Isicelo
Ukutshalwa kwe-lettuce
Imfuneko ebalulekile yokutshala i-lettuce I-HVAC:
Indlu yokugcina izitshalo ingavikela izitshalo ezimweni zezulu ezimbi ezivumela ukukhiqizwa konyaka wonke futhi ibe nokulawula okungcono kokuvikela izinambuzane nezifo, futhi isazuza ekukhanyeni kwemvelo kwelanga. Isimo sezulu esifanele sokutshala i-lettuce kufanele sigcine izinga lokushisa elilinganayo kanye nomswakama ongu-21℃ no-50~70%. Izinga lokushisa langaphakathi, umswakama, ukulawulwa kwe-carbon dioxide kanye nokunisela okwanele yizinto ezibaluleke kakhulu ekutshalweni kwe-lettuce.
Izinga lokushisa lendawo kanye nomswakama:28~30℃/70~77%
Umklamo we-HVAC wangaphakathi:21℃/50~70%. Isikhathi sasemini: izinga lokushisa elihlala njalo kanye nomswakama; Isikhathi sasebusuku: izinga lokushisa elihlala njalo.
Isixazululo sephrojekthi:
1. Umklamo we-HVAC: Isixazululo sokushisa nomswakama sangaphakathi
1. Izingcezu ezimbili zamayunithi angaphandle ancibilikisayo (Umthamo wokupholisa: 75KW * 2)
2. Ingxenye eyodwa yeyunithi yokuphatha umoya eqondile (Umthamo wokupholisa: 150KW, umthamo wokushisa kagesi: 30KW)
3. Ingxenye eyodwa yesilawuli sokushisa nomswakama esingaguquki se-PLC
Umoya owanele ubaluleke kakhulu ekukhuleni kwezitshalo kahle, ikakhulukazi uma kunezinga lokushisa eliphezulu langaphandle kanye nemisebe yelanga. Ukushisa kumele kususwe njalo ku-greenhouse. Uma kuqhathaniswa nomoya womoya wemvelo, i-AHU enokulawulwa kwe-PLC ingathola ngokunembile izimo zezulu ezidingekayo; inganciphisa izinga lokushisa, ikakhulukazi ngaphansi kwamazinga okushisa aphezulu noma amazinga aphezulu emisebe. Ngomthamo wokupholisa ophezulu ingagcina i-greenhouse ivaliwe ngokuphelele, ngisho nasezingeni eliphezulu lemisebe. I-AHU ingaphinde inikeze isisombululo sokususa umswakama esisebenza kahle ukuze kugwenywe ukuminyana emini futhi ikakhulukazi emahoreni ambalwa ngemva kokushona kwelanga.
2. Umklamo we-HVAC: Isixazululo sokulawula i-CO2 yangaphakathi
1. Ingcezu eyodwa yomshini wokupholisa amandla (3000m3/h, ukushintsha umoya kanye ngehora)
2. Ingxenye eyodwa yenzwa ye-CO2
Ukucebisa nge-CO2 kubalulekile ukuze kwandiswe ikhwalithi yemikhiqizo. Uma kungekho izinto zokwenziwa, izindawo zokugcina izithombo kufanele zingene umoya phakathi nengxenye enkulu yosuku kwenza kube nzima ukugcina ukugcwala okuphezulu kwe-CO2. Ukugcwala kwe-CO2 ngaphakathi kwendlu yokugcina izithombo kumele kube ngaphansi kunangaphandle ukuze kutholakale ukugeleza ngaphakathi. Kusho ukuhweba phakathi kokuqinisekisa ukungena kwe-CO2 nokugcina izinga lokushisa elanele ngaphakathi kwendlu yokugcina izithombo, ikakhulukazi ngezinsuku ezinelanga.
I-ventilator yokubuyisa amandla ene-sensor ye-CO2 inikeza ikhambi elihle kakhulu lokucebisa i-CO2. I-sensor ye-CO2 iqapha izinga lokuhlushwa ngaphakathi futhi ilungise ngokunembile ukukhipha nokunikeza ukuhamba komoya ukuze kufezwe ukucebisa i-CO2.
3. Ukunisela
Siphakamisa ukusebenzisa i-water chiller eyodwa kanye nethangi lamanzi elivikela ukushisa. Umthamo wokupholisa i-water chiller: 20KW (enama-outlet abandayo angu-20℃ @ambient angu-32℃)
