Cooling-water machine control method and device and cooling-water machine

The embodiment of the invention provides a control method and device of a water chiller, the water chiller, electronic equipment and a computer readable storage medium, the method is suitable for the water chiller with a plurality of detection points in a water storage tank, and the method comprises the steps that after the water chiller starts refrigeration, a first temperature value of any detection point is obtained in real time; when the first temperature value is smaller than a preset temperature value, a second temperature value is obtained, and the second temperature value is the temperature value of a detection point adjacent to or spaced from the detection point corresponding to the first temperature value; and controlling the cooling-water machine to stop refrigerating according to the numerical value of the second temperature value. The multiple detection points can be arranged in the water storage tank, the temperature values of the multiple detection points are obtained at the same time, comprehe
