Yakasanganiswa nemuenzaniso wekutonhora kuchengetedza engineering kugadzirisa, ini ndichakuudza tekinoroji yekutonhora yekuchengetedza defrosting.
Kuumbwa kwemidziyo yekuchengetedza inotonhora
Iyo purojekiti ndeyekutsva-inochengetedza inotonhora yekuchengetera, inova yemukati yakaunganidzwa inotonhora yekuchengetera, ine zvikamu zviviri: yepamusoro-tembiricha inotonhora yekuchengetedza uye yakaderera-inotonhora yekuchengetera.
Yese inotonhora yekuchengetera inopihwa neatatu maJZF2F7.0 Freon compressor condensing units, iyo compressor modhi i2F7S-7.0 yakavhurika piston single-unit refrigeration compressor, kutonhora kwe9.3KW, simba rekuisa i4KW, uye kumhanya i600rpm. Iyo firiji iR22. Imwe yemayuniti ine basa rekuchengetedza kutonhora kwepamusoro-tembiricha, uye mamwe maviri mayuniti ane basa rekudzikira-kutonhora kwekuchengetedza. Iyo indoor evaporator inyoka coil yakasungirirwa kumadziro mana uye pamusoro peichengeterwa inotonhora. Iyo condenser inomanikidzwa mhepo yakatonhodzwa coil unit. Iko kushanda kweiyo inotonhora kuchengetedza inodzorwa neiyo tembiricha yekudzora module kutanga, kumisa uye kumhanya iyo firiji compressor zvinoenderana nepamusoro uye yakaderera miganho yekuseta tembiricha.
General mamiriro uye matambudziko makuru ekuchengetedza kutonhora
Mushure mekunge mudziyo wekuchengetera inotonhora waiswa mukushandiswa, zviratidzo zvekuchengetedza inotonhora zvinogona kuzadzisa zvinodiwa zvekushandisa, uye maparamendi ekushandisa emidziyo zvakare ari mukati meyakajairika renji. Zvisinei, mushure mokunge midziyo yave ichishanda kwenguva yakati, apo chando chechando pane coil inoputika inoda kubviswa, nekuda kwekugadzirwa Mushonga hauna otomatiki inotonhora yekuchengetedza defrosting mudziyo, uye chete bhuku rekuchengetedza kutonhora kwekuchengetedza kunogona kuitwa. Sezvo iyo coil iri kuseri kwemasherufu kana zvinhu, masherufu kana zvinhu zvinofanirwa kutamiswa kune yega yega defrosting, izvo zvakanyanya kunetsa, kunyanya kana paine zvinhu zvakawanda munzvimbo inotonhora. Basa rekubvisa chando rinotonyanya kuoma. Kana kugadziridzwa kwakakodzera kusingaitwe pane inotonhora yekuchengetera midziyo, inosungirwa kukanganisa zvakanyanya kushandiswa kwakajairwa kwekutonhora kwekuchengetedza uye kuchengetedza kwemidziyo.
Cold storage defrosting rectification plan
Tinoziva kuti kune nzira dzakawanda dzekudzikisa kutonhora kwekuchengetedza, zvakadai semagetsi ekugadzirisa, magetsi emagetsi, mvura yepfapfaidzo yemvura uye kupisa kwemhepo inopisa, nezvimwewo. Kupisa gasi defrosting ine hupfumi uye yakavimbika, iri nyore kuchengetedza uye kubata, uye mari yayo uye kuvaka haina kuoma. Nekudaro, pane zvakawanda zvinogadziriswa zvegasi rinopisa defrosting. Nzira yenguva dzose ndeyekutumira gasi repamusoro-soro uye rinopisa rinobudiswa kubva kune compressor kuenda kune evaporator kuti isunungure kupisa uye defrost, uye rega mvura yakanyungudutswa ipinde mune imwe evaporator kuti ibvise kupisa uye kunyunguduka mumhepo yakaderera uye yakaderera-pressure gasi. Dzokera kune compressor suction kuti upedze kutenderera. Tichifunga kuti chimiro chaicho chekuchengetedza inotonhora ndechekuti iwo matatu mayuniti anoshanda akazvimirira, kana matatu compressor achizoshandiswa anoenderana, akawanda maumbirwo akadai sekumanikidza kuenzana pombi, pombi dzekuenzanisa oiri, uye misoro yemhepo yekudzoka inofanira kuwedzerwa. Kuoma kwekuvaka uye huwandu hweinjiniya haisi diki. Mushure mekuratidzira kwakadzokororwa uye kuongororwa, zvakazosarudzwa kunyanya kutora musimboti wekutonhodza uye kupisa kushandurwa kwepombi yekupisa. Muchirongwa ichi chekugadzirisa, chivharo chechina chinowedzerwa kuti chizadzise shanduko yefiriji inoyerera inotungamirira panguva yekusvibiswa kwekuchengetedza kunotonhora. Munguva yekudzikisa, huwandu hukuru hwefiriji mumvura yekuchengetedza tangi pazasi pecondenser inopinda mucondenser, ichikonzera mvura sando chiitiko che compressor. Chivharo chekuongorora uye chivharo chekugadzirisa chinokonzera chinowedzerwa pakati pe condenser uye tangi yekuchengetedza mvura.Mushure mekugadzirisa, mushure memwedzi wekushanda kwekuedza, chiitiko chinotarisirwa chakanyatsogadziriswa pane zvose. Chete kana chando chakanyanya kukora (avhareji yechando chando> 10mm), kana nguva yekudzikisa iri mukati memaminitsi makumi matatu, iyo compressor dzimwe nguva ine isina kusimba Nekupfupisa defrosting kutenderera kwenzvimbo inotonhora yekuchengetera uye kudzora ukobvu hwechando chando, kuyedza kunoratidza kuti chero bedzi defrosting iri hafu yeawa pazuva, ukobvu hwechando huchapfuura 5mm uye kudzvanywa kwechando. liquid shock phenomenon haizoitike. Mushure mekugadziriswa kwemidziyo yekuchengetera inotonhora, kwete chete kugonesa zvakanyanya basa rekusvibisa rekuchengetedza inotonhora, asi zvakare yakavandudza kushanda kweiyo unit. Pasi pesimba rakafanana rekuchengetedza, nguva yekushanda yeyuniti yakaderedzwa zvakanyanya kana ichienzaniswa neyekare.
