|
|
This study evaporative cooling system a heat wave climate change and reduction of the inside and outside thermal
environment change research. Measurement items included micro meteorological phenomena and measured comfort indices.
A micro meteorograph of temperature, relative humidity, surface temperature, and the comfort indices of WBGT, UTCI, and
PMV were measured. The difference in inside and outside temperatures were compared for different land types, with the
largest difference found in Type A (4.81℃), followed by Type B (4.40℃ ) and Type C (3.12℃). Relative humidity was about
10.43% higher inside due to water injection by the evaporative cooling system. Surface temperature was inside about 6.60℃ higher than the outside all types. WBGT were Type A (3.50℃) > Type B (2.71℃) > Type C (1.88℃). UTCI was low heat
stress inside than outside all types. PMV was analysed Type C for inside predicted percentage of dissatisfied 75%, other types was percentage of dissatisfied 100% by inside and outside. Correlation analysis between land cover type and temperature,surface temperature, pmv, utci. T-test analysed inside and outside temperature difference was significant in all types of land.
