Abstract
An heat pump drying machine has a normal dry mode (e.g., compression ratio is equal to or greater than 3) for operating a compressor at a predetermined dry operation frequency and an energy saving dry mode (e.g., compression ratio is equal to or greater than 2.3 and is less than 3) for operating the compressor at an energy saving operation frequency that is lower than the dry operation frequency. A control device is provided to control an operation frequency of the compressorso that the two dry operation modes are switched to each other. The control device can execute the control for increasing the operation frequency of the compressor to the dry operation frequency during the operation of the energy saving dry mode.
