Abstract
This paper provides examines sustainable personal cooling systems. The impact of micro-fan configuration and inflow airspeed was tested. First, three different types of test models-a garment with side seam micro-fans, scatter-fans, and bottom-fans, was used to analyze and compare the heat transfer characteristic. Second, a new index of convective heat transfer was used to evaluate the cooling performance of these models. Third, the selected model was calculated with three different inflow properties, and the performance of efficiency and energy saving was analyzed. The results show that the bottom-fans model yields the best performance both on efficiency and cooling effect. The evaluation of thermal environment shows that the defined indexes are reliable to reflect heat transfer characteristics in the air gap. The comparison study of different airspeeds shows that the inflow air velocity should be set at a suitable range due to the view of energy saving.
