Abstract:
A defrosting control method and device for a heat pump unit, a storage medium, and a heat pump unit.The method comprises: acquiring an outdoor ambient temperature and an operation state of a heat pump unit; determining whether the outdoor ambient temperature is greater than or equal to a lower limit of a first configured temperature range; and if the outdoor ambient temperature is less than the lower limit of the first configured temperature range, determining, according to the outdoor ambient temperature and the operation state, whether the heat pump unit meets a configured defrosting condition, so as to control the heat pump unit to enter a configured defrosting process when the heat pump unit meets the defrosting condition. The invention resolves the issue in which defrosting performed on fins of an outdoor unit is unreliable due to an inappropriately configured defrosting condition, thereby improving the reliability of defrosting .
