Abstract
This paper describes the results of experiments in terms of the thermal environment near large outlets for natural ventilation. Four types of outlets were tested; outlets from the ceiling, tilting openable windows, the floor and the wall. Air temperature distributions and air velocity distributions were measured for different combinations of outlet air temperatures and outlet velocities. Destributions of 'draft rating', which indicates the percentage of the dissatisfied due to draught, are also evaluated. The measured results provides basic data for the thermal environment near large outlets for various combinations of outlet air temperature and velocities.
