An air conditioner, and a control method, including a compressor to compress a refrigerant; an outdoor heat exchanger; a first four-way valve between a discharge port of the compressor and an upper inlet of the outdoor heat exchanger; a second four-way valve between the discharge port of the compressor and a lower inlet of the outdoor heat exchanger; and a controller electrically connected to the compressor and the first four-way valve and the second four-way valve to control the first and second four-way valves to perform a first defrosting operation which defrosts an upper and a lower portion of the outdoor heat exchanger during a heating operation, and control the first and second four-way valves 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 detected need for additional defrosting of the lower portion.

Air conditioner with defrosting operation and method for controlling the same

An air conditioner and a method for controlling same are disclosed. An air conditioner according to the disclosure comprises: an indoor unit including an indoor heat exchanger and an indoor fan; an outdoor unit including a compressor; at least one sensor; at least one memory storing instructions; and at least one processor to execute the instructions to identify a freezing process to form ice-capsules on a surface of the indoor heat exchange according to a first relative humidity sensed through the at least one sensor, control the indoor fan and the compressor to operate in the identified freezing process so that the ice-capsules are formed, identify a thawing process to thaw the formed ice-capsules according to a second relative humidity sensed through the at least one sensor while the indoor fan and the compressor are operating in the identified freezing process, and control the indoor fan to operate in the identified thawing process.

Air conditioner and method for controlling same

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.
