Abstract: Disclosed is a dryer operating method that is useful in a 5G environment provided for the Internet of Things. The dryer of the disclosure includes a heating device, a tumbler connected to the exit of the heating device, a fan connected to the exit of the tumbler, a heat exchanger disposed in a flow line of a working fluid connected to the exit of the fan, and a compressor having an entrance connected to the flow line connected to the exit of the fan and an exit connected to the entrance of the heat exchanger. The method of the disclosure includes heating the working fluid using the heating device, reducing the pressure in the tumbler by discharging a portion of the working fluid in a circulation line to outside using the compressor, drying an object to be dried received in the tumbler, and cooling the object to be dried.
