District heat and cold supply Daljinska oskrba s toploto in hladom

- odvečna toplota - surplus heat

- OVE (geotermalna) - RES (geothermal)

- odpadki - waste

- plin - gas

- odvečna toplota - surplus heat

- OVE (geotermalna) - RES (geothermal)

- električna energija - electricity

- premog - coal

Prednosti daljinskega ogrevanja in hlajenja Advantages of district heating and cooling

Za uporabnike For users - potrebno malo prostora v objektu - need for less space in building - nizka investicija, relativno nizka cena ogrevanja in hlajenja, poceni vzdrževanje - low investment, energy and maintain cost of heating and cooling - ni potrebe po dodatni opremi (kotel, hladilnik, hranilnik, dimnik, deponija goriva) - no need for additional equipment (boiler, refrig., acumulator, chimny, landfill) - ni nevarnosti požara, eksplozije, nevarnih snovi - no danger of fire, explosion, danger substances - večje udobje (avtomatizirano in neprekinjeno delovanje, ni skrbi za energent) - higher comfort (automatic and continous opearation, no concern on fuel

Energetska učinkovitost in varovanje okolja Energy efficiency and environment protection - višja vrednost faktorja primarne energije FPE - higher FPE factor - višji energijski izkoristki - higher energy efficiency - nižje emisije - lower emisions
