The present work investigates the thermodynamic optimality of a double-effect vapor absorption refrigeration system (VARS) driven by blowdown heat 210 MW thermal power plant at Badarpur using response surface methodology (RSM). RSM helps to develop relation amongst decision variables and second law efficiency vi se cond-order nonlinear polynomial regression equation. In addition, analysis varia...

The aim of this work is to bring forward a new style heat exchanger about hollow fiber membrane module, and to analyze the performance which can expectantly be applied in the lithium bromide absorption refrigeration system. Polyvinylidene fluoride hollow fiber membrane module was adopted as the new style solution heat exchanger, hot feed solution from the generator flowed into the lumen side of...

This study aims to investigate the applicability of vacuum membrane distillation for concentrating aqueous lithium bromide solution, and to analyze the feasibility of applying vacuum membrane distillation process to the absorption refrigeration system. Hydrophobic polyvinylidene fluoride (PVDF) was adopted as the membrane material, and was made into hollow fiber membrane module. Commercial aque...

Abstract Global warming is raising the ambient temperature and thus resulting in increased air conditioning requirements. The increase power requirements of systems, turn, burdens electricity needs more generation further adds to global warming. In such situations, availability solar energy its utilization for systems appears a potential solution certain extent. This paper deals with thermodyna...

In this study, a new metal hydride heat pump system driven by an electrochemical compressor was proposed.The system uses the electrochemical compressor to generate absorption heating and desorption cooling in two identical LaNi5 reactors operating at different pressure levels. A thermodynamic model was developed to predict the system performance in terms of various parameters. Modeling shows EC...

Capacity and efficiency of any refrigerating system diminish rapidly as the difference between the evaporating and condensing temperature is increased by reduction in the evaporator temperature. The single stage vapour compression refrigeration system is limited to an evaporator temperature of -40 C. Below temperature of -40 C the either cascade refrigeration system or multi stage vapour compre...
