Abstract (en)
The present invention discloses a heat pump type water heater system including a refrigerant circuit having a water/refrigerant heat exchanger for condensing a refrigerant to release heat from the refrigerant to water passing through the water/refrigerant heat exchanger; a water tank that stores water capable of passing through the water/refrigerant heat exchanger to obtain heat from the refrigerant when the refrigerant circuit is working; and a cold water reservoir that stores cold water capable of passing through the water/refrigerant heat exchanger when the refrigerant circuit is not working. In this way, cold water from the cold water reservoir in addition to the water tank passes through the water/refrigerant heat exchanger when the refrigerant circuit is not working to avoid formation of scales and/or remove scales existing in the water/refrigerant heat exchanger.
