Gulu la zoziziritsa kukhosi ndi zomwe muyenera kuziganizira zikugwira ntchito

Zina zoziziritsa kukhosi ziyenera kudzazidwa ndi refrigerant pamalo ogwiritsira ntchito, ndipo kuchuluka kwa refrigerant ndi refrigerant grade ziyenera kukhala motsatira malamulo.Malipiro a refrigerant osakwanira.zidzapangitsa kuzizira kosakwanira.Kuchulukitsa kwa refrigerant sikungowonjezera ndalama zokha, komanso kungakhale ndi zotsatirapo zoyipa pakugwiritsa ntchito mphamvu zamagetsi.

Refrigerant yokwanira iyenera kukonzedwa pasadakhale musanayipire firiji.Mukadzaza, imatha kudzazidwa mwachindunji kuchokera ku valve yapadera yodzaza.Popeza dongosolo lili mu vacuum state, kuthamanga kusiyana pakati pa refrigerant mu silinda ndi dongosolo ndi lalikulu.Valavu ikatsegulidwa (mpweya mu chitoliro cholumikizira uyenera kuwomberedwa ndi refrigerant poyamba, kuti mpweya usalowe mu unit ndikukhudza magwiridwe antchito a unit), refrigerant imatulutsidwa mwachangu kuchokera ku silinda.Pambuyo podzaza dongosolo, valve yodzaza iyenera kutsekedwa poyamba, ndiyeno chitoliro cholumikizira chiyenera kuchotsedwa.

Pamene kutentha kwa condenser kuli koipa, mphamvu ya compressor imakhala yochepa ndipo ntchito yamakono imawonjezeka.Kuthamanga kwa mpweya wozizira kwambiri kumakwera kufika pa 24kg / cm2, ndipo madzi atakhazikika-kuthamanga kwapamwamba kumakwera kufika 20kg / cm2, compressor imagwedezeka ndi chitetezo chapamwamba, ndipo kompresa imasiya Ntchito, kutentha kosauka. kutayika, kuchulukirachulukira kwamphamvu komanso chizindikiro cholakwika kapena cholakwika chikuwonetsedwa.Pakadali pano, chonde onani ngati madzi ozungulira a nsanja yozizirira ndi abwinobwino, ngati kutentha kwa madzi ozizira ndikokwera kwambiri, ngati pampu yoziziritsira nsanja ikuyenda, komanso ngati valavu yamadzi ozizira yatsegulidwa kwathunthu (chonde onani ngati nsanja yozizirirayo yatseguka kwathunthu).Kaya radiatoryo ndi yakuda kapena yotsekedwa), dinani batani lokhazikitsira pambuyo poti zili bwino, kapena tsekani ndikuyambiranso kugwira ntchito moyenera.Ngati kuchulukitsidwa kwamphamvu kumachitika pafupipafupi, chonde konzekerani kuyeretsa condenser mwachangu momwe mungathere.

Muyezo wanthawi zonse wa screw chiller uyenera kukwaniritsa mfundo izi:
1. Kutentha kwamafuta a kompresa ndi za 40-55 ℃;
2. Kutentha kwa mpweya wa kompresa ndi 45-90 ℃, ndipo kutentha kwakukulu sikudzapitirira 1.05 ℃;
3. Kuthamanga kwa mpweya wa compressor ndi 1.8 ~ 1.47MPa (kuthamanga kwa gauge);
4. Kuthamanga kwa mafuta a kompresa ndi 0.2 ~ 0.3MPa (kuthamanga kwa gauge);
5. Panthawi yogwiritsira ntchito compressor, phokoso liyenera kukhala lofanana komanso lokhazikika, ndipo pasakhale phokoso losamveka;
6. Kutentha kwa evaporation kwa unit kuyenera kukhala 3-4 ℃ kutsika kuposa kutentha kwamadzi mufiriji, ndipo kutentha kwamadzi a refrigerant kumakhala pafupifupi 5-7 ℃;
7. Kutentha kwa mpweya wa unit kuyenera kukhala 3-5 ℃ kuposa kutentha kwa madzi ozizira;Mzati ozizira ndi kutentha ayenera kulamulidwa pafupifupi 40 ℃, ndi condenser polowera madzi kutentha ayenera kukhala pansi 32 ℃.

Kunja pamwamba pa ophatikiza ozizira yosungirako:
Yambani ndi zotsukira zofatsa ndi madzi ofunda kuti pamwamba pakhale kutha, musagwiritse ntchito zotsuka zotsukira kapena zomatira pokucha.
Mkati pamwamba ophatikizana ozizira yosungirako:
Gwiritsani ntchito zotsukira m'nyumba, zotsukira amino ndi njira zowonongeka kuti muyeretse m'kati, zomwe sizingawononge pamwamba , Osawaza madzi pazigawo zamagetsi, musagwiritse ntchito zosungunulira, mafuta kapena asidi.

Gulu la screw chillers:
1. Malingana ndi ntchito ya mpweya, imagawidwa kukhala mtundu umodzi wozizira komanso mtundu wa pampu ya kutentha.
2. Malinga ndi mafiriji osiyanasiyana omwe amagwiritsidwa ntchito, amagawidwa m'mitundu iwiri: R134a ndi R22.
3. Malingana ndi njira yake yochepetsera, imagawidwa m'madzi ozizira potola ndi mpweya wozizira wozizira!
4. Malingana ndi mawonekedwe osindikizira a compressor, amagawidwa kukhala mtundu wotseguka, mtundu wotsekedwa ndi mtundu wotsekedwa kwathunthu.
5. Malinga ndi kapangidwe ka evaporator, imatha kugawidwa mumtundu wamba komanso wosefukira.
6. Malingana ndi ma compressor osiyanasiyana opangira firiji omwe amagwiritsidwa ntchito mu screw chiller, amagawidwa.Screw refrigeration compressor amagawidwa m'mitundu iwiri: mapasa-screw ndi single-screw.Mawiri-screw refrigeration compressor ali ndi ma rotor okhala ndi mano a helical akukuta molunjika mbali zina.Compressor ya firiji ya single-screw ili ndi zomangira zozungulira zokhala ndi 6 helical grooves yokonzedwa panja ya cylindrical.Palinso magiya a mapulaneti ofanana ndendende okhala ndi zoyika 11 zoyikidwa moyimirira kumanzere ndi kumanja kwa gulugufe ndi ndodo!Kumvetsetsa mwatsatanetsatane m'magulu a screw chiller mosakayikira ndikothandiza kwambiri kwa abwenzi omwe akufunika kugula zoziziritsa kukhosi!

Njira yowerengera:
1: Voliyumu (malita) × chiwerengero cha malita a kutentha ÷ nthawi yotentha (mphindi) × 60 ÷ 0.86 (coefficient) = (W)
2: Voliyumu (matani kapena ma kiyubiki metres) × chiwerengero cha malita a kutentha ÷ nthawi yotentha (maola) ÷ 0.86 (coefficient) = (KW) ngati mubweretsa deta yanu, mutha kupeza maola 4 10000L×(15-7)÷ 4h÷0.86=23255W =23.255KW maola 5 matani 10×(15-7)÷5h÷0.86=18.604KW
