Abstract
A solar thermoaccumulator, including a parallel battery of closed-circuit vacuum solar pipes, and provided with a plurality of accumulation bulbs, which are either immersed in a primary conductive fluid that circulates in an annular chamber having an air space, whose internal wall is the containing wall of a reservoir containing a fluid to be heated; or are put in direct thermally conductive contact with tubular tangs that are attached to and inserted in a reservoir, is disclosed. The reservoir may be single reservoir, or may be associated with and sequentially in fluid communication with at least one other upstream, parallel aligned reservoir.
Claims14
A solar thermoaccumulator comprising:
- a plurality of closed-circuit vacuum solar tubes (7), each solar tube being coupled to at least one of a plurality of heat accumulation bulbs or condensers (6);
- at least one first reservoir (9, 9′) containing the fluid to be heated, circumscribed by a shell and provided with fluid feeding pipes (18) and discharge pipes (19) of the heated fluid, wherein each of the at least one first reservoir (9, 9′) containing the fluid to be heated is provided with a peripheral, annular, enveloping chamber (3) having an air space, whereto a primary conductive liquid is caused to flow, and the heat accumulation bulbs or condensers (6) are immersed in the primary conductive liquid, wherein the annular chamber (3) is circumscribed by an internal wall (8) in touch with the fluid to be heated, and by an external wall (1);
- and
- means to transfer heat from the heat accumulation bulbs or condensers (6) to the fluid to be heated;
- wherein the heat accumulation bulbs or condensers (6) are mounted throughout a lower longitudinal extension of the shell of the reservoir (9, 9′) containing the fluid to be heated.
