Laboratory Ventilation System Planning and Design Elements
Laboratory Ventilation System Planning and Design Core Elements
1. Safety Assurance
Safety is the primary principle in ventilation system design, centered around precisely controlling airflow for various laboratory equipment. For critical equipment such as fume hoods and biological safety cabinets, ensure that toxic and hazardous gases generated during experiments are completely captured, eliminating the risk of spills and safeguarding the health of operators. Furthermore, maintaining a negative pressure in the laboratory safeguards the surrounding environment.
2. Precise Pressure Control
Laboratories such as those involved in biochemistry require strict maintenance of negative pressure indoors. This design creates an effective air barrier, preventing the spread of toxic gases generated in the experimental area to surrounding areas and thus preventing cross-contamination.
3. Maintainability
System design should be simple and reliable, avoiding overly complex structures and offering ease of maintenance to reduce long-term operational challenges.
4. Energy Efficiency
Unlike ordinary buildings, laboratories typically require 100% fresh air and continuous operation. Therefore, optimized design is crucial to minimize energy consumption and operating costs. 5. Temperature and Humidity Comfort
The ventilation system must coordinately regulate the laboratory's temperature and humidity, ensuring they remain within an appropriate and stable range while also ensuring stable airflow and a lack of odor.
6. Scalability
Fully consider the laboratory's future development needs during the design phase, reserving space for subsequent renovations and expansions. This allows for the replacement, relocation, and expansion of laboratory equipment, as well as adjustments to laboratory pressure.
Laboratory Ventilation System Design Nine Principles
1. Adaptation to the Building Structure: Rationally divide the exhaust and supply air systems. Pipeline layout should adhere to the principles of "short, flat, smooth, and straight" to reduce system resistance and minimize noise generated during airflow.
2. Balancing Air Volume and Negative Pressure: Ensure that the air volume of the exhaust and supply air systems is balanced, maintaining a negative pressure environment indoors and preventing the release of harmful gases at the source.
3. Temperature and Humidity Control: Targeted supply air adjustments are implemented based on seasonal changes.
4. Intelligent Energy Saving and Noise Reduction: Utilize an intelligent variable frequency control system to automatically adjust air volume and dynamically adjust energy consumption based on actual needs, thereby reducing noise.
5. Balance economic efficiency and practicality: Comprehensively consider multiple factors, including initial investment, operational stability, daily operating costs, and user experience.
6. Optimize floor plan: Strive for a simple and compact layout to minimize floor space while facilitating experimental operations, equipment maintenance, and repair.
7. Standardize non-standard equipment: For non-standard equipment, the design and manufacturing must strictly adhere to national or industry standards to ensure stable and reliable performance.
8. Prevent secondary pollution: Fully consider potential pollution issues such as noise and odor during the design process to prevent secondary pollution.
9. Resilience to load fluctuations: Exhaust gas treatment facilities must be able to withstand shock loads, ensuring stable operation and standard exhaust emissions even when experimental loads fluctuate.
