Chigawo chofananira chosungirako chozizira chimatanthawuza gawo la firiji lopangidwa ndi ma compressor awiri kapena kupitilira apo omwe amagawana magawo a firiji mofanana.Malingana ndi firijikutentha ndi mphamvu yozizira komanso kuphatikiza kwa condensers, mayunitsi ofanana amatha kukhala ndi mitundu yosiyanasiyana.
Chigawo chomwecho chikhoza kupangidwa ndi ma compressor amtundu umodzi kapena mitundu yosiyanasiyana ya ma compressor.Itha kupangidwa ndi mtundu womwewo wa kompresa (monga makina a pistoni),kapenaimatha kupangidwa ndi mitundu yosiyanasiyana ya kompresa (monga piston machine + screw machine);Ikhoza kukweza kutentha kumodzi kwa nthunzi kapena mpweya wosiyanasiyanakutentha;ikhoza kukhala dongosolo limodzi kapena magawo awiri;Zitha kukhala dongosolo limodzi-mkombero kapena kutsika dongosolo, etc. The compressors wamba zambiri limodzi mkomberomachitidwe ofanana amtundu womwewo.
Posungirako kuzizira kochepa komanso kakang'ono, makina osindikizira ndi ochepa kwambiri, makina opangira ma screw ndi okwera mtengo kwambiri kuti asagwirizane nawo, mawonekedwe a piston ndi ochepa, ndipondimtengo ndi wapamwamba kwambiri.

Ubwino wa magawo ofanana ndi otani?
1) Ubwino umodzi wodziwikiratu wa magawo ofanana ndi kudalirika kwakukulu.Compressor mu unit ikalephera, ma compressor ena amatha kupitiliza kugwira ntchito moyenera.Ngati mayi-chokhacho chimalephera, ngakhale chitetezo chaching'ono chokakamiza chidzachiteteza ku shutdown.The ozizira yosungirako ali wolumala boma, poika chiwopsezo kwa khalidwe la katundu kusungidwa muyosungirako.Palibe njira ina yopitira kungodikirira kukonzedwa.
2) Ubwino wina wodziwikiratu wa mayunitsi ofanana ndikuchita bwino kwambiri komanso kutsika mtengo kogwiritsa ntchito.Monga ife tonse tikudziwa, firiji dongosolo okonzeka ndi compressors malinga ndimikhalidwe yoipitsitsa.M'malo mwake, firiji imagwira ntchito nthawi zambiri imakhala ndi theka.Pazifukwa zotere, mtengo wa COP wagawo lofananira ukhoza kukhazikitsidwa nthawi zonsendi katundu wodzaza.Panthawi imodzimodziyo, mtengo wa COP wa unit imodzi panthawiyi udzachepetsedwa ndi theka.Pakuyerekeza kwathunthu, gawo lofananira lingapulumutse30-50% yamagetsi kuposa unit imodzi.
3) Kuchita bwino kwambiri komanso kupulumutsa mphamvu, kuwongolera mphamvu kumatha kuchitika pang'onopang'ono, kudzera pakuphatikiza ma compressor angapo, magawo osinthira mphamvu yamagawo angapo amatha kukhalakuperekedwa, ndipo chiller linanena bungwe la unit akhoza zigwirizane kwenikweni katundu amafuna.Ma compressor angapo amatha kukhala amitundu yosiyanasiyana kuti agwirizane ndi katundu weniweniyo bwino,potero kuzindikira kusintha kwabwino kwamphamvu kwa kusintha kwa katundu, kukonza bwino komanso kupulumutsa mphamvu.
4) Magawo ofananira amakhala ndi chitetezo chokwanira, nthawi zambiri amakhala ndi ma module athunthu oteteza chitetezo kuphatikiza kutayika kwa gawo, kutsatizana, kuchulukirachulukira, kuperewera, mafutapressure, high voltage, low voltage, electronic low level, and electronic motor overload.
5) Amapereka maulamuliro a nthambi zambiri.Malinga ndi zosowa, gawo limodzi limatha kupereka kutentha kosiyanasiyana, mogwira mtima pogwiritsa ntchito kuzizirira komwe kumatulukakutentha, kotero kuti dongosolo likhoza kuthamanga mu chikhalidwe chopulumutsa mphamvu.
