Kutenderera kwekutonhodza kwecompressor ine zvikamu zviviri kunowanzo shandisa macompressor maviri, anoti compressor ine pressure yakaderera uye compressor ine pressure yakakwirira.
1.1 Maitiro ekuwedzera kwegasi rinotonhorera kubva pakumanikidzwa kwekubuda kwemhepo kusvika pakumanikidzwa kwekudzikamisa mhepo akakamurwa kuita zvikamu zviviri
Danho rekutanga: Kudzvanywa kusvika pakumanikidzwa kwepakati necompressor yedanho repasi kutanga:
Danho rechipiri: gasi riri pasi pekumanikidzwa kwepakati rinodzvanywa zvakare kusvika pakumanikidzwa kwekudziya kwemvura necompressor ine kumanikidzwa kwepamusoro mushure mekutonhora kwepakati, uye kutenderera kwekudzokorodza kunopedzisa maitiro ekutonhora.
Pakugadzira tembiricha yakaderera, chinotonhodza chechikamu chekudzikamisa kutonhora chematanho maviri chinoderedza tembiricha yekupinda mufiriji mucompressor yedanho repamusoro, uye chinoderedzawo tembiricha yekuburitsa yecompressor imwechete.
Sezvo kutenderera kwekutonhodza kwezvikamu zviviri kuchiparadzanisa maitiro ese ekutonhodza kuita zvikamu zviviri, chiyero chekumanikidzwa kwechikamu chimwe nechimwe chichava chakaderera zvikuru pane chekumanikidzwa kwechikamu chimwe chete, zvichideredza zvinodiwa zvesimba remuchina uye zvichivandudza zvikuru kushanda kwedanho rekutonhodza. Kutenderera kwekutonhodza kwezvikamu zviviri kwakakamurwa kuita kutenderera kwekutonhodza kwepakati nepakati uye kutenderera kwekutonhodza kwepakati nepakati zvisina kukwana zvichienderana nenzira dzakasiyana dzekutonhodza kwepakati; kana zvichibva panzira yekutonhodza, inogona kukamurwa kuita kutenderera kwekutonhodza kwechikamu chekutanga uye kutenderera kwekutonhodza kwechikamu chechipiri.
1.2 Mhando dzemafiriji ekudzvanya ane matanho maviri
Mazhinji ema "compression refrigerant systems" ane matanho maviri anosarudza ma "refrigerant" ari pakati nepakati neakaderera. Ongororo yekuyedza inoratidza kuti R448A neR455a zvinotsiva R404A zvakanaka pakushandisa simba zvakanaka. Kana zvichienzaniswa nezvimwe zvinoshandiswa panzvimbo pe "hydrofluorocarbons", CO2, semvura inoshanda zvakanaka kune zvakatipoteredza, inogona kutsiva ma "hydrofluorocarbon refrigerants" uye ine hunhu hwakanaka kune zvakatipoteredza.
Asi kutsiva R134a neCO2 kunokanganisa mashandiro esystem, kunyanya kana tembiricha yakakwira, kumanikidzwa kwesystem yeCO2 kwakanyanya uye kunoda kurapwa kwakakosha kwezvikamu zvakakosha, kunyanya compressor.
1.3 Tsvagiridzo yekuvandudza kutonhora kwemhepo ine zvikamu zviviri
Parizvino, mhedzisiro yekutsvagisa kwekugadzirisa kwehurongwa hwekudziya kwefriji hwematanho maviri ndiyo inotevera:
(1) Paunenge uchiwedzera huwandu hwemitsara yemachubhu muintercooler, kuderedza huwandu hwemitsara yemachubhu muair cooler kunogona kuwedzera nzvimbo yekuchinjana kwekupisa kweintercooler ukuwo kuderedza kuyerera kwemhepo kunokonzerwa nehuwandu hwakawanda hwemitsara yemachubhu muair cooler. Kudzokera kunzvimbo yayo yekupinda, kuburikidza nekuvandudzwa kwataurwa pamusoro apa, tembiricha yekupinda yeintercooler inogona kuderedzwa neinenge 2°C, uye panguva imwe chete, mhedzisiro yekutonhodza yeair cooler inogona kuvimbiswa.
(2) Chengetedza frequency yecompressor ine low-pressure constant, uye shandura frequency yecompressor ine high-pressure, nokudaro uchinje ratio yehuwandu hwegasi rinouya necompressor ine high-pressure. Kana tembiricha ye evaporation ikaramba iri pa -20°C, COP yepamusoro i3.374, uye frequency yepamusoro. Chiyero chegasi rinouya neCOP i1.819.
(3) Nekuenzanisa masisitimu akawanda eCO2 transcritical maviri-stage compression refrigeration systems, zvinogumiswa kuti tembiricha yekubuda kwegasi rinotonhodza uye kushanda kwecompressor yedanho repasi zvine simba guru padanho remhepo padanho rakati, saka kana uchida kuvandudza kushanda kwesisitimu, zvakakosha kuderedza tembiricha yekubuda kwegasi rinotonhodza uye kusarudza compressor yedanho repasi ine kushanda kwakanyanya.
