Study of Transparent Adiabatic Wall

Abstract

The authors investigated the characteristcs of transparent adiabatic walls which had heat reflecting film.
16 wall models were prepared for testing, 11 of them belonged to the type consisting of glass plus heat reflecting film, the others, the type consisting of plastic film plus heat reflecting film.
All models were tested by means of a thermal box and a net-radiometer, so overall heat transmission through the wall could be resolved into it's radiant component and it's convective component.
The optimum layout of the heat reflecting film was obtained so as to minimize radiant heat transmission in the wall.
A model superior to the usual system, i. e. double courtains, was recongnized from various viewpoints (transparancy, thermal insullation, sun screening, static, etc.)
Gases suitable for use on minimizing gas heat transmission in the wall were identified by tests made with the gas enclosure.
