Menene thermal conductivity na rufi?

Ƙunƙarar zafin jiki, wanda kuma aka sani da ƙaddamar da zafin jiki, shine maɓalli mai mahimmanci wanda ke ƙayyade tasirin rufin gine-gine.Yana auna ikon abu don gudanar da zafi kuma yana da mahimmancin la'akari lokacin zabar kayan don rufin gini.Fahimtar ma'aunin zafin jiki na rufi zai iya taimaka wa masu gida da magina su yanke shawara game da mafi kyawun nau'in rufin da za a yi amfani da su a cikin gidajensu.

Ƙarƙashin zafi shine ma'aunin ƙarfin abu don gudanar da zafi.An bayyana shi a cikin watts a kowace mita a kowace digiri Celsius (W / mK) kuma yana nuna ƙimar da ake canjawa zafi ta hanyar abu.Abubuwan da ke da ƙananan haɓakar thermal sune mafi kyawun insulators saboda suna gudanar da zafi ƙasa da inganci.

Idan ya zo ga zafin zafi, zafin zafin jiki yana taka muhimmiyar rawa wajen tantance ikon abu don kiyaye ginin gini a cikin hunturu da sanyi a lokacin rani.Insulation yana aiki ta hanyar tarko aljihun iska a cikin tsarinsa, yana haifar da shinge wanda ke jinkirta canja wurin zafi.Kayayyakin da ke da ƙarancin ƙarancin zafin jiki yadda ya kamata suna hana zafi daga tserewa ko shigar da gini, rage farashin makamashi da haɓaka ta'aziyyar mazaunin.

Ƙunƙarar zafi na kayan rufewa na iya bambanta dangane da nau'in kayan da aka yi amfani da su.Misali, gilashin fiberglass da insulation cellulose suna da halayen thermal na kusan 0.04-0.05 W/mK, yayin da feshin kumfa zai iya samun tasirin thermal kamar ƙasa da 0.02 W/mK.Saboda ƙarancin ƙarfin wutar lantarki, waɗannan kayan ana ɗaukar insulators masu inganci.

Lokacin zabar nau'in rufin da ya dace don ginin, yana da mahimmanci a fahimci yanayin yanayin zafi na rufin.Abubuwa kamar yanayin yanayi, ƙirar gini da fifikon sirri duk suna taka rawa wajen tantance mafi kyawun kayan rufewa.Lokacin zabar zaɓin da ya fi dacewa don ƙayyadaddun gini, yana da mahimmanci a yi la'akari da ƙimar R-ƙirar kayan rufewa da haɓakar thermal.

A cikin yanayin sanyi, inda farashin dumama ke da matsala, yana da mahimmanci a zaɓi kayan rufewa tare da ƙarancin ƙarfin zafi don rage asarar zafi.A cikin yanayi mai zafi, mai da hankali zai iya kasancewa don hana samun zafi, don haka rufi tare da ƙananan ƙarancin zafi yana da mahimmanci daidai.Ta hanyar fahimtar ma'auni na thermal conductivity na rufi, masu gida da magina za su iya zaɓar mafi tasiri mai mahimmanci bisa ga takamaiman bukatun su.
