B.4 air samplers B.4.1 air samplers are used to extract a copy into the air homogeneous sample of air-cooled heat exchanger coil. Typical air sampler structure as shown in Figure B.1. Generally made of durable stainless steel, plastics or other suitable material, and its branches shall holes with an appropriate interval, the size should be away from pipes through the hole size to guarantee that all offer the same air holes so as to maintain the static pressure recovery in a branch pipe and dry pipe effect. By sampling the average minimum speed would be 0.75 m/s. The sampler component should have a tube-like interface, used in sampling air ducts connected to the sampling and measurement of temperature and humidity on the box.

B.4 air samplers requirements
B.4.1 air samplers for drawing a sample gas stream into the homogeneous air-cooled heat exchanger coil. Typical air samplers structure shown in Figure B.1. Usually made of stainless steel, plastic or other suitable durable material, the manifold shall be provided with holes at appropriate intervals, its size should be away from the trunk by increasing the pore size to ensure that provide the same airflow in all wells, in order to maintain the manifold and dry pipe static pressure recovery effect. By sampling holes should average minimum speed of 0.75 m / s. The sampler should have a tubular component interface for sampling duct is connected to the sampling and measurement of temperature and humidity on the cartridge.

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.
