The invention provides an electronic expansion valve control method and device of a water machine air conditioner and the air conditioner. The electronic expansion valve control method of the water machine air conditioner comprises the steps that the air suction superheat degree of the water machine air conditioner is obtained; the air suction superheat degree is compared with a first temperature threshold value, and a first comparison result is obtained; according to the first comparison result, whether a target control process needs to be entered is judged; and if yes, the exhaust temperature and the outlet water temperature are obtained, and the opening degree of the electronic expansion valve is controlled according to the exhaust temperature and the outlet water temperature. According to the embodiment of the invention, the electronic expansion valve can be controlled more comprehensively and accurately.

The invention provides an air conditioner and a defrosting control method and device thereof, and the defrosting control method comprises the following steps: when the air conditioner enters a defrosting mode, the operation frequency of a compressor is reduced to a first operation frequency; calculating P1 = PH1-PL1 every first phase difference time; according to the relation between a first difference value P1 after the first phase difference time and a first target difference value, the four-way valve is controlled to reverse, and a refrigerating and defrosting mode is started; the operation frequency of the compressor is reduced to second operation frequency; p2 = PH2-PL2 is calculated every second phase difference time; and according to the relation between a second difference value P2 after the second phase difference time and a second target difference value, the four-way valve is controlled to reverse, and a heating mode is started. The problems that according to the technical scheme ...
