1.6 Mfundo Yoyambira

1.6.1 Tanthauzo ndi unit of thermal resistance

Kutentha kwa kutentha: kutentha kowuma kumadutsa m'dera linalake pamene nsalu ili mu kutentha kokhazikika.

Thermal resistance unit Rct ili mu Kelvin pa watt pa lalikulu mita (m²· K/W).

Mukazindikira kukana kwamafuta, chitsanzocho chimakutidwa pa bolodi yoyeserera yamagetsi, bolodi yoyeserera ndi bolodi lozungulira lozungulira ndi mbale yapansi zimasungidwa pa kutentha komweko (monga 35 ℃) ndi kuwongolera kwamagetsi, komanso kutentha. sensa imatumiza deta ku dongosolo lolamulira kuti likhalebe kutentha kosalekeza, kotero kuti kutentha kwa mbale yachitsanzo kungathe kutayidwa m'mwamba (motsatira chitsanzo), ndi njira zina zonse ndi isothermal, popanda kusinthanitsa mphamvu. Pa 15mm pamwamba pakatikati pa chitsanzo, kutentha kwapakati ndi 20 ° C, chinyezi chapafupi ndi 65%, ndi mphepo yopingasa ndi 1m / s. Pamene mayesero ali okhazikika, dongosololi lidzadziwiratu mphamvu yotenthetsera yomwe ikufunika kuti gulu loyesera likhalebe kutentha kosalekeza.

Mtengo wotsutsa kutentha ndi wofanana ndi kukana kwa kutentha kwa chitsanzo (mpweya wa 15mm, mbale yoyesera, chitsanzo) kuchotsa kukana kwa kutentha kwa mbale yopanda kanthu (mpweya wa 15mm, mbale yoyesera).

Chidacho chimawerengera zokha: kukana kwamafuta, kutengera kutentha kwapakati, mtengo wa Clo ndi kuchuluka kwa kusunga kutentha

Zindikirani: (Chifukwa chakuti deta yobwerezabwereza ya chipangizocho ndi yofanana kwambiri, kukana kwa kutentha kwa bolodi lopanda kanthu kumangofunika kuchitidwa kamodzi pa miyezi itatu kapena theka la chaka).

Zindikirani:(Chofunika kwambiri: pa kutentha kwa chipinda cha 21 ℃, chinyezi chachibale ≤50%, mpweya 10cm / s (palibe mphepo), woyesera amakhala chete, ndipo metabolism yake yoyambira ndi 58.15 W/m2 (50kcal/m²·h), khalani omasuka ndikusunga kutentha kwapakati pa thupi pa 33 ℃, kufunika kwa zovala zomwe amavala panthawiyi ndi 1 Clo value (1 CLO=0.155℃·m²/W)

1.6.2 Tanthauzo ndi gawo la kukana chinyezi

Kulimbana ndi chinyezi: kutentha kwa mpweya kupyola m'dera linalake pansi pa chikhalidwe cha mpweya wokhazikika wa madzi.

Chinyezi chokana Ret chili ku Pascal pa watt pa lalikulu mita (m²· Pa/W).

Mbale yoyesera ndi mbale yotetezera zonse ndizitsulo zapadera za porous, zomwe zimakutidwa ndi filimu yopyapyala (yomwe imatha kulowetsa nthunzi yamadzi koma osati madzi amadzimadzi). Pansi pa kutentha kwamagetsi, kutentha kwa madzi osungunuka operekedwa ndi madzi opangira madzi kumakwera kufika pamtengo wokhazikitsidwa (monga 35 ℃). Bolodi loyesera ndi bolodi lotetezera lozungulira ndi mbale yapansi zonse zimasungidwa kutentha komweko (monga 35 ° C) ndi magetsi otenthetsera kutentha, ndipo sensa ya kutentha imatumiza deta ku dongosolo lolamulira kuti likhalebe kutentha kosalekeza. Choncho, mphamvu ya kutentha kwa nthunzi yamadzi ya bolodi lachitsanzo ingakhale yokwera pamwamba (motsatira chitsanzo). Palibe nthunzi wamadzi ndi kusinthanitsa kutentha mbali zina,

bolodi loyesera ndi bolodi lake lotetezera lozungulira ndi mbale ya pansi zonse zimasungidwa pa kutentha kofanana (monga 35 ° C) pogwiritsa ntchito kutentha kwa magetsi, ndipo sensa ya kutentha imatumiza deta ku dongosolo lolamulira kuti likhalebe kutentha kosalekeza. Mphamvu ya kutentha kwa nthunzi yamadzi ya mbale yachitsanzo ingathe kutayidwa m'mwamba (motsatira chitsanzo). Palibe kusinthana kwa mphamvu ya nthunzi yamadzi kumadera ena. Kutentha kwa 15mm pamwamba pa chitsanzo kumayendetsedwa pa 35 ℃, chinyezi chapafupi ndi 40%, ndi mphepo yopingasa ndi 1m / s. Pamunsi pa filimuyi ali ndi mphamvu zodzaza madzi za 5620 Pa pa 35 ℃, ndipo pamwamba pa chitsanzocho chimakhala ndi mphamvu yamadzi ya 2250 Pa pa 35 ℃ ndi chinyezi chachibale cha 40%. Pambuyo poyesa kukhazikika, dongosololi lidzadziwikiratu mphamvu yotentha yofunikira kuti bolodi loyesa likhalebe kutentha kosalekeza.

Mtengo wotsutsa chinyezi ndi wofanana ndi kukana kwa chinyezi cha chitsanzo (mpweya wa 15mm, bolodi loyesera, chitsanzo) kuchotsa kukana kwa chinyezi cha bolodi lopanda kanthu (mpweya 15mm, bolodi loyesera).

Chidacho chimawerengetsera zokha: kukana chinyezi, chilozera cha chinyezi, komanso kutulutsa chinyezi.

Zindikirani: (Chifukwa chakuti deta yobwerezabwereza ya chipangizocho ndi yofanana kwambiri, kukana kwa kutentha kwa bolodi lopanda kanthu kumangofunika kuchitidwa kamodzi pa miyezi itatu kapena theka la chaka).

1.7 Kapangidwe ka zida

Chidacho chimapangidwa ndi magawo atatu: makina akuluakulu, dongosolo la microclimate, kuwonetsera ndi kulamulira.

1.7.1Thupi lalikulu lili ndi mbale yachitsanzo, mbale yoteteza, ndi mbale yapansi. Ndipo mbale iliyonse yotenthetsera imasiyanitsidwa ndi zinthu zotetezera kutentha kuti zitsimikizire kuti palibe kutentha kwapakati pakati pawo. Pofuna kuteteza chitsanzo kuchokera kumlengalenga wozungulira, chivundikiro cha microclimate chimayikidwa. Pali chitseko chagalasi chowoneka bwino pamwamba, ndipo sensa ya kutentha ndi chinyezi cha chipinda choyesera imayikidwa pachivundikirocho.

1.7.2 Njira yowonetsera ndi kupewa

Chidacho chimatengera mawonekedwe ophatikizika a weinview touch display, ndikuwongolera dongosolo la microclimate ndi woyesa mayeso kuti agwire ntchito ndikuyimitsa pogwira mabatani omwe akuwonetsedwa pazenera, zowongolera zolowera, ndi data yoyeserera ya mayeso ndi zotsatira.

1.8 Makhalidwe a zida

1.8.1 Cholakwika chobwerezabwereza chochepa

Gawo lapakati la YYT255 makina owongolera kutentha ndi chipangizo chapadera chomwe chimafufuzidwa paokha ndikupangidwa. Mwachidziwitso, zimachotsa kusakhazikika kwa zotsatira zoyesa zomwe zimayambitsidwa ndi inertia yotentha. Ukadaulo uwu umapangitsa cholakwika cha mayeso obwereza kukhala ochepa kwambiri kuposa miyezo yoyenera kunyumba ndi kunja. Zida zambiri zoyesera "kutengera kutentha" zimakhala ndi zolakwika zobwerezabwereza pafupifupi ± 5%, ndipo kampani yathu yafika ± 2%. Zinganenedwe kuti zathetsa vuto la nthawi yayitali lapadziko lonse la zolakwika zazikulu zobwerezabwereza mu zida zotenthetsera kutentha ndikufikira pamlingo wapamwamba wapadziko lonse. .

1.8.2 Mapangidwe ang'onoang'ono ndi kukhulupirika kolimba

YYT255 ndi chipangizo chomwe chimagwirizanitsa wolandirayo ndi microclimate. Itha kugwiritsidwa ntchito paokha popanda zida zilizonse zakunja. Imasinthasintha ndi chilengedwe ndipo imapangidwa mwapadera kuti ichepetse kugwiritsa ntchito.

1.8.3 Kuwonetsa zenizeni zenizeni za "kukana kutentha ndi chinyezi" mfundo

Chitsanzocho chikatenthedwa mpaka kumapeto, njira yonse yokhazikika ya "kutentha kwa kutentha ndi chinyezi" yokhazikika ikhoza kuwonetsedwa mu nthawi yeniyeni. Izi zimathetsa vuto la nthawi yayitali yoyesera kukana kutentha ndi chinyezi komanso kulephera kumvetsetsa ndondomeko yonseyi.

1.8.4 Kuyerekeza kwambiri pakhungu-kutuluka thukuta

Chidacho chimakhala ndi mawonekedwe apamwamba a khungu la munthu (lobisika) thukuta, lomwe ndi losiyana ndi bolodi loyesera ndi mabowo ochepa chabe. Imakwaniritsa kuthamanga kwa nthunzi wamadzi wofanana kulikonse pa bolodi loyesera, ndipo malo oyesera ogwira ntchito ndi olondola, kotero kuti kuyeza "kukana chinyezi" kuli pafupi phindu lenileni.

1.8.5 Multi-point palokha ma calibration

Chifukwa cha kuchuluka kwakukulu kwa kuyezetsa kwa kutentha ndi chinyezi, kuwongolera kodziyimira pawokha kwamitundu yambiri kumatha kuwongolera bwino cholakwika chomwe chimabwera chifukwa cha kusagwirizana ndikuwonetsetsa kuti mayesowo ndi olondola.

1.8.6 Kutentha kwa Microclimate ndi chinyezi zimagwirizana ndi malo olamulira

Poyerekeza ndi zida zofananira, kutengera kutentha kwa microclimate ndi chinyezi chogwirizana ndi malo olamulira okhazikika kumagwirizana kwambiri ndi "njira yoyenera", ndipo zofunikira pakuwongolera microclimate ndizokwera.

Malo athu okhala ndi zida komanso zogwirira ntchito zapamwamba kwambiri pamagawo onse opanga zimatithandiza kutsimikizira kukwaniritsidwa kwamakasitomala ku Factory Molunjika China Water-Vapor Permeability Index Tester Dw259A, Timachita zonse zomwe tingathe kuti tipereke ntchito yabwino kwa ogula ambiri komanso amalonda.
Factory mwachindunji kuperekaChina Kuthukuta Kutetezedwa Hotplate, Water-Vapor Permeability Index, fakitale yathu ili ndi malo okwanira 10000 masikweya mita, zomwe zimatipangitsa kukhala okhoza kukwaniritsa kupanga ndi kugulitsa mayankho ambiri amagalimoto. Ubwino wathu ndi gulu lathunthu, apamwamba kwambiri komanso mtengo wampikisano! Kutengera ndi izi, katundu wathu amapindula kwambiri kunyumba ndi kunja.
