Summary

ACCORDING TO THE UNSTEADY STATE CALCULATION METHOD OF ROOM TEMPERATURE AND HEAT EXTRACTION IN A MULTI-ROOM BUILDING WHOSE ROOF SURFACE IS WET BY ROOF SPRAYING, SIMULATION HAS BEEN MADE IN A MODEL HOUSE AND THETHERMAL EFFECT OF ROOF SPRAYING IS EXAMINED AND COMPARED WITH ONE WITHOUT ROOF SPRAYING. AS THE RESULT OF THE SIMULATION AND WITH THE USE OF THERMAL COOLING STORAGE OF THE BUILDING STRUCTURE BY ROOF SPRAYING THE THERMAL ENVIRONMENT OF THE ROOM IS CLEARLY IMPROVED AND NATURAL COOLING HOURS ARE LENGTHENED. FURTHER EFFECTIVENESS OF THE SIMPLIFIED CALCULATION METHOD, WHICH INCLUDES APPROXIMATE LINEARIZATION OF HEAT TRANSFER RELATED TO MASS TRANSFER PHENOMENON FROM THE ROOF SURFACE IS PROVED BY ANALYZING THE ACCURACY OF THE RESULTS AND TIME REQUIRED IN THE CALCULATION OF ROOM TEMPERATURE AND HEAT EXTRACTION.
