Method of Testing for Room Air Diffusion
Defines a repeatable method of testing the steady-state air diffusion performance of an air distribution system in occupied zones of building spaces. This method is based on air velocity and air temperature distributions at specified heating or cooling loads and operating conditions. Specifies equipment and procedures for measuring air speed and air temperature in occupied zones of building spaces. Applies to furnished or unfurnished spaces (actual or mock-up), with or without occupants. Applies to air distribution systems, including systems in which: a. air outlets are located inside, inside and outside, or outside of the occupied zone and b. local air velocities in the occupied zone are, or are not, under control by individual occupants. Dual units of measurement.
