Iyunithi ehambisana nendawo yokugcina ebandayo ibhekisela kuyunithi yokuqandisa eyakhiwe ama-compressor amabili noma ngaphezulu abelana ngesethi yamasekethe okuqandisa ahambisanayo. Kuye ngokuthi ifriji ingakananiizinga lokushisa kanye nomthamo wokupholisa kanye nokuhlanganiswa kwama-condenser, amayunithi ahambisanayo angaba nezinhlobo ezahlukene.
Iyunithi efanayo ingakhiwa ama-compressor ohlobo olufanayo noma izinhlobo ezahlukene zama-compressor. Ingakhiwa uhlobo olufanayo lwe-compressor (njengomshini we-piston),nomaingakhiwa ngezinhlobo ezahlukene ze-compressor (njengomshini we-piston + umshini wesikulufu); Ingalayisha izinga lokushisa elilodwa lokuhwamuka noma ukuhwamuka okuhlukahlukene okuhlukahlukeneamazinga okushisa; kungaba uhlelo lwesigaba esisodwa noma uhlelo lwezigaba ezimbili; kungaba uhlelo lomjikelezo owodwa noma uhlelo lwe-cascade, njll. Ama-compressor avamile ikakhulukazi alomjikelezo owodwaizinhlelo ezifanayo zohlobo olufanayo.
Kwindawo yokugcina ebandayo encane nephakathi nendawo, umshini wokuskrola mncane kakhulu, umshini wesikulufu ubiza kakhulu ukuxhuma ngokulingana, ifomula yepiston iphakathi nendawo, futhiiizindleko ziphakeme kakhulu.

Yiziphi izinzuzo zamayunithi ahambisanayo?
1) Enye yezinzuzo ezisobala kakhulu zamayunithi ahambisanayo ukuthembeka okuphezulu. Uma i-compressor eyunithini yehluleka, amanye ama-compressor asengaqhubeka nokusebenza ngokujwayelekile. Uma i-stand-uma iyunithi eyodwa ihluleka, ngisho nokuvikelwa okuncane kokucindezela kuzoyivikela ekuvaleni. Indawo yokugcina ebandayo isesimweni sokukhubazeka, okusongela ikhwalithi yezimpahla ezigcinwe kuIndawo yokugcina izinto. Ayikho enye indlela esingahamba ngayo ukulinda nje ukulungiswa.
2) Enye inzuzo esobala yamayunithi ahambisanayo ukusebenza kahle okuphezulu kanye nezindleko zokusebenza eziphansi. Njengoba sonke sazi, uhlelo lokuqandisa luhlonyiswe ngama-compressor ngokushoizimo ezimbi kakhulu. Eqinisweni, uhlelo lokuqandisa lusebenza ngezimo zomthwalo oyingxenye isikhathi esiningi. Ngaphansi kwezimo ezinjalo, inani le-COP leyunithi ehambisanayo linganqunywa ngokuphelele.ngesimo somthwalo ogcwele. Ngesikhathi esifanayo, inani le-COP leyunithi eyodwa ngalesi sikhathi lizoncishiswa ngaphezu kwesigamu. Ekuqhathaniseni okuphelele, iyunithi ehambisanayo ingasindisa30-50% kagesi kuneyunithi eyodwa.
3) Ukusebenza kahle kakhulu nokonga amandla, ukulawulwa kwamandla kungenziwa ngezigaba, ngokuhlanganiswa kwama-compressor amaningi, izigaba zokulungisa amandla zezigaba eziningi zingaba khonauma kuhlinzekiwe, futhi umphumela wokushisa weyunithi ungafanelana nesidingo sangempela somthwalo. Ama-compressor amaningi angaba nobukhulu obuhlukene ukuze afane ngokuguquguqukayo nomthwalo wangempela ngokushelela kakhudlwana,ngaleyo ndlela kutholakale ukulungiswa kwamandla okungcono kakhulu kokushintsha komthwalo, kuthuthukiswe ukusebenza kahle futhi kongiwe amandla.
4) Amayunithi ahambisanayo anokuvikelwa okuphelele, ngokuvamile anesethi ephelele yamamojula okuvikela ukuphepha afaka phakathi ukulahleka kwesigaba, ukulandelana okuphambene, i-overvoltage, i-undervoltage, uwoyelaingcindezi, i-voltage ephezulu, i-voltage ephansi, izinga eliphansi le-elekthronikhi, kanye nokugcwala ngokweqile kwenjini kagesi.
5) Ihlinzeka ngokulawula kwegatsha okuphefumulelwe ngezindlela eziningi. Ngokwezidingo, iyunithi eyodwa ingahlinzeka ngamazinga okushisa amaningi okuhwamuka, kusetshenziswa ngempumelelo amandla okupholisa okuhwamuka ngakunye.izinga lokushisa, ukuze uhlelo lusebenze esimweni esonga amandla kakhulu.
