Solid sorption cycles: A short history

摘要: Adsorption cycles for heat pumping or refrigeration might seem like a relatively new and minor interest in research. Fig. 1 from the International Web of Science shows numbers papers published over 30-year period to 2008. It would appear that there was no work done before 1978, but this is not case. The history solid sorption systems long, dating Faraday (1823). He used adsorption large amounts ammonia into silver chloride as basis thermal compressor obtain study liquid ammonia. With ammoniated one leg sealed bent glass tube, upon heating he could repeatedly drive out condense pure other leg. Although his purpose liquid, noted, “When allowed cool, immediately returns it, combining with producing original compound. During action curious combination effects takes place: absorbs ammonia, produced, temperature rising up nearly 100°, whilst few inches off, at opposite end considerable cold produced by evaporation fluid”. practical significance noted range refrigerating machines developed remainder century.
