Abstract: An air conditioner including: a housing having a discharge port and a plurality of holes; a door capable of closing the discharge port; a heat exchanger provided in the housing; a compressor connected to the heat exchanger so as to circulate a refrigerant so that same passes through the heat exchanger; a fan for blowing air so that the air passes through the heat exchanger and is discharged through the discharge port and at least one of the plurality of holes. The air conditioner includes a humidity sensor provided inside the housing so as to sense the humidity of the air having passed through the heat exchanger; and a control unit for controlling the door so as to open or close the discharge port and rotating the fan, on the basis of the humidity sensed by the humidity sensor when the compressor has been stopped.

Abstract: An air conditioner and a method for controlling the same are disclosed. The air conditioner includes a compressor; an indoor fan configured to blow an indoor air; and a controller configured to change and control a revolutions per minute (RPM) of the indoor fan to a predetermined time when the compressor is off.

Abstract: A particle sensing device and an air conditioner including a sensor has a sensing path through which air passes, a flow path housing which accommodates the sensor and guides air, and a flow path switching device to all air suctioned from the outside is guided to the sensing path, or some of the air suctioned from the outside and moving flows back in an obliquely upward direction and flows into the sensing path.

Abstract: An air conditioner includes a cabinet, a particle sensing unit coupled to the cabinet and configured to measure a particle concentration of an outside, and an inlet provided at the cabinet and configured to communicate with the outside so that particles flow into the particle sensing unit, and the particle sensing unit includes a first particle sensor configured to sense particles flowing in through the inlet, and a second particle sensor coupled to form a connection path in which particles move between the first particle sensor and the second particle sensor to sense the particles passing through the first particle sensor. The air conditioner allows the sensing of fine particles and ultrafine particles due to a plurality of particle sensors.
