1. Ukwethulwa kwamayunithi okuqandisa ahambisanayo
Iyunithi ehambisanayo ibhekisela kuyunithi yokuqandisa ehlanganisa ama-compressor angaphezu kwamabili ku-rack eyodwa futhi ikhonza ama-evaporator amaningi. Ama-compressor anomfutho ofanayo wokuhwamuka kanye nomfutho wokujiya, futhi iyunithi ehambisanayo ingakwazi ukulungisa amandla ngokuzenzakalelayo ngokuya ngomthwalo wesistimu. Ingakwazi ukufeza ukuguguleka okufanayo kwe-compressor, futhi iyunithi yokuqandisa ithatha indawo encane, futhi kulula ukwenza ukulawula okuphakathi kanye nokulawula okude.
Isethi efanayo yamayunithi ingakhiwa uhlobo olufanayo lwama-compressor, noma izinhlobo ezahlukene zama-compressor. Ingakhiwa uhlobo olufanayo lwe-compressor (njengomshini we-piston), noma ingakhiwa izinhlobo ezahlukene zama-compressor (njengomshini we-piston + umshini wesikulufu); ingalayisha izinga lokushisa elilodwa lokuhwamuka noma amazinga okushisa ahlukahlukene okuhwamuka. Izinga lokushisa; kungaba uhlelo lwesigaba esisodwa noma uhlelo lwezigaba ezimbili; kungaba uhlelo lomjikelezo owodwa noma uhlelo lwe-cascade, njll. Iningi lama-compressor avamile yizinhlelo ezifanayo zomjikelezo owodwa.
Amayunithi e-compressor ahambisanayo afanelana kangcono nomthwalo wokupholisa onamandla wesistimu yokuqandisa. Ngokulungisa ukuqala nokuma kwe-compressor ohlelweni lonke, isimo "sehhashi elikhulu nenqola encane" siyagwenywa. Isibonelo, lapho isidingo samandla okupholisa siphansi ebusika, i-compressor ivulwa kancane, kanti ehlobo, isidingo samandla okupholisa sikhulu, kanti i-compressor ivulwa kakhulu. Ingcindezi yokumunca yeyunithi ye-compressor igcinwa ingaguquki, okuthuthukisa kakhulu ukusebenza kahle kwesistimu. Ukuhlolwa okuqhathanisayo kweyunithi eyodwa kanye neyunithi ehambisanayo kwenziwe ohlelweni olufanayo, futhi uhlelo lweyunithi ehambisanayo lungasindisa amandla ngo-18%.
Zonke izilawuli zama-compressor, ama-condenser nama-evaporator zingagxila ebhokisini lokulawula likagesi lesistimu, futhi izilawuli zekhompyutha zingasetshenziswa ukukhulisa ukusebenza kahle kwesistimu. Ngokuyisisekelo, ukusebenza okuphelele ngaphandle komuntu kanye nokusebenza kude kungafezwa.
2. Isiqondiso sepayipi kanye nokukhethwa kobubanzi bepayipi
Isiqondiso sephayiphi: Kuhlelo lokuqandisa lwe-Freon, uwoyela wokugcoba we-compressor ujikeleza ohlelweni kanye ne-refrigerant, ngakho-ke ukuze kuqinisekiswe ukubuya kwamafutha okubushelelezi kohlelo, iphayiphi yomoya obuyayo (iphayiphi yokucindezela okuphansi) kumele ibe nomugqa othize obheke kwi-compressor, ngokuvamile onomthambeka ongu-0.5%.
Ukukhetha ububanzi bepayipi: Uma ububanzi bepayipi yethusi buncane kakhulu, ukulahlekelwa yingcindezi yesiqandisi epayipini lokuphakelwa koketshezi (ipayipi lokucindezela okuphezulu) kanye nepayipi legesi elibuyayo (ipayipi lokucindezela okuphansi) kuzoba kukhulu kakhulu; Uma inani likhulu kakhulu, yize ukulahlekelwa ukumelana epayipini kungancishiswa, kuzobangela ukwanda kwezindleko zokutshalwa kwezimali kokuqala, futhi ngesikhathi esifanayo, kuzophinde kubangele isivinini esinganele sokubuya kukawoyela epayipini lomoya elibuyayo.
Isimiso sokukhetha ububanzi bepayipi esiphakanyisiwe: ijubane lokugeleza kwesiqandisi epayipini lokuphakelwa koketshezi lingu-0.5-1.0m/s, elingadluli u-1.5m/s; epayipini lomoya obuyayo, ijubane lokugeleza kwesiqandisi epayipini elivundlile lingu-7-10m/s, ijubane lokugeleza kwesiqandisi epayipini elikhuphukayo lingu-15~18m/s.
Umklamo wohlobo lwegatsha: Kukhona izihloko zokuphakelwa koketshezi kanye nezinhloko zomoya ezibuyayo kuyunithi ehambisanayo, futhi kunezigaba eziningi zokuphakelwa koketshezi kusihloko sokuphakelwa koketshezi, futhi igatsha elilodwa lomoya elibuyayo elihambisana negatsha ngalinye lokuphakelwa koketshezi liqoqwe ku-On the return air header, ipayipi lesistimu yokuqandisa leyunithi ehambisanayo libizwa ngokuthi uhlobo lwegatsha. Iqembu ngalinye lamagatsha, okungukuthi, igatsha lokuphakelwa koketshezi kanye negatsha lalo lokuphakelwa komoya elihambisanayo, lingaba ne-evaporator eyodwa (igatsha 1) noma iqembu lama-evaporator (igatsha n). Uma kuyiqembu lama-evaporator, ngokuvamile iqembu lama-evaporator liqala futhi lime ngesikhathi esifanayo.
I-evaporator iphakeme kune-compressor:
Uma i-evaporator iphakeme kune-compressor, inqobo nje uma umugqa wokubuyisa unomthambeka othile futhi ukhetha ububanzi bepayipi obufanele, uhlelo lungaqinisekisa ukubuya kukawoyela okubushelelezi. Kodwa-ke, uma umehluko wokuphakama phakathi kwe-evaporator ne-compressor mkhulu kakhulu, i-liquid refrigerant epayipini lokuhlinzeka ngoketshezi izokhiqiza umusi we-flash ngaphambi kokufinyelela indlela yokupholisa kakhulu.
I-evaporator iphansi kune-compressor:
Uma i-evaporator iphansi kune-compressor, i-refrigerant epayipini lokuphakelwa koketshezi ngeke ikhiqize umusi okhanyayo ngenxa yomehluko wokuphakama phakathi kwe-evaporator ne-compressor, kodwa lapho kuklanywa ipayipi lesistimu yokuqandisa, ukubuya kwesistimu kumele kucatshangelwe ngokugcwele. Inkinga kawoyela, ngalesi sikhathi, ukugoba kokubuya kukawoyela kufanele kuklanywe futhi kufakwe engxenyeni ekhuphukayo yegatsha ngalinye lomoya obuyayo.
I-evaporator iphakeme kune-compressor:
Uma i-evaporator iphakeme kune-compressor, inqobo nje uma umugqa wokubuyisa unomthambeka othile futhi ukhetha ububanzi bepayipi obufanele, uhlelo lungaqinisekisa ukubuya kukawoyela okubushelelezi. Kodwa-ke, uma umehluko wokuphakama phakathi kwe-evaporator ne-compressor mkhulu kakhulu, i-liquid refrigerant epayipini lokuhlinzeka ngoketshezi izokhiqiza umusi we-flash ngaphambi kokufinyelela indlela yokupholisa kakhulu.
I-evaporator iphansi kune-compressor:
Uma i-evaporator iphansi kune-compressor, i-refrigerant epayipini lokuphakelwa koketshezi ngeke ikhiqize umusi okhanyayo ngenxa yomehluko wokuphakama phakathi kwe-evaporator ne-compressor, kodwa lapho kuklanywa ipayipi lesistimu yokuqandisa, ukubuya kwesistimu kumele kucatshangelwe ngokugcwele. Inkinga kawoyela, ngalesi sikhathi, ukugoba kokubuya kukawoyela kufanele kuklanywe futhi kufakwe engxenyeni ekhuphukayo yegatsha ngalinye lomoya obuyayo.
