We constructed the operation control system of radiant cooling and heating system by using ceiling panel for the purpose of providing indoor environment with thermal comfort. The control system, which controlled the supply temperature or the flow rate of heat supply water for radiant panel optimally, was able to maintain the constant mean radiant temperature and to improve the follow-up ability for heat load fluctuation. In this paper, we reported the results of field measurement in our demonstration room and we described the effectiveness of the system from the viewpoints of indoor thermal environment and energy efficiency ratio.
