1. Ukwethulwa kwamayunithi wefriji ePharallel
Iyunithi elihambisanayo libhekisela kwiyunithi yesiqandisi elihlanganisa ama-compressors angaphezu kwamabili kwi-rack eyodwa futhi isebenza ama-evaporators amaningi. Abacindezeli banengcindezi evamile yokuhwamuka kanye nengcindezi yokuvutha kabusha, futhi iyunithi elifanayo lingashintsha ngokuzenzakalelayo amandla ngokusho komthwalo wohlelo. Ingabona ukugqokwa komfaniswano kwe-compressor, kanye neyunithi lesiqandisi lihlala endaweni encane, futhi kulula ukukuthola ukulawula okumaphakathi nokulawulwa okukude.
Isethi efanayo yamayunithi ingakhiwa ngohlobo olufanayo lwabacindezeli, noma izinhlobo ezahlukene zabacindezeli. Ingakhiwa ngohlobo olufanayo lwe-compressor (njengomshini we-piston), noma lungakhiwa ngezinhlobo ezahlukene zabacindezeli (njenge-piston umshini we-piston + screw Machine); Ingalayisha izinga lokushisa elilodwa noma amazinga okushisa ahlukahlukene okuhanjiswa. Lokushisa; Kungaba uhlelo lwesigaba esisodwa noma uhlelo lwesigaba ezimbili; Kungaba uhlelo olulodwa lomjikelezo noma uhlelo lwe-Cascade, njll. Iningi labacindezeli abajwayelekile liyizinhlelo ezi-wind-umjikelezo ezihambisanayo zohlobo olufanayo.
Amayunithi e-compressor afana nawo ahambelana kangcono nomthwalo wokupholisa oshukumisayo wohlelo lokuqapha. Ngokushintsha ukuqala nokuma kwe-compressor kulo lonke uhlelo, isimo "sehhashi elikhulu nenqola encane" siyagwenywa. Isibonelo, lapho umthamo wokupholisa ufuna uphansi ebusika, i-comprescessor ivulwa kancane, futhi ehlobo, isidingo sokupholisa sikhulu, futhi i-compressor ivuliwe. Ingcindezi yokumunca eyunithi ye-compressor igcinwa njalo, okuthuthukisa kakhulu ukusebenza kahle kohlelo. Ukuhlolwa kokuqhathanisa kweyunithi elilodwa kanye nophiko oluhambisanayo kwenziwa ohlelweni olufanayo, futhi uhlelo lweyunithi le-parallel lungagcina amandla ngo-18%.
Zonke izilawuli zabacindezeli, ama-condensers kanye nama-evaporators zingagxila ebhokisini lokulawula kagesi, futhi abalawuli bamakhompiyutha bangase basetshenziselwe ukukhulisa ukusebenza kahle kohlelo. Ngokuyisisekelo, ukusebenza okuphelele okungahleliwe nokusebenza okukude kungatholakala.
2. Ukulungiswa kwepayipi kanye nokukhethwa kobubanzi bepayipi
I-PIPELINE IQHAWULEKILE: Ohlelweni lokuhanjiswa kwe-freeon, i-compressor lubrollar uwoyela ijikeleza ohlelweni kanye nesiqandisi, ukuze kuqinisekiswe ukubuyiselwa kwamafutha abushelelezi (ipayipi eliphansi (ipayipi eliphansi) kumele kube nomthambeka othile obheke ku-0.5%.
Ukukhetha kwepayipi kwepayipi Uma inani likhulu kakhulu, yize ukulahleka kokumelana nepayipi kungancishiswa, kuzodala ukwanda kwezindleko zokutshala imali okuqala, futhi ngasikhathi sinye, kuzokwenza futhi isivinini sokubuyisa uwoyela esilwaneni epayipini yomoya.
Isimiso sokukhethwa kwepayipi esiphakanyisiwe: Ukuhamba kwesiqalo sefriji ku-Witshe Uketshezi Pipeline kungu-0.5-1.0m / s, hhayi ngaphezulu kwe-1.5m / s; Epayipini e-Return Air, i-Flow velocity yesiqandisi epayipi elivundlile lingu-7-10m / s, isivinini sokugeleza kwesiqandisi esiqandayo ku-pipeline ekhuphukayo yi-15 ~ 18m / s.
Idizayini yohlobo lwegatsha: Kukhona izihloko zokuhlinzekwa koketshezi futhi zibuyise izihloko zomoya engxenyeni efanayo, futhi kunamagatsha amaningi okuthenga angenayo egatsheni lokuthenga ngoketshezi, elihambisana ne-park yokuvukela phansi ye-liquid yomoya libizwa ngokuthi yi-Return Air Header, ipayipi eliyisiqandisi elinjalo libizwa ngokuthi yi-Pipeline Air Pipeline ngayinye. I-pash ngayinye yamagatsha, okungukuthi, igatsha lokuhlinzekwa koketshezi kanye negatsha layo elihambisanayo le-Air Return Branch, lingaba nomthengisi owodwa (igatsha 1) noma iqembu lama-evaporators (igatsha n). Lapho kuyiqembu lama-evaporators, imvamisa iqembu lama-evaporators liqala futhi liyeke ngasikhathi sinye.
I-Evaporator iphakeme kune-compressor:
Uma i-Evaporator iphakeme kune-compressor, inqobo nje uma umugqa wokubuya unomthambeka othile bese ukhetha ububanzi obufanelekile bepayipi, uhlelo lungaqinisekisa ukubuyiselwa kwamafutha abushelelezi. Kodwa-ke, uma umehluko wokuphakama phakathi kwe-evaporator kanye ne-compressor enkulu kakhulu, i-liquid regrindint epayipi lokuhlinzekwa koketshezi izokhiqiza i-flash Steal ngaphambi kokufika kwinqubo yokuphonsa. we-supercooling.
I-Evaporator iphansi kune-compressor:
Uma i-evaporator iphansi kune-compressor, esiqandisini epayipi lokuhlinzekwa koketshezi ngeke likhiqize i-flash Steam ngenxa yomehluko wokuphakama phakathi kwe-evaporator kanye ne-compressor, kepha lapho kuklanywa ngokuphelele. Inkinga kawoyela, ngalesi sikhathi, ukugoba okubuyayo kawoyela kufanele kwakhiwe futhi kufakwe engxenyeni ekhuphukayo yegatsha ngalinye lebuya.
