Chifukwa cha chisanu chomwe chili pamwamba pa evaporator mu malo osungiramo zinthu ozizira, chimalepheretsa kuyendetsa ndi kufalitsa mphamvu yozizira ya evaporator yoziziritsa (payipi), ndipo pamapeto pake chimakhudza momwe firiji imagwirira ntchito. Pamene makulidwe a chisanu (ayezi) pamwamba pa evaporator afika pamlingo winawake, mphamvu yoziziritsa imatsika mpaka pansi pa 30%, zomwe zimapangitsa kuti mphamvu zamagetsi ziwonongeke kwambiri ndikufupikitsa nthawi yogwira ntchito ya makina oziziritsa. Chifukwa chake, ndikofunikira kuchita ntchito yosungunula chisanu chosungiramo zinthu ozizira munthawi yoyenera.
Cholinga cha kusungunula
1, kukonza bwino ntchito yoziziritsa m'firiji;
2. Onetsetsani kuti zinthu zozizira zili bwino m'nyumba yosungiramo katundu
3, kusunga mphamvu;
4, kukulitsa moyo wautumiki wa makina osungira ozizira.
Njira yosungunula
Njira zosungunula chisanu m'malo ozizira: kusungunula mpweya wotentha (kusungunula fluorine wotentha, kusungunula ammonia wotentha), kusungunula chisanu m'madzi, kusungunula chisanu m'magetsi, kusungunula chisanu m'makina (opangidwa ndi makina), ndi zina zotero.
1, kusungunula mpweya wotentha
Yoyenera chitoliro chachikulu, chapakati komanso chaching'ono chosungiramo zinthu zozizira chomwe chimasungunula mwachindunji mpweya wotentha kwambiri wozizira kulowa mu evaporator popanda kuletsa kuyenda, kutentha kwa evaporator kumakwera, ndipo chisanu ndi cholumikizira chotulutsa chozizira zimasungunuka kapena kuchotsedwa. Kusungunula mpweya wotentha ndi kotsika mtengo komanso kodalirika, ndikosavuta kukonza ndi kuyang'anira, ndipo ndalama zake ndi zovuta zake zomanga sizazikulu. Komabe, palinso njira zambiri zosungunula mpweya wotentha, zomwe zimachitika nthawi zambiri ndikutumiza mpweya wothamanga kwambiri komanso wotentha kwambiri womwe umatuluka mu compressor kupita ku evaporator kuti utulutse kutentha ndi kusungunula, kotero kuti madzi oundanawo amalowa mu evaporator ina kuti atenge kutentha ndi kusungunuka kukhala mpweya wotentha kwambiri komanso wothamanga pang'ono, kenako nkubwerera ku compressor suction port kuti amalize kuzungulira.
2, kupopera madzi kusungunula chisanu
Amagwiritsidwa ntchito kwambiri posungunula ma chiller akuluakulu ndi apakatikati
Thirani madzi otentha mu evaporator nthawi ndi nthawi kuti musungunule chisanu. Ngakhale kuti kusungunuka kwake kuli bwino kwambiri, ndikoyenera kwambiri pa zoziziritsira mpweya, ndipo n'kovuta kugwiritsa ntchito pa ma evaporation coils. N'zothekanso kupopera evaporator ndi yankho lozizira kwambiri, monga 5%-8% ya madzi oundana, kuti mupewe chisanu.
3. Kusungunula chisanu kwa magetsi
Kusungunula chitoliro chamagetsi chotenthetsera chimagwiritsidwa ntchito kwambiri mu choziziritsira mpweya chapakati ndi chaching'ono; Kusungunula waya wotenthetsera wamagetsi kumagwiritsidwa ntchito kwambiri mu machubu a aluminiyamu apakati ndi ang'onoang'ono osungiramo zinthu zozizira.
Kusungunula kutentha kwamagetsi, kwa chiller ndikosavuta kugwiritsa ntchito; Komabe, pankhani yosungiramo zinthu zozizira pogwiritsa ntchito chubu cha aluminiyamu, zovuta pakupanga zipini za aluminiyamu za waya wotenthetsera wamagetsi sizochepa, ndipo kulephera kwa magetsi kudzakwera kwambiri mtsogolo, kukonza ndi kuyang'anira n'kovuta, ndalama sizikuyenda bwino, ndipo chitetezo chili chotsika.
4, kusungunula kwa makina opangira
Kusungunula chitoliro chaching'ono chosungiramo zinthu zozizira pogwiritsa ntchito chitoliro chosungiramo zinthu zozizira Kusungunula chitoliro chamanja ndi njira yotsika mtengo, njira yoyambirira kwambiri yosungunula chitoliro. Kusunga chitoliro chachikulu chozizira pogwiritsa ntchito kusungunula zinthu zopangidwa ndi anthu sikungatheke, kugwira ntchito molimbika ndi kovuta, kugwiritsa ntchito mphamvu mwachangu kwambiri, nthawi yosungiramo zinthu m'nyumba yosungiramo zinthu ndi yayitali kwambiri, kuwononga thanzi, kusungunula sikophweka kumaliza, kungayambitse kusintha kwa evaporator, ndipo kungaswe evaporator ndikuyambitsa ngozi zotayikira mufiriji.
Kusankha njira (dongosolo la fluorine)
Malinga ndi makina osiyanasiyana oyeretsera zinthu ozizira, njira yoyenera yosungunula zinthu imasankhidwa, ndipo mphamvu zomwe zimagwiritsidwa ntchito, kugwiritsa ntchito zinthu zotetezera, kuyika ndi kuvutika kwa ntchito zimafufuzidwanso.
1, njira yosungunula chisanu ya fan yozizira
Pali machubu amagetsi osungunula ndipo osungunula madzi amatha kusankha. Madera omwe ali ndi madzi osavuta kugwiritsa ntchito angakonde choziziritsira chisanu chotsukira madzi, ndipo madera omwe alibe madzi ambiri amakonda kusankha choziziritsira chisanu chotsukira madzi chotsukira madzi. Choziziritsira chisanu chotsukira madzi nthawi zambiri chimakhala ndi makina akuluakulu oziziritsira mpweya komanso oziziritsira.
2. Njira yosungunula chitsulo
Pali njira zina zosungunula fluorine yotentha komanso njira zopangira fluorine.
3. Njira yosungunula chitsulo cha aluminiyamu
Pali njira zosungunula fluoride ndi kutentha kwa magetsi. Pogwiritsa ntchito kwambiri evaporator ya aluminiyamu, kusungunula kwa chubu cha aluminiyamu kwakhala kukuyang'aniridwa kwambiri ndi ogwiritsa ntchito. Chifukwa cha zinthu zakuthupi, chubu cha aluminiyamu sichoyenera kugwiritsa ntchito njira yosavuta komanso yolimba yosungunula makina ngati chitsulo, kotero njira yosungunula ya chubu cha aluminiyamu iyenera kusankha njira yosungunula waya wamagetsi ndi njira yosungunula fluorine yotentha, kuphatikiza kugwiritsa ntchito mphamvu, chiŵerengero cha mphamvu yogwiritsira ntchito bwino komanso chitetezo ndi zina, kusungunula chubu cha aluminiyamu ndikoyenera kwambiri kusankha njira yosungunula fluorine yotentha.
Kugwiritsa ntchito fluoride yotentha
Zipangizo zosinthira kayendedwe ka freon zomwe zimapangidwa motsatira mfundo yosungunula mpweya wotentha, kapena njira yosinthira yopangidwa ndi ma valve angapo amagetsi (ma valve amanja) olumikizidwa, kutanthauza, malo owongolera firiji, zimatha kugwiritsa ntchito kusungunula kwa fluorine wotentha m'malo ozizira.
1, siteshoni yosinthira pamanja
Amagwiritsidwa ntchito kwambiri m'makina akuluakulu oziziritsira monga kulumikizana kofanana.
2, zida zosinthira kutentha kwa fluorine
Imagwiritsidwa ntchito kwambiri mu makina ang'onoang'ono komanso apakatikati osungiramo zinthu zoziziritsira. Monga: chipangizo chimodzi chofunikira kwambiri chosinthira fluorine yotentha.
Kutulutsa fluorine yotentha kamodzi kokha
Ndi yoyenera kugwiritsa ntchito makina odziyimira pawokha a compressor imodzi (siyiyenera kuyikidwa pa kulumikizana kwa mayunitsi ofanana, ambiri komanso olumikizana). Imagwiritsidwa ntchito posungunula mapaipi ang'onoang'ono komanso apakatikati osungiramo zinthu zozizira komanso kusungunula ayezi.
zachilendo
1, kulamulira pamanja, kusintha kamodzi kokha.
2, kutentha kuchokera mkati, chisanu ndi khoma la chitoliro zimatha kusungunuka ndi kugwa, chiŵerengero cha mphamvu zogwiritsira ntchito bwino ndi 1:2.5.
3, kusungunuka bwino, kupitirira 80% ya chisanu ndi dontho lolimba.
4, malinga ndi zojambula zomwe zayikidwa mwachindunji pa chipangizo choziziritsira mpweya, sizifunikira zida zina zapadera.
5, malinga ndi kusiyana kwenikweni kwa kutentha kwa malo ozungulira, nthawi zambiri zimatenga mphindi 30 mpaka 150.
