An advanced solid sorption chiller using SWS-1L

In this paper, the experimental testing on an advanced solid sorption chiller based on a heat exchanger coated with a compact layer of SWS-1L (CaCl2 in mesoporous silica gel) is presented. The experimental results showed a specific power of 150–200 W/kg of adsorbent and a cycle time of 10–20 min. These values are sensibly better (i.e. one order of magnitude different) than those measured in the same unit working with a SWS-1L pelletised bed. The cooling COP ranged between 0.15 and 0.3, depending on the operating conditions.
