Zvinodiwa zvikuru pakurima lettuce HVAC:
Greenhouse inogona kudzivirira zvirimwa kubva mumamiriro ekunze asina kunaka zvichibvumira kugadzirwa kwegore rose uye kuva nekudzivirira kuri nani zvipembenene nezvirwere, uye ichiri kubatsirwa nechiedza chezuva. Mamiriro ekunze akakodzera ekurima lettuce anofanira kuchengetedza tembiricha yakagadzikana uye hunyoro hwe21℃ uye 50~70%. Tembiricha yemumba, hunyoro, kudzora kabhoni dioxide uye kudiridza kwakakwana ndizvo zvinhu zvinonyanya kukosha pakurima lettuce.
Tembiricha yemunzvimbo uye hunyoro:28~30℃/70~77%
Dhizaini yeHVAC yemukati:21℃/50~70%. Nguva yemasikati: tembiricha yakagadzikana uye hunyoro hwakafanana; Nguva yehusiku: tembiricha yakagadzikana.
Mhinduro yepurojekiti:
1. HVAC Design: Mhinduro yekupisa nekunyorova mumba
1. Zvidimbu zviviri zvemayuniti ekunze anodzikamisa (Kukwanisa kutonhora: 75KW * 2)
2. Chikamu chimwe chete chemuchina wekubata mhepo wakamira (Kukwanisa kutonhora: 150KW, kugona kwemagetsi kupisa: 30KW)
3. Chikamu chimwe chePLC chinodzora tembiricha uye hunyoro nguva dzose
Kufefetera kwakakwana kwakakosha zvikuru kuti zvirimwa zvikure zvakanaka, kunyanya kana paine tembiricha yakakwira yekunze uye mwaranzi yezuva. Kupisa kunofanira kubviswa nguva dzose kubva mugreenhouse. Zvichienzaniswa nemhepo inofefetera yechisikigo, AHU ine PLC control inogona kuwana mamiriro ekunze anodiwa; inogona kuderedza tembiricha zvakanyanya, kunyanya kana tembiricha yakakwira kana mwaranzi yakakwira. Nekukwanisa kutonhora kwakanyanya inogona kuchengetedza greenhouse yakavharwa zvachose, kunyangwe pamwaranzi yakanyanya. AHU inogona zvakare kupa mhinduro yekubvisa hunyoro isingashandise simba zvakanyanya kudzivirira kutonhora kwemvura masikati uye kunyanya maawa mashoma mushure mekunyura kwezuva.
2. Dhizaini yeHVAC: Mhinduro yekudzora CO2 yemukati
1. Chidimbu chimwe chemhepo inofefetedza simba (3000m3/awa, kuchinja mhepo kamwe chete paawa imwe neimwe)
2. Chikamu chimwe chete chesensa yeCO2
Kuwedzerwa kweCO2 kwakakosha kuti zvirimwa zviwedzere kunaka. Kana pasina zvinhu zvekugadzira, magreenhouse anofanira kufefeterwa mukati mezuva, saka hazvizodhuri kuchengetedza huwandu hweCO2 hwakawanda. Kuwanda kweCO2 mukati megreenhouse kunofanira kunge kwakaderera pane kwekunze kuti mvura ipinde mukati. Izvi zvinoreva kutengeserana pakati pekuona kuti CO2 inopinda uye kuchengetedza tembiricha yakakwana mukati megreenhouse, kunyanya panguva yezuva.
Muchina wekufema unodzoreredza simba une CO2 sensor unopa mhinduro yakanaka yekuwedzera CO2. Sensor yeCO2 inotarisa huwandu hwemukati memhepo uye inogadzirisa zvakanonanga kuburitsa uye kupa mweya kuti uwane kuwedzera CO2.
3. Kudiridza
Tinokurudzira kushandisa chitofu chimwe chete chemvura uye tangi remvura rinopisa. Kukwanisa kutonhora kwechitofu chemvura: 20KW (nemvura inotonhorera inobuda ye20℃ @ ambient ye32℃)
Nguva yekutumira: Kurume-26-2021
