UTILISATION OF THE TWO-COMPONENT SYSTEM WITH PHASE CHANGE IN ONE OF THE COMPONENTS AS THE HEAT SOURCE FOR A HEAT PUMP

摘要

The possibility of utilisation of the two-component system composed of water and an inclusion of any shape, for example of thin metal fin, with water-ice phase change as the heat source for a heat pump has been considered. Existence of the additional object or set of objects (metal or heat insulator) in the phase change area can significantly change the solidification process in comparison to classical Stefan problem. Utilisation of the two-component heat storage gives the possibility of some regulation. Intensification or reduction of a speed of the solidification process is available. The storage can be applied to maximise or minimise the amount of the energy accumulated in the system and used by the heat pump.
