Abstract:
Stalan razvoj svetske ekonomije uticao je na smanjenje rezervi fosilnih goriva, a samim tim i na porast njihove cene. U cilju pronalaženja rešenja ovog problema i radi zaštite životne sredine, neophodno je koristiti nove tehnologije za primenu obnovljivih izvora energije. Značajnu ulogu u prelasku na obnovljive izvore energije ima toplotna pumpa, koja obezbeđuje efikasnije iskorišćenje obnovljivih izvora energije, kao i otpadne toplote. U zavisnosti od namene, uslova na mestu ugradnje i mogućnostima iskorišćenja energije iz okoline, u praksi se upotrebljavaju toplotne pumpe prilagođene raznim kombinacijama prenosa toplote kao što su vazduh-voda, voda-voda, zemlja-voda, vazduh-vazduh, voda-vazduh i zemlja-vazduh. Kako toplotna pumpa koristi električnu energiju za svoj rad, kombinacija toplotne pumpe sa fotonaponskim ćelijama, vetrogeneratorima ili nekim drugim oblikom obnovljivih izvora energije za dobijanje električne energije može dodatno da doprinese energetskoj efikasnosti i nezavisnosti. Radi procene efikasnosti toplotne pumpe, neophodno je pratiti njen godišnji radni učinak, tj. razliku proizvedene toplotne energije i utrošene električne (u proseku odnos utrošene struje i dobijene toplote iznosi 1:4 ili 1:5). THE INCREASE OF ENERGY EFFICIENCY USING HEAT PUMPS The rapid development of the world economy has affected the reduction of fossil fuel reserves, and therefore, the increase of their prices. In order to find solutions of this problem and to protect the environment, it is necessary to use novel technologies for therenewable energy sources application. The heat pump plays an important role in the transition to renewable energy, providings more efficient use of renewable energy and waste heat. Depending on the application, conditions on site and the possibilities of energy utilization from the environment, the use of heat pumps can be adapted to various combinations of heat transfer, such as air-water, water-water, ground-water, air-air, air-water and surface-air. Since the heat pump is using the electricity for its work, the combination of heat pumps with photovoltaic cells, wind turbines, or other form of renewable energy for electricity generation can further contribute to energy efficiency and independence. In order to assess the efficiency of the heat pump, it is necessary to monitor its annual performance, the difference between produced thermal energy and consumed electricity (an average ratio of consumed electricity and obtained heat obtained is 1: 4 or 1: 5).
