Optimization of adsorption dynamics in adsorptive chillers: Loose grains configuration

Dynamic performance of adsorption chillers (ACs) with adsorbent beds of loose grains is addressed in this paper. Temporal evolution of quasi-isobaric ad-/desorption curves for simple bed configuration of n-layers of loose grains (n = 1, 2, 4, and 8) located on a heat transfer metal support is studied. The support is subjected to fast temperature drop (50 °C → 30 °C) or jump (58 °C → 80 °C) typical for AC cycles. The size d of Fuji silica RD grains is varied from 0.2 to 1.8 mm.
