САЖЕТАК / ABSTRACT:

S obzirom na sve intenzivnije i očiglednije promene klime i porast globalne temperature, a istovremeno i na rast svetske populacije i ubrzane procese migracije stanovništva iz ruralnih u urbane sredine, potrošnja energije za hlađenje stambenog i poslovnog prostora je u stalnom porastu, sa tendencijom da će se i dalje ubrzano uvećavati. Sa druge strane, s obzirom na danas opšteprihvaćenu teoriju da je porast globalne temperature prouzrokovan povećanim antropogenim emisijama gasova sa efektom staklene bašte, kao jedan od ključnih načina za usporavanje njenog porasta ustanovljen je princip neophodnosti prelaska sa fosilnih goriva na korišćenje obnovljivih izvora energije (OIE). U tom smislu, povezujući porast potreba za energijom za hlađenje i prelazak na korišćenje OIE, kao optimalno rešenje nameće se korišćenje sunčeve energije za potrebe hlađenja. U prilog tome idu činjenice da je, među svim vrstama OIE, korišćenje sunčeve energije najperspektivnije jer je neiscrpno, svuda dostupno i gotovo bez efekata zagađivanja okoline. Pored toga, potrebe za hlađenjem su najveće upravo kada i sunčevo zračenje dostiže svoj maksimum, a i potreba za hlađenjem je veća u oblastima sa toplijom klimom. Jedna od mogućih tehnologija koje omogućavaju ostvarivanje procesa hlađenja pomoću sunčeve energije predstavljaju apsorpcioni rashladni sistemi. Usled razvijanja sve efikasnijih sistema za prikupljanje i skladištenje sunčeve energije, postoji mnogo razloga za sve veće istraživanje u oblasti apsorpcionih rashladnih sistema. Pored objašnjenja principa rada i sagledavanja energetskih tokova, te određivanja energetskih stepena korisnosti ovih sistema u ovom radu su predstavljeni do sada razvijeni matematički modeli sistema za hlađenje pokretanih energijom sunčevog zračenja i izvršena njihova termodinamička analiza.
