An air conditioner may include an outdoor unit including a compressor and an outdoor heat exchanger configured to heat exchange compressed refrigerant; an indoor unit having an air inlet and an air outlet and connected with the outdoor unit through a first pipe through which refrigerant discharged from the compressor flows and a second pipe through which refrigerant discharged from the outdoor heat exchanger flows; a blowing fan disposed in the indoor unit; a main heat exchanger configured to heat exchange air, which flows inside through the air inlet, and connected with the second pipe; a reheat exchanger disposed downstream of the main heat exchanger and connected with the first pipe; and a waste heat exchanger disposed upstream of the main heat exchanger and configured to heat-exchange air, which flows inside through the air inlet, and condensate water, which is produced at the main heat exchanger, with each other. Accordingly, air flowing inside through the air inlet is primarily cooled before exchanging heat through the main heat exchanger, whereby the cooling and dehumidifying performance is improved.

A dehumidification system includes a primary evaporator, a primary condenser, a secondary evaporator, a secondary condenser, a superheat control evaporator, and a modulating valve. The superheat control evaporator is disposed in series with the secondary evaporator and is configured to receive an inlet airflow and output a first airflow to the secondary evaporator. The secondary evaporator receives the first airflow and outputs a second airflow to the primary evaporator. The primary evaporator receives the second airflow and outputs a third airflow to the secondary condenser. The secondary condenser receives the third airflow and outputs a fourth airflow to the primary condenser. The primary condenser outputs a dischargeable airflow. The modulating valve directs the flow of refrigerant to the secondary condenser or to the primary evaporator, depending on the mode of operation.
