Nhoroondo yeKambani
Iyo yemvura nitrogen unit inogadzirwa neyedu unit inotora Pressure Swing Adsorption (PSA) kugadzirira yakachena nitrogen, iyo inozoputirwa neyakavhenganiswa-gasi joule-thomson Refrigeration Cycle, MRC ipfupi) kuburitsa inodiwa mvura nitrogen.

Ichitaura nezve firiji inoratidzwa muMufananidzo 1, mashandiro ayo ndeaya: yakaderera-kumanikidza fluid firiji pane ambient tembiricha T0 (inoenderana nehurumende poindi 1s) inomanikidzwa kuita yakakwira-yakamanikidza yakanyanya-tembiricha gasi (nyika poindi 2) necompressor, uye yobva yapinda inotonhorera, nezvimwewo. 5, iyo tembiricha inodonha, uye inopinda mu evaporator kuti ipe inotonhorera Kana tembiricha ikakwira kunongedza 6, inopinda munzira yakadzvinyirira yeanodzokorodza kupisa exchanger, uye painenge ichitonhodza yakakwira-yekumanikidza inouya kuyerera, tembiricha yayo inodzokera zvishoma nezvishoma kunongedzera 1, uyezve inopinda pombi inobatanidza iyo inopisa exchanger uye iyo compressor. Panogona kuve nechikamu chehurongwa panguva ino Kupisa kwekupisa, iyo tembiricha inokwira kusvika patembiricha, inodzokera kunzvimbo yenyika kwe1 sekondi, uye iyo system inopedzisa kutenderera. Iyo firiji system zvishoma nezvishoma inoderedza iyo tembiricha zvinoenderana neiri pamusoro maitiro, uye pakupedzisira inopa firiji inokwana pane yakatarwa firiji tembiricha Tc. Zvekugovaniswa tembiricha mutoro kutonhodza, iyo inotonhorera inokwenenzverwa inogoverwa panguva yeiyo reflux maitiro, senge echisikigo gasi liquefaction, nezvimwe.
Hunhu hweiyo yakasanganiswa firiji kudzikinya firiji
1) Kukurumidza kutanga-up uye nekukurumidza kutonhora chiyero. Kubudikidza neyakavhenganiswa yefriji yevasungwa chiyero, compressor kugona kugadziridza uye throttle vheji yekuvhura kutonga, zvinokurumidza kutonhora zvinodiwa zvinogona kuwanikwa;
2) Maitiro acho ari nyore, huwandu hwemidziyo idiki, uye kuvimbika kwesisitimu kwakakwirira. Izvo zvinhu zvikuru zveiyo system zvinotora vakura compressors, kupisa zvinopisa uye zvimwe zvishandiso mundima yefriji. Iyo sisitimu ine kuvimbika kwakakwirira uye hwakawanda hwakawanda hwezvishandiso zvemidziyo.
Iyo yekuvandudza mutengo weiyo yakavhenganiswa firiji yemvura senitrogen unit inonyanya kusanganisira zvikamu zviviri: PSA nitrogen jenareta unit uye MRC liquefaction unit. Iyo PSA nitrogen jenareta yakura zvakanyanya uye zviri nyore kutenga mumusika wepamba.
