Iko kuumbwa kwenzvimbo inotonhora yekuchengetera yakakamurwa kuita zvikamu zvishanu: inotonhora yekuchengetera unit, inotonhorera yekuchengetedza bhodhi (kusanganisira inotonhora yekuchengetera gonhi), evaporator, bhokisi rekugovera, pombi yemhangura.
Cold storage
1. Ngatitaurei nezve bhodhi rekuchengetedza inotonhora kutanga:
Iyo inotonhora yekuchengetera bhodhi inoumbwa neyekunze layer zvinhu uye yemukati layer zvinhu. Ukobvu hwebhodhi rekuchengetedza inotonhora hwakakamurwa kuita marudzi mashanu: 75mm, 100 mm, 120 mm, 150 mm, uye 200mm.
Iyo yekunze layer zvinhu yakakamurwa kuita mhando nhatu: ruvara simbi ndiro, embossed aluminium ndiro, Baosteel ndiro, uye Stainless simbi ndiro. Ukobvu hwekunze kwechifukidzo chakakamurwa kuita 0.4mm, 0.5mm, nezvimwewo. Iyo yemukati layer inogadzirwa ne polyurethane foam.
Iyo inowanzo shandiswa inotonhora yekuchengetera bhodhi ndeye 100 mm, iyo inoumbwa ne0.4mm gobvu ruvara simbi ndiro pamwe ne polyurethane furo. Iyo yakakora iyo inotonhora yekuchengetedza bhodhi, zviri nani iyo insulation mhedzisiro. Iyo inotonhora yekuchengetedza bhodhi inogona kugadziriswa maererano nezvinodiwa nevatengi.
Kune marudzi matatu emagonhi ekuchengetera anotonhora: magonhi anotsvedza, magonhi anotsvedza, uye magonhi maviri. Saizi uye ukobvu hwegonhi, bhodhi, nezvimwe zvinogona kugadzirwa zvinoenderana nezvinodiwa nevatengi.
2. Cold room condensing unit:
Maitiro ekushanda kwekamuri inotonhora yefiriji system inoumbwa ne compressor—> condenser—> liquid tangi yekuchengetera—> filter—> expansion valve—> evaporator.
Kune mhando dzakawanda dzecompressor: Copeland (USA), Bitzer (Germany), Sanyo (Japan), Tecumseh (France), Hitachi (Japan), Daikin (Japan), Panasonic (Japan).
Saizvozvo, mhando dzefiriji dzinowedzerwa kune imwe neimwe compressor dzakasiyana, kusanganisira R12, R22, R134a, R404a, R410a, R600.
Pakati pavo, R134a, R404a, R410a, uye R600 mafiriji ane ushamwari. , Iwo anomanikidza kukosha akawedzerwa kune akasiyana mafiriji akasiyana zvakare.
1. Basa re condenser nderokubvisa kupisa kwe compressor.
Kana iyo condenser yakasviba zvakanyanya, kana iyo inotonhora yekuchengetera unit yakaiswa munzvimbo ine urombo kupisa kupisa, inokanganisa zvakananga mhedzisiro yefiriji yekuchengetedza inotonhora. Saka, mumamiriro ezvinhu akajairika, condenser inoda kucheneswa kamwe chete pamwedzi mitatu yega yega, uye iyo inotonhora yekuchengetedza unit inofanira kuiswa munzvimbo ine mhepo inofefetera inoenderana nekupisa kupisa.
2. Basa remvura yekuchengetedza tangi ndeyekuchengetedza refrigerant yemvura
Kana iyo firiji system iri kushanda, compressor inomanikidza gasi kune condenser kuti iparadze kupisa, uye refrigerant yemvura uye gaseous refrigerant inoyerera pamwechete muhubhu yemhangura. Panguva ino, kana paine yakawandisa yemvura refrigerant, iyo yakawandisa ichachengetwa mumvura yekuchengetedza tangi. Kana iyo refrigerant yemvura inodiwa mufiriji iri shoma, tangi yekuchengetera mvura inongozvizadza.
3. Basa resefa nderokusefa tsvina
Iyo sefa ichasefa kunze kwemarara kana kusvibiswa kunogadzirwa ne compressor uye mhangura chubhu panguva yefiriji, senge guruva, unyoro, etc. Kana pasina firiji, marara aya achavhara capillary kana kuwedzera kwevhavha, zvichiita kuti sisitimu isakwanise kuita firiji. Kana mamiriro acho akakomba, kuderera kwakaderera kuchava kudzvinyirira kusina kunaka, izvo zvichaita kukanganisa kune compressor.
4. Varuvhu yekuwedzera
Thermostatic expansion valve inowanzoiswa pamusuwo we evaporator, saka inonzi valve yekuwedzera. Ine mabasa makuru maviri:
①. Kutendeuka. Mushure mokunge kutonhora kwepamusoro-kupisa uye kudzvinyirira kwemvura yefiriji ichipfuura nepakati pegomba rekushandura kwevhavha yekuwedzera, inova yakadzika-kupisa uye yakadzika-inodzvinyirira mhute-yakafanana ne hydraulic refrigerant, ichigadzira mamiriro ekubuda kwefiriji.
②. Dzora kuyerera kwefiriji. Iyo yemvura refrigerant inopinda muevaporator inoputika kubva kumvura kuenda kune gasi mushure mekupfuura nemuevaporator, inotora kupisa, uye inoderedza tembiricha munzvimbo inotonhora. Ivhavha yekuwedzera inodzora kuyerera kwefiriji. Kana iyo inoyerera yakawandisa, iyo yekubuda ine mvura refrigerant, iyo inogona kupinda mucompressor kukonzera kuunganidzwa kwemvura. Kana kuyerera kuri kudiki, iyo evaporation inopedzwa pachine nguva, izvo zvinokonzeresa kusakwana kwefiriji ye compressor.
3. Evaporator
Evaporator imhando yemadziro-mhando yekutsinhanisa kupisa mudziyo. Iyo yakaderera-yekushisa uye yakaderera-inodzvinyirira mvura refrigerant inopfungaira uye inotora kupisa kune rumwe rutivi rwekupisa kutamisa madziro eevaporator, nekudaro kutonhora svikiro kune rumwe rutivi rwemadziro ekutamisa kupisa. Iyo yakatonhodzwa yepakati inowanzova mvura kana mhepo.
Naizvozvo, evaporators inogona kukamurwa kuita mapoka maviri. Evaporator inotonhodza zvinwiwa uye maevaporator anotonhorera mweya. Mazhinji anotonhora ekuchengetedza evaporator anoshandisa yekupedzisira.
4. Bhokisi remagetsi
Bhokisi rekugovera rinoda kubhadhara kune nzvimbo yekuisa. Kazhinji, bhokisi rekugovera richaiswa padivi pegonhi rekuchengetera rinotonhora, saka tambo yemagetsi inotonhora inowanzo shongedzerwa 1-2 metres padivi pegonhi rekuchengetedza inotonhora.
5. Pipe yemhangura
Zvinofanira kuonekwa pano kuti urefu hwepombi yemhangura kubva kune inotonhora yekuchengetedza unit kusvika kune evaporator inofanira kudzorwa mukati me15 mamita. Kana iyo pombi yemhangura yakareba, inokanganisa firiji.
