Vacuum glazing: Current performance and future prospects

Vacuum, 2008
The development of vacuum glazing is a significant advance in the area of low heat loss glazing systems with great potential to reduce building heating and when combined with solar control glazing, cooling loads. The basic concept of vacuum glazing is reviewed and the procedures and research undertaken in the development of both high-temperature and ...

Thermal outgassing of vacuum glazing

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 1999
Vacuum glazing consists of two sheets of glass separated by a narrow evacuated space. In this article we describe investigations of the causes of thermally induced degradation of vacuum glazing. It is shown that the rate of increase of pressure within the glazing during high temperature aging is mainly determined by the diffusion of water out of near ...

Getters for vacuum insulated glazing

Vacuum, 2018
Abstract The vacuum problem in sealed off chambers of VIGs type has been solved. The solution is based on two innovations. The first one is the usage of activationless getters in a form powders or granules of the composition Ca0.35Li0.45Mg0.20 instead of barium. The second one – the changed sequence of assembling the vacuum window at which the getter

Manufacture and cost of vacuum glazing

Fuel and Energy Abstracts, 1995
The vacuum glazing project at the University of Sydney has progressed to the point where the main features of the vacuum glazing design are determined well. Over 500 glazings with areas up to one square meter have been formed. The stresses to which these glazings are or may be exposed have been studied extensively.

Photodesorption of gases in vacuum glazing

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 2003
When samples of vacuum glazing are exposed to sunlight, the pressure within these devices is observed to increase. The major gas species released have been identified using mass spectroscopic techniques, and are found to be carbon monoxide and carbon dioxide rather than water vapor as in thermally degraded vacuum glazing. Different measuring techniques,

Evacuation and outgassing of vacuum glazing

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 2000
The evacuation and outgassing of vacuum glazing is studied by modeling and experimental methods. A two-dimensional finite difference method of modeling the pumpdown process is validated by comparison with a one dimensional, cylindrically symmetric finite difference method, and with measurements on experimental samples. In the absence of outgassing, the

Vacuum glazing units and solar collectors

Applied Solar Energy, 2008
Possible application of vacuum glazing (VG) units for transparent insulation of solar collectors (SC) to reduce their heat losses is considered. Taking into account the SC operating conditions, the heat insulating parameters of VG samples measuring 0.3 × 0.3 m2 and 0.5 × 0.5 m2 are experimentally studied and compared to those of double glazing (DG) of ...

Thermal performance of an electrochromic vacuum glazing

Energy Conversion and Management, 2006
Using a three-dimensional finite volume model, the thermal performance of an electrochromic vacuum glazing was simulated for insolation intensities between 0 and 1200 W m 2 . The electrochromic evacuated glazing simulated consisted of three glass panes 0.5 m by 0.5 m with a 0.12 mm wide evacuated space between two 4 mm thick panes supported by 0.32 mm ...
