1. Tshooj ntawm Pangel Cov Chav Tub Yees
Chav tsev ua ke yog hais txog cov tsev tub yees uas sib xyaw ua ke ntau dua ob lub tshuab compressors rau hauv ib lub khib thiab ua haujlwm ntau evaporators. Cov compressors muaj ib qho kev nce evaporation siab thiab hws kom hws, thiab lub chav ntsuas lub zog tuaj yeem kho lub zog raws li lub zog. Nws tuaj yeem paub cov khaub ncaws hnav ntawm lub tshuab pa hluav taws xob, thiab cov tub yees ua haujlwm thaj chaw me me, thiab nws yooj yim kom paub txoj kev tswj hwm nruab nrab thiab chaw taws teeb tswj.
Tib cov teeb tsa ntawm cov koog tuaj yeem tsim tau ntawm tib hom kev compressors, lossis ntau hom kev compressors. Nws tuaj yeem tsim tau ntawm tib hom compressor (xws li piston tshuab), lossis nws tuaj yeem tsim ntawm ntau hom kev sib txuas (xws li piston tshuab + Screw Tshuab); Nws tuaj yeem thauj khoom kub ua si lossis ntau yam kev sib txawv ntawm kev sib txawv. Qhov kub; Nws tuaj yeem yog ib theem-theem theem lossis ob-theem theem; Nws tuaj yeem yog ib txoj kev siv ib-lub voj voog lossis cov txheej txheem ua haujlwm, thiab lwm yam. Feem ntau ntawm cov kev lag luam sib txuas yog tib lub voj voog uas sib txuas ntawm tib hom.
Parallel Compressor units zoo dua phim cov dynamic cua txias thauj ntawm cov tshuab nqus tub yees. Los ntawm kev kho qhov pib thiab nres ntawm lub compressor hauv tag nrho cov kab ke, qhov xwm txheej ntawm lub laub loj thiab me me "yog zam. Piv txwv li, thaum lub peev xwm txias uas xav tau tsawg nyob rau hauv lub caij ntuj no, lub caij ntuj sov tig mus rau tsawg, thiab lub zog cua txias xav tau loj, thiab lub tshuab compressor yog muab ntau dua. Lub siab siab ntawm chav ntsuas pa hluav taws xob yog khaws tas li, uas tau txhim kho cov kev ua tau zoo ntawm cov kab ke. Ib qho kev sib piv ntawm ib chav tsev thiab cov chav ua ntu zus tau ua tiav ntawm tib lub system, thiab cov chav ntsuas parallel tuaj yeem txuag lub zog los ntawm 18%.
Txhua qhov kev tswj hwm rau compressors, cov hws thiab evapators tuaj yeem siv nyob rau hauv lub system tswj hluav taws xob tswj tau kom ua haujlwm ntawm cov txheej txheem. Yeej, ua tiav kev ua haujlwm tsis muaj kev ua haujlwm thiab kev ua haujlwm ntawm thaj chaw deb tuaj yeem ua tiav.
2. Kab Kav Kev Taw Qhia thiab Cov Yeeb Nkab Hla
Cov Kev Taw Qhia Pipeline: Nyob rau hauv Frees Fr Freey tub yees, lub ntsuas cua rov qab los ua ke nrog cov kab txaij
Cov kab ntsig kab ntsig: yog tias txoj kab uas hla ntawm lub tub yees hauv lub thawv xa dej (cov raj xa hluav taws xob (roj siab rov qab siab) yuav dhau los ua loj heev; Yog tias tus nqi tseem loj dhau, txawm hais tias kev tsis kam nyob hauv cov raj dej yuav raug txo qis, nws yuav ua rau cov roj tsis txaus ntawm kev xa rov qab rau kev xa rov qab.
Lus qhia txog cov yeeb nkab kab uas xaiv lub hauv paus: Cov dej ntws tawm ntawm cov kua xa hluav taws xob yog 0.5-1.0m / s, tsis tshaj 1.5m / s; Nyob rau hauv kev xa rov qab cov raj xa dej, cov dej ntws tawm ntawm cov tub yees hauv kab rov tav yog 7-10M / s, cov dej ntws tawm hauv cov raj xa pa taws yog 15 ~ 18m / s.
Ceg Hom Tsim: Muaj cov kua los ua kua thiab rov qab siv cov hmoov av, thiab muaj ib qho khoom siv huab cua ua kom rov qab, thiab muaj ib qho khoom siv cua ua ke, thiab cov khoom siv ua kom rov qab los rau hauv cov kua dej Txhua khub ntawm cov ceg, uas yog, cov kua muab cov ceg thiab nws cov huab cua hloov pauv rov qab, tuaj yeem muaj ib pawg ntawm cov neeg sab nrauv (ceg n). Thaum nws yog ib pab pawg ntawm cov neeg ua dej ua ke, feem ntau yog pab pawg ntawm cov txiv ntoo pib thiab nres tib lub sijhawm.
Tus Evaporator yog siab dua lub compressor:
Yog hais tias tus Evaporator tau siab dua lub compressor, ntev li ntev li cov kab xa rov qab muaj qhov nqes ntawm txoj kab uas haum thiab xaiv cov roj rov qab kom du. Txawm li cas los xij, yog hais tias qhov siab txawv ntawm evaporator thiab lub tshuab pa taws xob loj heev, cov kua ua kua rau hauv cov dej ua kua ua ntej mus cuag lub tshuab throtling. ntawm supercooling.
Lub evaporator yog qis dua lub compressor:
If the evaporator is lower than the compressor, the refrigerant in the liquid supply pipeline will not produce flash steam due to the height difference between the evaporator and the compressor, but when designing the refrigeration system pipeline, the return of the system must be fully considered. Cov teeb meem roj, lub sijhawm no, cov roj rov qab khoov yuav tsum tsim thiab teeb tsa ntu nce toj ntawm txhua tus ceg rov qab.
