Design and Experiment of High-Temperature Tubular Heat Accumulator Using the Latent Fusion Heat of ''Zamak 3'' Alloy.

摘要

The general design of the prototype heat accumulator using the aluminium and zinc alloy Zamak 3 encapsulated, operating between 300 exp 0 C and 500 exp 0 C is presented. The energy is stored in the form of latent heat of fusion in one tonne of Zamak contained in a vertical tube array. The heat carrier fluid is air. A numerical approximation of its operation by means of a simplified simulation model is studied. The presentation and the analysis of actual performance figures, for the prototype under different operating conditions are given. Modifications to improve the performance are proposed.
