THEORETICAL AND EXPERIMENTAL STUDY OF A STORAGE SENSIBLE HEAT UNIT IN PERIODIC REGIME
Аннотация
We have undertaken to show theoretically and
experimentally that extracting the mean value of
a periodic thermic power source is possible. So
we have set up and tested in laboratory a reduced
time and space scale device simulating the behaviour
of an autonomous plant for an ideal situation
(regular day-light alternation). The thermal
storage unit serve to damp down the fluid temperature
oscillations at the exit. The air flowing
regime spread on a Reynolds scale from 1 500 to
8 000. The working periods range from 1/4 to 3
hours. As the storage unit constitutes the main
part of the loop we shall deal essentially with
the properties of its transfer function. At last
we indicate some experimental results about the
loop acting as a power filter.
