| Outline of Final Research Achievements |
Evaporative cooling techniques by spraying mist water have been attracted attention as a mitigation measure of the warming in urban area. However, the concrete way of mist control is still unknown. We proposed a temperature measuring method using the sound virtual temperature of the sonic anemometer-thermometer as a proper air-temperature measuring method for the investigation of water mist cooling. And in order to evaluate the psychological influence of water mist evaporation, subjective experiments were conducted in the outdoor space.
Perceived coolness by mist spraying is affected by not only air temperature drop but direct wetting of skin. Besides, in outdoor environment, the turbulence of natural wind makes air temperature varied frequently around spraying nozzles. So the rapid response method is absolutely required for the evaluation of thermal comfort.
