In the construction of animal laboratories, the scale of the laboratory is one of the key factors determining the selection of purification equipment. As Guangzhou Cleanroom Construction Co., Ltd., which is dedicated to the production of purification equipment, we are well aware that there are significant differences in purification requirements among animal laboratories of different scales. Next, we will analyze in detail the specific influence of laboratory scale on the selection of purification equipment for animal laboratories.

Small-scale animal laboratories usually have limited space and may only be used for some basic and small-scale experimental projects, with a relatively small number of laboratory animals.

Due to the small space, the demand for fresh air is relatively low, and a more compact fresh air treatment unit can be selected. This type of unit occupies a small area, can meet the basic fresh air requirements of the laboratory, and will not take up too much valuable space. For example, a small integrated fresh air unit with an air volume of 1,000 - 3,000 cubic meters per hour can effectively filter outdoor air and is convenient for installation and maintenance. In terms of filter configuration, primary and medium - efficiency filters are sufficient to meet the daily air filtration needs, removing common large - particle pollutants in the air such as dust and pollen.

Small - scale laboratories also have strict requirements for temperature and humidity control accuracy. However, due to the small space, the heat load is relatively low. A small air - cooled air - conditioning unit can be selected. Its refrigeration and heating capacity are moderate and can accurately regulate the indoor temperature within the appropriate range of 20 - 26°C and the relative humidity within 40% - 70%. High - precision wall - mounted temperature and humidity sensors can be selected and evenly distributed at key positions in the laboratory to monitor environmental parameters in real - time and ensure the stability of the experimental environment.

The size of the transfer window and air shower can be selected according to the size of the laboratory door and the frequency of personnel and item entry and exit. A small - sized but fully functional transfer window can meet the needs of small - scale laboratories to transfer items between different clean areas and effectively prevent cross - contamination. A small air shower can meet the dust - removal requirements of a small number of experimental personnel before entering the clean area, and the air shower time and wind speed can be adjusted according to the actual situation.

Medium - scale animal laboratories are of a moderate size, with relatively complex experimental projects and an increased number of animals.

The fresh air system needs to have a larger air volume and more efficient filtration capacity. A combined fresh air air - conditioning unit can be used, and its air volume is generally 3,000 - 10,000 cubic meters per hour, which can better adapt to the space and personnel activities in medium - scale laboratories. In terms of the filtration system, in addition to primary and medium - efficiency filters, high - efficiency filters need to be configured to ensure that the air sent into the laboratory reaches a higher purification standard and meets the strict requirements of the experiment for air quality. The selection of exhaust fans should be reasonably configured according to the amount of exhaust gas generated in the laboratory to ensure that the odors and harmful gases generated during the experiment can be discharged in a timely manner.

Considering the relatively large space of medium - scale laboratories and the uneven distribution of heat load, a water - cooled air - conditioning unit is advisable. Its refrigeration and heating capacity are stronger, and it can achieve precise temperature and humidity regulation in different areas through zonal control. In terms of temperature and humidity monitoring, a multi - point distributed sensor network can be used in combination with an intelligent control system to collect and analyze temperature and humidity data in each area in real - time and automatically adjust the operating parameters of the air - conditioning unit to maintain the stability of the entire laboratory environment.

The transfer window and air shower need to be selected in a larger size to adapt to the frequent entry and exit of personnel and items. The transfer window can be equipped with a double - door interlock function to further improve its isolation effect. The internal space of the air shower should be spacious enough to ensure that multiple people can perform the air shower operation at the same time, improving work efficiency. At the same time, an intelligent induction system can be equipped to automatically detect the entry of personnel and start the air shower program.

Large - scale animal laboratories undertake large - scale and comprehensive experimental tasks, with a wide variety and large number of laboratory animals, and have extremely high requirements for purification equipment.

The fresh air system needs to be equipped with a large - scale air treatment unit, and the air volume can reach more than 10,000 cubic meters per hour to meet the fresh air needs of a large - area space and a large number of personnel and animals. The filtration system should adopt multi - stage high - efficiency filtration, including primary, medium, sub - high - efficiency, and high - efficiency filters, to ensure that almost all dust particles and microorganisms in the air are filtered out and maintain a high cleanliness level in the experimental environment. The exhaust fan should have a strong exhaust capacity, and at the same time, an exhaust gas treatment device should be considered to purify the harmful exhaust gas generated by the experiment before discharging it to avoid environmental pollution.

Due to the large space and multiple functional areas of large - scale laboratories, a centralized central air - conditioning system needs to be adopted and combined with a precise zonal control system. By reasonably dividing the air - conditioning areas, the temperature and humidity of different functional areas (such as the animal breeding area, experimental operation area, equipment maintenance area, etc.) can be independently regulated to meet the different environmental requirements of each area. The temperature and humidity monitoring adopts a more intelligent and automated system, and big data analysis technology is used to optimize the operation of the air - conditioning system in real - time to ensure that the entire laboratory environment is always in the best state.

The transfer window and air shower should be selected in an extra - large size. The transfer window can be designed as a passage - type to facilitate the rapid transfer of large - scale experimental equipment and a large number of items. The air shower can be set as a multi - person parallel passage, equipped with high - speed and large - flow air shower nozzles to ensure that the personnel and items entering the clean area are thoroughly cleaned. In addition, large - scale laboratories may also need to be equipped with special purification equipment for the animal transportation passage to ensure the cleanliness of the environment in which laboratory animals are located during transportation.
