Abstract
Det omtales en fremgangsmåte og tilhørende system for regulering av kjølekapasiteten for et kjølesystem som benytter en gassekspansjonskjølekrets der kjøleprinsippet er ekspansjon av en eller flere gassformige kjølemiddelstrømmer fra et høyere trykk til et lavere trykk, kjennetegnet ved de følgende trinn: - å redusere kjølemiddelmengde som sirkuleres i kjølekretsen (100) midlertidig ved at en andel gassformig kjølemiddel forkjøles ved et høyere trykk og trekkes ut av kjølekretsen (100), - å ekspandere en andel nedkjølt gassformig kjølemiddel over en ekspansjonsinnretning (102) til et lavere trykk slik at det skilles ut minst en andel av kjølemiddelet i form av kald væske, - å separere den utskilte væsken fra den ikke-kondensert gass for midlertidig lagring i en lagringsenhet (104), slik at væsken midlertidig ikke sirkuleres i den ellers lukkede kjølekretsen (100), - å deretter tilbakeføre midlertidig lagret væskeformig kjølemiddel fra lagringsenheten (104) til kjølekretsen (100) ved behov, og - å returnere ikke-kondensert gass og gassfordampet kjølemiddel fra lagingsenheten (104) til egnet sted i kjølekretsen (100).
