Referring to fig. 1, in this embodiment, a heat pump water heater includes a heat pump host 1, a main heat storage water tank 2 and a buffer water tank 3, in which, the heat pump host 1 respectively extends to the main heat storage water tank 2 and the buffer water tank 3 in a circulating manner through two sets of heat exchange pipelines arranged in parallel, so that the heat pump host 1 conveys high-temperature and high-pressure refrigerants to the main heat storage water tank 2 and the buffer water tank 3 for heat exchange through the two sets of heat exchange pipelines. The heat pump main unit 11 of the embodiment mainly includes a compressor, an outdoor evaporator, a throttle unit, a fan, and other conventional components.
In this embodiment, the buffer tank 3 is communicated with the main hot water storage tank 2 through the branch pipe 4, and the branch pipe 4 is provided with the auxiliary solenoid valve 41, so that the communication between the buffer tank 3 and the main hot water storage tank 2 is controlled by controlling the on-off operation of the auxiliary solenoid valve 41, and the stored water in the buffer tank 3 is transferred to the main hot water storage tank 2 through the branch pipe 4. An electric heating unit 32 is arranged in the buffer water tank 3, and the water in the buffer water tank 3 can be subjected to auxiliary electric heating through the electric heating unit 32.
In the present embodiment, a water temperature sensing probe for monitoring the water temperature in real time is provided in the main hot water storage tank 2 and the buffer tank 3.
From this, during normal preheating, heat pump host 1 heats main hot water storage tank 2 and buffer tank 3 respectively through two heat transfer pipelines and heaies up, monitors the temperature in real time through temperature sensing probe, and when the temperature of main hot water storage tank 2 and buffer tank 3 reached predetermined target temperature, heat pump host 1 closed and stops heating work. The sub solenoid valve 41 is in a closed state at this time.
