“…Several other analytical studies on impregnation of calcium chloride on various host matrices have been done for heat storage purpose: iron silicate [141], silica gel [98,113,139,140,145,146], active carbon [145], bentonite [99,144], MCM-41 [128]. However, upscaling experiments to lab-scale experiments are rare because of less reaction of rate or less cycle stability.…”

“…Water was pumped from the reservoir and water coming from the heat exchanger (11) was directed into drains. The water container (7) was placed on the weight scale (8), which enabled precise measuring of quantity of inlet water in the evaporator. For the process of desorption, instantaneous water heater (12) was installed in order to enable hot water.…”

Abstract:The main goal of this research was to develop the adsorption thermal storage device for domestic heating system charged by solar collectors and to indicate a new way of storing energy. Main characteristic of the storage system is to retain the energy for a longer period (seasonal storage), as long as the adsorbent and adsorbat are separated. In this research the influence of several parameters on the adsorption heat storage system is performed such as: the quantity of the stored heat, the inlet and the outlet water temperatures, the water mass flow and the saturation of the adsorbent. Adsorbent silica gel HX-13 (sodium aluminosilicate Na2O Al2O3 * 2SiO2) in the form of granule was used.According to the results the conclusion can be made that the low adsorption heat storage is a consequence of low hydrophilic characteristic of the used adsorbent and therefore additional research is needed.

“…Unfortunately, pure salt hydrates lose their performance after the formation of crystalline hydrates; most salt hydrates melt congruently with the formation of lower hydrates, making the process irreversible and leading to a continuous decrease in their storage efficiency [21]. In order to avoid the problems associated with crystallization (phase segregation and supercooling), while improving the water vapor sorption capacity of the porous material, hygroscopic salts are deposited onto high surface porous materials [7,[22][23][24][25].…”

CaCl 2 -containing composites have been prepared by depositing the hydrated salt (by incipient wetness impregnation) on three different silica-aluminas with various Si/Al ratios. The surface area and porosity of all the samples were determined by N 2 -adsorption at -196°C, and their water sorption properties were investigated by thermogravimetry linked to differential scanning calorimetry (TG-DSC) in order to determine the quantity of adsorbed/desorbed water and the related heats. The heat released and the quantity of adsorbed water were found to depend on parameters such as the silica-alumina pore diameters, the Si/Al ratio, and the presence of accessible CaCl 2 active phase. The short-term stability of both supports and composites has been also checked by performing successive hydration-dehydration cycles. The sample with the lower Si/Al ratio provided the highest heat per surface area of material, and the heat released per mol of water increased with the amount of Al 2 O 3 present in the samples. The deposition of CaCl 2 positively acted on the quantity of heat released during the water sorption, and the composite with the higher alumina content (75 mass% Al) showed the largest heat released per m 2 of material (2.4 J m -2 ) compared to those containing 25 and 13 mass% Al (1.4 and 1.2 J m -2 , respectively).
