Summary

In the paper, the authors experimentally examine the influences of position and capacity of cooling panel, and supplying and exhausting conditions on the air and thermal environment of the room. The result of model experiment shows that floor cooling panel system causes stronger vertical temperature distribution, and more uneven radiative environment than ceiling cooling panel. Reducing the temperature difference between the exhaust and supply air and decreasing the cooling panel surface temperature is effective for reducing the down draft risk in an occupied zone. When the exhaust opening is set above the window, the upstream heated by the wind is directly exhausted without diffusion and thus the heat load from the window has little influence on the thermal environment of the room.
