A single effect LiBr–H2O absorption refrigeration system coupled with a solar collector and storage tank was studied to develop an assessment tool using the built-in App Designer in MATLAB®. The model is developed balances of mass, energy, species conservation components cooling system, taking into account external streams through temperature pressure drop. whole energy harvesting arrangement, ...

While many proteins are recognized to undergo folding via intermediate(s), the heterogeneity of equilibrium folding intermediate(s) along the folding pathway is less understood. In our present study, FTIR spectroscopy, far- and near-UV circular dichroism (CD), ANS and tryptophan fluorescence, near IR absorbance spectroscopy and dynamic light scattering (DLS) were used to study the structural an...

Reaction of readily available N-benzylbenzamide (I) with a slight excess of BuLi produces a deep blue dianion. Under suitable conditions (THF, -40*(2), 1 may be used as a stoichiometric reagent to titrate n-BuLl, s-BuLi, and t-BuLi with good precision. Less reactive alkyllithiums (MeLi and MeLi, LiBr), aryllithiums, and LDA may be titrated at higher temperatures ( 20 to 0°C). Titres are compara...

An analytical analysis has been presented to evaluate the performance of a solar-assisted va-pour absorption cooling system with flat-plate absorber plate. The lithium–bromide water cycle is used obsstain effect. parameters, namely plate efficiency, collector efficiency factor, heat removal etc. have deter-mined variation fluid inlet temperature. coefficient perfor-mance (COP), COP, refrigerati...

A parametric study has been carried out based on advanced exergy assessment for a parallel double-effect LiBr–water absorption chiller. The method provides the real potential of equipment improvement in system by recognizing avoidable irreversibilities. sensitivity analysis various parts destruction (endogenous avoidable, endogenous unavoidable, exogenous and unavoidable) components overall per...

Due to the merits of energy saving and environmental protection, the absorption chiller (AC) has attracted a lot of attention, and previous studies only concentrated on the dynamic response of the AC under a single working condition. However, the working conditions are usually variable, and the dynamic performance under different working conditions is beneficial for the adjustment of AC and the...
