Korinchevska T. Thermophysical properties of heat storage materials with phase change based on organic compounds

The thesis is dedicate to research of thermophysical properties of phase change materials based on organic compounds for use as working medium of heat storage systems. The organic compositions with phase change of first kind are considered for heat storage systems. These compositions are used in foundry work as model mixtures. The results of researches of their thermophysical properties and operational characteristics are presented. А mixture of 85% paraffin and 15% brown-coal wax is recommended for further use as a working medium of heat storage systems. The kinetics of heat storage by this material is experimentally and theoretically investigated. On the basis of the obtained results, the design of heat storage system is developed for space heating and the means of application of heat storage materials with phase change are offered in technological schemes of drying of thermolabile raw materials.
