Performance analysis of an adsorption refrigerator using activated carbon in a compound adsorbent

A review on the use of calcium chloride in applied thermal engineering

“…The same mass ratio of calcium chloride and activated carbon (4:1) was adopted as the best in the design of another calcium chloride-based composite in which EG was replaced by activated carbon [22]. A cement binder was used for the consolidation and the mass ratio of CaCl 2 , activated carbon and cement in the consolidated composite was finally 16:4:1.…”

“…-A highly hygroscopic desiccating and sorption capacity [21,22], in solid or liquid state. This property is widely used in industry, laboratories, commercial and domestic buildings: it has been shown that anhydrous CaCl 2 could adsorb up to 90% of its own weight in moisture (water vapour) at ambient temperature and pressure [23].…”

“…-Possible liquefaction of the material after absorbing a certain amount of water [24] -Excessive swelling/expansion (2:1 [24]) and agglomeration in particular when used in absorption cycle with ammonia [32,22,24]: this degrades heat and mass transfer and results in the decrease of reaction rate after several cycles [33] -Depending on the use, disintegration/decomposition/deterioration after several operating cycles [25,32,34] when no special measure is taken [13] -Corrosive to certain metals in the presence of excess oxygen because of chloride-induced corrosion [35]. However, this corrosion problem is practically no real threat any more when the process is run under near vacuum conditions (limited air or oxygen in an adsorber [35]), which is usually the case.…”

A review of emerging technologies for food refrigeration applications

“…Research and development is also underway to produce systems for refrigeration applications. Research prototypes for refrigeration temperatures down to -25°C are currently in operation or under development [11,12,13].…”

Adsorption isotherms and Sips models of nitrogen, methane, ethane, and propane on commercial activated carbons and polyvinylidene chloride

“…These compressors can establish a pressurized gas flow by the cyclic adsorption and desorption of a working gas at a sorber (Prasad et al 1996;Banker et al 2004;Lu et al 2006). These sorption compressors are thermally driven and operate without moving parts; meaning they are highly reliable, long life, and vibration free.…”
