摘要：
A heat-pump device indicates a weight of inappropriate amount of refrigerant in a heat-pump cycle by comparing an actual amount of refrigerant in the heat-pump cycle with an appropriate amount thereof, operates in accordance with a refrigerant amount judging operational mode when the actual amount of refrigerant is measured, and includes a judging device for judging the amount of refrigerant in the heat-pump cycle on the basis of a temperature of refrigerant at a condensor side and at least one information showing an operational condition of the heat-pump cycle.
