Isicelo
Ukutshala ulethisi
Izidingo ezibalulekile zokutshala ulethisi i-HVAC:
I-greenhouse ingavikela izitshalo esimweni sezulu esibi esivumela ukukhiqizwa konyaka wonke futhi ibe nokulawula okungcono kokuvikela izinambuzane nezifo, futhi isazuza ekukhanyeni kwemvelo kwelanga.Isimo sezulu esikahle sokutshalwa kwe-ulethisi kufanele sigcine izinga lokushisa elihlala njalo kanye nomswakama ongu-21℃ kanye no-50~70%.Ukushisa kwasendlini, umswakama, ukulawulwa kwe-carbon dioxide kanye nokuchelela okwanele yizici ezibaluleke kakhulu ekulinyweni kwe-ulethisi.
Izinga lokushisa lendawo & nomswakama:28~30℃/70~77%
Idizayini ye-HVAC yasendlini:21℃/50~70%.Isikhathi sosuku: izinga lokushisa elihlala njalo kanye nomswakama;Isikhathi sasebusuku: izinga lokushisa elingashintshi.
Isixazululo sephrojekthi:
1. Idizayini ye-HVAC: Izinga lokushisa lasendlini kanye nesixazululo somswakama
1. Izingcezu ezimbili zokujiya kwamayunithi angaphandle(Umthamo wokupholisa:75KW*2)
2. Ucezu olulodwa lweyunithi yokubamba komoya mpo (umthamo wokupholisa:150KW, umthamo wokushisisa kagesi:30KW)
3. Ucezu olulodwa lwe-PLC yesilawuli sokushisa nomswakama esingaguquki
Ukungena komoya okwanele kubaluleke kakhulu ekukhuleni kwesitshalo okufanelekile, ikakhulukazi esimweni samazinga okushisa aphezulu angaphandle kanye nemisebe yelanga.Ukushisa kufanele kususwe njalo ku-greenhouse.Qhathanisa nokungena komoya kwemvelo, i-AHU enokulawula kwe-PLC ingathola ngokunembile izimo zezulu ezidingekayo;ingaqhubeka nokunciphisa izinga lokushisa, ikakhulukazi ngaphansi kwamazinga okushisa aphezulu noma amazinga aphezulu emisebe.Ngomthamo ophezulu wokupholisa ungagcina i-greenhouse ivaliwe ngokuphelele, ngisho namazinga aphezulu emisebe.I-AHU ingase futhi inikeze isisombululo sokususa umswakama esonga amandla ukuze kugwenywe ukuminyana emini futhi ikakhulukazi amahora ambalwa ngemva kokushona kwelanga.
2. I-HVAC Design: Isixazululo sokulawula i-CO2 yangaphakathi
1. Ucezu olulodwa lwe-ventilator yokubuyisela amandla (3000m3/h, ukushintsha komoya kanye ngehora)
2. Ucezu olulodwa lwenzwa ye-CO2
Ukunothiswa kwe-CO2 kubalulekile ukukhulisa ikhwalithi yomkhiqizo.Uma kungekho zimpahla zokwenziwa, izindawo zokugcina izithombo kufanele zifakwe umoya phakathi nengxenye enkulu yosuku kwenza kube kungenamali ukugcina ukuhlushwa okuphezulu kwe-CO2.Ukugcwala kwe-CO2 ngaphakathi kwendawo ebamba ukushisa kufanele kube ngaphansi kunangaphandle ukuze kutholakale ukugeleza kwangaphakathi.Kusho ukuhwebelana phakathi kokuqinisekisa ukungena kwe-CO2 nokugcina izinga lokushisa elanele ngaphakathi kwendawo ebamba ukushisa, ikakhulukazi phakathi nezinsuku libalele.
I-ventilator yokubuyisela amandla enenzwa ye-CO2 ihlinzeka ngesisombululo esiphelele sokucebisa i-CO2.Inzwa ye-CO2 yesikhathi sangempela iqapha ileveli yokuhlushwa yasendlini futhi ulungise ngokunembile ukukhishwa nokunikezela ngokugeleza komoya ukuze kuzuzwe ukunothisa kwe-CO2.
3. Ukunisela
Siphakamisa ukuthi usebenzise i-water chiller eyodwa kanye ne-thermal insulation water tank.Umthamo wokupholisa we-water chiller: 20KW (amanzi aphumayo abandayo angu-20℃@ambient engu-32℃)
