Abstract
For the purpose of large reduction of the electricity consumption, a portable personal cooling system was developed, which cooled only the human body instead of a conventional air-conditioner which cooled the whole conventional room. Various methods including a cape model, a vest model were produced experimentally and were evaluated. Then, it was shown that a method to absorb heat with peltier device from a neck and to radiate heat by water cooling was most suitable. Moreover, a heat transfer model of water-cooling was built, and a design indicator for optimizing was shown.
