Apstrakt
Studija je rađena za Ministarstvo za energiju SAD, da bi se sakupili podaci o karakteristikama projektovanja i izvođenja u procesu razvoja i današnjih
sistema toplotnih pumpi sa cevima u zemlji, zatim procenila pogodnost postojećih metoda projektovanja i odredili istraživačko-razvojni zahtevi
neophodni u podsticanju ove tehnologije. Otkriveno je mnogo istorijskih i sadašnjih istraživanja toplotnih pumpi sa zemljom kao toplotnim izvorom. Proučeno je oko 30 pojedinačnih projekata ove vrste toplotnih pumpi i simulacionih metodologija. Proučavanje je zaključeno time da, uprkos velikom naporu uloženom u eksperimentalni rad u Evropi i u SAD u 40-tim i 50-tim godinama, nije dobijen opšti projektni koncept ove tehnologije. Savremeni istraživački napori prate korišćenje kompjuterizovanih analitičkih tehnika. U Evropi postoji nekoliko dobro razvijenih metodologija projektovanja i načina primene pogodnih za klimu u severnim krajevima. Ipak, nema objavljenih podataka koji bi se mogli koristiti pri projektovanju. Postoji velika neizvesnost u pogledu projektovanja i instalacione prakse sa sistemima prvenstveno namenjenih hlađenju, zbog nepogodnosti modela da koriste podatke o premeštanju vlažnosti i povlačenju tla.
