| Abstract | In recent years, a new air-conditioning concept has emerged in Europe which has been
found to be well accepted. The new concept utilizes radiant panels for both heating and
cooling.
Using radiant cooling for air conditioning offers advantages over conventional heating,
ventilating and air-conditioning (HV AC) system. A good thermal comfort environment can be
achieved and air transported can be reduced. However, in a tropical climate, study on the
radiant cooling has not been conducted, although such method is perceived to offer good
potential. This thesis reports an experimental and analytical study of radiant cooling in an
experimental room in Energy Park, AIT.
It was found that the room were comfortably pleasant and slightly cool during the
morning. The mean radiant temperature was lower than the temperature of surfaces in the
room. This low mean radiant temperature resulted in lower operative temperature.
Condensation problem occurred when the panel was cooled down beyond the dew-point
temperature of the air in the room.
Physical measurements were made to assess cooling load on the radiant panel. A
mathematical model incorporating temperature variables was used to represent the cooling
load. The model proved to be accurate and useful and could be used to simulate the cooling
load. |
