Iyo inotonhora yekuchengetera parallel unit inoreva firiji unit inoumbwa maviri kana anopfuura macompressor anogovera seti yemasekete efiriji mukuwirirana.Zvichienderana nefirijitembiricha uye kutonhora kugona uye musanganiswa wemacondensers, iwo akafanana mayuniti anogona kuve akasiyana siyana.
Iyo imwechete unit inogona kuumbwa nemacompressor emhando imwechete kana akasiyana marudzi emacompressor.Inogona kuumbwa nemhando imwechete ye compressor (senge piston muchina),kanainogona kuumbwa nemhando dzakasiyana dze compressor (senge piston muchina + screw muchina);Inogona kurodha tembiricha imwe chete evaporation kana akati wandei akasiyana evaporationtembiricha;inogona kuva imwe-nhanho system kana maviri-nhanho system;Inogona kuva imwe-kutenderera hurongwa kana cascade system, etc. The common compressors inowanzova imwe-kutendereramaparallel systems emhando imwe chete.
Kune diki uye yepakati-kutonhora kuchengetedza, muchina wekupurudzira idiki, screw muchina unodhura zvakanyanya kuti ubatanidze wakafanana, iyo piston formula ine mwero, uyethemutengo ndiwo wepamusoro.

Ndezvipi zvakanakira maparallel units?
1) Imwe yemabhenefiti akajeka ezvikamu zvakafanana kuvimbika kwakanyanya.Kana compressor muyuniti ikatadza, mamwe macompressor anogona kuramba achishanda zvakajairwa.Kana kumira-yega unit inotadza, kunyangwe diki diki chengetedzo inodzivirira kubva pakuvhara.Iyo inotonhora yekuchengetera iri munzvimbo yakaoma mitezo, ichiunza kutyisidzira kune kunaka kwezvinhu zvakachengetwa mustorage.Hapana imwe nzira yekuenda chete kumirira kugadziriswa.
2) Imwe mukana wakajeka wemayuniti akafanana ndeyekunyanya kushanda uye yakaderera mari yekushandisa.Sezvatinoziva tese, iyo firiji system inoshongedzerwa nemacompressors zvinoenderana nemamiriro akaipisisa.Muchokwadi, iyo firiji system inomhanya pahafu-mutoro mamiriro kazhinji yenguva.Pasi pemamiriro ezvinhu akadaro, kukosha kweCOP kweiyo parallel unit inogona kupedzerwa nguvaine yakazara-mutoro mamiriro.Panguva imwecheteyo, kukosha kweCOP kwechikamu chimwe chete panguva ino kuchaderedzwa neanopfuura hafu.Mukuenzanisa kwakazara, parallel unit inogona kuchengetedza30-50% yemagetsi pane imwechete unit.
3) Kushanda kwakanyanya uye kuchengetedza simba, kutonga kwesimba kunogona kuitwa mumatanho, kuburikidza nekubatanidzwa kweakawanda compressor, akawanda-nhanho ekugadzirisa simba matanho anogonayakapihwa, uye iyo chiller inobuda yeyuniti inogona kuenderana neiyo chaiyo mutoro kudiwa.Multiple compressor inogona kuva yehukuru hwakasiyana kuti ienderane nemutoro chaiwo zvakanyanya mushe,nokudaro nekuona iyo yakanyanya kunaka kugadzirisa simba rekuchinja kwemutoro, kuvandudza kugona uye kuchengetedza simba.
4) Parallel units dzine dziviriro yakawandisa, kazhinji ine yakazara seti yekuchengetedza kuchengetedza mamodule anosanganisira kurasikirwa kwechikamu, reverse sequence, overvoltage, undervoltage, mafuta.pressure, high voltage, low voltage, electronic low level, uye electronic motor overload.
5) Inopa akawanda-anofuridzira bazi rekutonga.Zvinoenderana nezvinodiwa, imwe unit inogona kupa akawanda evaporating tembiricha, ichishandisa zvakanaka kutonhora kweyega yega inoputikatembiricha, kuitira kuti sisitimu imhanye mune yakanyanya kuchengetedza simba.
