I-fan wet wet curtain cooling system iyindlela yokupholisa esetshenziswa njengamanje futhi idume ku-greenhouse yokukhiqiza izimbali, enomthelela omangalisayo futhi elungele ukukhula kwezitshalo. Ngakho-ke indlela yokufaka uhlelo lwamakhethini we-fan wet ngokunengqondo ekwakhiweni kwe-greenhouse yembali ukunikeza ukudlala okugcwele kumphumela wayo. Ingabe ukukhula kwembali kunendima ekuyithuthukiseni?

Isimiso sesistimu

Okokuqala, masiqonde isimiso sokusebenza kwefeni eliphansi: lapho umoya oshisayo wangaphandle umuncwa ngekhethini elimanzi eligcwele amanzi, amanzi asekhethini elimanzi abamba ukushisa futhi ahwamuke, ngaleyo ndlela ehlise izinga lokushisa lomoya ongena endaweni ebamba ukushisa. . Ngokuvamile, udonga lwamakhethini olumanzi oluhlanganisa i-pad emanzi, uhlelo lokusabalalisa amanzi lwe-pad emanzi, iphampu yamanzi kanye nethangi lamanzi lakhiwa ngokuqhubekayo eceleni kodonga olulodwa lwe-greenhouse, kuyilapho abalandeli begxilile kwenye i-gable ye-greenhouse. . Ikhethini elimanzi kufanele ligcinwe limanzi ukuze kuqinisekiswe ukuqedwa kwenqubo yokupholisa ehwamukayo. Ngokusho kobukhulu kanye nendawo ye-greenhouse, fan efanelekile ingafakwa odongeni olubhekene nekhethini elimanzi ukwenza umoya ugeleze kahle ku-greenhouse.

Umthelela wokupholisa okuhwamukayo uhlobene nokomisa komoya, okungukuthi, umehluko phakathi kwezinga lokushisa lebhalobhu elimanzi kanye nezinga lokushisa elilomile lomoya. Umehluko phakathi kwezinga lokushisa le-bulb elomile nelimanzi lomoya awuhlukani kuphela ngendawo yendawo kanye nenkathi, kodwa futhi ngaphakathi kwe-greenhouse. Nakuba izinga lokushisa lebulb elomile ku-greenhouse lingahluka ngokufika ku-14°C, izinga lokushisa lebulb elimanzi liyahlukahluka cishe nge-1/3 kuphela yomswakama webulb elomile. Ngenxa yalokho, uhlelo lokuhwamuka kwamanzi lusakwazi ukupholisa phakathi namahora asemini ezindaweni ezinomswakama ophezulu, okudingekayo nasekukhiqizeni i-greenhouse.

umgomo wokukhetha

Umgomo wokukhetha wesayizi wephedi emanzi ukuthi uhlelo lwephedi olumanzi kufanele lufinyelele umphumela oyifunayo. Ngokuvamile amakhethini amanzi anogqinsi angu-10 cm noma angu-15 cm avame ukusetshenziswa ezindlini zokukhiqiza izimbali. Iphedi eliwugqinsi elingu-10 cm eligijima ngesivinini somoya esingu-76 m/min phakathi kwephedi. Iphedi lephepha elingu-15 cm eliwugqinsi lidinga isivinini somoya esingu-122 m/min.

Ubukhulu bekhethini elimanzi okufanele ukhethe akufanele licabangele indawo yendawo kanye nezimo zezulu zendawo, kodwa futhi ibanga phakathi kwekhethini elimanzi kanye ne-fan ku-greenhouse kanye nokuzwela kwezitshalo zezimbali ekushiseni. Uma ibanga phakathi kwefeni nekhethini elimanzi likhudlwana (ngokuvamile lingaphezu kwamamitha angu-32), kunconywa ukusebenzisa ikhethini elimanzi elingu-15 cm; uma izimbali ezitshaliwe zizwela kakhulu ekushiseni kwe-greenhouse futhi zinokubekezelela okubi ekushiseni okuphezulu, kunconywa ukusebenzisa ikhethini elimanzi elingu-15 cm. Ikhethini elimanzi. Ngakolunye uhlangothi, uma ibanga eliphakathi kwekhethini elimanzi kanye nefeni ku-greenhouse lincane noma izimbali zingazweli kakhulu ekushiseni, kungasetshenziswa ikhethini elimanzi elingu-10 cm. Ngokombono wezomnotho, intengo yekhethini elimanzi eliwugqinsi elingu-10 cm liphansi kunalelo lekhethini elimanzi elingu-15 cm, okuyi-2/3 kuphela yenani layo. Ngaphezu kwalokho, ubukhulu bokungena komoya kwekhethini elimanzi bukhulu, kungcono. Ngenxa yokuthi ubukhulu bokungena komoya buncane kakhulu, ukucindezela okumile kuzokwanda, okuzonciphisa kakhulu ukusebenza kahle kwefeni futhi kwandise ukusetshenziswa kwamandla.

Izindlela zokulinganisa imishini yokupholisa yezindawo zokugcina izithombo zendabuko ezinama-multi-span:

1. Umthamo wokungenisa komoya odingekayo we-greenhouse = ubude be-greenhouse × ububanzi × 8cfm (Qaphela: i-cfm iyunithi yokugeleza komoya, okungukuthi, ama-cubic feet ngomzuzu). Ivolumu yokungenisa komoya endaweni ngayinye yeyunithi kufanele ilungiswe ngokuya ngobude nokuqina kokukhanya.

2. Linganisa indawo edingekayo yekhethini elimanzi. Uma kusetshenziswa ikhethini elimanzi eliwugqinsi elingu-10 cm, indawo yekhethini emanzi = umthamo wokungenisa umoya odingekayo we-greenhouse / isivinini somoya 250. Uma kusetshenziswa ikhethini elimanzi elingu-15 cm, indawo yekhethini emanzi = umthamo wokungenisa umoya odingekayo we-greenhouse / isivinini somoya 400. Hlukanisa indawo yephedi emanzi ebaliwe ngobude bodonga lokungenisa umoya olumbozwe iphedi elimanzi ukuze uthole ukuphakama kwephedi elimanzi. Ezindaweni ezinomswakama, umthamo womoya wefeni kanye nosayizi wamakhethini omanzi kufanele ukhuliswe ngo-20%. Ngokusho kwesimiso sokuthi umoya oshisayo uphezulu futhi umoya obandayo uphansi, ikhethini elimanzi le-fan kufanele lifakwe ngaphezu kwe-greenhouse, futhi kuyafana nezindawo zokugcina izithombo ezakhiwe ezinsukwini zokuqala.

Kodwa-ke, eminyakeni yamuva nje, kuye kwaba nokuthambekela kokwehla ekufakweni kwamakhethini ama-fan wet ku-greenhouses. Manje ngesikhathi sokwakhiwa kwe-greenhouse, ngokuvamile i-1/3 yobude befeni ifakwa ngaphansi kombhede wembewu, u-2/3 ngaphezu kwendawo yokutshala imbewu, futhi ikhethini elimanzi lifakwe ku-30 ​​cm ngaphezu komhlaba. Lokhu kufakwa kusekelwe ikakhulukazi ekutshaleni phezu kombhede. Idizayinelwe izinga lokushisa elizwakala isitshalo. Ngoba nakuba izinga lokushisa elingaphezulu kwe-greenhouse liphezulu kakhulu, amaqabunga ezitshalo awakwazi ukukuzwa, ngakho-ke akunandaba. Asikho isidingo sokuchitha ukusetshenziswa kwamandla okungadingekile ukunciphisa izinga lokushisa lezindawo izitshalo ezingakwazi ukuzithinta. Ngesikhathi esifanayo, ifeni ifakwe ngaphansi kombhede wembewu, okuvumela ukukhula kwezimpande zezitshalo.
