Under the guidance of the control concept of the mature operation logic of the refrigerating station system, the operation of the central air conditioner's chillers, refrigerating pumps, cooling pumps and cooling towers is modular and energy-saving group control, which not only improves the comfort of the air conditioning environment, but also reduces the energy consumption of the air conditioning system. Establish a set of perfect remote centralized management system, through the remote monitoring system can real-time monitoring of the central air conditioning room of the running state of the equipment, timely discovery and solution of problems, while reducing human resources. The establishment of a set of energy consumption monitoring platform, through the monitoring of each electrical equipment in the freezing station, combined with the remote centralized management system, can constantly track the operating efficiency of each system and intervene in the low operating efficiency of the system, so that the system always runs in high efficiency, improve the energy utilization rate. At the same time, the energy consumption of the freezing station can be monitored in real time, refined management, production energy consumption report, some abnormal energy consumption situation can be reminded by SMS or mail, the overall COP value of the system can be monitored at all times, and the efficiency of some systems is lower than the set value can be alarm or strategic intervention. The energy consumption of the equipment room is reduced by 20%.
