Özet:

Energy storage has become important due to an energy crisis that has reached serious dimensions as a result of rapid and uncontrolled consumption of fossil-based energy resources which are available on earth with increasing industrialization. Energy can be stored as mechanical, chemical, biological, magnetic and thermal energy. Thermal energy storage is one of the important technologies which takes place for the conservation and efficient use of energy. A heating system was designed for low-temperature heat generation, storing low-temperature heat and supplying hot water needed for domestic use and certain experiments were carried out. In this study, the experimental outcomes (results) of four sensible heat storage materials (water, glycerol, synthetic oil and alumina) which took place separately in a thermal energy storage unit were given during discharge periods when the energy source could not be sufficient for the energy need. For this purpose, at a tap flow rate of 1.2 l/min, the changes in the heat amounts drawn out of heat storage unit, heat losses from the heat storage unit to the ambient air, the changes of the domestic water outlet temperatures, central temperatures in the heat storage unit were evaluated comparatively.
