Comparison of Constructions of Heat Accumulators with a Solid Heat Storage Material and Combined HeatStorage Material


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 seasonal heat storage often use system of solar collectors. For such systems (solar collectors + seasonal heat accumulator) should be used organized seasonal heat accumulators, which are designed for a certain amount of heat. The article compares the constructions of concrete thermal storage and combined heat accumulators with liquid and solid heat accumulating material. Use of physical and mathematical model of the accumulation of heat energy from solar collectors, under which in Solidworks software package made a qualitative assessment of the processes for the different constructions of heat accumulators, taking into accountthe fact that heat accumulator is under the house.


Key words: concrete heat accumulator; combined heat accumulator; seasonal heat accumulation; seasonal heat accumulator; seasonal battery design
