Claims (11)

1. Kølesystem omfattende: et kølekredsløb (10) omfattende en kompressor (11) og en kølevarmeveksler (14) begge forbundet deri, idet kølekredsløbet (10) fungerer i en kølecyklus ved at cirkulere kølemiddel derigennem; og en intern ventilator (16) til at suge luft ind fra det indre af et koldt opbevaringsrum for at tillade at luften strømmer gennem kølevarmeveksleren (14) og derefter blæse luften ind i det kolde opbevaringsrum, hvor kølesystemet endvidere omfatter en kapacitetsregulator (35) til at regulere kølekapaciteten af kølevarmveksleren (14), og en controller, idet controlleren er konfigureret til, i et første trin, at drive kompressoren (11) og den interne ventilation (16) mens kapacitetsregulatoren (35) regulerer kølekapaciteten af kølevarmeveksleren (14); i et andet trin, at forøge kølekapaciteten af kølevarmeveksleren (14) med kapacitetsregulatoren (35) for at reducere lufttemperaturen på udblæsningssiden til en lavere grænse af et ønsket temperaturinterval omfattende den fastsatte værdi når lufttemperaturen på udblæsningssiden holdes ved den fastsatte værdi i et forudbestemt tidsrum, og derefter, i et tredje trin, at stoppe kompressoren (11) og den interne ventilator (16); og i et fjerde trin, at genstarte driften af kompressoren (11) og den interne ventilator (16) mens kapacitetsregulatoren (35) regulerer kølekapaciteten af kølevarmeveksleren (14) når lufttemperaturen på udblæsningssiden stiger til en øvre grænse af det ønskede temperaturinterval efter det tredje trin.
2. Kølesystem ifølge krav 1, hvor controlleren er konfigureret til at aktivere den interne ventilator ved en lavere luftstrømshastighed end i det første trin når sugesidelufttemperaturen i det kolde opbevaringsrum efter det tredje trin stiger til en forudbestemt grænseværdi.
3. Kølesystem ifølge krav 2, hvor controlleren er konfigureret til at fastsætte grænseværdien på sugesidelufttemperaturen ved en fastsat mængde højere end værdi end sugesidelufttemperaturen ved slutningen på det første trin.
4. Kølesystem ifølge krav 2, hvor luftindgangen er dannet i en øverste del af det kolde opbevaringsrum og en luftudgang er dannet i en nederste del af det kolde opbevaringsrum.
5. Kølesystem ifølge krav 1, controlleren er konfigureret til med mellemrum at drive den interne ventilator (16) ved en lavere luftstrømshastighed end i det første trin efter det tredje trin.
6. Kølesystem ifølge krav 1, hvor controlleren er konfigureret til at aktivere den interne ventilator (16) ved en lavere luftstrømshastighed end i det første trin når et forudbestemt tidsrum er gået efter det tredje trin inden starten på det fjerde trin.
7. Kølesystem ifølge krav 1, hvor controlleren er konfigureret til at reducere den fastsatte værdi for lufttemperaturen på udblæsningssiden for hvert forudbestemt tidsrum.
8. Kølesystem ifølge krav 1, hvor controlleren er konfigureret til tvungent at forlænge driftstidsrummet for det første trin i hvert forudbestemt tidsrum.
9. Kølesystem ifølge krav 1, hvor controlleren er konfigureret til at aktivere den interne ventilator (16) når lufttemperaturen på udblæsningssiden efter det tredje trin falder under den lavere grænse for det ønskede temperaturinterval.
10.
Kølesystem ifølge et hvilket som helst af kravene 1 til 9, hvor kapacitetsregulatoren omfatter en flowregulatorventil (35), forbundet i kølekredsløbet (10), til at regulere mængden af flow af kølemiddel suget ind i kompressoren (11), og controlleren er konfigureret til, ved det tredje trin, at forøge åbningen af flowregulatorventilen (35) for at forøge kølekapaciteten i kølevarmeveksleren (14).
