Centralni niskotemperaturni grejni sistem sa toplotnom pumpom i zemljom kao izvorom energije
Low temperature hydronic heating system with radiators and geothermal ground source heat pump
Apstrakt
Upotreba grejnog sistema s toplotnom pumpom i zemljom kao izvorom energije bez obzira na relativno nisku temperaturu raspoloživog "izvora" geotermalne energije (temperatura vode ili tla ne mora biti viša od 12°C), omogućava da se 50-80% energije potrebne za grejanje preuzme od zemlje, a da se ostatak nadomeštava električnom energijom. Ovaj udeo geotermalne energije, u ukupnoj energiji potrebnoj za grejanje, zavisi pre svega od sistema njene dalje raspodele (radijatorski sistem, sistem grejanja pomoću fancoil-a ili zidno i podno grejanje), a tek potom i od temperature vode, odnosno tla. U radu je data uporedna analiza termičke efikasnosti dva sistema centarlnog grejanja sa radijatorima kao grejnim telima, visokotemperturnog kotlovskog sistema grejanja (90°C/70°C) i niskotemperaturnog sistema sa toplotnom pumpom i zemljom kao izvorom energije (65°C/55°C, 55°C/45°C ili 50°C/45°C).
The use of a system with a geothermal ground source heat pump, regardless of the relatively low temperature of the available source of geothermal energy (water or ground temperature does not need to exceed 12°C), allows 50-80% of the energy required for heating to be taken from the ground, while the remaining amount is provided by electrical energy. This share of geothermal energy, in the total energy required for heating, primarily depends on the system of its further distribution (radiator system, fan coil heating system or wall and floor heating), and secondarily on water and ground temperature. The paper deals with the comparative analysis of thermal efficiency of two water central-heating systems with radiators, a conventional high-temperature heating system with a boiler (90°C/70°C) and a low-temperature heating system with a geothermal ground source heat pump ( 65°C/55°C, 55°C/45°C or 50°C/45°C).
