폭염저감기술에 따른 외부공간의 기온 저감에 대한 연구 : 쿨링포그의 더위 저감효과 검증을 위한 실증실험

Abstract

To provide Social Overhead Capital (SOC) for daily human lives, local governments are preparing various measures against heat waves, such as supplying Heat Wave Mitigation Facilities and supporting the vulnerable. Cooling Fog is a recent trend of Heat Wave Mitigation Facilities, but South Korea has limited data on reducing body temperature through direct application of cooling matter on the body, and most research on Cooling Fog has addressed technical aspects. In this study, to confirm the effect of Cooling Fog on the human body, experiments were conducted. First, the change of environmental factors in the space around the Cooling Fog was compared with an unaffected area. Second, a survey was conducted targeting people who use Cooling Fog to review its sensory effects. Finally, the effect of Cooling Fog was quantitatively verified by linking and analyzing related data. The air temperature and radiation temperature were lower in the area of Cooling Fog, but humidity was high. The sensory survey confirmed that Cooling Fog produced a sensation of cooler temperature compared to the area without Cooling Fog, as assessed using Thermal Sensation Vote (TSV), Heat Score, and Apparent Temperature (AT). In addition, the area of Cooling Fog was reported to have higher Thermal Comfort than the area without.
