Nyama yowonjezera mafuta, chubu capillary, valavu yamagetsi, zinthu zitatu zofunika kwambiri
Njira yopanda kanthu ndi imodzi mwazinthu zofunikira mu chipangizo chokwanira. Ntchito yake ndikuchepetsa madzi okwanira (kapena ogonjera madzi) pansi pa kukakamizidwa kwa Condenser kapena kulandiridwa kwamadzimadzi ku kukakamizidwa kwa Epeaporation ndi kutentha kwaulere pambuyo pake. Malinga ndi kusintha kwa katundu, kuyenda kwa firiji kulowa mu Evaporatora kumasinthidwa. Zida zodziwika bwino kwambiri zimaphatikizapo machubu a capillary, ma valves okumbika, ndi mavavu oyandama.
Ngati kuchuluka kwa madzi omwe amaperekedwa ndi makina otumphuka ku EvaPorator ndi okulirapo poyerekeza ndi katundu wa Evapor, gawo la firiji lokhala ndi firiji kapena kuwononga ngozi kapena ngozi zamadzimadzi.
M'malo mwake, ngati kuchuluka kwa madzi ndi ochepa kwambiri poyerekeza ndi kuchuluka kwa magazi, gawo la malo osinthira kutentha kwa EvaPorator sangathe kugwira ntchito, ndipo ngakhale kukakamizidwa kwa magaziwo kuchepetsedwa; Ndipo mphamvu yozizira ya dongosololi idzachepetsedwa, zokongoletsa zozizira zidzachepetsedwa, ndipo compressor kutentha kutentha kumakwera, komwe kumakhudzanso mafuta wamba a compressor.
Madzi a firiji atadutsa bowo laling'ono, gawo lazovuta zokhazikika zimasinthidwa kukhala zovuta, ndipo kuchuluka kwake kumawonjezeka, ndipo kuthamanga kochepa kumachepa, kotero kuti madziwo amatha kukwaniritsa cholinga chochepetsa mphamvu ndikukonzanso.
Kusoka ndi imodzi mwa njira zazikuluzikulu zinayi zomwe zikugwirizana ndi nyengo yopanga yopanga.
Njira Yosoka ili ndi ntchito ziwiri:
Chimodzi chonyansa komanso chonyansa chambiri chodzaza ndi madzi okwera kwambiri kuchokera kwa wogonjetsedwa ndi kupanikizika
Lachiwiri ndikusintha kuchuluka kwa firiji yamadzi kulowa mu EvaPorator malinga ndi dongosolo la dongosolo.
1. Makina owonjezera owonjezera
Nyama yowonjezera imagwiritsidwa ntchito kwambiri ku Fren firiji. Kudzera mu ntchito yamagetsi yowonjezera, imasintha kusintha kwa kutentha kwa firiji pokonzanso kuti akwaniritse cholinga chosintha madzi.
Ma valves ambiri owonjezera mafuta amatha kukhala ndi mainchesi apamwamba kwambiri pa 5 mpaka 6 ° C asanachoke fakitale. Kapangidwe ka Valavu kumatsimikizira kuti wapamwamba kwambiri ukachulukana ndi wina 2 ° C, valavu imatseguka kwathunthu. Pamene wapamwamba ndi pafupifupi 2 ° C, valavu yowonjezera itsekedwa. Kusintha kasupe wowongolera wapamwamba, kusinthasintha kwa 3 ~ 6 ℃.
Nthawi zambiri, oyandikira kwambiri opangidwa ndi matenthedwe owonjezera, chifukwa chotsitsa kutentha kwamphamvu kwambiri. Imakhala gawo la malo osinthira a Evaporator ku Evaporator kuphika, kotero kuti malo amphiri a firiji ndi kutentha kumakhala kochepetsedwa, ndiye kuti, pamwamba pa Epapprator sikugwiritsidwa ntchito mokwanira.
Komabe, ngati digiri yapamwamba kwambiri ndi yotsika kwambiri, madzi firiji atha kubweretsedwa mu compressor, zomwe zimapangitsa chisangalalo chamadzimadzi chamadzimadzi. Chifukwa chake, malamulo a superheat ayenera kukhala oyenera kuwonetsetsa kuti firiji yokwanira imalowa mu Evaptoray poletsa madzi firiji polowa compression.
Valavu yowonjezera imapangidwa makamaka ndi thupi la valavu, phukusi la kutentha kwa kutentha ndi chubu capillary. Pali mitundu iwiri ya matenthedwe owonjezera: mtundu wamkati wamkati ndi mtundu wakunja malinga ndi njira zokwanira diaphragm.
Makina owerengera mkati mwawo
Valani wa materi mkati mwathunthu umapangidwa ndi thupi la valavu, kanikizani ndodo, chikho cha Valave, masika, kutentha kwa bomba, pezani matenda a diaphragm ndi zina zophatikizira.
Mafuta oyenda bwino
Kusiyana pakati pa gawo lakunja kwa mtundu wa matenthedwe ndi mtundu wa mawonekedwe amkati ndi malo omwe ali ndi vuto lokhala ndi valavu ya diaphragm, koma chitoliro chochepa kwambiri chimagwiritsidwa ntchito polumikizana ndi malo ogulitsira. Mwanjira imeneyi, kukakamizidwa kufinya kumagwira ntchito pa diaphragm sikuli koloko povota pambuyo pake, koma kupsinjika PC yopukutira kwa Evaporator. Pamene mphamvu ya diaphragm imakhala yolondola, ndi PG = PC + PW. Ditiri wotseguka wa valavu siyikhudzidwa ndi kutsutsana kochokera mu coil, motero kuthana ndi zolakwa za mtundu wamkati. Mtundu woyenera wakunja umagwiritsidwa ntchito kwambiri pakapita nthawi yomwe singano ya Evaporat ndi yayikulu.
Nthawi zambiri, ma Stear Superheat digiri ya kukula kwatsekedwa amatchedwa digiri ya Otsekedwa Kutsekera kwambiri kumakhudzana ndi kuphulika kwa kasupe, komwe kumatha kusinthidwa ndi kusintha kwa lever.
Sukulu yapamwamba pomwe kasupe amasinthidwa kukhala malo otumphuka amatchedwa ofiyira otsekeka kwambiri; M'malo mwake, sunheat pamene kasupe umasinthidwa kukhala wowopsa womwe umatchedwa pamwamba kwambiri. Nthawi zambiri, digiri yotsika yaposachedwa ya valve sing kuposa 2 ℃, ndipo digiri yapamwamba kwambiri yotseka siyochepera 8 ℃.
Kuti muchepetse bwino kwambiri mafuta ochulukirapo, valavu yozungulira, yokakamizika imagwira ntchito mu diaphragm. Ngati kukana kwa EvaPorator ndi yayikulu, kudzakhala kutaya kwakukulu kwakukulu pomwe firiji imayenda m'malo ena okhazikika, omwe angakhudze kwambiri mafuta ochulukirapo. Kugwirira ntchito kwa Evapotor kumawonjezera, zomwe zimapangitsa kuti ziwonjezeke pa superheat pamlingo wowonjezera, ndipo kugwiritsa ntchito njira zosafunikira kwa malo osinthira kutentha kwa EvaPotor.
Kuti muchepetse mavalidwe owonjezera owonjezera kutentha, kukakamizidwa kumachitika pansi pa diaphragm ndiye kukakamizidwa kwa extarator, osati kukakamizidwanso, ndipo zinthu zili bwino.
2. Cangillary
Capillary ndiye chipangizo chosavuta kwambiri. Capillary ndi chubu chowonda kwambiri chamkuwa chokhala ndi kutalika kwake, ndipo mulifupi mwake mkati mwa 0,5 mpaka 2 mm.
Mawonekedwe a capillary ngati chida cholocha
.
(2) Palibe zigawo zoyenda, ndipo sizophweka kuyambitsa kulephera ndi kutulutsa;
(3) ili ndi machitidwe a kudzipereka,
. Zikayambanso kuyendanso, mota compressor imayamba.
3. Valve electronic
Valavu yamagetsi ndi mtundu wothamanga, womwe umagwiritsidwa ntchito mu mphamvu yoyendetsedwa mwaluso kwambiri. Ubwino wa valavu yamagetsi yowonjezera ndi: Kusintha kwakukulu kosintha; Kuwongolera molondola; Oyenera kuwongolera anzeru; Oyenera kusintha mwachangu kwambiri.
Ubwino wa Ma Valvesion Exvesion
Mitundu yayikulu yosintha;
Kuwongolera molondola;
Oyenera kuwongolera anzeru;
Itha kugwiritsidwa ntchito posintha mwachangu mufiriji ndi mphamvu yayikulu.
Kutseguka kwa valavu ya eyapagetsi kumathamangitsidwa pakuthamanga kwa compressor, kuti kuchuluka kwa compress kumachitika kuchuluka kwa valavu yomwe imaperekedwa ndi mphamvu zowongolera mpweya zitha kutheka.
Kugwiritsa ntchito mavalidwe apakompyuta kumatha kusintha mphamvu ya compresser compressor, kuzindikira kusintha kwa kutentha kwamphamvu, ndikusintha mphamvu yamphamvu ya nyengo. Kwa zowongolera zapamwamba za mpweya wambiri, mavalo amagetsi ayenera kugwiritsidwa ntchito ngati zinthu zopanda pake.
Kapangidwe ka muyeso wamagetsi kumalima magawo atatu: kudziwika, kuwongolera ndi kuphedwa. Malinga ndi njira yoyendetsa, imatha kugawidwa mu mtundu wamagetsi ndi mtundu wamagetsi. Mtundu wamagetsi umagawidwanso mtundu wochita masewera olimbitsa thupi ndi mtundu wonyenga. Galimoto yodutsa yokhala ndi singano ya valavu ndi mtundu wogwira ntchito mwachindunji, ndipo mota yodutsamo ndi singano yokhala ndi ma valeve a varcer ndi mtundu wachinyengo.
