Condenser ndeimwe yemhando huru yekutsinhana kupisa mufiriji unit.Basa rayo ndere kuburitsa high pressure superheated refrigerant vapor kubva kucompressor, kuburikidza nekupisa kunoburitswa kune zvakatipoteredza svikiro uye kutonhodzwa, kunyungudutswa kuita saturated liquid, kana kunyange supercooled liquid.
Zvinoenderana neyakasiyana yekutonhodza yepakati uye yekutonhodza nzira inoshandiswa necondenser, kune marudzi matatu emvura-yakatonhodzwa, mhepo-inotonhorera uye mvura-mhepo yakatonhodzwa.
Condenser kutonhora mode:
Mhepo-yakatonhorera, mvura-yakatonhorera, evaporation-yakatonhorera (mvura-mhepo yakatonhodzwa)
Zvinoenderana nemhepo yekuyerera modhi kunze kwepombi mumhepo yakatonhorera condenser:
Natural convection mhepo yakatonhodzwa condenser, inomanikidzwa convection mhepo yakatonhodzwa condenser
Kutanga, mvura yakanyoroveswa condenser
Rudzi urwu rwecondenser rinoshandisa mvura senzira yekutonhodza kubvisa kupisa kunoburitswa kana firiji yanyungudika.Mvura inotonhorera inogona kushandiswa kamwe chete kana kushandiswa zvakare.
Kana mvura inotenderedzwa ichishandiswa, shongwe dzekutonhodza kana dziva dzinotonhora dzinofanirwa kunge dzakashongedzerwa kuti dzive nechokwadi chekuti mvura inogara yakatonhodzwa.Zvinoenderana nechimiro chayo chakasiyana, pane kunyanya goko uye chubhu mhando uye chubhu mhando uye ndiro yekupisa exchanger ikozvino inoshandiswa.
Horizontal shell uye chubhu condenser
1. Shell uye chubhu condenser:
Mafiriji akasiyana-siyana anoshandiswa mumidziyo yefiriji, uye maitiro avo ekugadzirisa zvakare akasiyana.Kazhinji, vertical shell uye chubhu condensers akakodzera mahombe ammonia mafiriji mayuniti, nepo horizontal shell uye chubhu condensers anowanzo shandiswa muhombe uye yepakati ammonia kana freon mafiriji mayunitsi.Iyo chubhu ndiro uye kupisa kwekutamisa chubhu zvinowanzogadziriswa nenzira yekuwedzera, kuitira kufambisa kugadzirisa nekutsiviwa kwechubhu yekupisa kupisa.
2. Hunhu hwehorizontal shell uye chubhu condenser:
Yakakwira kupisa kupisa coefficient, kushoma kutonhora kwemvura kushandiswa, nyore kushanda uye manejimendi;Asi mhando yemvura yezvinodiwa zvemvura inotonhorera yakakwirira.Rudzi urwu rwemudziyo runoshandiswa zvakanyanya mumafiriji makuru uye epakati mafiriji parizvino.
Vertical shell uye chubhu condenser
1 - mvura inobuda pombi;2 - chinongedzo chekumanikidza;3 - pombi yekupinda;4 - tangi yekugovera mvura;5 - kuchengetedza vharafu;6 - kudzvinyirira kuenzana pombi;7 - pombi isina chinhu;8 - Tubing
3. Casing condenser:
Icondenser yakatonhodzwa nemvura inogadzirwa nemachubhu emadhayamita akasiyana anoveurwa pamwe chete uye akakotama kuita spiral shape kana chimiro chenyoka.Sezvinoratidzwa mumufananidzo, iyo firiji mhute inoputirwa pakati pemaoko, uye iyo condensate inotorwa kubva pasi.Mvura inotonhora inoyerera ichidzika pasi-kumusoro mupombi duku-diameter, ichiita rudzi rwakasiyana-siyana nefiriji, saka kupisa kwekushisa kuri nani.
Tube condenser
4. Plate condenser:
Plate condenser inogadzirwa neakatevedzana esimbi isina tsvina mahwendefa, ayo anoumba inotonhora uye inopisa mvura chiteshi pamativi ese ekutamisa kupisa ndiro, uye inoita kupisa kupisa kuburikidza nemadziro eplate mukuyerera.
Ukobvu hwendiro yekutamisa kupisa hunosvika 0.5mm, uye nzvimbo yeplateti inowanzoita 2-5mm.
Plate heat exchanger idiki muhuwandu, huremu huremu, yakakwirira mukupisa kwekushisa, shoma refrigerant inodiwa, yakakwirira mukuvimbika uye yakashandiswa zvakanyanya mumakore achangopfuura.Asi vhoriyamu yaro yemukati idiki, iyo yakanyungudutswa yemvura yefiriji inofanirwa kubviswa nenguva, iyo inotonhorera yemhando yemvura inodiwa yakakwira, yakaoma kuchenesa, kubuda kwemukati hakusi nyore kugadzirisa.
Mvura inotonhorera inokwira uye ichidzika, iyo mhute yefiriji inopinda kubva kumusoro, uye refrigerant yemvura inoyerera ichibva pasi.
Chechipiri, air cooling condenser
Iyo condenser inoshandisa mweya semhepo yekutonhodza.Iyo firiji inonyungudutswa mupombi, uye mweya unoyerera kunze kwepombi kuti utore kupisa kunoburitswa nemhute yefiriji mupombi.Nekuda kwekudzikira kwekupisa kwemhepo, zvimbi zvinowanzogadzikwa kunze kwechubhu (parutivi rwemhepo) kuti uwedzere kupisa kunze kwechubhu.Kune marudzi maviri emhepo isina kuyerera uye mhepo inomanikidzwa kuyerera.
1. Mhepo inotonhodza condenser ine kuyerera kwemhepo mahara:
Iyo condenser inoshandisa mweya unoyerera kunze kwechubhu kutora kupisa kunoburitswa nefiriji.Shanduko yehutsigiro inokonzera kuyerera kwemhepo yakasununguka uye inogara ichibvisa kupisa kwekupisa kwehupfu hwefiriji.Iyo haidi fan, hapana ruzha, yakawanda inoshandiswa mudiki mafiriji zvikamu.Sezvakaratidzwa mumufananidzo uri pasi apa:
Mhepo yakatonhodzwa condenser ine mhepo yekumanikidzira kuyerera: Sezvinoratidzwa pamufananidzo uri pazasi, ine imwe kana akawanda seti yemachubhu ane nyoka ane zvimbi.Iyo refrigerant vapor inopinda muhubhu yenyoka kubva kumuunganidzi wepamusoro, uye iyo yekunze fin yechubhu inoshandiswa kusimbisa mhepo yemhepo yekupisa kupisa uye kutsiva iyo yakaderera yekupisa coefficient yemhepo.
Mukutaura kwechimiro, iyo yakawanda mitsara yechubhu pamwe chete negwaro rekuyerera kwemhepo, iyo idiki yekupisa kupisa kwemutsara wekumashure, kuitira kuti simba rekutamisa kupisa harigone kushandiswa zvizere.Kuti uvandudze chiyero chekushandiswa kwenzvimbo yekutsinhanisa kupisa, zviri nani kusarudza mitsara 4-6 yepombi.
2. Kuenzanisa pakati pemhepo yakatonhodzwa condenser nemvura yakatonhodzwa condenser:
(1) Munzvimbo dzine mvura yekutonhodza inokwana, mari yekutanga uye mari yekushandisa yemidziyo inotonhodzwa nemvura yakaderera pane yemidziyo inotonhodzwa nemhepo;
(2) Nekuda kwekushisa kwekunze kwekunze kwemhepo muzhizha, tembiricha yekudziya inogona kusvika makumi mashanu.℃.Kuti uwane kutonhora kwakafanana, simba refiriji compressor yemhepo-yakatonhodzwa michina inoda kuwedzerwa ne15%;
(3) Sitimu yemidziyo yefiriji inoshandisa air cooled condenser iri nyore, iyo inogona kuderedza kushomeka kwemvura;
Tatu, evaporative condenser
1. Evaporative condenser:
Nemvura nemhepo semhepo yekutonhora.Inoshandisa evaporation yemvura kutora kupisa kuti iite condence refrigerant mhute mupombi.Mvura inosimudzwa nepombi yobva yapfapfaidzwa ichienda kunze kwechubhu yekutamisa kupisa nemuromo kuti igadzire firimu remvura.Chikamu chemvura chinotora kupisa chinoputika muhutsi hwemvura, uye chinotorwa nemhepo inopinda mucondenser.
Madonhwe emvura asingaputsi anowira mudziva riri pazasi.Bhani remvura rakarongwa pamusoro pebhokisi rebhokisi.Inoshandiswa kudzivirira madonhwe emvura kuti asapunyuka mumhepo.Chimiro chechimiro che evaporative condenser inoratidzwa mumufananidzo.
2. Hunhu hwe evaporative condenser:
(1) Kushandisa mvura vaporization kubvisa condensation kupisa, mvura inotonhorera inopedzwa inongova yakarasika mvura recharge, kutonhora kushandiswa kwemvura idiki;
(2) The inlet air wet bulb tembiricha ye evaporative condenser ine simba guru pakutsinhana kwekupisa.Kune imwecheteyo tembiricha yekudziya uye vhoriyamu yemhepo, iyo idiki tembiricha yegirobhu yakanyorova, ndiko kukura kwekubuda kwemvura inotonhorera, uye zvirinani kuita kuti condensation iite.
(3) Evaporative condenser ine mvura shoma inoshandiswa, uye mweya unodiwa uri pasi pe 1/2 yemhando yemhepo yakatonhodzwa, saka inonyanya kukodzera nzvimbo dzakaoma dzine kushomeka kwemvura.
