They can be classified into four categories: diffusers, grilles, registers, and terminals. Diffusers are devices that distribute conditioned air into a space with a high degree of mixing. Grilles are devices that allow air to pass through an opening with little or no change in direction. Registers are devices that combine a grille and a damper to control airflow. Terminals are devices that modulate airflow or temperature at the end of a duct. The performance of air outlets and air inlets can be measured by several parameters, such as airflow rate, pressure drop, throw distance, velocity profile, sound level, temperature distribution, entrainment ratio, induction ratio, discharge coefficient, effective area, etc. These parameters can affect indoor air quality and comfort by influencing factors such as ventilation effectiveness, thermal stratification, draft risk, noise level, etc. Ashrae Standard 70 2006 provides a method of testing the performance of air outlets and air inlets using laboratory or field measurements. The standard specifies the test procedures, equipment, and data analysis methods for different types of air outlets and air inlets. The standard also provides tables and charts for presenting and comparing the test results. ## Applications and Examples of Ashrae Standard 70 2006 Ashrae Standard 70 2006 can be used for various purposes by HVAC professionals.
