- W9971326 abstract "The developed earlier mathematical model is applied for calculations of processes in the hydride heat pump (HHP) intended for increase or reduction of a level of temperature. The model set of equations actuates non-stationary one-dimensional equations of thermal balance in hydride sorbers with allowance for of thermal effects at an absorption/desorption of hydrogen. In computer calculations the experimental data on equilibrium isotherms in systems a metal alloy hydrogen are used. As a high-temperature hydride ZrCrFe1.2, low-temperature hydride LaNi5 is used. In calculations the time cyclogramme of activity a HHP is determined: distribution of temperature of design elements on a radius of a cylindrical hydride bed, contents of hydrogen in sorbers, pressure of hydrogen, energy and thermal power. The alternative calculations are carried out for an actual module of the heat pump. The research of influence of main parameters of a mode of the heat pump (hydrogen pressure of charge, temperatures and consumptions of the heat-carrier, time of a cycle) on it the power characteristics is carried out. Is shown that at the temperature of heat source 80–95°C can be obtained an overheated water at the temperature of 110°C and the cooled water with temperature in region 0°C. It is shown that the computational data satisfactorily coincide experimental results. It is established that the developed model the HHP is possible to use for qualitative and quantitative study of influence of various parameters on operation.Key wordsHydridehydrogenheat pumpsimulationcalculationexperiment" @default.
