With the development of science and technology, China's semiconductor, microelectronics, biopharmaceuticals and other high-tech industries have developed rapidly, and the dust-free workshop as an important infrastructure of these industries, its internal purification and air-conditioning system is of great significance to ensure product quality and production environment. However, while the purification air conditioning system provides a high-quality environment for the clean room, it also has the problem of high energy consumption. How to reduce the energy consumption of the purified air-conditioning system and achieve energy conservation and emission reduction under the premise of ensuring the environmental requirements of the dust-free workshop has become a hot issue of concern for enterprises.
1. Rational design of purification and air-conditioning system
1. Reasonable classification of air quality grades: According to the production process requirements of the dust-free workshop, the air quality grades should be reasonably divided to avoid excessive purification to reduce energy consumption. For example, in areas where high-level decontamination requirements are not required in the production process, the decontamination level can be appropriately reduced.
2. Optimize the layout of the air-conditioning system: reasonably arrange the air supply outlet, return air outlet, fresh air outlet, etc., so that the air flow path is the shortest and the energy consumption is reduced. At the same time, the air conditioning system is avoided from spanning too large a space, reducing the air delivery distance.
3. Adopt the appropriate air supply mode: According to the specific needs of the dust-free workshop, choose the appropriate air supply mode, such as top air supply, bottom air supply, side air supply, etc. Reasonable selection of air supply mode can improve the uniformity of air distribution and reduce energy consumption.
4. Set the filter reasonably: choose the type and level of the filter reasonably, not only to ensure air quality, but also to reduce energy consumption. The choice of filter should be determined based on the requirements of the production process and the air quality rating.
Second, the selection of high-efficiency and energy-saving equipment
1. High-efficiency and energy-saving air-conditioning units: Choose high-efficiency and energy-saving air-conditioning units, such as inverter-speed air-conditioning units, heat pump air-conditioning units, etc. These units have a high energy efficiency ratio, which can effectively reduce energy consumption.
2. High-efficiency and energy-saving fans: choose high-efficiency and energy-saving fans, such as inverter fans, energy-saving axial fans, etc. Energy-efficient fans can reduce energy consumption while meeting air volume requirements.
3. High-efficiency and energy-saving filters: Choose high-efficiency and energy-saving filters, such as low-resistance filters, electrostatic filters, etc. Energy-efficient filters can reduce energy consumption without sacrificing air quality.
3. Optimize operation management
1. Reasonable adjustment of operating parameters: According to the actual needs of the dust-free workshop, reasonably adjust the operating parameters of the air-conditioning system, such as temperature, humidity, air volume, etc. Avoid over-cooling, heating, and humidification to reduce energy consumption.
2. Regular maintenance: Regularly maintain the purification and air-conditioning system to ensure that the system runs stably and the equipment efficiency is optimal. At the same time, replace damaged parts in time to avoid increased energy consumption.
3. Reasonable arrangement of production plan: Reasonable arrangement of production plan to avoid overlap between the peak period of production and the peak period of operation of the air conditioning system, so as to reduce energy consumption.
Fourth, the use of advanced energy-saving technology
1. Inverter technology: Inverter technology is used to control the motor of the air-conditioning system to adjust the motor speed according to the actual demand, so as to achieve energy saving.
2. Heat recovery technology: Heat recovery technology is used to recycle the heat generated by the air conditioning system, such as using waste heat for humidification and heating, so as to reduce energy consumption.
3. Waste heat utilization technology: The waste heat generated in the production process, such as waste heat in semiconductor production, is used to heat or cool the air conditioning system to achieve energy saving.
4. Intelligent control system: The intelligent control system is used to monitor and optimize the operation of the air conditioning system in real time to achieve energy saving.
In short, the key to energy saving of purification and air-conditioning system in dust-free workshop lies in reasonable design, selection of high-efficiency and energy-saving equipment, optimization of operation management and adoption of advanced energy-saving technology. Through these measures, the energy consumption of the purified air-conditioning system can be reduced and energy conservation and emission reduction can be achieved under the premise of ensuring the environmental requirements of the dust-free workshop.
