Kev nyab xeeb ntawm Insulated iav
- Mar 01, 2018 -

Vim tias cov dej thev ntim hauv lub pas dej tau tso tawm tau cov dej ua kua dej, cov pa yog qhuav, thaum ntsuas kub, lub sab hauv ntawm lub khob iav yuav tsis ua rau qhov tshwm sim, tib lub sij hawm, sab nraud ntawm lub iav insulating dew point kuj yuav nce. Yog tias qhov cua nruag sab nraud yog 5m / s, sab hauv tsev txias 20 ℃, txhuam cov cua nrig yog 60%, 5 hli iav ntawm qhov chaw kub sab hauv 8 hli ℃, thiab 16 hli (5 + 6 + 5) qhov kub thiab txias yog 2 ℃ thaum lub qhov hnyuv, 27mm (5 + 6 + 5 + 6 + 5 thooj hauv cov thawv rau sab nrauv ntawm 11 ℃ los pib ua dejnum.

Vim tias cov iav insulating muaj kev sib xyaw ua kom sov zoo, qhov kub qhov txawv ntawm ob sab ntawm cov iav loj loj, kuj tseem tuaj yeem txo cov nyhuv ntawm cov hluav taws xob txias; Thaum lub qhov cub sab nraud yog 10 ℃, qhov kub nyob rau sab xub ntiag ntawm lub qhov rais sab hauv--2 ℃ thiab qhov kub ua ntej qhov iav qhov rai iav yog 13 ℃; Nyob rau tib lub tsev hauv tsev, thaum lub qhov cub kub sab nraud yog 8 ℃ thiab sab hauv tsev kub yog 20 ℃, Qhov 3mm ntau Ib qho txheej txheem dej ntu ib qho chaw txias qhov chaw 67.4% ntawm qhov chaw hauv tsev, thiab ob lub iav insulating (3 + 6 + 3 ) yog 13.4%.

Kev siv insulating iav, tuaj yeem ua kom muaj kev ruaj ntseg ntawm iav, siv tib lub thickness ntawm thawj daim iav, insulating iav yog 1.5 npaug zaus zaug lub zog ntawm qhov dog dig monolithic iav.
