Shenyang Ventilation Engineering Tell you: Lab Ventilation engineering Design principles of

Importance of laboratory ventilation engineering: laboratory ventilation engineering is one of the systems with large scale and wide influence in the whole process of laboratory design and construction. Whether the ventilation project is perfect or not will directly have an important impact on the laboratory environment, the health of laboratory personnel, the operation and maintenance of laboratory equipment, etc.

Requirements of laboratory ventilation engineering: good ventilation effect, low noise, simple operation, energy saving, indoor pressure difference, temperature and humidity can maintain human comfort.

Design principles of laboratory ventilation engineering:

1. The treatment facilities have impact load capacity to ensure that the exhaust gas is discharged up to the standard.

2. Supplement cold air in summer and warm air in winter to ensure the comfort of indoor temperature and humidity.

3. Intelligent frequency conversion control system is adopted to achieve the purpose of convenient operation, energy saving and noise reduction.

4. Non standard equipment shall comply with relevant national or industrial specifications, and ensure stable performance and beautiful appearance.

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. In the design, full consideration shall be given to noise, odor, etc. to prevent secondary pollution and new pollution to the surrounding environment.

7. The selected process must meet the site conditions, the plane layout is simple, compact, occupies less land, and is convenient for production, operation, maintenance and repair.

8. The exhaust and makeup air systems shall achieve the air volume balance, maintain the negative pressure of - 5Pa - 10Pa indoors, prevent the diffusion and overflow of harmful gases, and ensure the physical and mental health of laboratory personnel.

9. According to the structural characteristics of the building, set up an air shaft nearby, divide the air exhaust and air supplement systems, and make the pipeline system "short, flat, smooth and straight" to reduce the system resistance and system noise.
