Heat/cold accumulator for low-tariff econ- - omy

摘要

Liquid passes through the accumulator to be heated or cooled. A fusible accumulator mass is carried in envelope(s) and is in heat exchange with the liquid, and can be heated or cooled by a device which is not in heat exchange with the liquid. The outer surface of the envelopes efine together an assembly of channels in the reservoir to cause, by gravity, a circulation of the liquid, which absorbs or gives up heat to the accumulator masses.
