[Abstract]:TFT-LCD plant has the characteristics of high investment, large building volume and large energy consumption. In order to achieve energy saving and consumption reduction in the stage of plant design, construction and operation, scientific, reasonable and feasible energy saving measures and energy saving projects should be taken in view of key energy consumption processes, energy consumption equipment and key factors affecting energy consumption. In order to achieve a better energy-saving effect. In this paper, the types of energy consumption, the structure of energy consumption and the characteristics of energy distribution, the energy balance in the process of main energy processing and conversion, and the energy efficiency index in TFT-LCD plant are studied and analyzed. This paper summarizes the experience data of the similar projects completed in our hospital for many years, and deeply analyzes the main energy use systems and the characteristics of energy use through the analytic hierarchy process, the energy balance analysis method, the standard contrast method and so on. The results show that electric power is the largest energy consumption in TFT-LCD project, which accounts for more than 75% of the total energy consumption of the whole plant. The electric power consumption of process production equipment accounts for 45% of the total power consumption in the whole plant, and the array is the most important process of process energy consumption. Power equipment such as chillers is the main energy consuming equipment in the plant management system, and nitrogen is the most consumed working medium, accounting for about 20% of the total energy consumption of the plant. The energy consumption structure and energy use characteristics basically accord with the actual operation characteristics of this kind of factory, which has a high guiding value for the energy saving of TFT-LCD panel project.
