Adsorption Chillers - Hot Water Driven Solid State Cooling Machines

The history of adsorption dates back to 1848 when Faraday produced cooling using adsorption refrigeration phenomena, using silver chloride to adsorb ammonia. By the late 1800s, liquid ammonia absorption refrigerators were commonplace. Even Albert Einstein and his former student, Hungarian-born American physicist Leo Szilard first patented their own design for an absorption refrigeration device in 1928. In the 1960s, commercial absorption chillers using lithium bromide salt and water were commercialized, but were found to be difficult to operate with high maintenance costs.
