Chigadziko chekuchengetedza chinotonhorera (cold storage parallel unit) chinoreva chigadziko chefriji chinoumbwa nemacompressor maviri kana anopfuura ane seti yezvikamu zvefiriji zvakafanana. Zvichienderana nefirijitembiricha nekukwanisa kutonhora pamwe nekusanganiswa kwemakondensa, mayuniti akafanana anogona kuva nemafomu akasiyana.
Chigadzirwa chimwe chete chinogona kuumbwa nemacompressor emhando imwe chete kana marudzi akasiyana emacompressor. Chinogona kuumbwa nemhando imwe chete yemacompressor (senge muchina wepiston),kanainogona kuumbwa nemhando dzakasiyana dzecompressor (senge muchina wepiston + muchina we screw); Inogona kurodha tembiricha imwe chete yekubuda kwemvura kana kubhururuka kwakasiyana-siyanatembiricha; inogona kuva sisitimu ine nhanho imwe chete kana sisitimu ine nhanho mbiri; inogona kuva sisitimu ine nhanho imwe chete kana sisitimu ye cascade, nezvimwewo. Ma compressor akajairika anowanzova e cycle imwe chetemasisitimu akafanana akafanana.
Kune nzvimbo diki nepakati dzekuchengetera zvinhu zvinotonhora, muchina wekuscrolla mudiki kwazvo, muchina wekuskurura unodhura zvakanyanya kuti ubatanidzwe panguva imwe chete, fomura yepiston ine mwero, uyeiyomutengo ndiwo wakanyanya kukwira.

Ndezvipi zvakanakira zvemayuniti akafanana?
1) Chimwe chezvakanakira zviri pachena zvemayuniti akafanana ndeyekuvimbika kwakanyanya. Kana compressor iri muyuniti ikakundikana, mamwe macompressor anogona kuramba achishanda zvakajairika. Kana stand-mudziyo wega wega unokundikana, kunyangwe dziviriro diki yekumanikidza inoidzivirira kubva pakuvharwa. Nzvimbo yekuchengetera inotonhora inenge yaoma, zvichikonzera njodzi kumhando yezvinhu zvakachengetwa mumotokari.Hapana imwe nzira yekuenda nayo kungomirira kugadziriswa.
2) Imwe mukana uri pachena wezvikamu zvakafanana ndeyekushanda zvakanaka uye mari shoma yekushandisa. Sezvatinoziva tese, sisitimu yekutonhodza ine macompressor zvinoenderana nemamiriro ezvinhu akaipisisa. Kutaura zvazviri, sisitimu yekutonhodza inoshanda pamamiriro ezvinhu ehafu yenguva zhinji. Mumamiriro ezvinhu akadaro, kukosha kweCOP yeyuniti yakafanana kunogona kuverengerwa nguva yesenechimiro chemutoro wakazara. Panguva imwe chete, kukosha kweCOP kweyuniti imwe chete panguva ino kuchaderedzwa nehafu. Mukuenzanisa kwakazara, yuniti yakafanana inogona kuchengetedza30-50% yemagetsi kupfuura unit imwe chete.
3) Kushanda nesimba zvakanyanya uye kuchengetedza simba, kudzora kugona kunogona kuitwa muzvikamu, kuburikidza nekusanganiswa kwemacompressor akawanda, matanho ekugadzirisa simba ane zvikamu zvakawanda anogona kuitwa.kana zvapihwa, uye chiller output yeyuniti inogona kuenderana nezvinodiwa chaizvo. Macompressor akawanda anogona kuva nehukuru hwakasiyana kuti aenzane nemutoro chaiwo zviri nyore,nokudaro tichiwana simba rakanakisisa rekugadzirisa shanduko yemutoro, kuvandudza kushanda zvakanaka uye kuchengetedza simba.
4) Zvikamu zvakafanana zvine dziviriro yakakwana, kazhinji zvine seti yakazara yemamodule edziviriro ekuchengetedza anosanganisira kurasikirwa kwechikamu, kutevedzana kwemashure, overvoltage, undervoltage, oirikumanikidzwa, voltage yakakwira, voltage yakaderera, electronic level yakaderera, uye electronic motor overload.
5) Inopa kudzora kwebazi rine kufemerwa kwakawanda. Zvichienderana nezvinodiwa, yuniti imwe chete inogona kupa tembiricha dzakawanda dzinoita kuti mvura itsvuke, ichishandisa simba rekutonhodza rechinhu chimwe nechimwe chinobuda.tembiricha, kuitira kuti sisitimu ikwanise kushanda mumamiriro ezvinhu anochengetedza simba zvakanyanya.
