In this study a methodology is developed for the design of a packed bed reactor to be used in a Chemical Heat Pump (CHP). Adsorption and desorption of ethanol on active carbon packing in the reactor are investigated. Depending on the cycle, i.e. adsorption or desorption, cooling or heating of the reactor material is modeled through transient energy equation. The parameters associated with the vapor-carbon adsorption kinetics are experimentally determined. Then spatial distribution of temperature and adsorbed vapor amount are obtained with respect to time in adsorption desorption cycles. These profiles are used to predict heating or cooling powers and COP for different adsorbent bed geometries and adsorption/desorption cycle times. Strong effect of heat transfer resistance of the packing, hence reactor size, on the system performance is observed.

Mathematical and computational modelling of chemical heat pumps Güneş, Talha; Uludağ, Yusuf; Karakaş, Gürkan; Department of Chemical Engineering (2018) Chemical heat pumps are valuable alternatives to conventional heat pumps when the aim is re-utilizing waste energy that is created from natural or industrial sources. In this study, kinetic data of an activated carbon – ethanol adsorption reactor is modeled and properly implemented into COMSOL Multiphysics software, and the geometry is modified for higher rate of heat transfer with the aim of gaining more performance from the system. On top of that, various cycle times are studied for gaining optimal coolin...
Exergetic optimization of generated electric power split in a heat pump coupled poly-generation system Kilkis, Birol I.; Kılkış, Şiir (2007-01-01) This study analyzes environmental, energy, and economical benefits of a ground source heat pump, coupled poly-generation system by incorporating exergy into the energy efficiency analysis. Two additional terms, namely the rational exergy efficiency and the coefficient of performance were introduced to the primary energy savings equation in the European Union Directive 2004/8/EC. Based on the new equation, an optimization algorithm was developed, which can quantify the environmental, energy and economy benef...
Numerical methodology for feasibility analysis of ground source heat pumps Gamage, Kumudu Janani; Uzgören, Eray; Sustainable Environment and Energy Systems (2014-8) Ground source heat pump (GSHP) systems provide an alternative energy source for residential and commercial space heating and cooling applications by utilizing the favorable temperature profile at a certain depth under the ground surface. GSHP’s aftereffects on the ground temperature profile need to be considered for estimating the economical breakeven point. The present study develops a new semi-analytical model to analyze the short term response of the ground heat exchangers by accounting the depth depende...
Mathematical modeling of adsorption/desorption systems for chemical heat pumps Yurtsever, Ahmet Onur; Uludağ, Yusuf; Karakaş, Gürkan; Department of Chemical Engineering (2011) Despite their limited commercial applications, chemical heat pumps (CHP) have been considered as an important alternative to conventional heating and cooling technologies. In this study, the adsorption-desorption of ethanol over activated carbon was applied on the CHP reactor. The ethanol vapor - activated carbon adsorption rate was determined at 30, 60, 90 and 120° experimentally by using Intelligent Gravimetric Analyzer C(IGA). The experimental adsorption data were used on the transient modeling of reacto...
Modeling and sensitivity analysis of high temperature PEM fuel cells by using Comsol Multiphysics Sezgin, Berna; Caglayan, Dilara Gulcin; DEVRİM, YILSER; Steenberg, Thomas; Eroğlu, İnci (2016-06-22) The objective of this study is to observe the effect of the critical design parameters, velocities of inlet gases (hydrogen and air) and the conductivity of polymer membrane, on the performance of a high temperature PEM fuel cell. A consistent and systematic mathematical model is developed in order to study the effect of these parameters. The model is applied to an isothermal, steady state, three-dimensional PEM fuel cell in order to observe concentration profiles, current density profiles and polarization ...
