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.

Abstract: The humidifier includes a humidifying member, a storage water tank, a circulating water tank, a residual water tank, a supply pump configured to supply water accommodated in the storage water tank to the circulating water tank, a circulating pump configured to supply water accommodated in the circulating water tank to the humidifying member. A fan configured to blow air toward the humidifying member and thereby cause water evaporated to be discharged outside the humidifier, an internal pipe configured to form a flow passage through which water not evaporated by the humidifying member is recovered to the circulating water tank, a drainage member configured to selectively discharge water accommodated in the circulating water tank to the residual water tank, and a controller configured to operate the humidifier in humidity mode based on the water level in the storage water tank.

Abstract: A humidifier includes a storage water tank configured to accommodate a predetermined amount of water; a circulation water tank having a smaller capacity than the storage water tank and including a circulation low water level sensor; a supply pump configured to supply water from the storage water tank to the circulation water tank; a circulation pump configured to supply water from the circulation water tank to a humidifying member; a residual water tank configured to accommodate water discharged from the circulation water tank; a drainage member disposed between the circulation water tank and the residual water tank selectively to discharge water from the circulation water tank to the residual water tank and a processor configured to control the drainage member to discharge water from the circulation water tank to the residual water tank when a low water level signal is received from the circulation low water level sensor.
