Problems solved by technology

[0003] The current ice storage projects mainly adopt a control method based on fixed logic, which is poorly adaptable to working conditions and climate changes
Regarding the performance optimization of ice storage systems, physical modeling is still the main method, and the professional threshold is high and it is difficult to promote engineering.
Compared with the traditional central air-conditioning cold source system, the system configuration of the ice storage system is more complicated, and the optimization control has greater complexity. At present, most optimization control strategies are highly coupled with field devices. Once the optimization strategy has problems , the system will run abnormally or even fail to run
