Definitions

  • the present disclosure relates to an air conditioner, and more particularly, to an air conditioner having a dehumidifying function, a control method thereof, and a dehumidifying method thereof.
  • An air conditioner is a home appliance designed to condition the air in the interior space, i.e. to conduct cooling and/or heating the air in the interior space. Recently, an air conditioner having a dehumidifying function for dehumidifying the interior space has come out (see for example patent document JP-A-20020522 ). However, the dehumidifying function of the air conditioner is not enough to dehumidify the interior space and excessive power is consumed to dehumidify the interior space.
  • Embodiments provide an air conditioner, a control method thereof, and a dehumidifying method thereof that are designed to dehumidify the interior space more efficiently.
  • Embodiments also provide an air conditioner, a control method thereof, and a dehumidifying method thereof that are designed to dehumidify the interior space more economically.
  • an air conditioner includes: an air-conditioning unit exchanging heat between a cooling medium flowing therein and the air in the interior and exterior spaces so as to dehumidify the interior space; an input unit receiving a signal for selecting a mode for dehumidifying the interior space and an input dehumidifying temperature; and a control unit controlling the air-conditioning unit to continuously dehumidify, for a preset dehumidifying time, the interior space at a set dehumidifying temperature, which is set to increase by degrees depending upon the input dehumidifying temperature when the input unit receives the selection signal and the input dehumidifying temperature.
  • a control method in an air conditioner including an air-conditioning unit exchanging heat between a cooling medium flowing therein and the air of the interior and exterior spaces, an input unit receiving an operation signal for the air-conditioning unit, and a control unit controlling the air-conditioning unit according to the operation signal received by the input unit, includes: the input unit receiving a signal for selecting a dehumidifying mode and an input dehumidifying temperature; and the control unit controlling the air-conditioning unit to continuously dehumidify the interior space at a set dehumidifying temperature, which is set to increase by degrees according to the input dehumidifying temperature, for a dehumidifying time, which is set according to a value of the set dehumidifying temperature.
  • the set dehumidifying temperature increases by degrees according to the input dehumidifying temperature so as to enable the interior space to be dehumidified efficiently, providing a user with a more comfortable environment.
