“…It was also found that the composite made of the woven braided fabric exhibits better mechanical properties than that of randomly oriented short fibre-reinforced composite. Kumar and Yadav [ 14 ] carried out an experimental investigation on solar-powered composite desiccant cooling system in which the composite desiccant bed heat exchanger was made using iron mesh and jute layer impregnated with calcium chloride solution.…”

Due to the growing environmental awareness, the development of sustainable green composites is in high demand in composite industries, mainly in the automotive, aircraft, construction and marine applications. This work was an attempt to experimentally and numerically investigate the dynamic characteristics of Woven Flax/Bio epoxy laminated composite plates. In addition, the optimisation study on the dynamic behaviours of the Woven Flax/Bio epoxy composite plate is carried out using the response surface methodology (RSM) by consideration of the various parameters like ply orientation, boundary condition and aspect ratio. The elastic constants of the Woven Flax/Bio epoxy composite lamina needed for the numerical simulation are determined experimentally using two methods, i.e., the usual mechanical tests as well as through the impulse excitation of vibration-based approach and made a comparison between them. The numerical analysis on the free vibration characteristics of the composite was carried out using ANSYS, a finite element analysis (FEA) software. The confirmation of the FE model was accomplished by comparing the numerical results with its experimental counterpart. Finally, a comparison was made between the results obtained through the regression equation and finite element analysis.

“…The effectiveness of DEC unit depends on outlet air conditions SCHE. The average energy cooling capacity of SPDAC is 648.2 W. The cooling capacity of the present system (SDAC) is increased by 83.21% as compared to the solar‐powered composite desiccant cooling system by using composite desiccant “CaCl 2 /jute.” 28 The average energy and exergy COP of the SPDAC are 0.45 and 0.35, respectively. Despite the outlet air condition of SPDAC do not lie in the human comfort zone, the results verify that the SPDAC has a good potential to use it for summer air conditioning.…”

“…The average exergy cooling capacity produced by the heat exchanger and SCHE are 195.8 W and 441.5 W, respectively. The present experimental setup have an improvement of 83.21% in average cooling capacity when compared to the solar‐powered composite desiccant cooling system by using composite desiccant “CaCl2/jute.” 28 The temperature of process air has significant effect on adsorption capacity of desiccant material. The pre‐cooling of process air increased the adsorption capacity of SCHE by 15.3%, which is quite remarkable. It is observed that the SPDAC is more effective in winter season, this is because SCHE batter performance in regeneration process.…”

In the present work, solar powered desiccant air conditioning system (SPDAC) is operated for two different modes (a) cooling & dehumidification (b) heating & humidification under summer and winter climatic conditions, respectively. The SPDAC consists of evacuated tube solar water heater, silica gel coated heat exchanger, heat exchanger and direct & indirect evaporative cooling unit. The performance of the SPDAC is evaluated in terms of energy & exergy cooling/heating capacity, COP and economic & exergoeconomic feasibility. The energy & exergy cooling capacity and energy & exergy COP of the SPDAC during cooling and dehumidification modes are 648.2 W & 254.1 W, and 0.45 & 0.35, respectively. Whereas, the energy & exergy cooling capacity and energy & exergy COP of the SPDAC during heating and humidi-fication mode are 847.4 W, 427.9 W, 0.87, and 0.45, respectively. The economic and exergoeconomic analysis indicates the reliability of the SPDAC system and also proves to be efficient in terms of payback period (43.8 months). The outcomes demonstrate that the SPDAC is more compelling in heating & humidification mode under winter climatic conditions. The overall results of the system confirmed that the use of silica gel coated heat exchanger is practicable to run the system in both seasons.

In the present study, a novel Trombe wall-assisted desiccant wheel system is modeled, in which the trombe wall is divided into three equal parts and provides the heat required for regeneration of the desiccant wheel. Separate mathematical models have been proposed for di erent components of the system such as desiccant wheel and Trombe wall. The mathematical models of di erent parts have been assembled. E ects of the geometrical parameters of the Trombe wall on the regeneration temperature of the desiccant wheel have been investigated based on the integrated model. The results of the present study for some special cases have been compared with results available in open literature. The optimal surface area of the Trombe wall has been extracted according to the parameters of the desiccant wheel. Results show that the solar energy received by the Trombe wall is 600-740 W/m 2 (1 May-15 August) in the warm and humid climate of Gilan (Iran), the temperature of the wall surface is obtained 77-86 C, and the outlet temperature of regeneration air stream from Trombe wall is obtained 60-70 C; however, the output humidity of the desiccant wheel is reduced from 23 gw/kga to 10-12 gw/kga in the studied region (Gilan, Iran).
