Lub tshuab nqus tsev insulated yog siv rau kev sib txuas ntawm cov dej kub tsawg, thiab muaj cov nyhuv tshwj xeeb ntawm cov dej txias txias. Lub rwb thaiv tsev ntawm lub tshuab nqus tsev insulated yeeb yog tus txheeb ze. Piv nrog cov tshuaj insulated ib txwm muaj, lub tshuab nqus tsev ua haujlwm nrawm dua.

Yuav ua li cas los txiav txim siab seb lub nqus plua plav insulated puas yog qhov ua haujlwm tau zoo thaum nws siv ntev? Feem ntau yog los ntawm kev saib seb puas yog sab nraud phab ntsa ntawm VI yeeb tshwm sim tshwm sim ntawm dej thiab te. (Yog lub tshuab nqus tsev rwb thaiv tsev yog nruab lub ntsuas cua ntawm cov dej ntawm lub Vi cov yeeb nkab yog tias lub tshuab nqus dej yog tias lub tshuab nqus hluav taws xob tsis txaus, thiab Nws tsis tuaj yeem txuas ntxiv ua si lub luag haujlwm insulated.

Cov ua rau ntawm qhov tshwm sim ntawm cov dej hws dej thiab te

Muaj feem ntau ob lub teeb meem ntawm frosting,

Siv tshuab luam ntawv lossis vuag ntau ntxiv, ua rau muaj kev txo qis hauv lub tshuab nqus tsev.

● Lub ntuj tso roj tawm ntawm cov khoom ua rau kom txo hauv lub tshuab nqus tsev.

Nqus tshuab nozzle lossis weld txeej, uas yog kom tsis muaj cov khoom lag luam tsis muaj. Cov neeg tsim khoom tsis muaj cov kws soj ntsuam cov cuab yeej kuaj thiab tshuaj xyuas cov khoom siv hauv kev kuaj xyuas. Lub tshuab nqus tsev rwb thaiv tsev ua los ntawm cov tuam ntxhab zoo feem ntau tsis muaj teeb meem hauv qhov no.

Cov khoom siv tso tawm roj, uas yog unavoidable. Nyob rau hauv kev siv VI vias, cov khoom siv tshuaj insulated yuav txuas ntxiv tso roj hauv lub tshuab nqus tsev interlle ntawm lub tshuab nqus tsev. Yog li VI yeeb muaj lub neej pabcuam. When the vacuum degree drops to the state that cannot be adiabatic, the VI pipe can be vacuumed for the second time through the pumping unit to improve the vacuum degree and restore its insulated effect.

Frosting tsis txaus nqus tsev, thiab yog li dej?

Thaum qhov tshwm sim ntawm cov dej tsim muaj tshwm sim hauv lub tshuab nqus tsev adiagatic cov raj, lub nqus tsev nqus dej tsis txaus.

Ua ntej tshaj plaws, cov nyhuv insulated ntawm VI yeeb yog tus txheeb ze. Thaum lub dav hlau sab nraud ntawm lub Vi cov yeeb nkab nyob hauv qab huab cua sov nyob rau hauv 3 kelvin (sib npaug ntawm VI cov yeeb nkab yog suav tias yog siv tau. Therefore, if the environmental humidity is relatively high at that time, when the temperature of VI pipe is less than 3 Kelvin from the environment, the water condensation phenomenon will also occur. Cov ntaub ntawv tshwj xeeb muaj nyob hauv daim duab hauv qab no.
