Thermal conductivity of insulation ke eng?

Thermal conductivity, eo hape e tsejoang e le thermal conductivity, ke ntlha e ka sehloohong e khethollang phello ea ho pata ha mehaho.E lekanya bokhoni ba thepa ea ho tsamaisa mocheso 'me ke taba ea bohlokoa ha u khetha thepa ea ho kenya letsoho mohahong.Ho utloisisa mokhoa oa ho futhumatsa mocheso oa ho kenya letsoho ho ka thusa beng ba matlo le lihahi ho etsa liqeto tse nang le tsebo mabapi le mofuta o motle oa ho futhumatsa o ka sebelisoang malapeng a bona.

Thermal conductivity ke tekanyo ea bokhoni ba thepa ho tsamaisa mocheso.E hlahisoa ka li-watts ka mithara ka tekanyo ea Celsius (W/mK) 'me e bonahatsa sekhahla seo mocheso o fetisoang ka sona.Lisebelisoa tse nang le mocheso o tlase oa mocheso ke li-insulator tse molemo hobane li tsamaisa mocheso ka mokhoa o fokolang.

Ha ho tluoa tabeng ea ho kenya mocheso, mocheso oa mocheso o phetha karolo ea bohlokoa ho lekanyetsa bokhoni ba thepa ea ho boloka mohaho o futhumetse mariha le ho pholile lehlabula.Insulation e sebetsa ka ho tšoara lipokotho tsa moea ka har'a sebopeho sa eona, ho theha mokoallo o liehisang ho fetisoa ha mocheso.Lisebelisoa tse nang le conductivity e tlaase ea mocheso li thibela mocheso ho tsoa kapa ho kena mohahong, ho fokotsa litšenyehelo tsa matla le ho ntlafatsa boiketlo ba baahi.

Thermal conductivity ea thepa ea ho kenya letsoho e ka fapana ho latela mofuta oa thepa e sebelisoang.Ka mohlala, fiberglass le cellulose insulation li na le li-conductivity tsa mocheso tse ka bang 0.04-0.05 W / mK, ha ho kenngoa ha foam ea spray ho ka ba le conductivities ea mocheso e ka tlaase ho 0.02 W / mK.Ka lebaka la conductivity ea bona e tlaase ea mocheso, lisebelisoa tsena li nkoa e le li-insulators tse sebetsang hantle.

Ha u khetha mofuta o nepahetseng oa ho kenya mohaho bakeng sa mohaho, ke habohlokoa ho utloisisa mocheso oa mocheso oa mocheso.Lintlha tse kang boemo ba leholimo, moralo oa moaho le khetho ea motho kaofela li na le karolo ea ho khetholla thepa e ntle ka ho fetisisa ea ho kenya letsoho.Ha u khetha khetho e nepahetseng ka ho fetisisa bakeng sa moaho o itseng, ho bohlokoa ho nahana ka boleng ba R-boleng ba thepa ea insulation le conductivity ea mocheso.

Libakeng tse batang, moo litšenyehelo tsa ho futhumatsa e leng taba, ho bohlokoa ho khetha lisebelisoa tsa ho kenya letsoho tse nang le conductivity e tlase ea mocheso ho fokotsa tahlehelo ea mocheso.Libakeng tse futhumetseng, sepheo se ka 'na sa e-ba ho thibela ho eketseha ha mocheso, kahoo ho kenya letsoho ka conductivity e tlaase ea mocheso ho bohlokoa ka ho lekana.Ka ho utloisisa conductivity ea mocheso oa ho pata, beng ba matlo le lihahi ba ka khetha mokhoa o sebetsang ka ho fetisisa oa ho kenya letsoho ho latela litlhoko tsa bona tse khethehileng.

Ka kakaretso, conductivity ea mocheso oa thepa e sireletsang ke ntlha ea bohlokoa ho khethollang bokhoni ba thepa ea ho hanyetsa mocheso oa mocheso.Lisebelisoa tse nang le mocheso o tlase oa mocheso ke li-insulators tse molemo, tse thusang ho ntlafatsa matla a matla a mohaho le boiketlo.Ka ho utloisisa conductivity ea mocheso oa ho pata le bohlokoa ba eona, beng ba matlo le lihahi ba ka etsa liqeto tse nang le tsebo mabapi le mofuta o motle ka ho fetisisa oa ho futhumatsa o ka sebelisoang malapeng a bona.
