The purpose of this study is to design a hybrid system which is a combinati
on of radiant cooling and low temperature air conditioning integrated with
ice storage system. This paper reports the observed thermal environment of
the chamber and results of experiments with subjects to grasp the optimum t
emperature and humidity of the room. In addition, a feasibility analysis fo
r the hybrid system using conditioned air as a refrigerant was also studied
with a computer calculations. This system produces comfortable environment
and it is also possible to save energy consumption due to the reduction of
electricity that could have been used on a fan. (C) 1999 Elsevier Science
