In the operation of animal laboratories, stable and high-quality environmental conditions are crucial to ensure the smooth progress of experiments and the accuracy and reliability of experimental results. The integrated application of fresh air systems and purification equipment in animal laboratories is like creating a precise "ecological balancer" that comprehensively and multi - level optimizes the indoor air environment. Today, Guangzhou Cleanroom Construction Co., Ltd. will take you on an in - depth exploration of this important field.

In animal laboratories, where animal breeding and experimental operations coexist, the indoor air is highly vulnerable to a variety of pollutants. Carbon dioxide exhaled by animals, ammonia emitted from excreta, dust particles, and microorganisms not only pose a threat to the health of experimental animals, interfere with their physiological functions, and thus affect the accuracy of experimental data, but also pose potential risks to the health of laboratory staff. For example, high concentrations of ammonia can irritate the respiratory tracts of both animals and humans. Long - term exposure to such an environment may lead to respiratory diseases in staff, and animals may also have their physiological states altered, affecting experimental results. Therefore, animal laboratories have extremely stringent requirements for air temperature, humidity, cleanliness, and odor.

The fresh air system plays a vital role as the "air introducer" in animal laboratories. Its main function is to introduce outdoor fresh air into the room after a series of treatments while exhausting the polluted indoor air, achieving continuous indoor - outdoor air exchange. Through reasonable design and operation, the fresh air system can accurately control the indoor temperature and humidity. In hot summer, the introduced fresh air can be cooled to bring a cool environment to the laboratory; in dry seasons, it can humidify the fresh air to maintain a suitable humidity level.

In terms of air circulation, the fresh air system ensures that indoor air flows at a scientific velocity and along a reasonable path, avoiding air stagnation areas and ensuring that every corner of the space is adequately ventilated. The air change rate is one of the important indicators for measuring the performance of the fresh air system. For animal laboratories, a relatively high air change rate is usually required, generally 10 - 20 times per hour or even higher, to quickly remove indoor pollutants and ensure air freshness.

Air filtration equipment serves as the first line of defense for purifying indoor air. The primary - efficiency filter can intercept large - particle dust, hair, and other impurities in the air; the medium - efficiency filter further filters smaller dust particles; and the high - efficiency filter can capture extremely small microorganisms, dust particles, etc., with a filtration efficiency usually reaching over 99.97% (for particles with a particle size of 0.3 microns). These filters of different grades work in tandem, layer by layer, to build a tight filtration barrier for the laboratory, keeping air pollutants out.

Odor removal equipment plays a crucial role in addressing the troublesome odor issues in animal laboratories. Malodorous gases such as ammonia generated from animal excreta not only have an unpleasant smell but also seriously affect the experimental environment. Odor removal equipment employs a variety of technical means such as activated carbon adsorption and chemical decomposition to efficiently remove these malodorous gases. For instance, activated carbon has a large specific surface area and can adsorb a large number of odor molecules; chemical decomposition technology converts malodorous gases into harmless substances through chemical reactions, effectively reducing the indoor odor concentration and creating a fresh air environment for the laboratory.

Microbial contamination is a major challenge faced by animal laboratories, making sterilization and disinfection equipment indispensable. Common sterilization and disinfection equipment includes ultraviolet germicidal lamps, hydrogen peroxide disinfectors, etc. Ultraviolet germicidal lamps achieve sterilization and disinfection by emitting ultraviolet rays that damage the DNA structure of microorganisms; hydrogen peroxide disinfectors use the strong oxidizing property of hydrogen peroxide to kill microorganisms in the air and on the surface of objects. These devices can regularly disinfect the laboratory air and environment, effectively reducing the risk of microbial contamination and ensuring the safety of experimental animals and experimental results.

The integration of the fresh air system and purification equipment enables comprehensive air purification. The fresh air system introduces fresh air, and the purification equipment filters, deodorizes, sterilizes, and disinfects the air. Working in tandem, they can significantly improve indoor air cleanliness, reduce odor concentration, and decrease the content of microorganisms, providing experimental animals with a living environment almost as fresh as nature and creating a healthy and comfortable working space for staff.

The integrated system uses intelligent control technology to automatically adjust the fresh air volume and the operating parameters of the purification equipment according to the actual needs of the laboratory. When there are fewer experimental personnel and the indoor air pollutant concentration is low, the system can appropriately reduce the fresh air volume and equipment operating power, reducing energy consumption; when the experiment is busy and more pollutants are generated, it automatically increases the fresh air volume and equipment operating intensity to ensure air quality. This intelligent operation mode achieves the goal of energy conservation and environmental protection while ensuring a good air environment.

Purification equipment will be subject to a certain degree of wear and corrosion during the process of treating air pollutants. The introduction of the fresh air system can conduct preliminary filtration and pretreatment of outdoor air in advance, reducing the amount of pollutants entering the purification equipment, thereby reducing the workload of the purification equipment and extending its service life. For example, the primary - efficiency filter in the fresh air system can first filter out most of the large - particle dust, reducing the filtration pressure on subsequent purification equipment, which extends the maintenance cycle of the entire purification equipment system and reduces equipment replacement and maintenance costs.
