1. Kutangwa kweParallel Refrigeration Units
Parallel unit inoreva refrigeration unit inobatanidza macompressor anopfuura maviri muraki imwe chete uye inoshandira ma evaporator akawanda. Macompressor ane evaporation pressure yakafanana uye condensation pressure, uye parallel unit inogona kugadzirisa otomatiki simba zvichienderana nemutoro wesystem. Inogona kuita kuti compressor ishande zvakafanana, uye refrigeration unit inogara munzvimbo diki, uye zviri nyore kuita centralized control uye remote control.
Seti imwe chete yemayuniti inogona kuumbwa nemhando imwe chete yemacompressor, kana mhando dzakasiyana dzemacompressor. Inogona kuumbwa nemhando imwe chete yecompressor (senge muchina wepiston), kana inogona kuumbwa nemhando dzakasiyana dzemacompressor (senge muchina wepiston + muchina wescrew); inogona kurodha tembiricha imwe chete ye evaporation kana tembiricha dzakasiyana dze evaporation. Tembiricha; inogona kuva sisitimu yechikamu chimwe chete kana sisitimu yezvikamu zviviri; inogona kuva sisitimu yechikamu chimwe chete kana sisitimu ye cascade, nezvimwewo. Mazhinji emacompressor akajairika masisitimu akafanana echikamu chimwe chete.
Zvikamu zvecompressor zvinoenderana nezvinodiwa nesystem yekutonhodza inochinja-chinja. Nekugadzirisa kutanga nekumira kwecompressor musystem yese, mamiriro e "bhiza guru nengoro diki" anodziviswa. Semuenzaniso, kana kudiwa kwesimba rekutonhodza kwakaderera munguva yechando, compressor inobatidzwa zvishoma, uye muzhizha, kudiwa kwesimba rekutonhodza kwakawanda, uye compressor inobatidzwa zvakanyanya. Kumanikidzwa kwekusveta kwecompressor kunochengetwa kwakafanana, izvo zvinovandudza kushanda kwesystem zvakanyanya. Kuedza kwakafanana kweyuniti imwe chete neyuniti yakafanana kwakaitwa pasystem imwe chete, uye system yeyuniti yakafanana inogona kuchengetedza simba ne18%.
Zvese zvinodzora macompressor, macondenser nema evaporator zvinogona kuiswa mubhokisi rekudzora remagetsi resystem, uye macomputer controllers anogona kushandiswa kuwedzera kushanda kwesystem. Chaizvoizvo, kushanda kwakakwana pasina munhu uye kushanda kure kunogona kuitwa.
2. Kutungamirirwa kwepombi uye kusarudzwa kwedhayamita yepombi
Kutungamira kwepaipi: MuFreon refrigeration system, oiri yekuzora compressor inotenderera musystem pamwe chete nerefrigerant, saka kuti ive nechokwadi chekuti oiri inodzoka zvakanaka musystem, pombi yemhepo inodzoka (pombi ine pressure yakaderera) inofanira kunge ine slope yakati Kuenda kucompressor, kazhinji ine slope ye0.5%.
Kusarudzwa kwedhayamita yepombi: Kana dhayamita yepombi yemhangura iri diki, kurasikirwa nekumanikidzwa kwerefrigerant mupombi yemvura (pombi yemhepo ine simba rakawanda) uye pombi yegesi inodzoserwa (pombi yemhepo ine simba rakaderera) zvichava zvakanyanya; Kana kukosha kwacho kwakanyanya, kunyangwe kurasikirwa kwekuramba mupombi kuchigona kuderedzwa, zvichakonzera kuwedzera kwemutengo wekutanga wekudyara, uye panguva imwe chete, zvichakonzerawo kusakwana kwekumhanya kwemafuta mupombi yemhepo inodzoserwa.
Nheyo yekusarudza dhayamita yepombi inokurudzirwa: kumhanya kwekuyerera kwemuchina wekuisa firiji mupombi yemvura i0.5-1.0m/s, isingapfuure 1.5m/s; mupombi yemhepo inodzoka, kumhanya kwekuyerera kwemuchina wekuisa firiji mupombi yakatwasuka i7-10m/s, kumhanya kwekuyerera kwemuchina wekuisa firiji mupombi iri kukwira i15~18m/s.
Dhizaini yerudzi rwebazi: Kune maheader emvura inobuda nemidziyo yemhepo inodzoka pachikamu chakaparara, uye kune matavi akawanda emvura inobuda pachikamu chakaparara, uye rimwe davi remhepo inodzoka rinoenderana nebazi rega rega remvura inobuda rinounganidzwa muPamusoro pemusoro wemhepo inodzoka, pombi yakadaro yesystem yekudziya inonzi rudzi rwebazi. Matavi maviri ega ega, kureva kuti, bazi remvura inobuda nebazi rayo remhepo rinodzoka, anogona kuva ne evaporator imwe chete (bazi 1) kana boka re evaporators (bazi n). Kana riri boka re evaporators, kazhinji boka re evaporators rinotanga uye rinomira panguva imwe chete.
Evaporator yakakwira kupfuura compressor:
Kana evaporator yakakwira kupfuura compressor, chero bedzi mutsetse wekudzosera uine mutserendende wakasiyana uye ukasarudza dhayamita yakakodzera yepombi, sisitimu inogona kuve nechokwadi chekuti mafuta anodzoka zvakanaka. Zvisinei, kana musiyano wekukwirira pakati pe evaporator ne compressor wakakura zvakanyanya, refrigerant yemvura iri mupombi yekupa mvura ichaburitsa steam yeflash isati yasvika panopinda throttling mechanism ye supercooling.
Evaporator yakaderera pane compressor:
Kana evaporator iri pasi pecompressor, refrigerant iri mupipe yemvura haizoburitse steam inopenya nekuda kwekusiyana kwehurefu pakati pe evaporator necompressor, asi pakugadzira pipe ye refrigeration system, kudzoka kwesystem kunofanirwa kutariswa zvizere. Dambudziko remafuta, panguva ino, oil return bend inofanira kugadzirwa uye kuiswa pachikamu chinokwira chebazi rega rega re return air.
