“…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.…”

“…The current state in the field of adsorptive heat transformation (AHT) cannot be considered as wholly satisfactory, due to inappropriate thermodynamic properties of adsorbent materials [3], therefore studies tends to improve materials. Developed composite sorbents made from active salts and porous materials showed improved sorption storage capacity when compared to water-based energy storage due to its high energy density [11][12][13]. Exergy analysis performed by Abedin et al [14] showed that thermo-chemical sorption energy storage system may be as efficient as and even more stable than other types of thermal energy storage system.…”

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.

“…Solid sorption heat pumps do not need any CFC, HCFC or HFC refrigerant; most of them make use of natural refrigerants. Examples of solid sorbent vapour combinations are silica gel/water [10][11][12][13], SWS/water [13][14][15], zeolite/water [16], and NH 3 /carbon [17][18][19]. This technology does not have moving parts, is therefore silent, and does not require much servicing.…”

A low-grade waste heat driven solid/vapour adsorption chiller has been successfully designed and tested. A simple model was developed to aid the design and predict the performances. The system comprised two identical sorption reactors operating out of phase in order to ensure continuous cold production. One sorption reactor consisted of six commercially available automotive plate/fin heat exchangers in which silica gel grains were accommodated between the fins. The system was tested as to the power delivered at 12 °C and the power density. The average cooling power was 3.6 kW. This is only 72% of the design value and can be largely attributed to the lower heat transfer fluid flow rate through the sorbent reactor. The thermal efficiency, COP, was 0.62 and the power density was 17 kW/m 3 for the system as a whole. Higher power densities are possible. At present, the adsorption chiller is integrated in a prototype trigeneration system, which is tested at CRF's Eco-building in Turin. Keywords

“…The COP for cooling was predicted to be approximately 1.6. Aristov et al [2] studied the adsorbent performance. They reported that composite bases of various host micro-and mesoporous silica gel matrices were able to absorb water when they were impregnated with calcium chloride (CaCl 2 ) and lithium bromide (LiBr) salts.…”

Performance Analysis of a Double-effect Adsorption Refrigeration Cycle with a Silica Gel/Water Working Pair

et al. 2010

A numerical investigation of the double-effect adsorption refrigeration cycle is examined in this manuscript. The proposed cycle is based on the cascading adsorption cycle, where condensation heat that is produced in the top cycle is utilized as the driving heat source for the bottom cycle. The results show that the double-effect cycle produces a higher coefficient of performance (COP) as compared to that of the conventional single-stage cycle for driving temperatures between 100 °C and 150 °C in which the average cycle chilled water temperature is fixed at 9 °C . Moreover, the COP of the double-effect cycle is more than twice that of the single-stage cycle when the temperature reaches 130 °C . It is also observed that the adsorbent mass ratio of the high temperature cycle (HTC) to the low temperature cycle (LTC) affects the performance of the double-effect adsorption refrigeration cycle.
