Umthamo wokuhambisa ukukhanya kophahla lwangaphambili
Amandla aphambili kwi-greenhouse avela elangeni. Ukwandisa umthamo wokuhambisa ukukhanya kophahla lwangaphambili kunenzuzo kwi-greenhouse ukufumana ubushushu obuninzi, kwaye kusisiseko esibalulekileyo sokuqinisekisa indawo yokushisa ye-greenhouse ebusika. Okwangoku, kukho iindlela ezintathu eziphambili zokwandisa umthamo wokuhambisa ukukhanya kunye nexesha lokufumana ukukhanya kophahla lwangaphambili lwe-greenhouse.
01 uyila i-greenhouse orientation efanelekileyo kunye ne-azimuth
Ukuqhelaniswa kwe-greenhouse kuchaphazela ukusebenza kokukhanyisa kwe-greenhouse kunye nokugcinwa kobushushu bomthamo we-greenhouse. Ngoko ke, ukuze ufumane ukugcinwa kobushushu obuninzi kwi-greenhouse, ukuqhelaniswa kweendawo zokugcina izityalo ezingalinywanga enyakatho-ntshona yeChina zijongene nezantsi. Kwi-azimuth ethile ye-greenhouse, xa ukhetha eningizimu ukuya empuma, kunenzuzo "ukubamba ilanga", kwaye ukushisa kwangaphakathi kuphakama ngokukhawuleza ekuseni; Xa kukhethwe umzantsi ukuya entshona, kuyanceda ukuba igreenhouse isebenzise ukukhanya kwemini. Isalathiso sasezantsi sisivumelwano phakathi kwezi meko zimbini zingasentla. Ngokolwazi lwe-geophysics, umhlaba ujikeleza i-360 ° ngosuku, kwaye i-azimuth yelanga ihamba malunga ne-1 ° yonke imizuzu emi-4. Ngoko ke, lonke ixesha i-azimuth ye-greenhouse ihluke nge-1 °, ixesha lokukhanya kwelanga liya kuhluka malunga nemizuzu emi-4, oko kukuthi, i-azimuth ye-greenhouse ichaphazela ixesha apho i-greenhouse ibona ukukhanya ekuseni nakusihlwa.
Xa iiyure zokukhanya zasekuseni nasemva kwemini zilingana, kwaye impuma okanye intshona ikwi-angle efanayo, i-greenhouse iya kufumana iiyure ezifanayo zokukhanya. Nangona kunjalo, kummandla osemantla we-37° isibanzi esisemantla, iqondo lobushushu liphantsi kusasa, kwaye ixesha lokugquma iqhiya lisemva kwexesha, ngelixa iqondo lobushushu liphezulu ngokwentelekiso emva kwemini nangokuhlwa, ngoko kufanelekile ukulibazisa ixesha ukuvala i-quilt ye-thermal insulation. Ngoko ke, le mimandla kufuneka ikhethe emazantsi ukuya entshona kwaye isebenzise ngokupheleleyo ukukhanya kwemini. Kwimimandla ene-30 ° ~ 35 ° ye-latitude esenyakatho, ngenxa yeemeko ezingcono zokukhanyisa ekuseni, ixesha lokugcinwa kobushushu kunye nokutyhila kwekhava kungaqhubela phambili. Ngoko ke, le mimandla kufuneka ikhethe ulwalathiso olusemazantsi-mpuma-mpuma ukuze luzabalazele ukusasazeka kwemitha yelanga yasekuseni kwi-greenhouse. Nangona kunjalo, kwindawo ye-35 ° ~ 37 ° ye-latitude emantla, kukho umehluko omncinci kwimitha yelanga kusasa nasemva kwemini, ngoko ke kungcono ukhethe indlela eya emazantsi. Nokuba kumzantsi-mpuma okanye kumzantsi-ntshona, i-engile yokutenxa ngokuqhelekileyo yi-5° ~8°, kwaye ubuninzi abuyi kuba ngaphezulu kwe-10°. Umntla-ntshona weTshayina ulele kuluhlu lwama-37°~50° isibanzi somntla, ngoko ke i-engile ye-azimuth yegreenhouse iqhelekile ukusuka emazantsi ukuya entshona. Ngenxa yoko, i-sunlight greenhouse eyenzelwe nguZhang Jingshe njl kwindawo yaseTaiyuan ikhethe ukuqhelaniswa ne-5 ° ukuya ngasentshonalanga kumzantsi, i-sunlight greenhouse eyakhiwe nguChang Meimei njl. ye-5 ° ukuya kwi-10 ° ukuya ngasentshona kumzantsi, kunye ne-sunlight greenhouse eyakhiwe ngu-Ma Zhigui njl. kumantla e-Xinjiang iye yamkela i-orientation ye-8 ° ukuya entshona ye-mazantsi.

Kwangaxeshanye, ngokweemfuno zezityalo kunye neepateni zokulima, izixhobo ezifanelekileyo kufuneka zihambelane nemigangatho, kwaye uphando oludibeneyo kunye nophuhliso, ukuveliswa kwezinto ezintsha kunye nokuthandwa kwe-ventilation, ukunciphisa ukufuma, ukugcinwa kobushushu kunye nezixhobo zokufudumeza kufuneka kukhuthazwe.
Ubunzima beendonga ezifana nesanti kunye neebhloko ezivulekileyo zisangqindilili.
Ukuba udonga lukhulu kakhulu, nangona i-insulation effect ilungile, iya kunciphisa izinga lokusetyenziswa komhlaba, ukwandisa iindleko kunye nobunzima bokwakha. Ngoko ke, kuphuhliso lwexesha elizayo, kwelinye icala, ubukhulu bodonga bunokulungiswa ngokwesayensi ngokweemeko zemozulu zendawo; Kwelinye icala, kufuneka sikhuthaze ukukhanya kunye nophuhliso lula eludongeni ngasemva, ukuze udonga ngasemva greenhouse kuphela igcina umsebenzi wogcino ubushushu, sebenzisa abaqokeleli solar kunye nezinye izixhobo endaweni yokugcina ubushushu kunye nokukhululwa eludongeni. . Abaqokeleli belanga baneempawu zokuqokelela ubushushu obuphezulu, amandla okuqokelela ubushushu obuqinileyo, ukonga amandla, ikhabhoni ephantsi njalo njalo, kwaye uninzi lwabo banokuqonda ummiselo osebenzayo kunye nolawulo, kwaye banokuqhuba ukufudumeza okujoliswe kuko ngokweemfuno zokusingqongileyo zegreenhouse. ebusuku, ngokusebenza okuphezulu kokusetyenziswa kobushushu.
Kufuneka kuphuhliswe iqhina elikhethekileyo lokugquma i-thermal.
Uphahla lwangaphambili ngumzimba ophambili wokutshatyalaliswa kobushushu kwi-greenhouse, kunye nokusebenza kwe-thermal insulation ye-quilt ye-thermal insulation ichaphazela ngokuthe ngqo indawo ye-thermal yangaphakathi. Okwangoku, indawo yobushushu be-greenhouse kwezinye iindawo ayilunganga, ngenxa yokuba i-quilt ye-thermal insulation incinci kakhulu, kwaye ukusebenza kwe-thermal insulation ye-thermal akwanelanga. Kwangaxeshanye, thermal insulation quilt isenazo iingxaki ezithile, ezifana nokungangeni kwamanzi kunye nekhono lokutyibiliza, ukuguga lula komphezulu kunye nezixhobo eziphambili, njl. iimpawu zemozulu kunye neemfuno, kunye neemveliso ezikhethekileyo zokugquma i-thermal ezilungele ukusetyenziswa kwendawo kunye nokuthandwa kufuneka ziyilwe kwaye ziphuhliswe.
