Outline of Final Research Achievements

The objective of this study is to develop a high performance window, heat exchange type airflow window (H-AFW) which allows the heat exchange ventilation having energy saving and improvement of thermal environment. Firstly, we investigated the high performance of H-AFW under the dual mode to supply and exhaust air at the same time by model experiments. As a result of experiments, the dual mode of H-AFW showed relatively low power consumption in comparison with the other modes, supply and exhaust modes. Secondly, we investigated the basic characteristics of internal airflow inside a H-AFW by PIV (Particle Image Velocimetry) analysis. Finaly, we proposed an overall thermal performance evaluation method, optimal control and design method.
