Fundamental study of direct contact cold energy release by flowing hot air through ice particles packed layer.

[In Japanese. / En japonais.]

Author(s) : AOYAMA S., INABA H.

Type of article: Article

Summary

The paper deals with the direct contact heat exchange characteristics between ice particles (average ice particle diameter: 3.10 mm) packed in a rectangular cold energy storage vessel and flowing hot air as a heat transfer medium. The hot air bubbles ascended in the fluidized ice particle layer, and were cooled down directly by the melting of ice particles. Finally, some empirical correlations for temperature efficiency, dehumidifying efficiency and the completion time of cold energy release were derived in terms of various nondimensional parameters.
