The emphasis on alternate sources of energy has intensified interest in solar energy. Since solar energy is generally collected as heat, the absorption unit appears to be a promising candidate for the solar cooling of buildings. The fluid temperatures usually available from flat plate collectors are too low to permit the use of air-cooled units. Aqueous lithium bromide and aqua ammonia, the only commercially successful absorption cycles, are compared as water-cooled water chillers. Either cycle can be used; however, the bromide unit has a higher efficiency and much lower pump work than the ammonia cycle.
