Control method and refrigerating system for fountain solution of printing machine

The invention provides a fountain solution control method for a printing machine and a refrigerating system, the method is applied to the refrigerating system, the method relates to the technical field of refrigeration, and the method comprises the steps that the temperature of the refrigerating system and parameter values of a fountain solution in the refrigerating system are obtained; according to the temperature and the parameter value, whether the current temperature of the refrigerating system and the parameter value of the fountain solution meet the printing requirement or not is judged; if the printing requirement is not met, whether the current refrigerating system meets the adjusting requirement or not is determined; and if yes, adjusting the temperature and/or the parameter value to be within a preset range. According to the scheme, the temperature of the refrigerating system and the parameter value of the fountain solution can be automatically adjusted. 本发明提供一种用于印刷机的润版液的控制方法和制冷系统，所述方法应用于制冷系统，本方法涉及制
