Isicelo
Ukulima ilettuce
Imfuneko ephambili yokulima ilettuce I-HVAC:
Indlu yokugcina izityalo ingakhusela izityalo kwiimeko zemozulu ezimbi ezivumela imveliso yonyaka wonke kwaye ibe nolawulo olungcono lokukhusela izinambuzane nezifo, kwaye isazuza ekukhanyeni kwelanga kwendalo. Imeko yemozulu efanelekileyo yokulima ilettuce kufuneka igcine ubushushu obungaguqukiyo kunye nomswakama obuyi-21℃ kunye nama-50~70%. Ubushushu bangaphakathi, ukufuma, ulawulo lwekhabhoni dayoksayidi kunye nokunkcenkceshela okwaneleyo zezona zinto zibalulekileyo ekulimeni ilettuce.
Ubushushu bendawo kunye nokufuma:28~30℃/70~77%
Uyilo lwe-HVAC lwangaphakathi:21℃/50~70%. Ixesha lasemini: ubushushu obungaguqukiyo kunye nokufuma; Ixesha lasebusuku: ubushushu obungaguqukiyo.
Isisombululo seprojekthi:
1. Uyilo lwe-HVAC: Isisombululo sobushushu kunye nokufuma ngaphakathi
1. Iziqwenga ezimbini zeeyunithi zangaphandle ezijiyayo (Umthamo wokupholisa: 75KW * 2)
2. Iyunithi enye yokuphatha umoya ngokuthe nkqo (Umthamo wokupholisa: 150KW, umthamo wombane wokufudumeza: 30KW)
3. Inxalenye enye ye-PLC yokulawula ubushushu obungaguqukiyo kunye nokufuma
Umoya owaneleyo ubaluleke kakhulu ekukhuleni kwezityalo kakuhle, ingakumbi xa kukho amaqondo obushushu aphezulu angaphandle kunye nemitha yelanga. Ubushushu kufuneka bususwe rhoqo kwi-greenhouse. Xa kuthelekiswa nomoya wendalo, i-AHU enolawulo lwe-PLC inokufumana ngokuchanekileyo iimeko zemozulu ezifunekayo; inokunciphisa ngakumbi amaqondo obushushu, ingakumbi xa kukho amaqondo obushushu aphezulu okanye amanqanaba aphezulu emitha. Ngomthamo ophezulu wokupholisa, ingayigcina i-greenhouse ivaliwe ngokupheleleyo, nokuba kumanqanaba aphezulu emitha. I-AHU inokubonelela ngesisombululo sokukhupha umswakama esisebenza kakuhle ukuthintela ukufuma emini kwaye ingakumbi emva kweeyure ezimbalwa emva kokutshona kwelanga.
2. Uyilo lwe-HVAC: Isisombululo solawulo lwe-CO2 yangaphakathi
1. Isixhobo esinye somoya wokubuyisa amandla (3000m3/h, ukutshintsha umoya kube kanye ngeyure)
2. Inxalenye enye ye-sensor ye-CO2
Ukutyetyiswa kwe-CO2 kubalulekile ekwandiseni umgangatho wemveliso. Ukuba akukho zinto zokwenziwa, ii-greenhouse kufuneka zingene umoya ixesha elide emini, oko kwenza kube nzima ukugcina uxinano lwe-CO2 oluphezulu. Uxinano lwe-CO2 ngaphakathi kwe-greenhouse kufuneka lube ngaphantsi kunangaphandle ukuze kufunyanwe ukuhamba ngaphakathi. Oku kuthetha ukutshintshiselana phakathi kokuqinisekisa ukungena kwe-CO2 kunye nokugcina ubushushu obaneleyo ngaphakathi kwe-greenhouse, ingakumbi ngeentsuku ezinelanga.
Iventilator yokubuyisela amandla enesenzi seCO2 ibonelela ngesisombululo esifanelekileyo sokufunxa iCO2. Isenzi seCO2 sijonga inqanaba loxinzelelo lwangaphakathi ngexesha langempela kwaye silungise ngokuchanekileyo i-extract kwaye sinikezele ngokuhamba komoya ukuze kufezekiswe ukufunxa iCO2.
3. Ukunkcenkceshela
Sicebisa ukuba kusetyenziswe i-water chiller enye kunye ne-thermal insulation water tank. Umthamo wokupholisa i-water chiller: 20KW (kunye namanzi abandayo aphumayo angama-20℃ @ambient angama-32℃)
Ixesha lokuthumela: Matshi-26-2021
