Abstract

This final report presents results of a study which had two objectives: + test the feasibility of the zeolithe - H-2O pair to medium size solar powered cold stores + find a new pair so as to realize a solar powered ice maker. The work presented in that report enables us to give some conclusions. The zeolite - water pair allows to build solar powered units ranging from small individual refrigerators (for camping or for vaccine storage) to medium size cold stores. In our study, we did not notice any important size effect between our small units and the 12 m**3 (with 20 m**2 solar collectors) unit. The activated carbon - methanol pair can be used as well as the zeolithe - water pair for conservation at + 5 degrees C: we think that it is only after a value analysis study that a good choice between the two pairs will be possible. But moreover, the activated carbon pair can be used to fire a solar powered ice maker. The scale which seems to be realistic for the application of that pair ranges from very small units to units producing some hundreds of kilogrammes (or some thousands) of ice per day. Finally, let us emphasize the work presented in that report on the response of a solar collector filled with the reactive solid to a variable incident solar flux. This point is very important because we are now able to develop a computer simulation which simulates the working of such units in actual conditions, whatever those conditions. This is a precious tool to optimize those units from a technical point of view as well as from an economical point of view.
