Muaj ntau hom tsev ntsuab nyob hauv qhov kev lag luam no, xws li ib leeg-span greenhouses (qhov chaw ntsuab), thiab ntau cov greenouses (gutter connected greenhouses). Thiab lawv cov khoom npog npog muaj zaj duab xis, polycarbonate board, thiab tempered iav.
Vim tias cov khoom siv tsim kho cov khoom siv muaj ntau yam sib txawv, lawv cov kev ua haujlwm rwb thaiv tsev ua kom sib txawv. Feem ntau hais lus, nrog rau siab siab thermal conductivity ntawm cov ntaub ntawv, tshav kub yog qhov yooj yim hloov. Peb hu rau qhov chaw nrog cov rwb thaiv tsev tsawg ", uas tsis yog lub ntsiab channel ntawm kev kub ntxhov tab sis kuj yog qhov chaw uas tsim nyog cov dej yog qhov yooj yim. Lawv yog cov kev txuas tsis muaj zog ntawm cov rwb thaiv tsev thermal. Qhov dav dav "kev txo qis" yog nyob hauv tsev cog khoom qhov chaw ua haujlwm, cov ntaub thaiv npog phab ntsa, thiab txhuam cov kiv cua lub qhov. Yog li ntawd, kev ntsuas ntsuas kom txo qis cov cua sov poob ntawm qhov "qis-kub siv" yog qhov tseem ceeb ntawm kev txuag hluav taws xob thiab cov rwb thaiv tsev thermal ntawm lub tsev cog khoom.
Lub tsev cog khoom tsim nyog yuav tsum xyuam xim rau kev kho mob ntawm cov "tsawg-kub siv" hauv kev tsim kho. Yog li muaj 2 lub tswv yim rau koj kom txo qis lub thermal poob ntawm "tsawg-kub siv".
TSWV YIM 1:Sim thaiv cov "tsawg-kub siv" txoj kev uas nqa cua sov sab nraud.
Tswv yim 2: Kev ntsuas kev rwb tshwj xeeb tshwj xeeb yuav tsum tau ua rau ntawm "Tsawg-Kub Siv" uas ua kom muaj cua sov sab nraud.
Cov kev ntsuas tshwj xeeb yog raws li hauv qab no.
1. Rau lub tsev cog khoom gutter
Tsev cog khoom gutter muaj txoj haujlwm ntawm kev sib txuas lub ru tsev thiab dej nag thiab ua kua. Qhov gutter feem ntau yog ua los ntawm cov hlau lossis alloy, rwb thaiv tsev kev ua haujlwm tsis zoo, loj tshav kub poob. Cov kev tshawb fawb muaj feem qhia tias cov phiaj loj nyob qis dua 5% ntawm tag nrho cheeb tsam ntawm lub tsev cog khoom, tab sis cov cua sov poob yog ntau dua 9%. Yog li ntawd, cov nyhuv ntawm cov plab zom rau kev txuag hluav taws xob thiab cov rwb thaiv tsev ntawm cov tsev cog khoom tsis tuaj yeem tsis quav ntsej.
Ntawm tam sim no, cov hau kev ntawm gutter rwb thaiv tsev yog:
(1)Cov khoom siv hollow cov ntaub ntawv siv tsis siv cov ntaub ntawv ib leeg xwb, thiab cov pa hluav taws xob txheej txheem siv;
(2)Muab cov txheej txheej ntawm ib txheej txheej txheej rau saum npoo ntawm ib-txheej khoom siv ua haujlwm.
2. Rau phab ntsa tiab tiab
Thaum lub thickness ntawm phab ntsa tsis loj, sab nraud tshav kub dissipation ntawm cov av av txheej ntawm lub hauv paus kuj tseem yog cov channel tseem ceeb rau kev ua kom sov sov. Yog li ntawd, hauv kev tsim kho ntawm tsev cog khoom txheej, cov rwb thaiv tsev txheej yog nteg sab nraud lub hauv paus lossis 3cm tuab polyurethane ua npuas dej, thiab lwm yam). Nws kuj tseem siv tau los khawb 0.5-1.0m dav thiab 0.5m dav txias trench raws li lub hauv paus thiab sau nws nrog kev poob hauv av kub.
3. Rau cov kab hlau ntub thiab cua txhuam lub qhov
Ua txoj haujlwm zoo ntawm kev sib khi tsim ntawm qhov kev sib tshuam lossis lub caij ntuj no npog thaiv.
Yog tias koj xav tau cov ntaub ntawv ntxiv, thov koj xav hu rau Chengfei tsev xog paj. Peb tsom mus rau tsev cog khoom tsim thiab tsim khoom txhua lub sijhawm. Sim ua kom cov tsev ntsuab rov qab los lawv cov ntsiab lus thiab tsim tus nqi rau kev ua liaj ua teb.
