Abstract
There are disclosed a heat pump device and a drying machine using the device in which abnormal water supplying into a water-cooling heat exchanger for use in water-cooling of a heat pump can be easily detected without disposing any water amount gauge particularly. The heat pump device comprises: a water-cooling heat exchangerfor taking heat of a refrigerant which enters a capillary tubea water amount adjusting valvefor adjusting the amount of cooling water to be supplied to the water-cooling heat exchangera temperature sensororfor detecting temperature of the cooling water in the water-cooling heat exchangeror temperature of the refrigerant passed through the water-cooling heat exchanger; and a control unitfor controlling the water amount adjusting valveand the control unit judges abnormal water supplying into the water-cooling heat exchangerin accordance with the controlling state of the water amount adjusting valveand a change of the temperature detected by the temperature sensor under the controlling state.
