“…Also they found that when using the composite adsorbent, the coefficient of performance and the specific cooling power could be increased by 51% and 38.4%, respectively, compared when using the regular density silica gel in the four adsorbers. Wang et al [30] have conducted a study on the adsorption characteristics of the adsorption refrigeration working pairs, using alkaline-earth metal chlorides Fig. 10.…”

“…With the purpose of solving the above problems, numerous investigations related to composite adsorbents have been conducted recently. Up to now, the most common type of chemical adsorbent that used to synthesize composite adsorbents is CaCl 2 , combined with a porous matrix such as alumina [21], vermiculite [21], activated carbon [22] [23], activated carbon fibre [24], expanded graphite [25], CaSO 4 [26]. Results of these researches shown that higher system performances could be achieved by the use of composite adsorbents as the enhancement of heat and mass transfer.…”

An experimental study of the adsorption performances of NH 3 on several commercial activated carbons was described. Firstly, the specific surface area, pore size distribution and morphological structure of the activated carbons have been characterized by N 2 adsorption, Scanning Electron Microscope (SEM), and X-ray diffraction (XRD). The adsorption capacities of four kinds of activated carbons were compared based on adsorption isotherms at 30˚C. Results show that a type of activated carbon MSC30 with high adsorption capacity of NH 3 is a promising adsorbent for NH 3 because of its large specific surface area and high pore volume. Secondly, the effect of adsorption temperature on the adsorption capacity of NH 3 on MSC30 was investigated. A modified Dubinin-Astakhov equation was employed to describe the adsorption isotherms, with the reliability and accuracy evaluation. The isosteric heat of adsorption of MSC30-NH 3 as a function of the amount adsorbed was calculated applying the Clausius-Clapeyron equation with isotherms obtained at 20˚C and 30˚C. Thirdly, a packed-bed type adsorber was used to evaluate the influence of cycle time on the system cooling performance (coefficient of performance, specific cooling performance, and volumetric cooling performance) of the MSC30-NH 3 pair at the evaporating temperatures of 5˚C, 10˚C and 15˚C with a fixed adsorption/condensing temperature and desorption temperature of 30˚C and 80˚C, respectively. Finally, a long term operation without degradation for MSC30-NH 3 adsorption was experimentally demonstrated from the 80 consecutive adsorption-desorption cycles.

“…Wang [11] presented a measurement device called the isochoric adsorption character measurement to measure the adsorption characteristics and this measurement device has a higher accuracy than the prevalent method. Wang [12] conducted a study on the adsorption characteristics of the adsorption refrigeration working pairs using alkaline-Earth metal chlorides as adsorbents and ammonia as the refrigerant. The adsorbents of CaCl 2 , SrCl 2 , MgCl 2 , and BaCl 2 were discussed.…”

Featured Application: The study is mainly used in areas where water is scarce, adsorbents adsorb water from the air, and are then desorbed.Abstract: A new experimental device which tests the adsorption performance of the 13X/CaCl 2 composite adsorbent under vacuum conditions was established. In this device, heat transfer characteristics in the adsorbent bed have a great influence on the adsorbent performance, the temperature of the bottom outside bed is very close to the temperature of the bottom inside bed and the temperature difference between them at the end of heating and cooling are 5.66 • C and 0.303 • C, respectively. The following conclusions could be drawn: the equilibrium water uptake of composite adsorbent CA10X (zeolite 13X impregnated with 10 wt % CaCl 2 solution) was increased 5.7% compared with that of 13X, and the water uptake was 0.37 g/g. The composite adsorbent CA10X has a better performance in the adsorption refrigeration system.
