Performance assessment of an integrated PV/T and triple effect cooling system for hydrogen and cooling production
(2011-08)
In this paper we study an integrated PV/T absorption system for cooling and hydrogen production based on U.A.E weather data. Effect of average solar radiation for different months, operating time of the electrolyzer, air ...
Analysis of Maisotsenko open gas turbine power cycle with a detailed air saturator model
(Elsevier, 2015-07)
With ever increasing cost of fossil fuels and natural gas, the improvement in gas turbine power cycle efficiency is needed due to the tremendous savings in fuel consumption. Water/steam injection is considered as one of ...
An Experimental Investigation of a Cold Thermal Energy Storage System
(2013-02)
This research work investigates the heat transfer characteristics of a direct contact heat exchanger. A cold two phase refrigerant R134a is injected into water stored in an evaporator to exchange directly heat with the ...
Performance Assessment of a Liquid-Phase-Separation Refrigeration Cycle
(Wiley, 2012-10)
Absorption refrigeration cycles are alternatives to conventional vapor-compression cycles in which the energy required for refrigeration is provided by heat instead of mechanical work. In this paper, a novel refrigeration ...
Economics of hydrogen production and liquefaction by geothermal energy
(2012-01)
Seven models are considered for the production and liquefaction of hydrogen by geothermal energy. In these models, we use electrolysis and high-temperature steam electrolysis processes for hydrogen production, a binary ...
Thermodynamic analyses of an integrated PEMFC-TEARS-geothermal system for sustainable buildings
(2012-01)
In this paper we undertake a comprehensive study to meet the building heating/cooling and power demand through a sustainable operation. We integrated polymer electrolyte membrane fuel cell (PEMFC) system and triple effect ...
Performance analysis and evaluation of a triple-effect ammonia-water absorption-refrigeration system
(Wiley, 2013-01)
In this paper, a comprehensive thermodynamic analysis of the triple-effect absorption-refrigeration system using ammonia-water solution is carried out in order to investigate the effect of different operating conditions ...
Performance analysis of a new designed PEM fuel cell
(Wiley, 2012-09)
In this paper, a new design for the flow channels is presented, and a parametric study of the proton exchange membrane (PEM) fuel cell is conducted in order to investigate the effect of the new flow channels, as well as ...
Performance Evaluation of a Thermal Energy Storage
(2013-02)
The direct contact heat transfer technique gives better heat transfer rates. In this paper, the operation of a simple system was simulated under different operating conditions. During the charging mode of the operation, ...
Performance characteristics of an ammonia-water absorption heat pump system
(2013-11)
The influences of the performance parameters and the heat transfer characteristics of the absorption heat pump using ammonia-water mixture are theoretically carried out. There is a pronounced effect of the ammonia concentration ...
