Study on air type wall surface solar heat collection system - 2nd report: Heat collection quality experiment of back sucking system

摘要

Previous 1st paper reported the surface sucking system which was developed (thin ventilation layer) concerning heat collection quality experiment. This 2nd paper reports concerning the heat collection quality experiment which keeps adding new back sucking system. Feature of new structure is to be able to close airtight glass lower adiabatic air layer in case of glass equipped specification.
