Chiwonetsero chofanana

1. Kuyambitsa kwa magawo ofanana firiji

Chigawo chofananacho chimatanthawuza kufinya kufinya komwe kumaphatikizanso zoposa zoponderezana ziwiri mu vack imodzi ndikukhala ndi anthu ophatikizika. Omwe amaphatikizana ndi kukakamiza komanso kukakamizidwa kogwirizana, ndipo gawo lofananalo limatha kusintha mphamvu molingana ndi katundu wa dongosolo. Itha kuzindikira kuvala yunifolome ya compresser, ndipo gawo la firiji limakhala malo ochepa, ndipo ndikosavuta kuzindikira zofunikira komanso kuwongolera kotheratu.

Magawo omwewo amatha kupangidwa ndi mtundu womwewo wa compressors, kapena mitundu yosiyanasiyana ya compressors. Itha kupangidwa ndi mtundu womwewo wa compressor (monga Piston makina), kapena itha kupangidwa ndi mitundu yosiyanasiyana ya compressors (monga pisitoni makina a piston); Itha kukhazikitsa kutentha kamodzi kapena kutentha kosiyanasiyana. Kutentha; Itha kukhala dongosolo limodzi kapena dongosolo la magawo awiri; Itha kukhala dongosolo lozungulira kapena dongosolo la Cascade, etc. Ambiri mwa mitundu wamba yofala ndi njira imodzi yofanana.

Magawo ophatikizira compressrar amafanana bwino ndi katundu wa chisanu cha firiji. Mwa kusintha chiyambi ndi kuyimilira kwa compresser mu dongosolo lonse, mkhalidwe wa "kavalo wamkulu ndi ngolo yaying'ono" amapewedwa. Mwachitsanzo, kukafuna kozizira kumakhala kochepa kwambiri, ndipo nthawi yachilimweko kumayatsidwa pang'ono, ndipo nthawi yachilimwe, kufunidwa kozizira ndikokulira, ndipo compressor yatsegulidwanso. Kutengera mphamvu kwa compressor unit kumasungidwa, komwe kumathandiza kwambiri dongosolo. Kuyeserera kofanana ndi gawo limodzi ndi kufanana komwe kumachitika pa kachitidwe komweko, ndipo makina ofanana nawo amatha kupulumutsa mphamvu ndi 18%.

Zowongolera zonse za compressors, kutsitsa ndi zisumbu zimatha kukhazikika m'bokosi lamagetsi, ndipo oyendetsa makompyuta atha kugwiritsidwa ntchito kukulitsa dongosolo la makina. Kwenikweni, kugwirira ntchito kosadziwika bwino komanso ntchito yakutali ikhoza kutheka.

Kuwongolera papaipiness: Mu firiji ya Free Steon, mafuta odzola mafuta m'dongosolo limodzi ndi firiji, kotero kuti patsani malo otsetsereka) kuyenera kukhala ndi malo otsetsereka, nthawi zambiri ndi malo otsetsereka, nthawi zambiri amakhala ndi 0,5%.

Kusankhidwa kwapakati: Ngati mtengo wake ndi wokulirapo, ngakhale kuti kutaya kwina kwamapaipi kumatha kuchepetsedwa, kumapangitsa kuwonjezeka kwa mtengo woyamba, ndipo nthawi yomweyo, zimayambitsanso kuthamanga kwa mafuta obwerera mlengalenga.

Mfundo yofananira yosankha: Velocity yoyenda ya firiji yowonjezerayo papaipeyo ili 0,5-1.0m / s, osapitilira 1.5m / s; Pobwerera mlengalenga, velocity ya mufiriji yoyambira ili papakati ndi 7-10m / s, velocity ya firiji yokwera pamapaipe yokwera ndi 15m / s.

Mapangidwe a mtundu wa nthambi: Pali maulendo amadzimadzi ndikubweza mitu ya mpweya pamutuwu, ndipo pali nthambi zingapo zomwe zimasungidwa mu mutu wamadzimadzi zimasonkhanitsidwa. Nthambi iliyonse, ndiye kuti nthambi yamadzimadzi ndi nthambi yake yofananira ndi ndege, imatha kukhala ndi evaporator imodzi (Nthambi 1) kapena gulu la a Evaporators (Nthambi). Ikakhala gulu la okwera, nthawi zambiri gulu la ozungulira limayamba ndikuyima nthawi yomweyo.

Wotulutsayo ndiwokwera kuposa compressor:
Ngati Evaporator ndi apamwamba kuposa compressor, bola ngati mzere wobwerera uli ndi malo otsetsereka ena ndikusankha mainchesi oyenera, dongosolo lingawonetsetse kuti mafuta abwerere. Komabe, ngati kulimidwe pakati pa evorator ndipo compressor ndi yayikulu kwambiri, yofiyira yamadzimadzi mu madzi ogulitsa masitepe idzakulitsa njira yopumira. za supercooling.

Wotulutsa ndi wotsika kuposa compressor:
Ngati EvaPorator ndi wotsika kuposa compressor, mufiriji yamadzimadzi isatuluke kutalika pakati pa evorator chifukwa chosinthana pakati pa Phiriline, koma kubwerera kwa dongosololi kukuganiziridwa. Vuto la mafuta, panthawiyi, kubweza mafuta kuyenera kukhazikitsidwa ndikuyika pa gawo lokwera nthambi iliyonse yobwerera.

Komabe, ngati kulimidwe pakati pa evorator ndipo compressor ndi yayikulu kwambiri, yofiyira yamadzimadzi mu madzi ogulitsa masitepe idzakulitsa njira yopumira. za supercooling.

Ngati EvaPorator ndi wotsika kuposa compressor, mufiriji yamadzimadzi isatuluke kutalika pakati pa evorator chifukwa chosinthana pakati pa Phiriline, koma kubwerera kwa dongosololi kukuganiziridwa. Vuto la mafuta, panthawiyi, kubweza mafuta kuyenera kukhazikitsidwa ndikuyika pa gawo lokwera nthambi iliyonse yobwerera.
