Requirements for laboratory ventilation engineering: good ventilation effect, low noise, simple operation, energy saving, indoor pressure difference, temperature and humidity all meet the basic needs of people. PP test bench

The importance of laboratory ventilation engineering: The laboratory ventilation engineering is one of the large-scale and influential systems in the whole process of laboratory design and construction. Whether the ventilation project is perfect or not has a direct impact on the laboratory environment, the physical health of laboratory personnel, the operation and maintenance of experimental equipment, etc.

Design principles of laboratory ventilation engineering:

1. According to the structural characteristics of the building, an air shaft shall be set nearby to divide the exhaust and air supplement systems. The pipeline system shall be "short, flat, smooth and straight" to reduce the system resistance and system noise;

2. The exhaust and make-up air systems maintain the balance of air volume, maintain the negative pressure of - 5Pa to - 10Pa indoors, prevent harmful gases from spilling, and ensure the physical and mental health of laboratory personnel;

3. Supplement cold air in summer and warm air in winter to maintain the comfort of indoor temperature and humidity;

4. Frequency conversion control system is adopted to realize the purpose of convenient operation, energy saving and noise reduction;

5. Comprehensive consideration shall be given to various factors, and mature processes with low investment, stable operation, low operation cost and good operation effect shall be adopted;

6. The selected process shall meet the site conditions, with simple and compact plane layout, less land occupation, and convenient production operation, maintenance and repair;

7. Non standard equipment shall conform to relevant industrial specifications, and maintain stable performance and beautiful appearance;

8. Noise and odor shall be considered in the design to avoid secondary pollution and new pollution to the surrounding environment;

9. The treatment facilities are capable of shock loading, so that the exhaust gas can meet the discharge standard.
