Experiment on a New Adsorption Bed about Adsorption Refrigeration Driven by Solar Energy

Solar refrigeration represents an important application of solar energy due to the excellent matching between the high sun shine and the refrigeration needs. The absorber heated by solar energy contains an activated carbon-ammonia pair. Comparing and analyzing the performance of some usually used working pairs, the active carbon-ammonia was selected as the best refrigeration working pairs in this thesis. Several typical structure adsorbent beds had been analyzed, the key problems which should be solved in designing adsorbent bed had been indicated and the constraint conditions of designing adsorbent bed had been generalized. Based on the above analysis, a new style structure adsorbent bed had been designed, which has some characters as follows: compact structure, good performance in bearing strength, high efficiency in heat & mass transfer, great packing amount of adsorbent, and uniform temperature field in the bed.
