Dynamic simulation of combination of evaporative cooling with cooled ceiling system for office room cooling

In view of the emerging radiant cooling technologies in the European market, a dynamic building thermal analysis program ACCURACY is enhanced to be able to do cooling-load calculations and annual energy analysis for rooms with cooled ceiling climate system. The program was validated against the experimental investigation of the dynamic response of a test room to step heating and step cooling. Specifically, the validated program is used to perform a simulation of the combination of evaporative cooling with cooled ceiling technique for office building cooling purpose. The paper will present the construction principles of the program as well as the simulation results.
