Abstract: An example air conditioner may include a compressor configured to compress a refrigerant; an indoor heat exchanger configured to perform heat exchange between the refrigerant and indoor air; a temperature sensor configured to measure an indoor temperature and an indoor heat exchanger temperature; an input device configured to receive a target temperature and target humidity from a user; and at least one processor configured to determine an adjustment value of an operating frequency of the compressor based on a temperature difference between the target temperature and the indoor temperature, and change the determined adjustment value of the operating frequency based on the target humidity and the indoor heat exchanger temperature.

Abstract: An air conditioner may include: a compressor; a flow path switching valve; a first flow path connecting an outlet of the compressor to the flow path switching valve; a first heat exchanger; a second flow path connecting the first heat exchanger to the flow path switching valve; a first refrigerant port fluidly connected to an indoor unit; a third flow path extending from the first heat exchanger to the first refrigerant port; a sub-cooler provided on the third flow path; a first expansion valve provided between the first heat exchanger and the sub-cooler on the third flow path; a second expansion valve provided between the sub-cooler and the first refrigerant port on the third flow path; a fourth flow path branched from a branch point of the third flow path, passing through the sub-cooler, and extending to an inlet of the compressor; a third expansion valve provided between the sub-cooler and the branch point on the fourth flow path; a second refrigerant port fluidly connected to the indoor unit; a fifth flow path connecting the second refrigerant port to the flow path switching valve; and a sixth flow path connecting the flow path switching valve to an intake port of the compressor.

Abstract: An air conditioner and a control method thereof. The air conditioner includes an indoor unit including an indoor heat exchanger and an indoor fan, an outdoor unit connected to the indoor unit and including an outdoor heat exchanger, an outdoor fan, a compressor, an expansion valve, and a four-way valve, and at least one processor configured to perform a test operation by controlling the indoor unit and the outdoor unit. Based on an outdoor temperature being less than a predetermined reference temperature, the at least one processor is configured to determine whether the indoor unit and the outdoor unit operate normally, by continuously performing a heating operation and a defrosting operation during the test operation.
