Abstract
Abstract A heat-protective building cladding unit in which a frame carries two spaced apart transparent sheets. One or more movable members are arranged in the space between the transparent sheets for selective movement. The movable member may thus be moved selectively to permit or prevent solar radiation from passing between the two transparent sheets. The unit is mounted to enclose a selected area of a building wall onto which a selective absorbing layer has been applied. Heat is conducted from the selective layer to the building interior by heat pipes or a circulating fluid.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
123 words
A solar heated, thermally protective building cladding comprising: a building having an outer wall; a portion of an outer surface of the wall being covered by a selective absorbing layer; a plurality of heat pipes disposed in the wall in thermal communication with the selective absorbing layer, the pipes extending between the layer and the interior of the building; a frame carrying two spaced-apart transparent sheets having in the space therebetween one or more movable members arranged for movement to selectively permit or prevent solar radiation from passing between said sheets; and the frame being mounted upon the outer wall of the building enclosing the layer so as to form an air space between the layer and the innermost of said transparent sheets.
Claim 2
Dependent Claim
123 words
A solar heated, thermally protective building cladding comprising: a building having an outer wall; a portion of an outer surface of the wall being covered by a selective absorbing layer; a plurality of heat pipes disposed in the wall in thermal communication with the selective absorbing layer, the pipes extending between the layer and the interior of the building; a frame carrying two spaced-apart transparent sheets having in the space therebetween one or more movable members arranged for movement to selectively permit or prevent solar radiation from passing between said sheets; and the frame being mounted upon the outer wall of the building enclosing the layer so as to form an air space between the layer and the innermost of said transparent sheets.
Claim 3
Dependent Claim
50 words
A cladding unit in accordance with claim 1 wherein said one or more movable members are elongate foil members between said transparent sheets and mounted on a roller so as to present either a reflective or a transparent portion thereof between said sheets in response to movement of the roller.
Claim 4
Dependent Claim
19 words
A cladding unit in accordance with claim 2 wherein said one or more movable members comprise a plastics material.
Claim 5
Dependent Claim
42 words
A cladding unit in accordance with claim 2 wherein said foil member is movable so as to present a reflective surface thereof towards one or towards the other of said transparent sheets, or to present only transparent portions thereof between said sheets.
Claim 6
Dependent Claim
64 words
A cladding unit in accordance with claim 1 wherein said one or more movable members comprises, between said sheets, a plurality of strips each having at least one reflective surface, said strips being mounted for movement about parallel axes between positions in which said reflective surfaces form a substantially continuous reflector and mutually parallel positions in which solar radiation may pass substantially uninterrupted therebetween.
Claim 7
Dependent Claim
18 words
A cladding unit in accordance with claim 1 wherein one of said sheets is opaque to ultra-violet light.
Claim 8
Dependent Claim
14 words
A cladding in accordance with claim 1 wherein said selective layer comprises copper monoxide.
Claim 9
Dependent Claim
16 words
A cladding in accordance with claim 1 wherein said heat pipes are inclined to the vertical.
Claim 10
Dependent Claim
41 words
A cladding in accordance with claim 1 wherein each said heat pipe includes an evaporation portion in thermal communication with said selective layer and a condenser portion thermally coupled to a heat exchanger serving to heat the space within the building.
Claim 11
Dependent Claim
20 words
A cladding in accordance with claim 9 wherein said heat exchanger is arranged to heat the air within the building.
Claim 12
Dependent Claim
24 words
A cladding in accordance with claim 9 wherein said heat exchanger is arranged to transfer heat into a water heating system for said building.
Claim 13
Dependent Claim
34 words
A cladding in accordance with claim 9 wherein the movement of said one or more movable members is effected by means of a servo mechanism responsive to the temperature inside and outside the building.
Claim 14
Dependent Claim
34 words
A cladding in accordance with claim 1 wherein the acutation of said one or more movable members is effected by means of a servo mechanism responsive to the temperature inside and outside the building.
