German Technological Core: Kev sib xyaw ua ke zoo tshaj plaws ntawm Gravel thiab PCM
Kev tshawb fawb pom zoo los ntawm pab pawg tshawb fawb German tau tsim lub hauv paus rau PCM-infusedpob zeb. Cov txheej txheem tseem ceeb suav nrog kev siv cov pob zeb ntuj ntxeem tau (xws li basalt gravel nrog 30%-40% porosity) ua tus nqa khoom, uas octadecane (ib qho khoom siv-kua theem hloov tshuaj) yog txhaj ntawm lub tshuab nqus tsev perfusion los tsim cov khoom siv hluav taws xob sib xyaw. Octadecane lub sijhawm hloov pauv kub yog tswj hwm ntawm 24℃- qhov tseem ceeb rau tib neeg thermal kev nplij siab. Thaum ambient kub tshaj 24 degree, octadecane absorbs tshav kub thiab melts los ntawm cov khoom rau cov kua; Thaum qis dua 24 degree, nws tso cov cua sov thiab ua kom khov, tsim "kub buffering" los ntawm cov theem hloov.
Kev ntsuam xyuas qhia tau tias cov khoom sib xyaw no ua tiav qhov thermal cia ceev ntawm 180kJ / kg, 5-8 npaug ntawm cov pob zeb zoo tib yam. Qhov tseem ceeb, cov pob zeb cov pob zeb ntxeem tau muab qhov ruaj khov "ntev" rau PCM, tiv thaiv kev xau-ib qho teeb meem nrog cov ntaub ntawv hloov pauv ntshiab-txuas nws lub neej kev pab mus rau ntau tshaj 20 xyoo, txuam nrog kev ua neej nyob ntawm lub tsev.
Daim ntawv thov Scenario: Lub zog kiv puag ncig los ntawm phab ntsa mus rau Passive Houses
Hauv kev tsim cov ntawv thov, PCM-infused gravel qhia lub zog tseem ceeb- txuag cov teebmeem. Thaum siv los ua phab ntsa txhaws, nws ruaj khov nyob hauv tsev kub hloov pauv los ntawm nws qhov nqus cua sov- tawm lub voj voog. Cov ntaub ntawv teb los ntawm Stuttgart passive lub tsev project qhia: sab nrauv phab ntsa uas muaj cov khoom siv no txo qhov siab tshaj plaws lub caij ntuj sov sab hauv tsev los ntawm 4-6℃thiab nce lub caij ntuj no yam tsawg kawg nkaus los ntawm 3-5 degree, ncaj qha txiav cua txias zog noj los ntawm 35%.
Nws txoj hauv kev ua haujlwm yog nyob rau hauv dynamically txuam ib puag ncig loads: thaum nruab hnub, hnub ci heats phab ntsa, thiab cov khoom absorbs thiab khaws cov cua sov; thaum hmo ntuj, raws li qhov kub thiab txias poob, nws tso cua sov kom tswj tau qhov kub ntawm chav tsev, txo kev cia siab rau cov cua txias lossis cua sov. Tus qauv "passive zog cia" no yog tshwj xeeb tshaj yog zoo nyob rau hauv temperate regions. Pilot tej yaam num nyob rau hauv lub teb chaws Yelemees thiab Tuam Tshoj tus Yangtze River phiab tau ua tiav tshaj 30% txhua xyoo kev txuag hluav taws xob hauv tsev.
Nqe Zoo: Scaling Phase Hloov Technology
Piv nrog rau cov ntaub ntawv hloov pauv ib txwm muaj, PCM-infused gravel muaj qhov "qhov loj me-txo" tus nqi kom zoo dua. Tam sim no loj- nplai cov nqi tsim khoom yog kwv yees li ¥ 85 / m³, tsuas yog 40% ntawm cov kab ke hloov pauv cov ntaub ntawv microcapsule (uas raug nqi ib ncig ¥ 210 / m³). Tus nqi txo yog los ntawm: dav muaj ntuj gravel nrog cov nqi mining tsawg; yooj yim nqus perfusion txheej txheem uas tsis txhob complex tshuaj synthesis; thiab octadecane muab tau los ntawm cov nroj tsuag waxes nrog controllable raw khoom nqi.
Los ntawm lub neej voj voog txoj kev xav, qhov txiaj ntsig ntawm tus nqi no tseem ceeb dua. Rau qhov chaw nyob 100㎡, thawj zaug peev hauv PCM-infused gravel wall filling tsuas yog nce los ntawm ~ ¥ 5,000, tab sis kev txuag hluav taws xob txhua xyoo ncav cuag ¥ 800-1,200, nrog them rov qab hauv 5-6 xyoo. Tshaj li cov khoom siv lub neej 20 xyoo, tag nrho cov txiaj ntsig txuag hluav taws xob ncav cuag ¥ 16,000-24,000, tshem tawm kev lag luam teeb meem rau kev txhawb nqa tsev ntsuab loj.
