摘要： PROBLEM TO BE SOLVED: To provide a defrosting mechanism capable of totally improving COP (coefficient of performance) including defrosting, in a heat pump device including a multi-path heat exchanger. SOLUTION: Path temperature sensors 7 respectively detect temperatures of heat exchange pipes 4a-4d as refrigerant paths in a non-contact state. A control device 150 calculates an estimated frost formation amount estimated to attach to the heat exchanger 110-1 by each of the temperatures of the heat exchange pipes 4a-4d detected by the path temperature sensors 7. The control device 150 starts the defrosting operation when any of the estimated frost formation amounts is over a prescribed threshold value, and stops the defrosting operation when all of detected refrigerant temperatures by the path temperature sensors 7 are over a prescribed temperature in executing the defrosting operation.
