Embodiment
[0031] Such as figure 1 As shown, in this embodiment, a water temperature sensor package is arranged in the middle or upper middle of the water tank for detecting the water temperature Ts.
[0032] Taking the circulating unit as an example, the working method of the heat pump water heater is as follows:
[0033] 1. When the water temperature in the water tank is 15°C, set the water temperature to 55°C; the frequency conversion heat pump water heater unit is powered on to turn on the mechanism of hot water, and the frequency is adjusted according to the normal control method.
[0034] 2. The water temperature of the water tank continues to rise. When Ts=45°C, according to the highest water temperature frequency conversion control requirements, the frequency of the frequency conversion hot water unit will not increase, and the current frequency will remain.
[0035] 3. The water temperature of the water tank continues to rise. When Ts=50°C, according to the highest water temper...
