Abstract
Abstract The purpose of this study is to analyze the indoor temperature distribution of a room controlled by a personaland portable cooler. As an energy saving strategy, the personal air-conditioning or task conditioning system was developedand installed in office buildings in the 90 s. Many research results regarding the personal air-conditioning (PAC) system were focused on thermal comfort, localized ventilation efficiency and energy savings. However, the conventional PACs wereonly developed for application in office buildings. In this study, as a type of PAC, a portable cooler was analyzed in termsof indoor temperature distribution changes with the passage of time. The measurement was performed in a bedroom in an apartment house. The results showed that indoor temperature was controlled at about 24 ℃ around the human body. However,the ambient zone up to 1.5 m away from the the human body stayed at about 27.5 ℃ .
