为了避免回风格栅处可能出现的负压，采样管应该离格栅100-200毫米
• It is recommended that the sampling holes are positioned to face the direction of the greatest airflow path 建议采样孔朝向最大的气流方向 • Monitoring the exhaust of an AHU is not recommended as the filters can remove the presence of smoke 并不建议在AHU的送风口采样，因为空调的回风滤网已经将烟雾颗粒部分 过滤
NB: As a guide, NFPA 76 recommends 2 a maximum hole coverage of 0.4m (4ft2 ).

• The number of holes in the sampling pipework is determined by the aspirator’s capacity.
采样孔数量取决于气泵的能力 • A sampling coverage of 0.2m2 (2ft2 ) is recommended. 建议0.2m2每个孔
