I-R600a sisikhenkcisi esitsha se-hydrocarbon esisebenza kakuhle.Ithathwe kwizithako zendalo, ezingonakalisi i-ozone, ayinayo impembelelo ye-greenhouse kwaye iluhlaza kunye nokusingqongileyo-friendly.Ibonakaliswa ngubushushu obuphezulu obufihliweyo bokuphuma komphunga kunye nomthamo oqinileyo wokupholisa.Ukusebenza kakuhle kokuhamba, uxinzelelo oluphantsi lokudluliselwa, oluphantsi. ukusetyenziswa kwamandla, ukubuyiswa okucothayo kobushushu bomthwalo.Ihambelana nezithambisi ezahlukeneyo zecompressor, ithatha indawo yeR12.R600a yirhasi enokutsha.Inokuxutywa nomoya ukwenza umxube oqhumayo.Intshukumo yobundlobongela xa udibana ne-oxidant.Umphunga unzima kunomoya kwaye unokunwenwela kude kakhulu kwindawo esezantsi.Kwimeko yomlilo, umthombo uya kubamba umlilo kwaye ulawule.

7.Ifriji R32:

Uninzi lwabasebenzi basefrijini boyika i-R32 xa bethetha ngayo.Iingozi zolu hlobo lwefriji zixhaphakile.Kwiimeko ezininzi, iingozi zokhuseleko zenzeka kwiifriji. Siyayigxininisa into yokuba ukuba kuyimfuneko ukutshintsha iindawo zokulungiswa kwenkqubo yefriji, kufuneka icocwe ngaphambi kokuba usebenze.

I-R32 ubukhulu becala ithatha indawo ye-R22, eyigesi ekwiqondo lobushushu begumbi kunye nolwelo olungenambala olucacileyo olungenambala kuxinzelelo lwalo.Kulula ukunyibilika kwioli kunye namanzi.Nangona inamandla okunciphisa i-ozone, inamandla aphezulu okufudumala kwehlabathi, okuphindwe ngama-550 ngaphezu kwe-carbon dioxide rhoqo emva kweminyaka eyi-100.

Ukufudumala kwehlabathi i-coefficient ye-R32 yefriji yi-1/3 ye-R410A, ehambelana nendalo esingqongileyo kune-R410A yemveli kunye ne-R22 yefriji, kodwa i-R32 inokutsha okuthile. , 8-15 ℃ ubushushu obuphezulu bokukhupha, amandla aphezulu, malunga ne-3-5%, inokusebenza ngokuthelekisa phezulu malunga ne-5%; Ukusebenza okuphezulu, uxinzelelo oluphezulu lokusebenza. Kwimeko efanayo yokusebenza kunye nexesha elifanayo lokusebenza njengecompressor, umthamo wokupholisa. ye-R32 inkqubo imalunga ne-5% ngaphezulu kwaleyo ye-R410A yefriji.

8.Ifriji eyi-R717:

I-ammonia yeyona isetyenziswa kakhulu kuxinzelelo oluphakathi lobushushu obuphakathi kwe refrigerant. Ammonia umgangatho wokuqina kobushushu ngu 77.7 ℃, ubushushu obuphumayo bungama 33.3 ℃, uxinzelelo olujiyayo ngokubanzi kwiqondo lobushushu begumbi yi 1.1 ~ 1.3 MPa, naxa iqondo lobushushu bamanzi ehlotyeni liphezulu. njengoko 30 ℃ ngaphantsi kwe-1.5 MPa.Isetyenziswa ikakhulu kwifriji enkulu yemizi-mveliso kunye nefriji yorhwebo.

Kulula ukuyifumana, ixabiso eliphantsi, uxinzelelo oluphakathi, ukupholisa kweyunithi enkulu, i-coefficient ephezulu ye-exothermic, phantse i-oil enganyibilikiyo, ukuchasana nokuhamba okuncinci, kulula ukuyifumana xa ivuza. kwialloyi zobhedu kunye nobhedu.

9.Ifriji eyi-R290:

I-R290, ipropane, sisibandisi esitsha sokukhusela indalo esingqongileyo.Isetyenziswa ikakhulu kwi-air conditioning, impompo yobushushu, i-air conditioning yasekhaya kunye nezinye izixhobo ezincinci zokukhenkceza. I-R290 ecocekileyo isetyenziswa njengesixhobo sokubona ubushushu. I-R290 yodidi oluphezulu nodidi lokuqala lunokuba yi-R290. isetyenziswa njengefriji yokutshintsha i-R22 kunye ne-R502, ehambelana nenkqubo yokuqala kunye ne-oyile yokuthambisa, kwi-air conditioning esembindini, i-heat pump air conditioning, i-air conditioning yasekhaya kunye nezinye izixhobo ezincinci zokukhenkceza.

Iimvavanyo zibonisa ukuba umyinge we-perfusion oyi-R290 phantsi komthamo wenkqubo efanayo umalunga nama-43% we-R22. Ekubeni ubushushu obufihliweyo bomphunga obuyi-R290 bumalunga nokuphindwe kabini kunobu-R22, ukujikeleziswa kwefriji yenkqubo yesikhenkcisi usebenzisa i-R290 kuncinane kakhulu. Ukusebenzisa irefrigerant yama-R290, umlinganiselo wokonga umbane unokufikelela kwi-10-35%.Isiphene esibulalayo “esinokutsha nesiqhumayo” esingama-R290 siyingozi kakhulu. ubukho bomthombo wobushushu kunye nomlilo ovulekileyo.

I-1.Uxinzelelo lwe-Evaporation luphezulu

Uxinzelelo lwe-evaporation luphezulu: ukuba uxinzelelo lwe-evaporation lwefriji luphantsi kunoxinzelelo lwe-atmospheric, umoya kulula ukungena kwisistim kwaye inkqubo inzima ukujongana nayo.Ngoko ke, kuthenjwa ukuba uxinzelelo lwe-evaporation lwefriji kwiqondo lokushisa eliphantsi lunokuba phezulu kunoxinzelelo lwe-atmospheric.

2.Ubushushu obufihlakeleyo bomphunga bukhulu

Ubushushu obufihliweyo bomphunga bukhulu: ubushushu obufihlakeleyo bomphunga wefriji bukhulu, nto leyo ebonisa ukuba ubushushu obuninzi bunokufunxwa ngokusebenzisa ukupholisa okuncinane.

I-3.Iqondo lokushisa elibalulekileyo liphezulu

Ukuba iqondo lokushisa elibalulekileyo liphezulu, libonisa ukuba ukushisa kwe-coagulation ye-refrigerant kuphezulu, i-refrigerant inokupholisa ngokusebenzisa umoya okhoyo okanye amanzi ukufezekisa umphumo we-condensation liquefaction.

4.Uxinzelelo lwe-condensation luphantsi

Uxinzelelo lokupholisa luphantsi: uxinzelelo lokupholisa luphantsi, lubonisa ukuba i-refrigerant inokunyibilika ngoxinzelelo oluphantsi, kwaye umlinganiselo wokunyanzeliswa kwe-compressor uncinci, onokugcina amandla ehashe we-compressor.

5.Ubushushu bokuqina kufuneka bube phantsi

Iqondo lomkhenkce lisezantsi: indawo yokukhenkceza yesipholisi iphantsi, kungenjalo isisipholisi siyaba ngumkhenkce kwi-evaporator kwaye ayikwazi ukujikeleziswa.

6.Isipholisi segesi sincinci kunomthamo

Umthamo othile wesipholisi segesi uncinci: umncinci umthamo othile wegesi yokupholisa, ngcono, umncinci umthamo wecompressor unokunciphisa iindleko, kwaye umbhobho wokufunxa kunye nombhobho wokukhupha unokusebenzisa umbhobho omncinci wokuhambisa okupholileyo.

7.Isipholisi solwelo sinokuxinana okuphezulu

Okukhona uphezulu ukuxinana kwesipholisi solwelo, kokukhona uphezulu ukuxinana kwesipholisi solwelo, kokukhona unokuba mncinci umbhobho.

8.Inyibilika kwioli engumkhenkce

Inyibilika kwioyile engumkhenkce:Inyibilika kwioyile engumkhenkce: inkqubo ayifuni kufakela isahluli seoyile.

9.Uzinzo lweChemical

Uzinzo lweMichiza: iqondo lobushushu lokuphuma ngumphunga liya kuhluka ngotshintsho lobushushu, njengobushushu bobushushu bomatshini wamanzi omkhenkce ngu-0 ~ 5 ℃, kubanda kwinkqubo yomjikelo wefriji, imidiya ebandayo kuphela utshintsho lomzimba, ngaphandle kokutshintsha kweekhemikhali, hayi ukubola.

10.Akukho mhlwa

Ubushushu obufihliweyo bokuvela komphunga bukhulu: bungenakonakala kwintsimbi kunye nentsimbi, kunye ne-ammonia e-corrosive kwi-copper.I-insulation enhle, ngaphandle koko iya kutshabalalisa i-compressor motor insulation, ngoko ke i-ammonia ayifanele isetyenziswe kwi-compressor evaliweyo, ukuze ugweme ukudibanisa ngokuthe ngqo. ngekhoyili yobhedu.

11.Ayiyoyityhefu engatshayo ayiqhumi

12.Ungonakalisi okusingqongileyo
