Electronic expansion valve control method and device of water machine air conditioner and air conditioner

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. 本发明提供了一种水机空调器的电子膨胀阀控制方法、装置和空调器，水机空调器的电子膨胀阀控制方法包括：获取水机空调器的吸气过热度；将吸气过热度与第一温度阈值进行比较，获得第一比较结果；根据第一比较结果，判断
