  • Patent number: 9518353
    Abstract: A method for controlling a drum type washing machine including a condensing duct configured to receive air from a tub, the method including supplying a first coolant into a storage unit in the condensing duct holding or maintain the first supply of the coolant in the storage unit; and supplying a second coolant into the storage unit after a preset or predetermined time period elapses is provided. The preset time period is shorter by a predetermined time length than an expected time period for thermal equilibrium between the coolant in the storage unit and the air in the condensing duct.
