Odprt ogrevalni sistem<\/strong> je ogrevalni sistem, kjer lahko voda, ki se uporablja za izmenjavo toplote, pride v stik z atmosfero. Tak\u0161ni sistemi vklju\u010dujejo odprte ekspanzijske posode, ki omogo\u010dajo pretok zraka v sistem in iz njega, kar lahko povzro\u010di izgubo vode in potrebo po rednem polnjenju.<\/p>\n

Odprti ogrevalni sistem praviloma deluje na gravitacijskem principu in ne zahteva avtomatizacije. Po eni strani je ta tradicionalna hidravli\u010dna napeljava kotla ali pe\u010di zastarela, vendar je ravno ta oblika ogrevalnega kompleksa tista, ki vam omogo\u010da doseganje avtonomije.<\/p>\n

Odprti ogrevalni sistem: glavne zna\u010dilnosti<\/h3>\n
    \n
  1. Pu\u0161\u010danje sistema<\/strong>: Voda pride v stik z atmosfero, kar zahteva ob\u010dasno dodajanje vode, da se prepre\u010di pu\u0161\u010danje.<\/li>\n
  2. Ekspanzijska posoda<\/strong><\/a>: Obi\u010dajno se nahaja na vrhu sistema in je izpostavljen zraku, da kompenzira spremembe prostornine vode zaradi temperaturnih nihanj.<\/li>\n
  3. Nevarnost korozije<\/strong>: Odprti sistemi so bolj dovzetni za korozijo, ker lahko kisik v zraku pospe\u0161i oksidacijo kovinskih delov sistema.<\/li>\n
  4. Odstranjevanje zraka<\/strong>: Ker lahko zrak vstopi v sistem, je treba namestiti naprave za odstranjevanje zra\u010dnih zapor in prepre\u010devanje kavitacije v \u010drpalkah.<\/li>\n<\/ol>\n

    Odprti sistemi se pogosto uporabljajo v starej\u0161ih stavbah ali manj zapletenih ogrevalnih napeljavah, kjer enostavna namestitev in vzdr\u017eevanje nadomestita morebitne slabosti.<\/p>\n

    V sodobnih sistemih v nekaterih primerih kombinirajo gravitacijski sistem ogrevanja s prisilnim kro\u017eenjem v primeru pomanjkanja elektri\u010dne energije. Tak\u0161na hidravlika zahteva premi\u0161ljen pristop, vendar jo odlikujeta avtonomija in visoka stopnja udobja zaradi klimatske naprave.<\/p>","protected":false},"excerpt":{"rendered":"
