Kodi mukudziwa momwe mungasungunulire chipinda chozizirachi - Defrost Heating Tube?

A. Chidule

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. 

B. 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.

C. njira zosungunula

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 kusungunula chitoliro chachikulu, chapakati komanso chaching'ono chosungiramo zinthu zozizira:

Mpweya wotentha kwambiri wotentha umalowetsedwa mwachindunji mu evaporator popanda kuletsa, ndipo kutentha kwa evaporator kumakwera, zomwe zimapangitsa kuti chisanu ndi malo ozizira olumikizirana ndi mpweya wozizira zisungunuke kapena kuchotsedwa. Kusungunula mpweya wotentha ndikotsika mtengo komanso kodalirika, ndikosavuta kukonza ndi kuyang'anira, ndipo ndalama zake ndi zovuta zake zomanga sizazikulu.

2, kupopera madzi kusungunula chisanu

Amagwiritsidwa ntchito kwambiri posungunula chiller chachikulu ndi chapakati:

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 lokhala ndi kutentha kozizira kwambiri, monga 5% mpaka 8% ya madzi oundana, kuti mupewe kuzizira.

3, kusungunula chisanu kwa magetsi

Chitoliro chotenthetsera chamagetsi chimagwiritsidwa ntchito kwambiri pa zoziziritsira zapakati ndi zazing'ono:

Waya wotenthetsera wamagetsi amagwiritsidwa ntchito makamaka posungunula chubu cha aluminiyamu mzere wotenthetsera wamagetsi m'malo ozizira apakatikati ndi ang'onoang'ono, zomwe ndi zosavuta kugwiritsa ntchito pozizira; Komabe, pankhani yosungiramo zinthu zozizira za chubu cha aluminiyamu, zovuta pakupanga zipini za aluminiyamu za waya wotenthetsera wamagetsi sizochepa, ndipo kulephera kwake kumakhala kwakukulu mtsogolo, kukonza ndi kuyang'anira kumakhala kovuta, chuma sichikuyenda bwino, ndipo chitetezo chili chochepa.

4, kusungunula kwa makina opangira

Chitoliro chosungiramo zinthu zozizira chaching'ono chimagwiritsidwa ntchito posungunula chisanu:

Kusungunula chitoliro chosungiramo zinthu zozizira ndi njira yotsika mtengo, njira yoyambirira yosungunula zinthu zozizira. Kusunga zinthu zozizira zambiri pogwiritsa ntchito kusungunula zinthu zopangidwa sikoyenera, kugwira ntchito kwa mutu kumakhala kovuta, kugwiritsa ntchito zinthu zakuthupi kumathamanga kwambiri, nthawi yosungiramo zinthu m'nyumba yosungiramo zinthu ndi yayitali kwambiri komanso yovulaza thanzi, kusungunula zinthu sikophweka kuchita bwino, kungayambitse kusintha kwa evaporator, ndipo kungawononge evaporator zomwe zimapangitsa ngozi zotayikira.

D. njira yosankhira njira yosungunula fluorine system

Malinga ndi makina osiyanasiyana oyeretsera zinthu zozizira, sankhani njira yoyenera yoyeretsera zinthu zozizira. Malo ochepa osungira zinthu zozizira amagwiritsa ntchito chitseko chotseka kuti asungunuke mwachilengedwe pogwiritsa ntchito kutentha kwa mpweya. Mafiriji ena otentha kwambiri amasankha kuyimitsa firiji, kutsegula fani yotenthetsera padera, kugwiritsa ntchito fani kufalitsa mpweya kuti usungunuke, ndipo salola kuti chitoliro chotenthetsera chamagetsi chikwaniritse cholinga chosunga mphamvu.

1, njira yosungunula madzi pogwiritsa ntchito choziziritsira:

(1) Pali machubu amagetsi osungunula ndipo madzi osungunula akhoza kusankhidwa, madera omwe ali ndi madzi abwino kwambiri angasankhe choziziritsira madzi osungunula, madera omwe madzi akusowa angakonde kusankha choziziritsira madzi osungunula, madera omwe madzi akusowa angakonde kusankha choziziritsira madzi osungunula.

(2) kusungunula chubu chamagetsi kumagwiritsidwa ntchito kwambiri posungunula choziziritsa mpweya chaching'ono; Choziziritsa chisanu chothira madzi nthawi zambiri chimayikidwa mu 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 zina zosungunula fluoride ndi thermal thermal defrosting.

E. nthawi yosungunula yosungiramo zinthu zozizira

Tsopano kusungunuka kwa madzi ambiri m'malo ozizira kumayendetsedwa malinga ndi kutentha kwa madzi kapena nthawi yosungunuka. Kuchuluka kwa madzi, nthawi, ndi kutentha kwa madzi kuyenera kusinthidwa malinga ndi kuchuluka ndi mtundu wa katundu wosungidwa.

Pamapeto pa nthawi yosungunula, kenako mpaka nthawi yothira madzi, fani imayamba. Samalani kuti musataye nthawi yosungunula madzi nthawi yayitali ndipo yesetsani kusungunula madzi moyenera. (Nthawi zambiri nthawi yosungunula madzi imadalira nthawi yamagetsi kapena nthawi yoyambira compressor.)

F. Kusanthula zomwe zimayambitsa chisanu chochuluka

Pali zifukwa zambiri zomwe zimakhudza kupangika kwa chisanu, monga: kapangidwe ka evaporator, malo okhala mumlengalenga (kutentha, chinyezi) ndi kuchuluka kwa mpweya. Zotsatira zake pa kupangika kwa chisanu ndi magwiridwe antchito a mpweya wozizira ndi izi:

1, kusiyana kwa kutentha pakati pa mpweya wolowera ndi fan yosungiramo zinthu zozizira;

2, chinyezi cha mpweya wopumira;

3, mtunda pakati pa zipsepse;

4, kuchuluka kwa mpweya wolowera.

Pamene kutentha kosungirako kuli kokwera kuposa 8℃, njira yosungiramo yozizira nthawi zonse siizizira kwambiri; Pamene kutentha kozungulira kuli -5℃ ~ 3℃ ndipo chinyezi cha mpweya chili chachikulu, choziziritsira mpweya chimakhala chosavuta kuzizira; Pamene kutentha kozungulira kwatsika, liwiro la kupanga chisanu limachepa chifukwa chinyezi chomwe chili mumlengalenga chimachepa.
