Abstract

V času, ko se vse bolj zavedamo težav, ki jih našemu okolju povzroča uporaba različnih sintetičnih hladiv v hladilnih sistemih, postaja vse bolj aktualna uporaba naravnih hladiv. Mednje sodi tudi amoniak, ki je odlično hladivo, vendar je njegova uporaba še vedno precej omejena zaradi visoke tehnične zahtevnosti, kakor tudi zaradi vprašanja varnosti za zdravje ljudi, ki je povezano z velikimi količinami amoniaka v klasičnih industrijskih hladilnih sistemih. V magistrskem delu so predstavljeni možni ukrepi s katerimi lahko zmanjšamo potrebno količino amoniaka v hladilnem sistemu. Predstavljen je klasičen amoniačni hladilni sistem na primeru hladilnice za ohlajevanje in skladiščenje jabolk. Nato je predstavljen še ekvivalenten hladilni sistem v katerem smo z uporabo nekaterih, v tem magistrskem delu predstavljenih možnih ukrepov, zmanjšali potrebno količino amoniaka za normalno obratovanje sistema za skoraj 85%.

Secondary title:	Low charge ammonia refrigeration systems
Secondary abstract:	Usage of natural refrigerants is becoming more and more popular, partly due to increased awareness of environmental problems caused by synthetic refrigerants. Ammonia is a natural refrigerant with excellent properties, however, its use is still relatively limited due to high technical complexity as well as due to safety and human health concerns associated with large amounts present in conventional industrial refrigeration systems. In the master’s thesis we explore possible measures to reduce the amount of ammonia needed in a refrigeration system. We present a conventional ammonia refrigeration system on an example of a cold store for cooling and storage of apples. Furthermore, we present an equivalent refrigeration system in which the amount of ammonia required for normal operation of the system is reduced by almost 85%.
