B.4空气取样器要求
B.4.1空气取样器用于抽取一份进入风冷换热器盘管的气流均匀样品。典型空气取样器结构见图B.1。一般用不锈钢、塑料或其他合适的耐久材料制成，其支管应带有适当间隔的孔，其尺寸应在远离干管时通过增加孔尺寸来保证在所有孔中提供相同的气流，从而维持支管和干管中的静压恢复效应。通过取样器孔的平均最小速度应为0.75 m/s。该取样器组件应有一个管状接口，用于取样风管连接到取样器和温湿度测定盒上。

B.4 air sampler requirementsB.4.1 air sampler for extracting a into the air-cooled heat exchanger coil airflow uniformity samples. A typical air sampler structure shown in figure B.1. General use of stainless steel, plastic or other suitable durable material, the branch should be with the appropriate interval of hole, its size should be far away from the stem tube by increasing the pore size to ensure the same airflow in all holes, thereby maintaining the branch and stem the recovery effect of the static pressure pipe. The average minimum speed sampler hole should be 0.75 m/s. The sampler should have a tubular component interface, used for sampling of wind pipe connected to the sampler and the temperature and humidity determination box.
