Requirements And Importance Of Laboratory Ventilation Engineering

The requirements for laboratory ventilation engineering are: good ventilation effect, low noise, easy operation, energy saving, and indoor pressure difference and temperature and humidity that meet the basic needs of people.
The importance of laboratory ventilation engineering: Laboratory ventilation engineering is one of the large-scale and widely influential systems in the entire laboratory design and construction process. The completeness of ventilation engineering directly affects the laboratory environment, the physical health of laboratory personnel, and the operation and maintenance of experimental equipment.
Design principles for laboratory ventilation engineering:
1. According to the structural characteristics of the building, nearby air shafts should be set up, and exhaust and makeup air systems should be divided. The pipeline system should be "short, flat, smooth, and straight" to reduce system resistance and noise;
2. The exhaust and makeup air systems maintain a balance of air volume, maintain a negative pressure of -5Pa to -10Pa indoors, prevent harmful gases from escaping, and ensure the physical and mental health of experimental personnel;
3. Supplement cold air in summer and warm air in winter to maintain the comfort of indoor temperature and humidity;
4. Adopting a frequency conversion control system to achieve the goals of easy operation, energy saving, and noise reduction;
5. Taking into account various factors, mature processes with low investment, stable operation, low operating costs, and good operating effects are adopted;
6. The selected process should meet the on-site conditions, with a simple and compact layout, minimal land occupation, and convenient production operation and maintenance;
7. Non standard equipment should comply with relevant industry standards, maintain stable performance, and have a beautiful appearance;
8. Consider noise, odors, etc. in the design to avoid secondary pollution and prevent new pollution to the surrounding environment;
9. The treatment facilities have the ability to withstand impact loads and ensure that exhaust gases meet emission standards.
