摘要： A dehumidifying apparatus of an air conditioner and a control method thereof by which a heating/dehumidifying operation is performed when a room temperature is lowered. When the room temperature reaches a predetermined temperature, the air conditioner is switched to a cooling operation to perform a heating/dehumidifying operation, so that heating and cooling operations are inter-switched according to changes of room temperature to keep the room temperature from dropping and to improve dehumidifying efficiency according to increased temperature of the indoor heat exchanger, the apparatus comprising: a four-way valve for changing flow of coolant to thereby transform a cooling cycle to a heating cycle; room temperature detecting unit for detecting a room temperature; outdoor temperature detecting unit for detecting an outdoor temperature; and a control unit for controlling drive of the four-way valve according to the room temperature detected by the room temperature detecting unit when the outdoor temperature detected by the outdoor temperature detecting unit is above a predetermined temperature to thereby switch to cooling/heating and to controllably drive the compressor, the outdoor fan and the indoor fan according to the cooling/heating switch.
