Résumé

The study shows that composites based on calcium chloride and lithium bromide as impregnated salts and different micro- and mesoporous silica gels as host matrices are able to absorb up to 0.75 g H2O per 1 g of dry sorbent. After presentation of sorption equilibrium curves, the thermodynamic performance, for their utilisation in heat pump and refrigeration systems, is calculated. These new materials can be operated with cycles whose maximum temperature is about 95 °C (for cooling) and 140 °C (for heating) that are lower than those for other pairs known so far. The COPs are considerably higher than those reported for the silica gel/water system.
