1.6 Umgaqo-siseko Intshayelelo

1.6.1 Inkcazo kunye neyunithi yokumelana ne-thermal

Ukumelana ne-Thermal: ubushushu obomileyo buhamba kwindawo ethile xa i-textile ikwiqondo lokushisa elizinzileyo.

Iyunithi yokumelana ne-thermal i-Rct ikwi-Kelvin ngewathi nganye yesikwere semitha (m²·K/W).

Xa ufumanisa ukuxhathisa kwe-thermal, isampuli ihlanganiswe kwibhodi yokuvavanya ukufudumeza kombane, ibhodi yokuvavanya kunye nebhodi yokukhusela ejikelezileyo kunye neplate ephantsi igcinwe kwiqondo lokushisa elifanayo (elifana ne-35 ℃) ngokulawula ukushisa kombane, kunye nobushushu. Uluvo ludlulisela idatha kwinkqubo yokulawula ukugcina ubushushu obungaguqukiyo, ukuze ubushushu besampulu yesampulu buchithelwe phezulu kuphela (kwicala lesampulu), kwaye zonke ezinye izikhokelo zi-isothermal, ngaphandle kokutshintshiselana kwamandla.Kwi-15mm kumphezulu ongaphezulu kumbindi wesampulu, ubushushu bolawulo yi-20°C, ukufuma okunxulumeneyo yi-65%, kunye nesantya somoya esithe tye yi-1m/s.Xa iimeko zokuvavanya zizinzile, inkqubo iya kugqiba ngokuzenzekelayo amandla okufudumala afunekayo kwibhodi yokuvavanya ukugcina ukushisa okungapheliyo.

Ixabiso lokumelana ne-thermal lilingana nokumelana ne-thermal yesampuli (i-15mm yomoya, i-test plate, isampuli) isuse ukuchasana kwe-thermal ye-plate engenanto (i-15mm yomoya, i-test plate).

Isixhobo sibala ngokuzenzekelayo: ukumelana ne-thermal, i-coefficient yokudlulisa ukushisa, ixabiso le-Clo kunye nesantya sokugcina ukushisa

Phawula: (Ngenxa yokuba idatha yokuphindaphinda kwesixhobo ihambelana kakhulu, ukuchasana kwe-thermal yebhodi engenanto kuphela kufuneka kwenziwe kanye emva kweenyanga ezintathu okanye isiqingatha sonyaka).

1.6.2 Inkcazo kunye neyunithi yokumelana nokufuma

Ukumelana nokufuma: Ukuhamba kobushushu bomphunga kwindawo ethile phantsi kwemeko yoxinzelelo lomoya ozinzileyo wamanzi.

Iyunithi yokumelana nokufuma i-Ret ikwi-Pascal ngewathi nganye yesikwere semitha (m²·Pa/W).

Ipleyiti yokuvavanya kunye nepleyiti yokukhusela zombini iipleyiti ezikhethekileyo zetsimbi, ezigqunywe ngefilimu encinci (enokuthi ifake kuphela umphunga wamanzi kodwa ingabi namanzi angamanzi).Ngaphantsi kokufudumala kombane, ubushushu bamanzi adibeneyo anikezelwe yinkqubo yokubonelela ngamanzi aphakama kwixabiso elimiselweyo (elifana ne-35 ℃).Ibhodi yokuvavanya kunye nebhodi yayo yokukhusela ejikelezileyo kunye neplate ephantsi zonke zigcinwe kwiqondo lokushisa elifanayo (elifana ne-35 ° C) ngokulawulwa kokushisa kombane, kwaye inzwa yokushisa idlulisela idatha kwinkqubo yokulawula ukugcina ukushisa okungapheliyo.Ke ngoko, amandla obushushu bomphunga wamanzi ebhodi yesampulu anokuba phezulu kuphela (kwicala lesampulu).Akukho mphunga wamanzi kunye nokutshintshana kobushushu kwezinye iindawo,

ibhodi yokuvavanya kunye nebhodi yokukhusela ejikelezileyo kunye nesitya esisezantsi zonke zigcinwa kwiqondo lokushisa elifanayo (elifana ne-35 ° C) ngokufudumeza kombane, kwaye inzwa yokushisa idlulisela idatha kwinkqubo yokulawula ukugcina ukushisa okungapheliyo.Amandla obushushu bomphunga wamanzi epleyiti yesampulu anokuchithwa phezulu kuphela (kwicala lomzekelo).Akukho tshintshiselwano lwamandla obushushu bomphunga wamanzi kwamanye amacala.Iqondo lobushushu kwi-15mm ngaphezu kwesampulu ilawulwa kwi-35℃, ukufuma okunxulumeneyo yi-40%, kunye nesantya somoya oxwesileyo yi-1m/s.Umphezulu ongezantsi wefilimu unoxinzelelo lwamanzi olugcweleyo lwe-5620 Pa kwi-35 ℃, kunye nomgangatho ophezulu wesampuli unoxinzelelo lwamanzi lwe-2250 Pa kwi-35 ℃ kunye nokufuma kwe-40%.Emva kokuba iimeko zokuvavanya zizinzile, inkqubo iya kugqiba ngokuzenzekelayo amandla okufudumala afunekayo kwibhodi yokuvavanya ukugcina ukushisa okungapheliyo.

Ixabiso lokumelana nomswakama lilingana nokumelana nomswakama wesampulu (umoya we-15mm, ibhodi yokuvavanya, isampuli) thabatha ukunyanzeliswa komswakama webhodi engenanto (15mm umoya, ibhodi yokuvavanya).

Isixhobo sibala ngokuzenzekelayo: ukuxhathisa ukufuma, isalathisi sokungena komswakama, kunye nokunyameka komswakama.

Phawula: (Ngenxa yokuba idatha yokuphindaphinda kwesixhobo ihambelana kakhulu, ukuchasana kwe-thermal yebhodi engenanto kuphela kufuneka kwenziwe kanye emva kweenyanga ezintathu okanye isiqingatha sonyaka).
