Heat pump system and defrosting control method
By dividing the heat exchanger of the heat pump system into two sections and dynamically adjusting the refrigerant circuit according to the ambient temperature and inlet water temperature, the problem of low defrosting efficiency in existing heat pump systems is solved, achieving a more efficient defrosting effect and improved system performance.
