A numerical study of the double-glazed solar air heater (DG-SAH) performance using optimized gas-filled interspaces

open access: yesCase Studies in Thermal Engineering, 2022
The reduction of energy losses and destroyed exergy requires the optimization of the double-glazing space. The poor thermophysical characteristics of the air are a limiting factor in the attenuation of heat loss through the double-glazing of the solar ...
