Abstract:
A refrigeration capacity accumulator of the type comprising a set (6) of accumulation tubes (1) disposed in an isothermal enclosure (10), said tubes (1) being spaced apart and maintained substantially parallel to one another, each tube (1) of said set being closed at its ends (4, 5) and containing a primary static liquid (3) capable of transforming into ice during a cooling by a secondary refrigeration fluid (11) and/or of cooling a secondary, so-called utilization liquid (11), the secondary fluid and/or liquid circulating between the tubes (6), outside the latter, the circulation in the enclosure (10) of the secondary product (11) or the two secondary products (11) occurring between an inlet (12) and an outlet (13) located at two opposite ends of said enclosure, characterized in that (a) each tube is closed at each of its two ends (4, 5) by an internally concave wall, (b) each tube maintains an expansion space (1a) between the primary liquid (3) and its cylindrical wall (2), and (c) each tube is disposed horizontally within the enclosure (10).
