Condenser ndi imodzi mwazida zosinthira kutentha mufiriji.Ntchito yake ndikutulutsa mpweya wotentha kwambiri wa refrigerant kuchokera ku kompresa, momwe kutentha kumatulutsira kumalo osungira zachilengedwe ndikukhazikika, kusungunula mumadzi odzaza, kapena ngakhale madzi ozizira kwambiri.
Malingana ndi njira yozizirira yosiyana siyana ndi njira yozizirira yomwe imagwiritsidwa ntchito ndi condenser, pali mitundu itatu ya madzi ozizira, ozizira mpweya ndi madzi ozizira.
Njira yozizira ya Condenser:
Woziziritsidwa ndi mpweya, woziziritsidwa ndi madzi, woziziritsidwa ndi mpweya (madzi ndi mpweya utakhazikika)
Malinga ndi mawonekedwe a mpweya kunja kwa chitoliro mu mpweya utakhazikika condenser:
Natural convection mpweya utakhazikika condenser, kukakamiza convection mpweya utakhazikika condenser
Choyamba, madzi utakhazikika condenser
Mtundu woterewu wa condenser umagwiritsa ntchito madzi ngati njira yozizirirapo kuti achotse kutentha komwe kumatulutsa firiji ikakhazikika.Madzi ozizira amatha kugwiritsidwa ntchito kamodzi kapena kubwezeretsedwanso.
Madzi ozungulira akagwiritsidwa ntchito, nsanja zozizirira kapena maiwe ozizira ziyenera kukhala ndi zida kuti madziwo azizizira nthawi zonse.Malinga ndi kapangidwe kake kosiyana, pali makamaka chipolopolo ndi mtundu wa chubu ndi mtundu wa chubu ndi chosinthira kutentha kwa mbale zomwe zimagwiritsidwa ntchito tsopano.
Chigoba chopingasa ndi chubu condenser
1. Chipolopolo ndi chubu condenser:
Mafiriji osiyanasiyana amagwiritsidwa ntchito mufiriji, ndipo mawonekedwe awo amasiyananso.Nthawi zambiri, chigoba choyimirira ndi ma chubu condensers ndi oyenera mayunitsi akulu ammonia firiji, pomwe chipolopolo chopingasa ndi machubu condensers amagwiritsidwa ntchito mu mayunitsi akulu ndi apakatikati ammonia kapena freon firiji.Chipinda cha chubu ndi chubu chotengera kutentha nthawi zambiri chimakhazikika ndi njira yowonjezera, kuti athe kukonza ndikusintha chubu chotengera kutentha.
2. Maonekedwe a chipolopolo chopingasa ndi chubu condenser:
Kutentha kwakukulu kwa kutentha kwapakati, kuchepa kwa madzi ozizira, ntchito yosavuta ndi kasamalidwe;Koma ubwino wa madzi a madzi ozizira ndi apamwamba.Chipangizo chamtunduwu chimagwiritsidwa ntchito kwambiri m'magawo akulu ndi apakatikati afiriji pakadali pano.
Chigoba chowongoka ndi chubu condenser
1 - chitoliro chamadzimadzi;2 - cholumikizira choyezera kuthamanga;3 - chitoliro chodyera;4 - thanki yogawa madzi;5 - olowa valavu chitetezo;6 - chitoliro chofanana ndi kuthamanga;7 - chitoliro chopanda kanthu;8 - Kuwombera
3. Casing condenser:
Ndi condenser yoziziritsidwa ndi madzi yopangidwa ndi machubu a mainchesi osiyanasiyana omwe amameta ndi kupindika kukhala mawonekedwe ozungulira kapena mawonekedwe a njoka.Monga momwe tawonetsera pachithunzichi, mpweya wa refrigerant umafupikitsidwa pakati pa manja, ndipo condensate imachotsedwa pansi.Madzi ozizira amayenda pansi-mmwamba mu chitoliro chaching'ono cham'mimba mwake, kupanga mtundu wotsutsana ndi refrigerant, kotero kuti kutentha kwa kutentha kumakhala bwino.
Tube condenser
4. Cholumikizira mbale:
Plate condenser imapangidwa ndi zitsulo zosapanga dzimbiri zosapanga dzimbiri, zomwe zimapanga njira yamadzi ozizira komanso otentha mbali zonse za mbale yotengera kutentha, ndipo imatulutsa kutentha kudzera pakhoma la mbale poyenda.
Makulidwe a mbale yotengera kutentha ndi pafupifupi 0.5mm, ndipo katayanidwe ka mbale nthawi zambiri ndi 2-5mm.
Plate heat exchanger ndi yaying'ono mu voliyumu, yopepuka kulemera, yotentha kwambiri yotengera kutentha, yocheperako firiji yofunikira, yodalirika kwambiri ndipo yakhala ikugwiritsidwa ntchito kwambiri m'zaka zaposachedwa.Koma voliyumu yake yamkati ndi yaying'ono, refrigerant yamadzimadzi yosungunuka iyenera kuthetsedwa munthawi yake, zofunikira zamadzi ozizira ndizokwera, zovuta kuyeretsa, kutulutsa kwamkati sikophweka kukonza.
Madzi ozizira amapita mmwamba ndi pansi, nthunzi ya refrigerant imalowa kuchokera pamwamba, ndipo furiji yamadzimadzi imatuluka kuchokera pansi.
Chachiwiri, cholumikizira mpweya
Condenser imagwiritsa ntchito mpweya ngati sing'anga yozizira.Refrigerant imafupikitsidwa mu chitoliro, ndipo mpweya umayenda kunja kwa chitoliro kuti utenge kutentha komwe kumatulutsidwa ndi nthunzi ya refrigerant mupaipi.Chifukwa cha mpweya wochepa wotengera kutentha, zipsepse nthawi zambiri zimayikidwa kunja kwa chubu (mbali ya mpweya) kuti ziwonjezere kutentha kunja kwa chubu.Pali mitundu iwiri ya mpweya wopanda mpweya komanso mpweya wokakamizidwa.
1. Condenser yozizirira mpweya yokhala ndi mpweya womasuka:
Condenser imagwiritsa ntchito mpweya wotuluka kunja kwa chubu kuti utenge kutentha komwe kumachokera mufiriji.Kusintha kwa kachulukidwe kumapangitsa kuti mpweya uziyenda mwaulere ndipo nthawi zonse umachotsa kutentha kwa condensation kwa nthunzi ya refrigerant.Sichifuna fani, palibe phokoso, chogwiritsidwa ntchito kwambiri m'magawo ang'onoang'ono a firiji.Monga momwe chithunzi chili pansipa:
Mpweya woziziritsidwa wa condenser wokhala ndi mpweya wokakamiza: Monga momwe tawonera pachithunzi pansipa, uli ndi machubu amodzi kapena angapo okhala ndi njoka okhala ndi zipsepse.Mpweya wa refrigerant umalowa mu chubu cha njoka kuchokera ku chotolera chapamwamba, ndipo chipsepse chakunja cha chubucho chimagwiritsidwa ntchito kulimbikitsa kutengera kutentha kwa mbali ya mpweya ndikubwezeranso kutsika kwa kutentha kwa mpweya.
Pankhani ya kapangidwe kake, mizere yambiri ya chubu motsatira njira yomwe mpweya umayendera, kumachepetsa kutentha kwa mzere wakumbuyo, kuti mphamvu yotengera kutentha isagwiritsidwe ntchito mokwanira.Kuti muwongolere kuchuluka kwa malo osinthira kutentha, ndi bwino kusankha mizere 4-6 ya mapaipi.
2. Kuyerekeza pakati pa mpweya woziziritsidwa condenser ndi madzi utakhazikika condenser:
(1) M’malo amene madzi ozizirirapo ndi okwanira, ndalama zoyamba zogulira ndi kugwiritsira ntchito zipangizo zoziziritsira madzi ndizochepa kuposa za zipangizo zoziziritsira mpweya;
(2) Chifukwa cha kutentha kwakunja kwa mpweya m'chilimwe, kutentha kwa condensation kumatha kufika 50.℃.Kuti mupeze mphamvu yoziziritsa yomweyi, mphamvu ya firiji ya compressor ya zida zoziziritsa mpweya iyenera kuwonjezeka ndi pafupifupi 15%;
(3) Makina opangira firiji pogwiritsa ntchito mpweya woziziritsa mpweya ndi wosavuta, womwe ungathe kuthetsa kusowa kwa madzi;
Chachitatu, evaporative condenser
1. Condenser ya evaporative:
Ndi madzi ndi mpweya ngati sing'anga yozizira.Imagwiritsa ntchito mpweya wamadzi kuti utenge kutentha kuti upangitse mpweya wa refrigerant mu chitoliro.Madzi amanyamulidwa ndi mpope ndiyeno amawapopera pamwamba pa chubu chotengera kutentha ndi nozzle kuti apange filimu yamadzi.Mbali ina ya madzi yomwe imatenga kutentha imasanduka nthunzi mu nthunzi yamadzi, kenako imachotsedwa ndi mpweya wolowa mu condenser.
Madontho amadzi omwe sachita nthunzi amagwera m'dziwe pansi.Kusakaniza kwamadzi kumakonzedwa pamwamba pa bokosi la bokosi.Amagwiritsidwa ntchito kuti madontho amadzi asatuluke mumlengalenga.Mfundo ya kapangidwe ka evaporative condenser ikuwonetsedwa pachithunzichi.
2. Makhalidwe a evaporative condenser:
(1) Kugwiritsa ntchito vaporization ya madzi kuchotsa kutentha kwa condensation, madzi ozizira omwe amagwiritsidwa ntchito ndi madzi otayika okha, madzi ozizira ndi ochepa;
(2) Kutentha kwa babu yolowera mumlengalenga kumakhudza kwambiri kusinthana kwa kutentha.Pakutentha komweku komweko komanso kuchuluka kwa mpweya, kutentha kwa babu kukakhala kochepa kwambiri, madzi ozizira amakhala ndi nthunzi wochuluka, ndipo m'pamenenso mpweya wozizira umakhala wabwino.
(3) Mpweya wotsekemera umakhala ndi madzi ochepa, ndipo mpweya wofunikira ndi wosakwana 1/2 wa mtundu wozizira wa mpweya, choncho ndi woyenera makamaka kumadera ouma omwe alibe madzi.
