Description

technical field [0001] The invention relates to the technical field of air compressor cluster systems, in particular to a method and device for optimizing energy consumption of an air compressor cluster system based on big data analysis. Background technique [0002] The air compressor cluster system (air compressor cluster system) is the core system to maintain constant pressure, ventilation and cleanliness in the production environment, especially in electronic manufacturing, semiconductor manufacturing, biomedicine, chemical and other manufacturing systems that require clean rooms. . On the one hand, the air compressor cluster system must maintain a stable pressure difference between indoor and outdoor, prevent outdoor large-particle molecular pollutants from entering the production environment, and also provide many key processes and equipment that require a constant pressure environment for production use. The air compressor cluster system usually consists of multiple ...

Problems solved by technology

However, the use of nitrogen to compensate for the drop in pressure incurs additional costs and should therefore be avoided as much as possible

[0003] The compressor cluster system is usually a large power consumer in the factory, and its control method still has great defects in maintaining the optimal economy. For example: 1. Although multiple air compressors are connected in parallel to maintain the pipeline Pressure and flow requirements, but in most cases the control of each air compressor is independent of each other and will not cooperate with each other

2. Even if the air compressor cluster installed with the group control system can realize the sy...
