Abstract

A thermal insulation system includes an evacuated structure including an internal space in which a vacuum is sustained by a vacuum pump operating when it is determined that a pressure within the internal space has risen to a predetermined level. In one embodiment, such a system is used within a dome structure extending over and around a heat receiving structure within a solar heating system.

[0002] Not ApplicableBACKGROUND OF THE INVENTION

[0003] 1. Field of the Invention

[0004] This invention relates to thermal insulation systems, more particularly to such systems including evacuated structures, and yet more particularly to the use of such systems to allow heat retention within solar heat collectors.

[0005] double glazed vacuum structures, and, more particularly, to such structures having a means for providing and maintaining a vacuum between spaced-apart glass sheets for thermally insulating solar heat collectors.

[0006] 2. Summary of the Background Information

[0007] A solar heat collector typically includes a heat receiving structure through which a fluid, such as water, is circulated to be heated by solar radiation. The heat receiving structure comprises elements such as piping, tubing, a reservoir tank, and a thermally conductive structure to absorb heat from radiant energy and to transmit the...
