太陽光・熱ハイブリッドシステム内部における二相流の熱流動特性調査

抄録

Photovoltaic-thermal hybrid solar system consists of photovoltaic solar module and solar thermal collector. The hybrid system can generate electric and thermal energy simultaneously, and when also can recover the efficiency of electric power output to decrease the temperature of photovoltaic panel. In this study, for the purpose of improvement of heat efficiency in photovoltaic-thermal hybrid solar system, thermal dynamics characteristics of two phase flow (water + n-Hexane) was investigated. It was found that temperature at outlet of experimental apparatus is increasing with increasing mass flow rate. In addition, heat transfer was enhanced by changing from laminar flow to turbulent flow and emulsification of working fluid in high mass flow area.
