实验动物设施的回风系统一般是采用夹壁回风或彩钢板回风墙。这两种方法造价高且需占用饲养室的有效使用面积。作者采用薄板材钉在墙角形成三角回风道,现浇楼面预留相应的三角回风口,饲养室三角回风道向上通过三角回风口进入设备层回风系统的方法。饲养室三角回风道下部开长方形回风口,安装初效过滤材料,可按时拆下清洗。上述方法使饲养室回风道工程造价降低约90％,饲养室使用面积提高了1.5％,且净化测试结果达到1万级。

Laboratory animal facilities return air system is generally used wall return air or color steel return air wall. Both of these methods are costly and require efficient use of the breeding room. The author uses a thin plate nail to form a triangular return air duct in the corner, and the cast-in-place floor reserves the corresponding triangular air return, and the triangular air return in the breeding room enters the return air system of the equipment through the triangular air return. Breeding room triangle back to the lower part of the air duct opening rectangular return airway, the installation of early filter material can be removed on time cleaning. The above method reduces the construction cost of the return air duct of the breeding room by about 90%, the area of ​​the breeding room by 1.5% and the purification test result of 10,000 levels.
