The biological advantages of central air conditioning KBS system are as follows:
In terms of system function, the traditional computer room equipment electric control cabinet+computer room equipment frequency conversion energy-saving system+computer room building control system is integrated, which greatly simplifies the design and implementation of computer room power distribution, weak current monitoring and energy saving. The interface between subsystems does not need to agree and cooperate, which will consume a lot of precious time. From the hardware composition, it consists of fuzzy control cabinet, refrigeration (temperature) pump control cabinet, cooling pump control cabinet, fan control cabinet and various field control cabinets. Fuzzy control cabinet is the control core of the whole system, which is responsible for the realization of man-machine interface, system-level control and energy-saving control algorithm. Each pump control cabinet is an electrical and control integrated device, which is responsible for the variable speed drive of the corresponding pump motor and the control of the corresponding valves. The built-in intelligent controller can be controlled independently, making the system more reliable. The field control box mainly completes the access of field sensor signals.
The original fuzzy prediction algorithm is used to adjust the cold (warm) water system, so that the delivery flow of cold (warm) water can be adjusted closely with the change of air conditioning load, which overcomes the problem that the control system is difficult to adjust stably during debugging.
The original fuzzy optimization algorithm is used to adjust the cooling water system, dynamically find the cooling water flow corresponding to the optimal efficiency of the system and automatically complete the adjustment, so that the comprehensive operation power consumption of the cooling system and the air conditioning host is always in the most economical state.
The unit group control strategy is adopted to track the load change and optimize the efficiency of the main engine, and the combination of the main engine and the number of operating units are intelligently selected to ensure the efficient operation of the system. Focus on improving energy efficiency.
The hydraulic dynamic regulation function based on energy balance makes the transportation and distribution of frozen (warm) water more reasonable and controllable, and can further reduce the energy consumption of transporting frozen (warm) water.
The software has various functions: each device can be flexibly configured, forming different control logics, and arbitrarily selecting associated control mode, time program control mode and optimal efficiency control mode; Various real-time process parameters and equipment status can be seen at a glance; Rich process parameters, energy consumption data, event alarm records and curves, let you know the running state of the controlled air conditioning system; Service quality control function, equipment maintenance and management function, energy consumption measurement function and SMS prompt function make management worry-free and labor-saving.
