Thermodynamic and economic analysis of different fuels usage on example of residential building

Abstract: На основу података Енергетског биланаса Републике Србије за 2017. годину, потрошња финалне енергије је процењена на 8429 Mtoe, од чега је 48% укупне потрошње у сектору домаћинства, пољопривреда и јавно-комуналне делатности. У укупној структури коришћења финалне енргије, обновљиви извори енергије (само геотермална енергија и биомаса заједно) учествују са 12%. Осим квантитативне (енергијске) анализе, за потпуно разумевање свих важних аспеката коришћења енергије и успостављања одговарајуће енергетске политике, по… Show more

“…In the case when the radiator heating in the building is an internal subsystem of the GWHP system, ηex,p has a value of 0,088. When it comes to seasonal values of the total exergy efficiency for systems that use conventional energy sources for heating (coal, gas, electricity), they are lower than 0,05 [5], i.e. they have lower values than the GWHP system.…”

“…Their results showed that the best heating system is a heat pump connected to the domestic heat network. Gojak and Bajc [5] also came to the conclusion that the use of the heat pumps is a much better choice for the building heating needs, than the use of high-quality energy sources. This is the result of an exergy analysis of various energy sources use (electricity, natural gas, district heating, coal and renewable energy sources) for the needs of building heating and sanitary hot water preparation.…”

“…The air temperature in observed building is maintained at a temperature of 20 O C (T i = 293K) while the average outside air temperature for each month during the heating season is T o , and values for Belgrade can be found in reference [19]. The exergy demand for maintaining the inside air temperature, i Ex , is given by equation [21][22][23]…”
