PROGRAM TOOLKIT FOR MODELING AND OPTIMIZATION OF ADSORPTION AND CHEMICAL HEAT PUMPS AND REFRIGERATORS
Краткое описание
A set of programs for numerical modeling and optimization of adsorption and chemical heat pumps and refrigerators has been developed. The modeling is based on one-dimensional (in the radial direction) consideration of dynamic adsorption or chemical reversible reactions in a cylindrical reactor filled with adsorbent. The program toolkit allows investigation of various heat-conversion devices designed as a combination of one or several reactors with condensers and evaporators. The programs have options for varying reactor parameters, thermal reservoir temperatures, resistance of control valves connecting the reactors, as well as time of their opening and closing. The graphical representation of time history for mean temperature and sorbate content in the reactors is shown in the program window as well as the effective Clausius–Clapeyron-diagram dynamics of working medium. As a result of modeling, the programs calculate main characteristics of thermal energy conversion such as coefficient of perfomance (COP), specific cool (and heat) production, SHP (SCP), and the maximal temperature difference between the heat carrier and adsorbent during the process. The developed approach and algorithms were validated by comparison of numerical results with experimental data.
