Self-contained solar heating system separate from another energy source

The invention relates to a solar heating and sanitary hot water producing system separate from another energy source with long-term (interseasonal) storage and centralized management of the production and use, using a heat transfer fluid kept at high temperatures. The system consists of at least one long-term interseasonal heat transfer fluid storage tank (R1), a centralized management system optimizing production and use according to predetermined parameters, an automatic emptying and filling system (4), and a set of motorized valves and circulation pumps controlled by the management system. The system is linked to the heating network (2) (floor heating, radiators, fan coil units, etc.). The solar thermal collectors (1) heat the heat transfer fluid, which may be used for immediate supply to the heating network (2), stored in the tanks (R1), or used in a sanitary hot water processor (3). In the absence of solar production, the management system uses the stored fluid to meet heating demands. The invention can be used for individual or collective sanitary or industrial hot water heating.

Method of storing and abstracting heat and cold in or from an aquifer

The present invention relates to a method of storing and abstracting heat and coldness in or from an aquifer. In accordance with the invention, there is a third body of water (6) at a temperature between Tl and Th in addition to a first body of water (4) at a first, high temperature Th and a second body of water (7) at a second, low temperature Tl. When abstracting coldness from the second body of water (7) the temperature of the water is raised to a temperature Tm2 that lies between Th and Tl, and when abstracting heat from water having the first temperature, the temperature is lowered to Tm1. The water having temperature Tm1 or Tm2 is stored in the third body of water (6). The invention makes it possible to considerably reduce the capital outlay and thereby to improve the cost-effectiveness of this form of energy saving.
