Toplotni sončni sistemi in sestavni deli - Neserijsko izdelani sistemi - 2. del: Preskusne metode za sončne grelnike vode in kombinirane sisteme
Ta evropski standard se uporablja za majhne in velike neserijsko izdelane sončne ogrevalne sisteme s tekočim sredstvom za prenos toplote za stanovanjske zgradbe in podobne uporabe ter določa preskusne metode za preverjanje zahtev iz standarda FprEN 12977-1. Dokument vsebuje tudi metodo za definicijo toplotne učinkovitosti in predvidevanje sistemske učinkovitosti majhnih neserijsko izdelanih sistemov s pomočjo preskušanja sestavnih delov in simulacije sistema. Poleg tega dokument vsebuje metode za definicijo toplotne učinkovitosti in predvidevanje sistemske učinkovitosti velikih neserijsko izdelanih sistemov. Ta dokument se uporablja za naslednje vrste majhnih neserijsko izdelanih sončnih ogrevalnih sistemov: sisteme za pripravo tople vode v gospodinjstvih, sisteme, namenjene le za segrevanje prostorov, sisteme za pripravo tople vode v gospodinjstvih in segrevanje prostorov ter druge sisteme (npr. vključno s hlajenjem). Ta dokument se uporablja za velike neserijsko izdelane sončne ogrevalne sisteme, predvsem za sončne predogrevalne sisteme, z eno ali več posodami za shranjevanje, toplotnimi prenosniki, ocevjem in samodejnim krmiljenjem ter kolektorskimi polji s prisilnim kroženjem tekočine v zanki kolektorja.
