Klimatske naprave, enote za hlajenje kapljevine, toplotne črpalke za ogrevanje in hlajenje prostora ter procesne hladilne naprave z električnimi kompresorji - 1. del: Izrazi in definicije

Ta evropski standard določa izraze in definicije za ocenjevanje in delovanje klimatskih naprav, enot za hlajenje kapljevine in toplotnih črpalk, ki uporabljajo zrak, vodo ali slanico kot medij za prenos toplote, z električnimi kompresorji, kadar se uporabljajo za ogrevanje in/ali hlajenje prostora.
Določa tudi izraze in definicije za ocenjevanje in delovanje procesnih hladilnih naprav.
Ta evropski standard se ne uporablja za toplotne črpalke za gospodinjsko vročo vodo, čeprav se lahko za njih uporabljajo nekatere definicije.
Ta evropski standard se uporablja za:
–   tovarniško izdelane enote, ki jih je mogoče opremiti s kanali,
–   tovarniško izdelane enote za hlajenje kapljevine z vgrajenimi kondenzatorji ali za uporabo z oddaljenimi kondenzatorji,
–   tovarniško izdelane enote bodisi fiksne ali spremenljive zmogljivosti na kakršen koli način in
–   zračne klimatske naprave, ki lahko poskrbijo tudi za izhlapevanje kondenzata na strani kondenzatorja.
Ta standard zajema pakirane enote in sisteme z enim ali več razcepi. Ta standard zajema enote z enojnim in dvojnim jaškom.
Pri enotah, sestavljenih iz več kosov, se ta evropski standard uporablja samo za tiste, ki so zasnovane in dostavljene kot celoten paket, razen za enote za hlajenje kapljevine z oddaljenim kondenzatorjem.
Ta evropski standard je prvotno namenjen enotam za hlajenje z vodo in slanico, vendar se lahko po dogovoru uporablja tudi za druge tekočine.
Delovanje hlajenja pri enotah, ki kondenzator hladijo z zrakom in z izhlapevanjem zunanje dodatne vode, naj se določi v skladu s standardom EN 15218. Pri enotah, ki lahko delujejo tudi v načinu gretja, se skupina standardov EN 14511 uporablja za določevanje njihovega delovanja pri gretju.
OPOMBA 1:   Preskusi z delnimi obremenitvami enot so obravnavani v standardu EN 14825.
OPOMBA 2:   Vsi simboli v tem besedilu se uporabljajo ne glede na jezik.
