“…The dispersion of CaCl 2 in mesoporous silica gel was higher than in microporous structure of zeolite 13X. Considering the above reported study of Chan et al [123], it can be concluded that the composite sorbent preparation procedure can have a significant effect on the obtained results.…”

“…[106,107], activated carbon [30,105] and carbon fibre [108e112] and has received remarkable contributions from the Shanghai Jiao Tong University (China). The second school, with important contributions from the Boreskov Institute of Catalysis (Russia) and its Italian partner, the Institute of Energy Transformation and Accumulation (Italy), uses silica gel [113e120], alumina [119], expanded vermiculite [121] or zeolites as host matrices [122,123].…”

“…Chan et al [122,123] focused on the potential use of composite adsorbents synthesised from zeolite 13X and CaCl 2 for solar adsorption cooling, given that silica gels exhibit lower water uptake than zeolites and lead to relatively low COP. Zeolite 13X was impregnated with 40 wt% CaCl 2 solution and the authors reported that higher CaCl 2 contents lead to a dissolution of the CaCl 2 in the composite during adsorption and thus are not applicable.…”

“…One way to improve adsorbent performance is to impregnate the adsorbent with hygroscopic salt to form a composite adsorbent [9]. Chan [10] studied the effects of calcium ion exchange on the adsorption properties of zeolite 13X and obtained an ideal COP of an adsorbent using the 13X/CaCl 2 -water pair of 0.78, compared with 0.54 for the zeolite 13X-water pairs. 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.…”

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.

“…The zeolite properties used are based on Chan et al (2012) experiment, albeit with different granular sizes. The granular sizes of zeolite used in this simulation are 0.5 mm, 1 mm, and 1.5 mm, and therefore analyzable.…”

Cooling systems in tropical countries consume a large portion of the overall energy usage in a building, especially in tropical climates, where there is an especially high demand on cooling systems throughout the year. This paper presents a simulation of the effect of zeolite adsorbent granular size on a zeolite-water solar adsorption chiller for Universitas Indonesia. The adsorption chiller is being mathematically modeled and calculated numerically, using MATLAB®. The mathematical modeling is based on heat transfer principles inside the system for the water inlet and outlet of the system. The adsorption chiller is based on the most recent chiller developed by Shanghai Jiao Tong University (SJTU). The simulation results generally demonstrated the running characteristics of the chiller under a range of different values of granular size. The average granular sizes used in the simulation ranged from 0.5 mm to 1.5 mm. Furthermore, the simulation results showed in detail that the smaller the average granular size of zeolites, the faster the time needed to reach the maximum hot water temperature and the balance state of chilled water outlet temperature.
