Thaum tshav kub kub rov qab nyob rau hauv Sustainable nroog

1, Tus nqi tseem ceeb: Kev siv hluav taws xob zoo hauv nroog 'Invisible Energy Storage'
Kev hloov hluav taws xob: Tag nrho cov khoom siv hluav taws xob pov tseg hauv cov nroog thoob ntiaj teb tuaj yeem npog cov kev xav tau cua sov ntawm cov tsev; Cov khib nyiab hluav taws xob los ntawm 22 EU lub teb chaws tuaj yeem ua tau raws li 50% ntawm lub zog xav tau.
Kev txo cov pa roj carbon tseem ceeb: Kev rov ua dua 1 tuj ntawm cov khoom siv hluav taws xob ≈ txo 0.2-0.3 tons ntawm CO ₂ emissions, yog lub zog tseem ceeb rau hauv nroog carbon neutrality.
Kev Lag Luam thiab Kev Ruaj Ntseg: Txo kev vam khom rau cov fossil fuels, ruaj khov tus nqi hluav taws xob hloov pauv, thiab txhim kho lub zog hluav taws xob hauv nroog.

2, Mainstream qhov chaw thiab rov qab technologies ntawm pov tseg tshav kub
1. Cov dej phwj hauv nroog / cov dej rov ua dua tshiab (qhov chaw ruaj khov thiab loj tshaj plaws)
Thaum tshav kub kub: cov dej phwj hauv tsev, cov dej siv dua tshiab, qhov kub thiab txias thoob plaws hauv lub xyoo (10-25 degree).
Tshuab: Cov dej phwj dej kub twj tso kua mis (kev rho tawm ncaj qha / tsis ncaj qha tshav kub pauv), COP tuaj yeem ncav cuag 3-5.
Daim ntawv thov: Cheeb tsam cua sov / txias, dej kub.
Case: Beijing Qinghe Reclaimed Water Plant muab cua txias thiab cua sov rau 1.6 lab square meters, txo CO ₂ emissions los ntawm kwv yees li 50000 tons ib xyoos twg; Qingdao Regenerated Water Heat Source Project muaj peev xwm cua sov txhua xyoo ntawm 5.444 lab GJ thiab txuag 28000 tons ntawm cov thee.

2. Khib cua sov los ntawm cov chaw zov me nyuam (siab-qib, tsis tu ncua)
Thaum tshav kub kub qhov chaw: Server cua sov dissipation (30-45 degree), tsis tu ncua emission thoob plaws hauv lub xyoo.
Tshuab: Ua kua txias / cua-cooled recycling + tshav kub twj tso kua mis cua sov, ua ke cua sov, hluav taws xob, thiab cua txias.
Daim Ntawv Thov: Cua sov rau cov tsev nyob ib puag ncig, tsev cog khoom, thiab tsav tsheb nqus cov tub yees.
Case: Alibaba Zhangbei Data Center muab pov tseg cua sov rau 100000 square meter tsev cog khoom, txo PUE rau 1.08.

3. Muaj cov khib nyiab cua sov (loj ntau, ntau qib)
Thaum tshav kub kub qhov chaw: circulating dej los ntawm fais fab nroj tsuag, pov tseg tshav kub los ntawm chemical / steel / petrochemical industries, flue gas, thiab chav condensation cua sov (20-300 degree).
Tshuab: Cascade tshav kub pauv, lithium bromide nqus cua sov twj tso kua mis, chav txhaj tshuaj, ntev - kev thauj mus los ntawm cov kav dej.
Daim ntawv thov: Hauv nroog centralized cua sov, kev siv rov qab siv dua.
Case: Jinan's "Hais Cua Kub rau hauv Jinan" 100 km pipeline network hloov 1.3 lab tons ntawm cov qauv thee txhua xyoo, muab 100 lab square meters; Qingdao Petrochemical pov tseg tshav kub + natural gas cascade cua sov.

4. Khib cua sov los ntawm cov chaw pej xeem hauv nroog (dispersed thiab yooj yim overlooked)
Thaum tshav kub kub qhov chaw: subway / qhov kub dissipation, khw / supermarket tso pa, underground garage, khib incineration cog flue gas.
Tshuab: Cua/Dej Dej Txias Txias Txias Txias, Me Me Tshav Kub Twj Cuam Tshuam, Cov Hluav Taws Xob Hauv Cheeb Tsam Kev Sib Koom Tes.
Cov ntaub ntawv: Singapore's Marina Bay 15km thermal zog network koom ua ke cov khib nyiab incineration, cov chaw cov ntaub ntawv, thiab subway khib nyiab cua sov los muab 2 lab square meters, txo cov cua txias zog los ntawm 40%.

5. Lub tsev thiab HVAC system khib nyiab cua sov (kawg voj voog)
Thaum tshav kub kub qhov chaw: condensation cua sov los ntawm cua txias, tso pov tseg thaum tshav kub kub, thiab pov tseg tshav kub los ntawm domestic dej kub.
Technology: Tag nrho cov tshav kub exchanger, condensation tshav kub rov qab, kub twj tso kua mis dej rhaub.
Tus nqi: Txo lub tsev lub zog siv los ntawm 20-40%.
