Embodiment 1
[0051] In this example, if figure 1 As shown, a heat pump water heater secondary heating control method, the heat pump water heater includes a detector for detecting the water temperature of the water tank and the ambient temperature, including the following steps:
[0052] Obtain the temperature parameters of the heat pump water heater;
[0053] Calculate and compare the set temperature hysteresis T and the actual temperature hysteresis t according to the temperature parameters of the heat pump water heater;
[0054] The secondary heating of the heat pump water heater is controlled according to the comparison result.
[0055] This embodiment provides a heating control method for the heat pump water heater with simple logic, which can effectively reduce the start-up frequency of the compressor and prolong the service life of the heat pump water heater under the condition of ensuring the supply water temperature.
[0056] In this embodiment, the temperature parameters include t...
