Iyo fan wet wet curtain cooling system inzira yekutonhodza iyo parizvino inoshandiswa uye yakakurumbira mumaruva greenhouse kugadzira greenhouse, ine zvinoshamisa mhedzisiro uye yakakodzera kukura kwechirimwa. Saka maitiro ekuisa iyo fan wet curtain system zvine musoro mukuvakwa kwemaruva greenhouse kuti ipe kutamba kwakazara kuita kwayo. Kukura kwemaruva kune basa here mukukukurudzira?

System musimboti

Chokutanga pane zvose, ngatinzwisisei nheyo yekushanda yepasi fan: kana mhepo inopisa yekunze inoyamwa kuburikidza neketeni remvura rakazadzwa nemvura, mvura iri pamucheka wemvura inotora kupisa uye inoputika, nokudaro kuderedza kupisa kwemhepo inopinda mugreenhouse. . Kazhinji, iyo yakanyorova yejira remadziro rine pedhi rakanyorova, nzira yekugovera mvura yepedhi yakanyorova, pombi yemvura uye tangi remvura inovakwa nguva dzose padivi pemadziro egreenhouse, nepo mafeni akatarisana pane imwe gable yegreenhouse. . Keteni rakanyorova rinofanirwa kuchengetwa rakanyorova kuti ive nechokwadi chekupedzwa kweiyo evaporative kutonhora maitiro. Zvinoenderana nehukuru uye nzvimbo yegreenhouse, fan yakakodzera inogona kuisirwa pamadziro pakatarisana neketeni remvura kuti mweya ufambe zvakanaka kuburikidza negreenhouse.

Mhedzisiro yekutonhodza kwemvura ine chekuita nekuoma kwemhepo, ndiko kuti, mutsauko pakati petembiricha yegirobhu rakanyorova uye tembiricha yegirobhu yakaoma yemhepo. Musiyano uripo pakati pekupisa uye kunyorova kwegirobhu tembiricha yemhepo inosiyana kwete nenzvimbo nenzvimbo uye mwaka, asiwo mukati megreenhouse. Nepo tembiricha yegirobhu rakaoma mugreenhouse ichikwanisa kusiyana nekusvika 14°C, tembiricha yegirobhu yakanyorova inosiyana nechidimbu chechidimbu chehunyoro hwegirobhu rakaoma. Nekuda kweizvozvo, iyo evaporation system ichiri kukwanisa kutonhora mukati memasikati maawa munzvimbo dzine hunyoro hwakanyanya, izvo zvinodiwawo pakugadzira greenhouse.

sarudzo musimboti

Nheyo yekusarudza yekunyorova padhi saizi ndeyekuti iyo wet pad system inofanirwa kuwana inodiwa maitiro. Kazhinji 10 masendimita mukobvu kana 15 masendimita akakora fibrous wet maketeni anowanzoshandiswa mukugadzira maruva greenhouses. A 10 cm gobvu fibrous pad inomhanya pa 76 m/min air velocity nepa padhi. A 15 cm gobvu bepa pad inoda mhepo yemhepo ye122 m/min.

Ukobvu hwejira rakanyorova rekusarudza harifanire kungofunga nezvenzvimbo uye mamiriro ekunze enzvimbo, asiwo chinhambwe pakati pechidzitiro chakanyorova uye feni mugreenhouse uye kunzwisiswa kwezvirimwa zvemaruva kune tembiricha. Kana chinhambwe pakati pefeni nejira rakanyorova chakakura (kazhinji chinodarika 32 metres), zvinokurudzirwa kushandisa 15 cm gobvu remvura keteni; kana maruva akarimwa akanyanya kutaridzika kune tembiricha yegreenhouse uye asina kushivirira kushivirira kwakanyanya, zvinokurudzirwa kushandisa 15 cm gobvu remvura keteni. Wet curtain. Sezvineiwo, kana chinhambwe pakati pechidzitiro chakanyorova uye feni mugreenhouse chiri chidiki kana maruva asinganzwisisi tembiricha, 10 cm gobvu remvura keteni rinogona kushandiswa. Kubva pakuona kwehupfumi, mutengo we 10 cm gobvu jira rakanyorova rakaderera pane iro re 15 cm gobvu remvura keteni, inova 2/3 chete yemutengo wayo. Mukuwedzera, iyo yakakura saizi yemhepo inopinza yejira rakanyorova, zviri nani. Nekuti saizi yemhepo inopinza idiki zvakanyanya, iyo static pressure inowedzera, iyo inozoderedza zvakanyanya kushanda kwe fan uye kuwedzera simba rekushandisa.

Nzira dzekufungidzira kutonhora kwemidziyo yechinyakare yakawanda-span greenhouses:

1. Inodiwa kufefetedza vhoriyamu yegreenhouse = kureba kwegreenhouse × wide x 8cfm (Cherechedza: cfm ichikamu chekuyerera kwemhepo, ndiko kuti, cubic tsoka paminiti). Vhoriyamu yekufemesa pachikamu chepasi inofanira kugadziridzwa zvinoenderana nekukwirira uye kusimba kwechiedza.

2. Ongorora inodiwa nyoro yemaketeni nzvimbo. Kana chidzitiro chemvura chakakora masendimita gumi chikashandiswa, nzvimbo inonyorova yeketeni = iyo inodiwa yekufemesa vhoriyamu yegreenhouse / mhepo yekumhanya 250. Kana 15 cm gobvu remvura keteni rinoshandiswa, iyo inonyorova keteni nzvimbo = inodiwa yekufemesa vhoriyamu yegreenhouse / kumhanya kwemhepo 400. Gurai nzvimbo yakaverengerwa yepedhi neurefu hwemadziro ekufemesa akafukidzwa nepedhi yakanyorova kuti uwane hurefu hwepadhi. Munzvimbo dzine hunyoro, huwandu hwemhepo ye fan uye saizi yeketeni yakanyorova inofanira kuwedzerwa ne20%. Maererano nenheyo yokuti mhepo inopisa yakakwira uye mhepo inotonhora yakadzika, fan fan yemvura yejira inofanira kuiswa pamusoro pe greenhouse, uye zvakafanana kune greenhouses yakavakwa mumazuva ekutanga.

Zvisinei, mumakore achangopfuura, kwave kune maitiro ekuderera mukuiswa kwemaketeni akanyorova fan mudzimba dzegreenhouse. Parizvino mukuvakwa kwegreenhouse, kazhinji 1/3 yehurefu hwe fan inoiswa pazasi pemubhedha wembeu, 2/3 pamusoro penzvimbo yembeu, uye keteni rakanyorova rinoiswa 30 cm pamusoro pevhu. Kuiswa uku kunonyanya kubva pakudyara pamubhedha wepamusoro. Yakagadzirirwa tembiricha inonzwikwa nechirimwa. Nokuti kunyange zvazvo kutonhora kwepamusoro pegreenhouse kwakakwirira kwazvo, mashizha emiti haagoni kuzvinzwa, saka hazvina basa. Hapana chikonzero chekushandisa zvisina kufanira kushandiswa kwesimba kuderedza kutonhora kwenzvimbo idzo zvirimwa zvisingagoni kubata. Panguva imwecheteyo, fan inoiswa pasi pemubhedha wembeu, iyo inobatsira pakukura kwemidzi yemiti.
