Ventilation Design for Animal Rooms in Animal Laboratories: The Key to Creating a Healthy Experimental Environment
2025.03.25
In the construction of animal laboratories, the ventilation design of animal rooms is a crucial part. As Guangzhou Cleanroom Construction Co., Ltd., which specializes in the production of purification equipment, we deeply understand the great significance of a good ventilation system for the environment of animal laboratories. Today, let's take an in - depth look at the mysteries of ventilation design for animal rooms in animal laboratories.
I. Importance of Ventilation Design
1. Ensure Animal Health
During experiments, animals produce a large amount of exhaust gases, such as carbon dioxide, ammonia, and hydrogen sulfide. If these exhaust gases cannot be discharged in a timely manner, the air quality will deteriorate. Excessively high ammonia concentration can irritate the respiratory tract of animals, cause diseases, and affect the health of experimental animals and the accuracy of experimental results. Good ventilation can continuously provide fresh air, dilute harmful gases, and create a comfortable living environment for animals.
2. Protect the Safety of Experimental Personnel
There may be various pathogens in the animal room, especially when conducting research on infectious diseases. Effective ventilation can reduce the concentration of pathogens in the air and minimize the risk of experimental personnel inhaling pathogens, thus protecting their physical health.
3. Maintain the Stability of the Experimental Environment
The ventilation system helps control the temperature and humidity in the animal room. Appropriate temperature and humidity are essential for the physiological state of animals and the stability of experiments. Through ventilation, heat and moisture can be discharged, keeping the indoor temperature and humidity within an appropriate range and avoiding the impact on experimental data due to temperature and humidity issues.
II. Key Points of Ventilation Design
1. Determination of Ventilation Volume
The ventilation volume needs to be calculated comprehensively based on factors such as the area of the animal room, the type and number of animals being raised, and the intensity of experimental activities. Generally, the number of air changes per hour should be around 10 - 20 times. For example, for an ordinary animal room raising small rodents, 10 - 15 cubic meters of fresh air need to be introduced per cubic meter of space per hour. For animal rooms conducting high - risk experiments, the number of air changes may need to be increased to 20 times or more. Accurate calculation of the ventilation volume can ensure that the indoor air quality meets the standards.
2. Airflow Organization Form
A reasonable airflow organization can ensure uniform distribution of indoor air and avoid the occurrence of air - flow dead corners. The common airflow organization forms are top - supply and bottom - exhaust and top - supply and top - exhaust. The top - supply and bottom - exhaust method is more commonly used. Fresh air is supplied from the top of the room, and exhaust gases are discharged from the bottom, forming a vertical airflow direction, effectively reducing cross - contamination of exhaust gases. For some experimental areas with extremely high requirements for air quality, a unidirectional - flow ventilation system can be adopted, allowing air to flow in a single direction to further improve the air purification effect.
3. Air Purification Treatment
The air discharged from the animal room may contain pollutants such as pathogens and dust, and it needs to be purified before being discharged into the environment. The ventilation system should be equipped with appropriate air filters, such as primary filters, medium - efficiency filters, and high - efficiency filters. The primary filter can filter large - particle dust, the medium - efficiency filter can remove small - particle dust and some microorganisms, and the high - efficiency filter can filter out almost all microorganisms and fine particles. For animal rooms conducting infectious experiments, a biosafety filter also needs to be installed in the ventilation system to ensure the safety of the discharged air.
4. Selection of Ventilation Equipment
Choosing reliable ventilation equipment is the key to ensuring ventilation effectiveness. As the core equipment of the ventilation system, the fan should have sufficient air pressure and volume, and operate stably with low noise. Centrifugal fans or axial - flow fans can be selected, and a reasonable choice can be made according to actual needs and installation space. At the same time, the material of the ventilation duct is also very important. Corrosion - resistant and non - adsorbent materials, such as stainless - steel or high - quality plastic ducts, should be selected to ensure the long - term stable operation of the ventilation system.
