Abstract
A transparent thermal panel is formed by two panes of glass each curved concentrically about one axis to form a section of a cylinder, and each being sealed at their edges. The envelope thus produced is evacuated. The evacuated glass envelope is attached to the uprights of a frame using a torsioned clamp which counteracts the bending stresses created by the vacuum in the glass envelope. Two such evacuated glass envelopes may be joined together and a solar collector placed between them. Combinations of one or both of the thermal panel and the solar collector may be used to cover the outside of a building. Coating the interior of the panels with a low emissivity material provides for increased R value.
Claims4
A window module comprising:
- a rectangular frame having first and second posts forming opposite parallel sides of the rectangular frame;
- an evacuated glass envelope having first and second parallel edges and having a first axis parallel to the first and second parallel edges, the glass envelope being formed by inner and outer panes curved in the same direction about the first axis and being sealed about their respective peripheries;
- first and second torsion means connected to the first and second posts respectively and to the first and second parallel edges of the glass envelope respectively for placing torsional forces on the glass envelope to balance the compressional and tensional forces in the outer and inner panes respectively.
