the method comprises the following steps: detecting and analyzing the temperature of a water inlet and a water outlet of the ice making system, dividing the working time of the ice making system into a plurality of analysis time intervals when the ice making system works, acquiring the temperature of condensed water at the water inlet in real time in the analysis time intervals to obtain a temperature inlet coefficient and a meter inlet coefficient of the analysis time intervals, and judging whether the temperature of the condensed water at the water inlet meets the requirement or not according to the numerical values of the temperature inlet coefficient and the meter inlet coefficient; judging whether the heat exchange efficiency meets the requirement or not when the temperature of the condensed water at the water inlet meets the requirement; step two is executed when the heat exchange efficiency does not meet the requirement; step three is executed when the heat exchange efficiency meets the requirement;
step two: detecting and analyzing the running state of the ice making equipment to obtain a running coefficient of the ice making equipment, and judging the reason that the heat exchange efficiency does not meet the requirement as equipment failure or heat exchanger failure according to the numerical value of the running coefficient;
step three: and performing predictive analysis on the heat exchange efficiency of the ice making system, marking the analysis time period as a normal time period or an early warning time period, judging that the predictive analysis result is unqualified when L1 early warning time periods continuously appear, and executing the step two.
