Da li ste svesni koliko se elektri\u010dne i toplotne energije rasipa? Glavni uzro\u010dnici su pre svega lo\u0161a termo izolacija<\/strong>, ali i kori\u0161\u0107enje neefikasnih sistema za grejanje i hla\u0111enje. Upravo zbog toga se poslednjih godina poklanja posebna pa\u017enja razvoju tehnologije koja \u0107e koristiti manje elektri\u010dne energija, a biti efikasnija.<\/p>\n

Toplotne pumpe su jedan od ovih izuma koji je doveo do velike promene u na\u010dinu grejanja: uz pomo\u0107 obnovljivih izvora energije mo\u017eete da se grejete ili hladite<\/strong>! Pri tome, ovakve pumpe zahtevaju malu potro\u0161nju elektri\u010dne energije.<\/p>\n

\u0160ta su toplotne pumpe <\/strong><\/h2>\n

Toplotne pumpe su savremeni ure\u0111aji koji za grejanje i hla\u0111enje prostorija i vode koriste energiju vode, vazduha ili zemlje. Ovi sistemi su veoma ekonomi\u010dni i isplativi jer zahtevaju za rad mali uto\u0161ak elektri\u010dne energije.<\/p>\n

Dodatno, za razliku od ve\u0107ine sli\u010dnih sistema, toplotne pumpe nemaju nikakav negativan uticaj na \u017eivotnu sredinu.\"\"<\/p>\n

Ove pumpe<\/strong> mogu biti dovoljne za \u010dak 80 % energetskih zahteva nekog objekta. Jedino je neophodno oko 20 % elektri\u010dne energije ulo\u017eiti kako bi toplotne pumpe mogle da rade. Pumpa Toshiba Estia<\/a> bi bila dobar izbor.<\/p>\n

Za\u0161to bi trebalo da se opredelite za toplotne pumpe<\/strong><\/h2>\n

Kao \u0161to smo ve\u0107 napomenuli, glavna odlika toplotnih pumpi je energetska efikasnost. Zatim, ove pumpe koriste prirodne izvore energije poput podzemnih voda, zemlje ili vazduha. Iako se po nazivu ne mo\u017ee zaklju\u010diti, toplotne pumpe se leti mogu koristiti za hla\u0111enje. Tako\u0111e, toplotne pumpe su jednostavne za kori\u0161\u0107enje, ne zahtevaju velike tro\u0161kove odr\u017eavanja i garantuju<\/strong> dug vek kori\u0161\u0107enja.<\/p>\n

Kao mana \u010desto se navodi cena. Naime, za na\u0161e standarde cena modela ovih pumpi je vi\u0161a u odnosu na neke druge sisteme grejanja. Me\u0111utim, ovakav sistem je i vi\u0161e nego isplativ jer \u0161tedi elekti\u010dnu energiju.<\/p>\n

Naime, ovakav sistem grejanja je \u010dak 70 % jeftiniji u odnosu na grejanje na struju, drva, ugalj ili gas!<\/p>\n

Na koji na\u010din rade toplotne pumpe<\/strong><\/h2>\n

Kao \u0161to smo rekli, toplotne pumpe<\/strong> mogu koristiti energiju vazduha, zemlje ili vode. U zavisnosti od tipa prirodne energije koju koristi razlikuje se i na\u010din rada same pumpe. Me\u0111utim, svi modeli rade po sli\u010dnom principu.<\/p>\n

Naime, toplotne pumpe rade po obrnutom principu rada fri\u017eidera. Odnosno, toplotne pumpe uzima toplotnu energiju iz okoline i usmeravaju ka objektu. Sve ove pumpe sadr\u017ee rashladni fluid koji preuzima toplotnu energiju iz okoline. Ove modele odlikuju 4 osnovna procesa koji se odvijaju u njima.<\/p>\n

To su: isparavanje, kompresija, kondenzacija i ekspanzija. U fazi isparavanja fluid preuzima toplotnu energiju od zemlje, vazduha ili vode i prelazi u gasovito stanje. Zatim, ovaj gas se pod visokim pritiskom<\/strong> sabija, odnosno kopresuje pri \u010demu se molekuli gasa pribli\u017eavaju jedan drugom.<\/p>\n

Ovaj proces dovodi do sudaranja molekula i pove\u0107anja temperature fluida. U procesu kondenzacije gas predaje toplotnu enegiju sistemu za grejanje. Zbog gubljenja energije gas se kondenzuje i pretvara u te\u010dnost. Za vreme ekspanzije pomo\u0107u posebnog ventila se sni\u017eava pritisak fluida. U ovakvom stanju fluid se vra\u0107a u po\u010detnu fazu, odnosno ponovo mo\u017ee preuzeti energiju od okoline.<\/p>\n

Kao \u0161to smo pomenuli, toplotne pumpe<\/a> se mogu koristiti i za hla\u0111enje. U ovom slu\u010daju, one rade u obrnutom smeru u odnosu na grejanje. Odnosno, rashladni fluid<\/strong> preuzima toplotnu energiju iz prostorija i usmerava je u okolinu.<\/p>\n","protected":false},"excerpt":{"rendered":"
