Sažetak
Realization of the 100% renewable energy systems cannot be achieved without large energy storages. Energy storage markets are dominated by electric and heat storages, while heat storages can further be divided on sensible heat and latent heat storages. Focus of this paper is on high-temperature latent heat storages, also known as Phase Change Materials (PCM) storages. High-temperature PCM is well known technology, which has not seen wider use due to its shortcomings (corrosion, low thermal conductivity, price, etc.). Nevertheless, great potential of PCM will unquestionably lead to its wider integration in energy systems. Recent researches have shown significant improvement in direction of the high-temperature PCM usage inside thermal solar power, combined heat and power systems and process industry, while new incentive in thermal storage for solar thermal plants around globe can be seen in recently. While simulation models for low temperature latent heat storages have been extensively developed in the last few years, number of high temperature PCM models is still limited. In this paper mathematical model of heat transfer and phase change inside of PCM is proposed and verified with available experimental data. Importance of convection as dominant heat transfer mechanism during phase change is emphasized and modelled in detail. Improved model accuracy allows for more precise storage design, long scale simulation of whole system and cost effective heat exchanger design. Furthermore, presented model will provide basis for heat storage and heat exchanger design optimization.
