Apstrakt
Odmrzavanje isparivača toplotne pumpe toplim vazduhom eksperimentalno je istraživano u kontrolisanim uslovima, u klimatizovanom vetrenom tunelu. Ovaj posao je zapošet radi nalaženja mogućnosti odmrzavanja isparivača u uslovima u kojima toplotna pumpa ne prestaje da greje. Pri tome je korišćen jedan četvororedni razmenjivač toplote sa pravim rebrima, odozdo snabdeven pretvaračem šarže, radi merenja promene težine i tokom stvaranja leda i njegovog uklanjanja. Stepen otapanja je određivan kao funkcija temperature vazduha, relativne vlažnosti i brzine. Nađeno je da uklanjanje vode, stvorene odmrzavanjem, sa površine razmenjivača, zavisi od brzine vazduha.
