Nekuda kwechando chiri pamusoro pe evaporator mufiriji, chinodzivirira kufambiswa nekupararira kwesimba rekutonhora re evaporator (pipeline), uye pakupedzisira chinokanganisa mhedzisiro yekutonhora. Kana ukobvu hwechando (chando) pamusoro pe evaporator hwasvika pamwero wakati, kushanda kwefiriji kunodzikira kusvika pasi pe30%, zvichikonzera kutambisa simba remagetsi zvakanyanya uye kupfupisa hupenyu hwekushanda kwefiriji. Saka, zvakakosha kuita basa rekudzikisa chando mufiriji panguva yakakodzera.
Chinangwa chekunyungudutsa
1, kuvandudza kushanda zvakanaka kwemuchina wekutonhodza;
2. Iva nechokwadi chekuti zvinhu zvakachengetwa mufiriji zviri mumhando yepamusoro
3, kuchengetedza simba;
4, wedzera hupenyu hwebasa rehurongwa hwekuchengetera zvinhu zvinotonhora.
Nzira yekunyungudutsa
Nzira dzekunyungudutsa chando mufiriji: kunyungudutsa gasi rinopisa (kunyungudutsa fluorine inopisa, kunyungudutsa ammonia inopisa), kunyungudutsa mvura, kunyungudutsa magetsi, kunyungudutsa chando mumashini (yekugadzira), nezvimwewo.
1, gasi rinopisa rinonyungudutsa
Yakakodzera pombi huru, yepakati nediki yekuchengetera inotonhora ichinyungudutsa zvakananga gasi rinopisa rinopisa rinopinda mu evaporator pasina kumisa kuyerera, tembiricha ye evaporator inokwira, uye chando ne cold discharge joint zvinonyunguduka kana kuti zvinobviswa. Kunyungudutsa gasi rinopisa kunodhura uye kwakavimbika, kuri nyore kugadzirisa nekutarisira, uye kuoma kwayo kwekudyara nekuvaka hakuna kukura. Zvisinei, kunewo akawanda marongero ekunyungudutsa gasi rinopisa, tsika yakajairika ndeyekutumira gasi rine simba guru uye rinopisa rinobuda kubva mu compressor kuenda mu evaporator kuti ribudise kupisa nekunyungudutsa, kuitira kuti mvura yakanyungudutswa ipinde mune imwe evaporator kuti itore kupisa uye iende mu tembiricha yakaderera uye ine simba shoma, uye yozodzokera ku compressor suction port kuti ipedzise kutenderera.
2, pfapfaidzo yemvura inonyungudutsa
Inoshandiswa zvakanyanya pakunyungudutsa mafiriji makuru nepakati
Pfafaidza evaporator nemvura inodziya mukamuri nguva nenguva kuti munyungudise chando. Kunyangwe ichinyungudutsa zvakanaka, inonyanya kukodzera ma air coolers, uye zvakaoma kushandisa ma evaporation coils. Zvinokwanisikawo kupfapfaidza evaporator nemushonga une tembiricha yakakwira yechando, senge 5%-8% concentrated brine, kudzivirira chando.
3. Kunyungudutsa kwemagetsi
Kunyungudutsa pombi yemagetsi inodziya kunonyanya kushandiswa mumhepo inotonhorera iri pakati nepakati nepakati; Kunyungudutsa waya yemagetsi inodziya kunonyanya kushandiswa mumachubhu ealuminium anochengetera zvinhu zvinotonhora ari pakati nepakati nepakati.
Kunyungudutsa kupisa kwemagetsi, kune chiller kuri nyore uye kuri nyore kushandisa; Zvisinei, kana iri aluminium tube inotonhorera, kuoma kwekugadzira kwekuisa aluminium fin yewaya yemagetsi yekudziyisa hakusi kudiki, uye mwero wekukundikana wakakwira mune ramangwana, kugadzirisa nekutarisira kwakaoma, hupfumi hwakashata, uye kuchengetedzeka kwakaderera.
4, kunyungudutsa kwemuchina
Kunyungudutsa pombi diki yekuchengetera zvinhu zvinotonhora papombi yekuchengetera zvinhu zvinotonhora nemaoko kunodhura zvishoma, nzira yekutanga yekunyungudutsa zvinhu zvinotonhora haina kunaka, kushanda nesimba kwakaoma, kushandiswa kwemuviri kwakanyanyisa, nguva yekuchengetedza zvinhu mudura yakareba zvakanyanya, zvinokuvadza hutano, kunyungudutsa zvinhu hakusi nyore kupedzisa, zvinogona kukonzera kuchinja kwe evaporator, uye zvinogona kutotyora evaporator uye kukonzera tsaona dzekubuda kwemvura mufiriji.
Sarudzo yemodhi (Sisitimu yeFluorine)
Zvichienderana ne evaporator yakasiyana yekuchengetera zvinhu zvinotonhora, nzira yakakodzera yekunyungudutsa inosarudzwa, uye kushandiswa kwesimba, kushandiswa kwechinhu chekuchengetedza, kuoma kwekuisa uye kushanda zvinoongororwa zvakare.
1, nzira yekunyungudutsa chando yefeni inotonhora
Kune machubhu emagetsi anonyungudutsa uye anogona kunyungudutsa mvura. Nzvimbo dzine mvura iri nyore kushandisa dzinogona kusarudza chitofu chechando chinonyungudutsa mvura, uye nzvimbo dzine kushomeka kwemvura dzinowanzo sarudza chitofu chechando chinonyungudutsa mvura. Chitofu chechando chinonyungudutsa mvura chinowanzo gadzirwa mumhepo yakakura uye mufiriji.
2. Nzira yekunyungudutsa simbi mumutsara
Kune dzimwe nzira dzekunyungudutsa fluorine inopisa uye dzekugadzira.
3. Nzira yekunyungudutsa chando chechubhu yearuminiyamu
Kune nzira dzekubvisa fluoride mu thermal fluoride uye electric thermal defrosting. Nekushandiswa kwakawanda kwealuminium tube evaporator, kusunungura aluminium tube kwave kuchiwedzera kutariswa nevashandisi. Nekuda kwezvikonzero zvezvinhu, aluminium tube haina kukodzera kushandiswa kwesimbi iri nyore uye isina kunaka, saka nzira yekubvisa fluoride mualuminium tube inofanira kusarudza electric wire defrosting uye hot fluorine defrosting, pamwe chete nekushandiswa kwesimba, chiyero chekushanda nesimba uye kuchengetedzeka nezvimwe zvinhu, kusunungura aluminium tube kwakakodzera kusarudza hot fluorine defrosting.
Kunyungudutsa fluoride inopisa
Midziyo yekushandura nzira yekuyerera kwemvura yakagadzirwa zvichienderana nepfungwa yekunyungudutsa gasi rinopisa, kana sisitimu yekushandura ine mavharuvhu akawanda emagetsi (mavharuvhu emaoko) akabatana, kureva, nzvimbo inogadzirisa refrigerant, inogona kuita kuti kunyungudutsa kwefluorine inopisa kushande munzvimbo inotonhorera.
1, chiteshi chekugadzirisa nemaoko
Inoshandiswa zvakanyanya mumasisitimu makuru ekutonhodza akadai sekubatanidza zvinhu zvakafanana.
2, michina yekushandura fluorine inopisa
Inoshandiswa zvakanyanya mufiriji imwe chete diki nepakati. Zvakadai se: mudziyo mumwe chete unopisa unonyungudutsa fluorine.
Kunyungudutsa kamwe chete fluorine inopisa
Yakakodzera system yekutenderera yakazvimirira yecompressor imwe chete (haina kukodzera kuiswa kwekubatanidza kwemayuniti akafanana, akawanda uye anopindirana). Inoshandiswa mukunyungudutsa mapombi madiki nepakati ekuchengetera zvinhu zvinotonhora uye kunyungudutsa chando muindasitiri yechando.
chinhu chinoshamisa
1, kutonga nemaoko, kushandura nekudzvanya kamwe chete.
2, kupisa kubva mukati, chando uye madziro epombi zvinogona kunyunguduka nekudonha, chiyero chekushandisa simba zvakanaka che1:2.5.
3, ichinyungudutsa zvakanaka, inopfuura 80% yechando chakaita sedonhwe rakasimba.
4, zvichienderana nemufananidzo wakaiswa zvakananga pachikamu chekudzikisa mvura, hazvidi zvimwe zvinhu zvakakosha.
5, zvichienderana nemusiyano chaiwo wekupisa kwemhepo, zvinowanzotora maminetsi makumi matatu kusvika zana nemakumi mashanu.
