The ho hanyetsa phetiso mocheso. R-boleng

Mocheso phetiso walling - ke tshebetso rarahaneng amang cavity, conduction le mahlaseli. kaofela ha bona ba tla 'moho le predominance ea mong oa bona. Li sireletsang serameng thepa terata merero, tse a bonahatsa ka ho hanyetsa mocheso seng, lokela ho iphaphatha le dikhoutu moaho.

Ka moea e fanana le walling

Kahong ea beha ditlhoko taolo bakeng sa boholo ba ka mocheso ts'ebetsong ka leboteng le ka e ho hlalosa Botenya ba lona. E mong oa entsprechen bakeng bala ke mocheso phapang hare le ka ntle kamoreng. Ho nka e le motheo oa nako e batang ea selemo. paramethara mong ke coefficient la mocheso phetiso K - mocheso chelete a tšoaetsanoang ka ka 1 bobeli ka e leng sebaka se ea 1 limithara ^2, le phapang ea ka ntle 'me ka hare tikoloho ya mocheso ka 1 ° C. The K boleng itšetlehile ka thepa ea lintho tse bonahalang. Ha e ntse e eketsa fokotsa thepa mocheso-e sireletsoe ea leboteng. Ho phaella moo, chill ka kamoreng tla phunyeletse ka tlase, haeba ho ke ke ho feta e botenya ba terata e.

Cavity le mahlaseli a ka hare le ka ntle hape ama mocheso ke tahlehelo ho tswa ka tlung. Ka hona, ka libeteri ho hlomamisa marako bonahatsa e hlahang lifiliming tsa aluminium foil. tšireletso e joalo e ile a boela a ka hare ho mekhabisong ventilated ka ntle.

Mocheso phetiso ka marako a ntlo

Marako bokantle etsa ka ho fetisisa tsa sebaka seo la ntlo le ka ba le tahlehelo ya eneji, fihle 35-45%. Thepa ea mohaho etsang le mehaho e ea kenyelletsa, na tšireletso ea fapaneng le a batang. Ho na le se tlaase-tlaase mogote conductivity ea moea. Ka hona, le thepa porous na le melao ea boitšoaro e tlaase-tlaase tsa coefficients mocheso phetiso. Mohlala, litene kaho K = 0,81 W / (limithara ² · ^C), ka konkreiti s K = 2,04 W / (limithara ² · ^C), ka plywood K = 0,18 W / (limithara ² · ^C.) le polystyrene lipoleiti ka K = 0,038 w / (limithara ² · ° ^C).

dipalelo The sebelisa karabo ya go arola ba coefficient K, - R-boleng. Ke boleng boetse maemong 'me ha lia lokela ho tlase e itseng boleng reriloeng pele, kaha e itšetlehile ka litšenyehelo tsa futhumatsang le maemo lula ka jareteng eo.

Ka K Ntlha e ama dikahare mongobo walling. Ka lintho tse bonahalang tse e tala metsi a displaces moea pores, 'me conductivity lona mogote ke makhetlo a 20 e phahameng. Ka lebaka leo, mpefala mocheso e sireletsoe thepa ea terata e. Metsi setene leboteng fetisetsa mocheso 30% ho feta e omme. Ka hona, le kene lekokong le marulelo a matlo a leka ho thepa clad oo metsi e sa bolokoa.

Mocheso ke tahlehelo ka marako le openings ka manonyeletso ke haholo itšetlehile ka moea. Tshehetso dibopeho - breathable le moea o feta ho tloha ka ntle (khukhuneloa) le ka hare (exfiltration).

Haholo-holo e moholo tahlehelo mocheso ka marulelong malapeng one- le mekato e 'meli. Ba fihla 35%. Morao-rao li sireletsang serameng thepa lumella ho tshepahala sireletsa marulelo le siling ea tikoloho Link le bohato ba ho shoeloa mocheso ho tloha ka hare.

E le a ikemiselitse ke ho hanyetsa mocheso phetiso

Ka kutloisiso e 'meleng, mocheso phetiso ho hanyetsa ea kenyelletsa sebopeho ba tsebahala ka boemo ba thepa lona mogote li sireletsang serameng le e fumaneha karo-karolelano ea

Fokotswa ho hanyetsa phetiso mocheso

Ka liketso, dibopeho tse heterogeneous le di na le dipegelo likarolo fastening le dikarolo tse ding puisano e leng ho theha "manonyello a batang". Heterogeneity dibopeho ka haholo fokotsa ho hanyetsa mogote a phutheho. Ka hona, ho etsa hore ba bang ba karolelano boleng R ₀ ^{'bakeng sa} terata lekanang le thepa junifomo fetela sebakeng sohle. Ka mohlala, ka bo manolotsoeng tsa botenya ha marako a mohaho ba elwa hloko tahlehelo mocheso ka fensetere 'me monyako matsoapong, heke, likarolo motho ya moaho ho ya ka dipehelo ya fokotswa ho hanyetsa mogote. Ka setšoantšo bontšitsoeng ke metsu, ho conductivity mogote ea letlapa e hahiloeng ka konkreite pulls futhumatsa tsoa.

Fokotswa ho hanyetsa phetiso mocheso ke ikemiselitse ka mor'a boikemisetso ba libaka le tsohle tse ka sehloohong ya bohato ba fluxes fapaneng mocheso. Ka mor'a moo, ho latela GOST 26254-84, e balwa sebelisa moralo o balletsweng e:
