転装置。The maximum temperature difference between the inlet fluid temperature and outlet fluid temperature of the heat exchanger on the user side of the heat pump during one cycle from the start of heating operation to the start of defrosting operation is stored, and the temperature difference is the stored maximum temperature difference. In a heat pump defrosting operation device that starts defrosting when the temperature drops below a set value, the difference between the inlet fluid temperature when the maximum temperature difference is detected and the inlet fluid temperature that changes as the heating operation progresses A defrosting operation device for a heat pump, characterized in that the set value is corrected based on the temperature difference, and the defrosting operation is switched to when the temperature difference between the inlet fluid temperature and the outlet fluid temperature becomes equal to or less than the corrected set value.
