Possibility of Thermal Storage System Use with Different Accumulating Material in SPbSTU

Abstract

In this article the possibility of heat accumulator use in one of the buildings of SPBSTU was analyzed. The use of this accumulator could lower the hot water demand. To complete the goal it was assumed that there is an additional café with defined working hours. Different kinds of heat collecting materials were studied: water, red brick, concrete and granite. Depending on charging time of the heat accumulator, the results of the heat gaining abilities of different materials were made. As a result it was calculated that single-phased accumulating materials should not be used as heat collectors in public buildings.
