Abstract
A combined structural support and solar energy system with parallel joists having tubular upper chords defining conduits through which a fluid circulates for collection of solar energy and tubular lower chords defining conduits through which a fluid circulates for radiant heating and panel cooling.
Claims14
A structural support and solar energy system for use in building construction, said system comprising:
- (a) a plurality of joists, each said joist including a first chord through which a first fluid flows and a second chord through which a second fluid flows, and a web to which said first and second chords are attached;
- (b) a solar energy absorbing stratum mounted to said first chords for heating said first fluid in said first chords, said first chords defining a solar collector;
- (c) first pump means connected to said first chords for circulating said first fluid;
- (d) second pump means connected to said second chords for circulating said second fluid;
- and
- (e) heat exchanger means connected to said first chords and said second chords, said first heated fluid circulated through said heat exchanger means for transferring heat between said first fluid in said first chords and said second fluid in said second chords.

A structural support and solar energy system for use in building construction and comprising:
- (a) a plurality of joists, each said joist including first tubular chords, second tubular chords and a web, said first chords and said second chords mounted to said web in spaced relationship, said first chords configured to have a first fluid flow therein and said second chords configured to have a second fluid flow therein;
- (b) solar energy absorbing means mounted to said first chords for heating said first fluid in said first chords, said first chords constituting a solar collector;
- (c) first and second pump means connected to said first chords and said second chords, respectively, for circulating said first fluid in said first chords and said second fluid in said second chords;
- (d) heat exchanger means connected to said first and second chords for transferring heat between said first fluid in said first chords and said second fluid in said second chords;
- and
- (e) radiant heat means mounted to said second chords, said radiant heat means operative to transfer heat from said second fluid in said second chords to an area adjacent said radiant heat means.
