Exergy analyses of heat supply systems for a building cluster with CARNOT

Year 2017, Volume: 20 Issue: 4, 191 - 198, 29.11.2017

Abstract

In this paper, a
model to simulate community heating systems is presented and energy and exergy
analyses are conducted for a district heating system with three different heat
generation alternatives. The alternatives are a gas boiler system, a system assisted
by solar thermal collectors with a seasonal thermal energy storage and a gas
boiler as backup, and a system with geothermal borehole heat exchangers
combined with a heat pump. The heat supply of a building cluster of 11
buildings is dynamically modeled using the MATLAB/Simulink based toolbox
CARNOT. The aim is to match the low exergy heating demand with a low exergy
heat source. To cover an energy demand of 263.7 MWh/a, the geothermal
system needs 174.0 MWh/a of exergy, the solar thermal system 269.2 MWh/a
of exergy and the gas boiler system 324.9 MWh/a. A parameter study of the
solar thermal system shows better results for lower supply temperatures and a
lower heat loss coefficient k, but
the results depend strongly on the chosen storage size. It was found that the
use of fossil fuel could be reduced by 43.8 % for the geothermal system
and by 17.6 % for the solar thermal system compared to the gas boiler
system.
