The Сhoice of Shape and Volume Calculation of Seasonal Heat Accumulator


Abstract. One of the thermal energy storage technologies during the warm season, its preservation and future use is to create seasonal heat accumulators. As a source of heat during the warm period of the year for charging the seasonal heat storage a system of solar collectors is often used. For such systems (solar collectors + seasonal heat accumulator), the organized seasonal heat accumulators should be used, which are designed for a certain amount of heat. In this article there is a comparison of the influence of the placement of the heat accumulator to the choice of its shape. The method of calculation of the heat accumulator volume is proposed, taking into account the work of solar collector system throughout the year. Influence of work of year-round system of solar collectors on reduction of volume of the thermal accumulator is considered. Accomplished plotting the daily thermal load on the heating system and hot water + heat comes from solar collectors system.


Key words: concrete heat accumulator; combined heat accumulator; seasonal heat accumulator; shape of seasonal heat accumulator; calculation of the volume of seasonal heat storage
