Abstract:

In this study, a systematic energy efficiency classification and dynamic management and control strategy were constructed for the water cooler of the refining and chemical unit. Through in-depth analysis of the working principle of the water cooler and the influencing factors of energy efficiency, a comprehensive energy efficiency detection, calculation, and grading evaluation system was established, laying the foundation for scientific classification management. For different energy efficiency levels, a series of dynamic management and control strategies were proposed, covering operating parameter optimization and equipment structure improvement to achieve real-time improvement of energy efficiency. Practice has shown that this strategy significantly improves the energy efficiency of water coolers, reduces energy consumption and environmental pollution. This achievement provides a practical guide for refining and chemical companies to improve the energy efficiency of water coolers, lays a foundation for research in related fields, helps to promote the transformation of the refining industry towards high efficiency and environmental protection, and reflects the important value of scientific energy efficiency evaluation and flexible control strategies.

Key words: refining and chemical unit, water cooler, energy efficiency classification, dynamic management and control, energy efficiency detection, energy efficiency calculation, energy efficiency evaluation
