Izilumkiso zokukhethwa kwezixhobo zokugcina ezibandayo: i-condenser: i-evaporative cooling xa iimeko zokusebenza ziguquguquka; umoya opholileyo: ukugcinwa kobushushu obuphezulu kusebenzisa ifeni yokupholisa ubushushu obuphantsi, utshintshiselwano lobushushu, ivalve yokwandisa;
icompressor: icompressor yobushushu obuphantsi itsala ukugcinwa kobushushu obuphezulu;
umoya oshushu uyanyibilika Iqabaka: indawo yokugcina impahla ekhawulezayo ukubanda;
iqabaka yokugungxulwa kwamanzi: ubushushu bamanzi;
i-antifreeze yomgangatho: ukungena komoya, ukukhupha umphunga ukutshisa i-ethylene glycol.
2. Ukupholisa ukujiya ukhetho lweyunithi:
1. Iyunithi enye kunye nendawo yokugcina impahla: umthamo wokupholisa iyunithi = 1.1 × umthamo wokupholisa wogcino olubandayo; Ukupholisa ngokupheleleyo umthamo wenkqubo: ubuncwane be-1.1-1.15 kufuneka buthathelwe ingqalelo.
2. Iyunithi enye eneendawo zokugcina izinto ezininzi: umthamo wokupholisa weyunithi = 1.07 × isixa somthamo wokupholisa wendawo yokugcina ebandayo; umthamo wokupholisa ngokupheleleyo wenkqubo: i-7% yelahleko yombhobho kufuneka ithathelwe ingqalelo.
3. Iyunithi ehambelanayo eneendawo ezininzi zokugcina ezibandayo: umthamo wokupholisa iyunithi = P × isixa somthamo wokupholisa wogcino olubandayo;
Umthamo wokupholisa uwonke wenkqubo: ilahleko yombhobho we-7% kunye ne-coefficient yokusebenza kwendawo yokugcina impahla ngexesha elifanayo kufuneka ithathelwe ingqalelo.
Iimeko eziyimfuneko zokukhetha i-air cooler:
Ifriji;
ubushushu bokugcina obubandayo;
ukutshintshana kobushushu;
Ubume bomoya opholileyo;
Ubungakanani bokugcina obubandayo, umgama wokubonelela ngomoya;
Indlela yokunyibilikisa.
Iimeko eziyimfuneko zokukhethwa kwe-air cooler: 1. Isikhenkcezisi: Iifriji ezahlukeneyo zinokutshintshisa ubushushu obuhlukeneyo kunye nokumelana noxinzelelo. I-R404a inotshintshiselwano lobushushu olukhulu kune-R22, malunga ne-1%. 2. Ubushushu bogcino olubandayo: Okukhona usezantsi ubushushu bokugcina obubandayo, kokukhona kuncinci ukutshintshiselana kobushushu kunye nokukhula kwesithuba setshiphu. Khetha ngokuchanekileyo isithuba sesiphelo sesipholisi somoya: isamba;
Umthamo wokupholisa uwonke wenkqubo: ilahleko yombhobho we-7% kunye ne-coefficient yokusebenza kwendawo yokugcina impahla ngexesha elifanayo kufuneka ithathelwe ingqalelo.
3. Ukutshintshana kobushushu:
Ukutshintshana kobushushu bomoya opholileyo ≥ ukusetyenziswa kokupholisa kokugcinwa okubandayo * 1.3 (impembelelo yeqabaka); utshintshiselwano lobushushu obuqhelekileyo: utshintshiselwano lobushushu kwisampulu × i-coefficient yangempela; ukutshintshwa kobushushu phantsi kweemeko zokuyila: utshintshiselwano lwegama Ubushushu × ukulungiswa komlinganiso; i-coefficient yokulungiswa kobushushu bokugcina: iqondo eliphantsi lobushushu bokugcina okubandayo, lincinci utshintshiselwano lobushushu. Final material correction factor: imathiriyeli kunye nobukhulu. I-coefficient yokulungisa i-fin coeating: i-anti-corrosion i-coating iyanciphisa ukutshintshwa kobushushu; i-coefficient yokulungisa umthamo womoya: iimfuno ezikhethekileyo zefeni.
4. Isakhiwo sokupholisa umoya Uhlobo lwesilingi:esetyenziswa ngokuqhelekileyo kwindawo yokugcina ebandayo;
uhlobo lwesilingi: indawo yokuphuma yomoya kabini, indawo yomoya emine, i-air conditioner;
uhlobo lomgangatho: igumbi lomkhenkce elikhawulezayo, okanye ifriji yombhobho womoya.
.Ubungakanani bendawo ebandayo yogcino, umgama wokubonelela komoya, kunye nobukhulu bendawo ebandayo yogcino, ngokulinganayo uvuthuze umoya, kwaye umisele inani leefeni zokupholisa.
5. Ukhetho lwendlela yokuphelisa ubushushu obubandayo:
| UKUGCINWA OKUGCINA UBUSHUSHU | UKUQHUMA |
| +5℃ | Ukutshatyalaliswa kwendalo, |
| 0~4℃ | ukutshitshiswa kombane, ukugungxulwa kwamanzi, |
| -18℃ | ukunyibilika kombane, ukugungxulwa kwamanzi, ukuthomalalisa umoya oshushu |
| -35℃ | ukutshitshiswa kombane, ukugungxulwa kwamanzi, |
