Abstract

Det tilveiebringes et kjøleklimaanlegg som også i kalde områder med utetemperaturer på -10° C eller lavere kan fremvise en tilstrekkelig varmekapasitet, idet klimaanleggets varmekapasitet økes mer enn det som er mulig ved konvensjonelle gassinjeksjonssykler. Kjøleklimaanlegget omfatter en kompressor (3), en innendørs varmeveksler (6), en første trykkreduksjonsinnretning (11), og en utendørs varmeveksler (12), alle forbundet med hverandre i en krets for forsyning av vanne fra innendørsvarmeveksleren, kjøleklimaanlegget omfatter en første, indre varmeveksler (9) for varmeveksling mellom kjølemiddel mellom innendørsvarmeveksleren og den første trykkreduksjonsinnnretning og kjølemiddel mellom utendørsvarmeveksleren og kompressoren; en bypassinjeksjonskrets (13) for en del av kjølemiddelet mellom innendørsvarmeveksleren og den første trykkreduksjonsinnretning, for å kunne injisere dette inn i et kompresjonskammer i kompressoren;. en trykkreduksjonsinnretning (14) for injeksjon innrettet i injeksjonskretsen; og en andre, indre varmeveksler (10) for varmeveksling mellom et av trykkreduksjonsinnretningen for injeksjon trykkredusert kjølemiddel og kjølemiddelet mellom innendørsvarmeveksleren og den første trykkreduksjonsinnretning.
