Abstract
Abstract A system including a source of energy (for example, the solar pickup 14) and a closed circuit for a heat-carrying fluid including a storage (1, 10). The circuit provides a primary circuit (7, 13), the storage having a chamber sealed by a plurality of walls (4, 12) and a filling agent (6, 11) exhibiting a calorific capacity and thermal conductivity for heat transfer from the primary circuit to a second circuit (8) in heat exchange relation with the filling agent. The filling agent comprises a gel comprising an acrylic acid derivative.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
128 words
A storage for storing calorific energy, as may derive from a solar pickup including an insulating casing, a filling agent comprising at least partially a gel of an acrylic acid derivative base, heat-carrying fluid circuit means extending within said casing in thermal contact with said filling agent, said heat-carrying fluid circuit means comprising a primary circuit and a secondary circuit of conduits, one of which is for a heat-carrying fluid and the other of which is for a fluid to be heated, an auxiliary water storage, said heat-carrying fluid circuit means also in contact with water in said water storage, and valve means for circulating said heat-carrying fluid in said storage and/or auxiliary storage as a function of the respective temperatures of said heat-carrying fluid and said storages.
Claim 2
Dependent Claim
128 words
A storage for storing calorific energy, as may derive from a solar pickup including an insulating casing, a filling agent comprising at least partially a gel of an acrylic acid derivative base, heat-carrying fluid circuit means extending within said casing in thermal contact with said filling agent, said heat-carrying fluid circuit means comprising a primary circuit and a secondary circuit of conduits, one of which is for a heat-carrying fluid and the other of which is for a fluid to be heated, an auxiliary water storage, said heat-carrying fluid circuit means also in contact with water in said water storage, and valve means for circulating said heat-carrying fluid in said storage and/or auxiliary storage as a function of the respective temperatures of said heat-carrying fluid and said storages.
Claim 3
Dependent Claim
108 words
A storage for storing calorific energy, as may derive from a solar pickup including an insulating casing, a filling agent comprising at least partially a gel containing from about 85 to 90% by weight of water and about 15 to about 10% by weight or acrylic acid derivative base polymers, at least a heat-carrying fluid circuit in thermal contact with said filling agent, an auxiliary water storage, said heat-carrying fluid circuit also in contact with water in said water storage, and valve means for circulating said heat-carrying fluid in said storage and/or auxiliary storage as a function of the respective temperatures of said heat-carrying fluid and said storages.
Claim 4
Dependent Claim
108 words
A storage for storing calorific energy, as may derive from a solar pickup including an insulating casing, a filling agent comprising at least partially a gel containing from about 85 to 90% by weight of water and about 15 to about 10% by weight or acrylic acid derivative base polymers, at least a heat-carrying fluid circuit in thermal contact with said filling agent, an auxiliary water storage, said heat-carrying fluid circuit also in contact with water in said water storage, and valve means for circulating said heat-carrying fluid in said storage and/or auxiliary storage as a function of the respective temperatures of said heat-carrying fluid and said storages.
Claim 5
Dependent Claim
34 words
The storage according to one of claims 1 or 2 wherein said filling agent further comprises particulate, including pebbles and sand, and wherein said gel is mixed thoroughly within the interstices of said particulate.
