A chemical heat pump using carbon fibers as additive. Part II: study of constraint parameters

The different parameters which are able to modify a chemical heat pump perf ormance when carbon fibers are used as additive have been studied. The comp ression study gave an optimal point corresponding to the best kinetic resul t. In addition it was shown that the best kinetic results are also obtained when fibers are put radially into the cylindrical reactor. The heat exchan ge coefficient was measured: h = 110 W m(-2) K-1. This high value has been obtained because of the good contact between reagent bed and reactor wall, due to the presence of carbon fibers. (C) 1999 Elsevier Science Ltd. All ri ghts reserved.
