This article presents a combined absorption-desiccant high performance airconditioning system suitable for hot humid areas. A LiBr-H2O absorption machine is powered by medium concentrators with a collection temperature of 140°C. The heat released in the absorption system condenser at 75°C is used for firing a silica gel (desiccant) dehumidifier. This consists of 2 silica gel beds of the cross flow type working alternatively in series with the absorption machine one bed at a time.
