Mumayuniti anotonhorera mhepo inotonhora,nyungudutsa machubhu ekudziyisa(kana kuti maheaters ekunyungudutsa) ndizvo zvinhu zvikuru zvinoita kuti hurongwa hwekutonhodza hushande zvakanaka. Zvinogadzirisa zvakananga kuderera kwekushanda kunokonzerwa nekuungana kwechando pa evaporator. Maitiro ekushanda kwavo uye kukosha kwavo zvinogona kupfupikiswa nenzira inotevera:
Ⅰ. Basa Guru: Kunyungudutsa nechando kuti uve nechokwadi chekuti firiji inoshanda zvakanaka
1. Bvisa Kuvharika kweFrost
*** Chikonzero Chedambudziko: Kana mudziyo wemhepo inotonhodza/inotonhodza mweya uchishanda, tembiricha yepamusoro pemapaini emvura inoputika iri pasi pe0°C. Mhute yemvura iri mumhepo inozopinda muchando yokora zvishoma nezvishoma (kunyanya munzvimbo dzine hunyoro hunopfuura 70%).
*** Migumisiro:
~ Chando chinofukidza mapepi chinotadzisa kufamba kwemhepo → Huwandu hwemhepo hunoderera ne30% kusvika 50%.
~ Chigadziko chechando chinoumba chikamu chinodzivirira kupisa → Kushanda zvakanaka kwekutsinhana kwekupisa kunoderera neanopfuura 60%.
~ Compressor inomanikidzwa kushanda kwenguva yakareba nekuda kwekudzikira kwesimba remhepo rinodzoka → kuwedzera kwekushandiswa kwesimba.
*** Mhinduro yechubhu yekudziyisa:
Mushure mekunge simba rashandiswa, pamusoro penyungudutsa chubhu yekudziyisainokwira kusvika 70 - 120℃, ichinyungudutsa chando chiri pakati pemafin → ichidzorera nzira yemhepo uye ichivandudza kushanda zvakanaka kwekuchinjana kwekupisa.
2. Kudzivirira kuvharika kwechando muhurongwa hwemvura inoyerera
*** Panorwadza zvikuru: Kana pombi yekudonhedza mvura iri pasi pefeni inotonhodza ikaoma uye yakavharwa, mvura inonyungudutsa ichadzokera mudura remvura yooma, zvichikonzera njodzi dzekuchengetedza.
*** Kushandiswa kwechubhu yekudziya:
Putira waya yekudziyisa ye silicone rabber drain tambo uchitenderedza pombi yekudonhedza mvura (ine simba re40-50W/m2), uchichengetedza tembiricha yepombi iri pamusoro pe5℃ → Iva nechokwadi chekuti mvura inonyungudutsa inogona kuburitswa zvakanaka.
Ⅱ. Kushanda pamwe chete kweWork Logic neSistimu
1. Nzira yekubvisa chando
*** Kudzora Nguva: Tanga kunyungudutsa zvichienderana nedanho rawakaronga (semuenzaniso, nyungudutsa kamwe chete mumaawa matanhatu ega ega);
*** Kunzwa tembiricha: Sensor yekupisa pamusoro pechinhu chinobuda mumhepo inoyerera inoona ukobvu hwechando. Kana muganhu wasvika, kunyungudika kunotanga.
*** Kudzora musiyano wekumanikidzwa: Tarisa musiyano wekumanikidzwa pakati pemativi maviri e evaporator. Kana musiyano wacho ukapfuura muganho, zvinoratidza kuti mhepo haipindi zvakanaka uye kunyungudika kunodiwa.
2. Maitiro Ekunyungudutsa
Ⅲ. Zvimiro zveDhizaini uye Kuenderana neCold Storage
| Hunhu | Zvinodiwa pakushandisa Cold Storage Application | Kushandiswa kweChirongwa cheKudziisa Tubhu reDefrost |
| Kuchinjika Kwekupisa Kwakaderera | Inofanira kunamatira zvakasimba kumafin patembiricha iri pasi pe -30℃ | Rutivi rwekunze rwesilicone rwakapfava runochengetedza kuchinjika, hapana njodzi yekutyoka panguva yekumisikidzwa kwemhepo |
| Kuvhara Kunodzivirira Hunyoro | Hunyoro hwakanyanya (hunyoro hwakafanana munzvimbo inotonhorera > 90%) | Kudzivirira silicone ine mativi maviri + majoini akaumbwa, chiyero chemvura chiri pamusoro pe IP67 |
| Kudzora Tembiricha Kwakarurama | Inodzivirira kupisa zvakanyanya kukuvadza zvinhu zvealuminium | Fuse yekupisa yemukati (nzvimbo yekunyunguduka 130℃) kana chinodzora tembiricha yekunze |
| Kuramba Kuora | Haipindi mumvura uye munzvimbo inotonhorera | Muenzaniso wesimbi isina ngura ine fluorine kana 316 (yekuchengetera zvinhu zvinotonhora nemakemikari) |
Ⅳ. Mabhenefiti Akananga uye Kukosha Kusina Kunanga
1. Kuchengetedza Simba uye Kuderedza Mari
*** Kunyungudutsa nechando panguva yakakodzera kunodzosera kushanda kwefiriji kusvika pamusoro pe95%, kunopfupisa nguva yekushanda kwecompressor → Kushandiswa kwesimba rose kunoderedzwa ne15% kusvika 25%.
*** Nyaya: Firiji ye -18℃ payakatadza kubvisa chando nenguva, kushandiswa kwemagetsi pamwedzi kwakawedzera nemayuniti 8,000. Mushure mekuisa machubhu ekupisa, yakadzokera kune yakajairika.
2. Iva nechokwadi chekuti zvinhu zvakachengeteka
*** Kuchinjana kwekupisa kwakanaka kwemuchina we evaporator → Kuchinja-chinja kwekupisa munzvimbo yekuchengetera kuri mukati me ±1℃ → Kudzivirira zvigadzirwa zvakachengetwa nechando kuti zvisanyungudike uye kuora kana kukuvadza chimiro chemasero nemakristaro echando.
3. Wedzera hupenyu hwemidziyo
*** Kuderedza kushanda kwecompressor nguva nenguva uye kushanda kwecompressor ine mutoro wakawanda → Hupenyu hwezvinhu zvakakosha hunogona kuwedzerwa nemakore matatu kusvika mashanu;
*** Kudzivirira kuputika kwechando mumapombi emvura → Kuderedza njodzi yekubuda kwemvura mufiriji.
Ⅴ. Pfungwa huru dzekusarudza nekugadzirisa
1. Kuenzanisa kuwanda kwesimba
*** Chinotonhodza mweya chisina kureruka: 30 - 40W pamita imwe neimwe (nemukana uri pakati pemafin > 5mm);
*** Mhepo inotonhorera yemumaindasitiri ine simba guru: 45 - 60W pamita imwe neimwe (kupisa kwakanyanya kunodiwa kuti mapapiro akasimba apinde).
2. Magadzirirwo Ekuisa
*** Machubhu ekudziyisa ekudziyisa anoshandiswa mukudziyisa anofanira kugoverwa zvakaenzana pakati pemafin, nzvimbo yacho isingapfuure 10 cm (kudzivirira kuti nzvimbo dzese dzisave nechando chakanyunguduka).
*** Waya inotonhora inofanira kuchengetwa ne 20 cm, uye nzvimbo dzekubatanidza dzinofanira kuvharwa ne silicone gel isingatsvedzeri kupisa zvakanyanya.
3. Kudzivirira Mhosva
*** Gara uchiyedza kudzivirira kuputira (>200MΩ) kudzivirira kubuda kwemvura.
*** Chenesai mafin eguruva gore rega rega kudzivirira kuungana kweguruva, izvo zvinoderedza kushanda zvakanaka kwekutapurirana kwekupisa.
Chinhu chinodziya chefriji chinodziisa chando chinoita basa re "system guardian" mumhepo inotonhorera yemuchengetedzi wechando:
Panyama: Inopwanya chando, inodzoreredza nzira yekuchinjisa kupisa;
Zvehupfumi: Kuburikidza nekuchengetedza simba uye kudzivirira kukanganisa, zvinoderedza zvakanyanya mari yekushandisa;
Tekinoroji: Kusanganiswa kwezvinhu zvesilicone uye kudzora tembiricha zvine hungwaru kunoita kuti nzira yekubvisa icing ive yakachengeteka uye chaiyo.
Pasina chubhu yekudziya inonyungudutsa chando, mhepo inotonhorera inotonhora yakaita seinjini yakaomeswa nechando panzvimbo yayo - inoita seiri kushanda, asi chaizvoizvo isina kushanda zvakanaka.
