Ib chav tsev txias cia ua ke yog hais txog chav tub yees uas muaj ob lossis ntau dua compressors uas sib koom ua ke ntawm cov tub yees circuits nyob rau hauv parallel.Nyob ntawm lub tub yeesqhov kub thiab txias muaj peev xwm thiab kev sib xyaw ua ke ntawm cov condensers, cov chav nyob sib txuas tuaj yeem muaj ntau hom.
Tib chav tsev tuaj yeem tsim cov compressors ntawm tib hom lossis ntau hom compressors.Nws tuaj yeem tsim los ntawm tib hom compressor (xws li piston tshuab),los yognws tuaj yeem tsim los ntawm ntau hom compressor (xws li piston tshuab + ntsia hlau tshuab);Nws tuaj yeem thauj tau ib qho evaporation kub lossis ntau qhov sib txawv evaporationkub;nws tuaj yeem yog ib theem system lossis ob-theem system;Nws tuaj yeem yog ib lub voj voog ib zaug lossis ib qho cascade, thiab lwm yam. Cov compressors feem ntau yog ib lub voj voogparallel systems ntawm tib hom.
Rau me me thiab nruab nrab-qhov txias cia, lub tshuab scroll me me dhau lawm, lub tshuab ntsia hlau yog kim heev rau kev sib txuas ua ke, cov qauv piston kuj yog nruab nrab, thiabtustus nqi yog siab tshaj.

Dab tsi yog qhov zoo ntawm parallel units?
1) Ib qho txiaj ntsig zoo tshaj plaws ntawm cov chav sib txuas yog kev ntseeg siab.Thaum lub compressor hauv chav ua tsis tiav, lwm cov compressors tseem tuaj yeem ua haujlwm li qub.Yog sawv daws-ib leeg tsis ua haujlwm, txawm tias muaj kev tiv thaiv me me yuav tiv thaiv nws los ntawm kev kaw.Qhov chaw txias txias yog nyob rau hauv lub cev tuag tes tuag taw, ua rau muaj kev hem thawj rau qhov zoo ntawm cov khoom khaws cia hauvkhaws cia.Tsis muaj lwm txoj kev mus tsuas yog tos kev kho.
2) Lwm qhov txiaj ntsig zoo ntawm cov chav sib txuas yog kev ua haujlwm siab thiab cov nqi khiav haujlwm qis.Raws li peb txhua tus paub, lub tub yees system yog nruab nrog compressors raws li lubyam phem tshaj plaws.Qhov tseeb, lub tub yees system khiav ntawm ib nrab-load cov xwm txheej feem ntau ntawm lub sijhawm.Nyob rau hauv cov xwm txheej zoo li no, tus nqi COP ntawm chav nyob sib npaug tuaj yeem ua tiav raws sijhawmnrog rau tag nrho-load mob.Nyob rau tib lub sijhawm, tus nqi COP ntawm ib chav tsev nyob rau lub sijhawm no yuav raug txo los ntawm ntau dua ib nrab.Nyob rau hauv ib qho kev sib piv zoo, ib chav nyob sib npaug tuaj yeem txuag tau30-50% hluav taws xob ntau dua li ib chav tsev.
3) Kev ua haujlwm siab thiab kev txuag hluav taws xob, kev tswj lub peev xwm tuaj yeem ua tiav hauv theem, los ntawm kev sib xyaw ntawm ntau lub tshuab compressors, ntau theem kev hloov kho lub zog tuaj yeem ua tau.muab, thiab qhov tso zis chiller ntawm chav tsev tuaj yeem phim qhov kev thov tiag tiag.Ntau lub compressors tuaj yeem ua ntau qhov sib txawv kom ua tau raws li qhov tseeb ntawm qhov hnyav dua,yog li paub txog qhov zoo tshaj plaws lub zog hloov kho rau kev hloov pauv, txhim kho kev ua haujlwm thiab txuag hluav taws xob.
4) Parallel units muaj kev tiv thaiv ntau dua, feem ntau nrog tag nrho cov txheej txheem kev tiv thaiv kev nyab xeeb nrog rau theem poob, rov qab ua ntu zus, overvoltage, undervoltage, roj.siab, siab voltage, tsis tshua muaj voltage, hluav taws xob qis qis, thiab hluav taws xob lub cev muaj zog overload.
5) Muab ntau qhov kev tshoov siab ceg tswj.Raws li kev xav tau, ib chav tsev tuaj yeem muab ntau yam evaporating kub, zoo siv lub peev xwm txias ntawm txhua qhov evaporating.qhov kub thiab txias, kom lub kaw lus tuaj yeem khiav hauv qhov kev txuag hluav taws xob tshaj plaws.
