Embodiment 1
[0034] In this embodiment, the water temperature control method of the variable frequency heat pump water heater of the present invention is described in detail.
[0035] The water temperature control method of the variable frequency heat pump water heater in this embodiment includes the following steps:
[0036] S1: Obtain the real-time water temperature of the water tank 102 . Specifically, the real-time water temperature of the water tank 102 can be acquired through the temperature sensing package 107 disposed on the water tank 102 .
[0037] S2: Compare the real-time water temperature of the water tank 102 with the preset water temperature of the water tank 102 .
[0038] S3: when the difference between the real-time water temperature of the water tank 102 and the preset water temperature of the water tank 102 is outside the preset difference range, adjust the compressor frequency of the variable frequency air-energy heat pump water heater unit 101 and / or the opening of the...
Embodiment 2
[0076] In this embodiment, the water temperature control device of the variable frequency heat pump water heater of the present invention is described in detail.
[0077] The water temperature control device of the variable frequency heat pump water heater in this embodiment includes: an acquisition module 201, a comparison module 202 and an adjustment module 203, such as figure 2 shown. Preferably, the acquisition module 201 is used to acquire the real-time water temperature of the water tank 102; the comparison module 202 is used to compare the real-time water temperature of the water tank 102 with the preset water temperature of the water tank 102; When the difference between the two is outside the preset difference range, adjust the compressor frequency of the variable frequency air-energy heat pump hot water unit 101 and / or the opening of the electronic warm water valve 104, and make the real-time water temperature of the water tank 102 and the preset water temperature o...
