Abstract. For centuries wind energy is the only natural energy at
man's disposal, and then for nearly a hundred years almost forgotten. One
of the reasons is the wind fluctuation over time with impossible exact
prognosis, in addition to small energy concentration to take into consideration
for big investments. Besides, The wind energy hardly accumulates.
Basically, the wind is a part of the solar energy, but in a consequential
form, which directly gives mechanical work. From the total sun radiant
energy on planet, around 2% transfers to wind energy, of which theoretically
59% can be used. Based on the analyses that are done for our conditions,
the total effective energy that we can be obtained from the wind is defined
for each month. On the basis of these analyses and calculations of the
windwheel power as well as on the basis of the heat needed for heating
and air conditioning, a functional diagram is defined for wind energy application
in the heating and air conditioning system. The possibilities of our planet
on this ground are surely many, but they are not examined enough yet.
Key Words: Wind Energy, Windwheel, Heating, Air-conditioning.
MOGUĆNOSTI PRIMENE ENERGIJE VETRA U SISTEMIMA
GREJANJA I KLIMATIZACIJE
Energija vetra je vekovima jedina prirodna energija u službi čoveka,
a zatim stotinjak godina skoro zanemarena. Jedan od razloga za to je vremensko
kolebanje vetra sa nemogučnošću tačne prognoze, te mala koncentracija
energije s obzirom na velike investicije. Osim toga energija vetra se teško
akumulira. U osnovi vetar je deo sunčeve energije, ali u posledičnom
obliku, koji direktno daje mehanički rad. Od sveukupne dozračene energije
sunca na zemlju, oko 2% se pretvara u energiju vetra, od koje se teoretski
može iskoristiti 59%. Na osnovu analiza koje su uradjene za naše uslove,
za svaki mesec je odredjena ukupna efektivna energija koja se može dobiti
od vetra. Na osnovu ove analize i na osnovu izvedenih proračuna snage
vetrogeneratora i na osnovu analize potrebne toplote za grejanje i klimatizaciju
objekata definisana je funkcionalna šema primene energije vetra u sistemima
grejanja i klimatizacije. Mogućnosti naše zemlje na ovom području
su sigurno znatne, ali nedovoljno istražene.
Ključne reči: energija vetra, vetrogenertor, grejanje, klimatizacija
