Isicelo
Ukulinywa kweLethisi
Iimfuno eziphambili zokulima lettuce HVAC:
I-greenhouse inokukhusela izityalo kwiimeko zemozulu ezimbi ezivumela imveliso yonyaka wonke kwaye ibe nolawulo olungcono lokukhusela izitshabalalisi kunye nezifo, kwaye isaxhamla kukukhanya kwemvelo kwelanga.Imeko yemozulu efanelekileyo ekulinyweni kwelethisi kufuneka igcine ubushushu obungaguqukiyo kunye nokufuma okungama-21℃ kunye nama-50~70%.Ubushushu bangaphakathi endlwini, ukufuma, ulawulo lwekhabhon diokside kunye nokunkcenkceshela okwaneleyo zezona zinto zibalulekileyo ekulinyweni kwe lettuce.
Ubushushu bengingqi & nokufuma:28~30℃/70~77%
Uyilo lweHVAC lwangaphakathi:21℃/50~70%.Ixesha lemini: ubushushu obuqhubekayo kunye nokufuma;Ixesha lasebusuku: ubushushu obuqhubekayo.
Isisombululo seprojekthi:
1. Uyilo lweHVAC: Ubushushu bangaphakathi kunye nesisombululo somswakama
1. Iziqwenga ezibini zokujiya iiyunithi zangaphandle(Umthamo wokupholisa:75KW*2)
2. Iyunithi yokuphatha umoya othe nkqo (Umthamo wokupholisa:150KW, umthamo wokufudumeza kombane:30KW)
3. Inxalenye enye ye-PLC yobushushu obuqhubekayo kunye nesilawuli sokufuma
Ukungena komoya okwaneleyo kubaluleke kakhulu ekukhuleni kwesityalo ngokugqibeleleyo, ngakumbi kwimeko yobushushu obuphezulu bangaphandle kunye nemitha yelanga.Ubushushu kufuneka bususwe rhoqo kwi-greenhouse.Thelekisa umoya wendalo, i-AHU enolawulo lwe-PLC inokufumana ngokuchanekileyo iimeko zemozulu ezifunekayo;inokunciphisa ngakumbi iqondo lobushushu, ngakumbi phantsi kobushushu obuphezulu be-ambient okanye amanqanaba aphezulu emitha.Ngomthamo ophezulu wokupholisa unokugcina i-greenhouse ivaliwe ngokupheleleyo, nokuba kumanqanaba aphezulu emitha.I-AHU inokubonelela ngesisombululo esonga amandla sokususa ubumanzi ukunqanda ukuxinana ngexesha lasemini kwaye ngakumbi iiyure ezimbalwa emva kokutshona kwelanga.
2. Uyilo lwe-HVAC: Isisombululo sokulawula i-CO2 yangaphakathi
1. Iqhekeza elinye le-ventilator yokubuyisela amandla (3000m3 / h, utshintsho lomoya ngexesha elinye ngeyure nganye)
2. Iqhekeza elinye le-CO2 sensor
Ukutyetyiswa kweCO2 kubalulekile ukunyusa umgangatho wemveliso.Xa kungekho zixhobo zokwenziwa, ii-greenhouses kufuneka zifakwe umoya ngexesha lenxalenye enkulu yosuku zenza ukuba kungabi namali ukugcina ugxininiso lwe-CO2 ephezulu.Ukuxinwa kwe-CO2 ngaphakathi kwe-greenhouse kufuneka kube ngaphantsi kunangaphandle ukuze kufumaneke ukuhamba kwangaphakathi.Oku kuthetha ukurhweba phakathi kokuqinisekisa ukungena kweCO2 kunye nokugcina ubushushu obaneleyo ngaphakathi kwendlu eluhlaza, ngakumbi ngeentsuku ezinelanga.
I-ventilator yokubuyisela amandla kunye ne-CO2 sensor ibonelela ngesisombululo esifanelekileyo sokutyebisa i-CO2.I-sensom ye-CO2 yexesha lokwenyani ibeka iliso kwinqanaba logxininiso lwangaphakathi kunye nokulungelelanisa ngokuchanekileyo isicatshulwa kunye nokubonelela ukuhamba komoya ukufezekisa ukutyetyiswa kwe-CO2.
3. Ukunkcenkceshela
Sicebisa ukuba kusetyenziswe i-chiller yamanzi enye kunye ne-thermal insulation water tank.Umthamo wokupholisa wechiller wamanzi:20KW (ngamanzi aphumayo apholileyo angama-20℃@ambient ye-32℃)
