In the construction and operation of large factory buildings, the design of ventilation systems is one of the key elements to ensure production environment safety, employee comfort, and normal equipment operation. A reasonable and efficient ventilation system can not only provide fresh air, but also help maintain a stable temperature and humidity environment, reduce indoor air pollution, and improve production efficiency.
1、 Air quality standards and requirements
Indoor air quality standards: In the design of ventilation systems in large factory buildings, relevant indoor air quality standards must be met. According to relevant regulations, set reasonable indoor air quality indicators, including CO2 concentration, PM2.5 concentration, temperature, humidity, etc., to ensure that employees can breathe fresh air during work.
Applicable scenario analysis: The design of ventilation systems needs to fully consider the special processes and production processes of large factories, as well as the different air quality requirements of different regions. For example, production workshops may require higher ventilation, while office areas may place greater emphasis on quietness.
2、 Ventilation system layout and design
Regional division and ventilation control: Reasonable regional division is the foundation of ventilation system design. The ventilation requirements vary in different functional areas, and reasonable design should be carried out to ensure that each area has an appropriate amount of fresh air and avoid cross contamination.
Design of air vents and wind speeds: The design and layout of air vents need to consider the uniformity of air circulation, avoiding dead corners and areas with insufficient ventilation. At the same time, it is necessary to control the wind speed reasonably to ensure the ventilation effect without causing discomfort.
The selection and configuration of ventilation equipment: The selection of ventilation system equipment is crucial. Select appropriate types and quantities of ventilation equipment based on the area, height, and process requirements of large factory buildings to ensure stable performance and high energy efficiency.
3、 Environmental monitoring and regulation
Real time monitoring system: Install a real-time monitoring system to monitor indoor temperature, humidity, gas concentration, and other parameters in real time through sensors, detect abnormal situations in a timely manner, and make adjustments.
Intelligent regulation technology: Introducing intelligent regulation technology, the intelligent operation of the ventilation system is achieved through an automatic control system, and the ventilation volume is adjusted according to different time periods and working conditions to improve the energy efficiency of the system.
4、 Safety and emergency response
Fire and explosion prevention design: In the design of ventilation systems for large factory buildings, fire and explosion prevention requirements should be fully considered, and flame retardant materials and equipment should be used to ensure the safety of the ventilation system in emergency situations.
Emergency ventilation plan: Develop a comprehensive emergency ventilation plan, including emergency ventilation measures in case of sudden fire, toxic gas leakage, etc., to ensure the safe evacuation of employees.
5、 Energy consumption control and optimization
Energy saving equipment and technology: In the design of ventilation systems, priority should be given to selecting equipment with higher energy efficiency, combined with energy-saving technologies such as frequency conversion control and energy recovery, to reduce the energy consumption of system operation.
Regular maintenance and cleaning: Establish a regular maintenance and cleaning mechanism to maintain the good condition of ventilation equipment and avoid increased energy consumption caused by equipment aging or blockage.
6、 Humanized design and comfort enhancement
Noise control: In the design of ventilation systems, noise control measures should be taken to ensure that the noise level during the operation of the ventilation system is within an acceptable range.
Air circulation design: Through a reasonable ventilation system design, the air can circulate to every corner, ensuring the uniformity of indoor air and improving the work comfort of employees.
In the design of ventilation systems in large factory buildings, a standardized and reasonable design scheme is directly related to the quality of the production environment and the health of employees. By following relevant design specifications, introducing intelligent technology, and focusing on energy conservation measures, the efficient, stable, and safe operation of ventilation systems in large factories can be achieved, providing strong support for the sustainable development of enterprises. In the future, with the continuous advancement of technology, ventilation system design will become more intelligent and green, creating a more pleasant production environment for large factories.
