Tehnike odtaljevanja sreža na uparjalniku toplotne črpalke : zaključna naloga univerzitetnega študijskega programa I. stopnje StrojništvoSedmak, RokNa uparjalniku toplotne črpalke se pri delovanju v hladnih in vlažnih razmerah nabira srež. To je snegu podobna tvorba, ki v kanalih uparjalnika blokira pretok zraka in s tem onemogoča delovanje ... toplotne črpalke. Za odtaljevanje sreža obstaja več tehnik, pri komercialnih toplotnih črpalkah prevladuje tehnika odtaljevanja z obrnjenim ciklom. V nalogi so analizirane meritve delovanja toplotne črpalke z obrnjenim ciklom odtaljevanja sreža. Analiza zajema obratovanje toplotne črpalke v enem dnevu, ko so razmere za nastanek sreža ugodne. Za analizirane razmere je določena potrebna moč za predgretje zraka, s katerim bi se izognili nastanku sreža na uparjalniku. Predstavljena je rešitev predgrelnika zraka z uporabo toplote podhlajenega hladiva. Rešitev se izkaže za neučinkovito ker s podhlajevanjem ne zagotovimo potrebne moči za predgrevanje, kot pa tudi energijsko neučinkovit proces. V zaključku je predstavljena še ena zasnova toplotne črpalke, ki nakazuje potencial pri učinkovitosti delovanja in odtaljevanja sreža.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [R.
