Abstract
A building heat collection, storage and exchange system adapted for use with a solar collector, and featuring a specially designed heat storage tank. The closed system contains both liquid and gas, and is provided with drain reservoirs so that when heat is not being absorbed, the solar collector is drained, and the gas replaces the liquid in the collector. By the use of liquid intake and dispersal devices which eliminate turbulence, the heat storage tank maintains stable temperature zones. The most efficient extraction of stored heat is thus promoted.
Claims4
A closed building heating system containing a liquid and a gas and comprising
- a solar heat collector adapted to transfer solar energy to said liquid and heat said liquid thereby;
- liquid storage means adapted to contain a first quantity of said liquid with a first space, containing said gas, above said first quantity;
- first conduit means connecting said solar heat collector to said first space;
- drain reservoir means connected to said solar heat collector by second conduit means, said drain reservoir means being adapted to contain a second quantity of said liquid with a second space, containing said gas, above said second quantity;
- third conduit means connecting said liquid storage means to said drain reservoir means;
- gas conduit means connecting said first space in said liquid storage means to said second space in said drain reservoir means;
- pump means for urging said liquid through said closed system;
- said drain reservoir means being located such that when said pump means ceases operation, the force of gravity urges said liquid from said solar heat collector toward said drain reservoir means;
- and
- said third conduit means being adapted such that when said pump means ceases operation, flow of said liquid, between said first quantity in said liquid storage means and said second quantity in said drain reservoir means, is prevented.
