Possibilities of introducing a district cooling system in LjubljanaKitanovski, Andrej ...V ljubljanskem sistemu daljinskega ogrevanja prihaja v poletnem obdobju obratovanja do bistveno zmanjšanega odjema toplotne energije. Pri določeni spodnji meji toplotnega odjema se pojavi dilema, ali ... še obratovati s sočasno proizvodnjo električne in toplotne energije ali preiti na ločeno proizvodnjo toplote v vršni kotlovnici. Rešitev se kaže v povečevanju toplotnega odjema v poletnem obdobju z uvedbo sistema daljinskega hlajenja. Raziskava odjemalcev daljinskega ogrevanja v Ljubljani kaže, da v Ljubljani obstaja potencial okrog 50 MW povečanja toplotne moči na račun hlajenja. Zaradi obratovalnih posebnosti ljubljanskega sistema daljinskega ogrevanja pride v poštev decentraliziran sistem daljinskega hlajenja z absorpcijskimi hladilniki, gnanimi z vročo vodo ali paro. Takšni sistemi so lahko konkurenčni kompresorskim hladilnim sistemom, če so integrirani v sistem sočasne proizvodnje električne in toplotne energije, ter ob ugodnem razmerju cen električne in toplotne energije. Iz primerjave celotnih stroškov v življenjski dobi kompresorskega in absorpcijskega hladilnega sistema, hladilne moči 1 MW sledi, da bi znašala konkurenčna cena toplote ob upoštevanju aktualne cene električne energije 4.26SIT/kWh.Source: Proceedings (Str.
