Abstrakt

The room ventilation is investigated for three different air terminal devices under isothermal conditions.
Velocity distribution in the occupied zone is measured for each air terminal device at different air exchange rates. The maximum air exchange rate is determined on the base of both the throw of the jets and the comfort requirements applied to measured air velocities in the occupied zone.
Normalized concentration distribution in the test room is determined along a vertical line through the middle of the room as a function of the air exchange rate and the density of the tracer gas.
The relative ventilation efficiency, <E > , based on the room average concentration is also determined as a function of the air exchange rate and the density of the tracer gas.
The influence from the position of the return opening on the relative ventilation efficiency is found for one air terminal device.
