摘要：The article considers the possibility to use different types of polymer thermal store materials for regenerative heat exchangers in local ventilation systems. The research provides evidence for the benefits of the replacement of the most commonly used metal and non-metallic materials in the manufacture of the regenerator honeycomb matrix. It does so by presenting the results of calculations and comparative analysis of the influence of thermo-physical properties of a wide range of polymers on the thermal efficiency of a fixed counter-flow regenerator operating with humid air. In order to evaluate the efficiency, we have used a numerical solution of the system of mathematical physics equations describing the process in the regenerator. The system also includes an appropriate CFD model of the evaporation-condensation phase change process.
