor heat exchanger, a compressor configured to supply a refrigerant to the indoor unit, a compressor inlet pressure sensor configured to detect a compressor inlet pressure corresponding to a pressure of the refrigerant flowing into the compressor from an accumulator, memory storing one or more computer programs, and one or more processors communicatively coupled to the compressor inlet pressure sensor and the memory, wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the air conditioner to adjust an opening degree of the expansion valve of the indoor unit based on the compressor inlet pressure during a defrosting operation.

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.
