The application discloses a cement raw material mill equipment production scheduling optimization method, and steps include: using the historical mill time and power data of the raw material mill in the database, the working conditions of the raw material mill are divided into three kinds of working conditions through the clustering analysis method, and the maximum and minimum values of the corresponding mill time are found out from each kind of working condition; the first linear programming is used to plan the running time of the raw material mill; if the result shows that the ending time point of the current time and the starting time point of the next time interval are not more than the set value, the production scheduling task of the next time interval is migrated to the current time interval; the second linear programming is used to plan and arrange the mill time in the running time interval; the starting and ending time points of each time interval running time interval and the running mill time of each time interval are obtained; and the application can maximize the economic benefits of enterprises, limit the frequency of starting and stopping machines and reduce the equipment wear under the premise of meeting the total output.

This utility model discloses a thermal management system suitable for containerized energy storage systems, comprising an air conditioning refrigerant circuit and a battery thermal management circuit, both of which include plate heat exchangers. Through this structure, the integration of the air conditioning refrigerant circuit and the battery thermal management circuit reduces system complexity and cost, while also reducing space requirements and maintenance costs. The battery thermal management system utilizes the plate heat exchanger to form a heat exchange with the air conditioning refrigerant circuit, effectively dissipating the heat absorbed from the energy storage battery module through the air conditioning system. The air conditioning refrigerant circuit dynamically adjusts the refrigerant distribution to regulate the heat exchange distribution between the air conditioning refrigerant circuit and the battery thermal management circuit. The battery thermal management circuit includes a phase change thermal storage unit connected in parallel with the plate heat exchanger, releasing stored heat / cold energy during charging and discharging intervals, reducing the frequent start-stop of the compressor and PTC heater.
