1. Supercooling / subcooling degree
Supercooling yog hais txog kev ua kom txias ntxiv rau cov tub yees uas tau condensed rau hauv cov kua saturated kom nws qhov kub thiab txias qis dua qhov kub ntawm lub xeev saturated nyob rau hauv lub siab. Cov txheej txheem no tuaj yeem pom tau tias yog ib kauj ruam ua kom txias dua li qhov ntsuas kub ib txwm.
Subcooling yog ib qho kev ntsuas ntawm cov degree ntawm supercooling, tshwj xeeb yog txhais raws li qhov sib txawv ntawm qhov tseeb kub ntawm cov kua tom qab supercooling thiab saturation kub ntawm cov kua nyob rau hauv tib lub siab. Hauv lwm lo lus, yog tias cov kua dej txias dua qhov kub ntawm qhov uas nws yuav tsum tau pib ua kom muaj zog (lossis nyob twj ywm hauv cov kua saturated) ntawm nws lub siab tam sim no, ces qhov sib txawv ntawm qhov kub qis no yog hu ua subcooling.
Vim li cas thiaj xav tau subcooling
Txhim kho kev ua tau zoo: Supercooling tuaj yeem txo cov roj flash (uas yog, ib feem ntawm cov kua evaporates rau hauv cov pa) uas ua los ntawm kev poob siab thaum lub refrigerant throttling (xws li los ntawm lub expansion valve lossis capillary raj). Cov roj teeb flash no tuav ntau lub ntim tab sis tsis tuaj yeem ua kom muaj peev xwm ua kom txias, yog li txo qhov ua tau zoo ntawm lub tub yees. Subcooling tuaj yeem txo qhov feem pua ntawm cov roj flash, yog li chav tsev ntawm cov tub yees muaj peev xwm ua kom txias dua.
Optimize system stability: Los ntawm kev tswj cov qib ntawm subcooling, kev khiav hauj lwm ntawm lub tub yees system yuav stabilized, kub hloov pauv, thiab tag nrho cov kev ntseeg tau thiab tswj tau raug txhim kho.
Lub ntsiab lus ntawm subcooling
Txhim kho kev ua kom txias txias: Los ntawm kev txo qis cov theem tsis tsim nyog hloov pauv, lub kaw lus tuaj yeem ua tiav qhov txias txias nrog kev siv hluav taws xob tsawg.
Txhim kho lub neej ntawm cov cuab yeej siv: Tsis txhob muaj kev puas tsuaj rau compressor vim cov kua hammering, txo cov zaus txij nkawm, thiab txuas lub neej kev pab cuam ntawm tag nrho cov kab ke.
Txhim khu kev ua haujlwm zoo: Kev ruaj khov subcooling pab lub kaw lus teb sai rau kev hloov pauv, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas yuav tsum tau ua kom txias sai.
Kev txuag hluav taws xob thiab txo qis emission: Txo kev siv hluav taws xob thaum ua tau raws li qhov xav tau ntawm lub tub yees, ua raws li niaj hnub kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig.
2. Overheating / overheating degree
Superheating txhais tau hais tias nyob rau hauv tej yam kev mob siab, qhov kub ntawm cov tub yees chav txias tshaj qhov kub ntawm saturated chav nyob rau hauv lub siab ntawd. Lub tshuab tub yees nyob rau lub sijhawm no yog hu ua superheated chav, thiab superheating yog ib txwm muaj nyob rau hauv cov theem ntawm lub compressor nyob rau hauv lub tub yees system.
Lub degree ntawm superheat yog ib qho kev ntsuas ntawm lub degree ntawm superheat, tshwj xeeb yog txhais raws li qhov sib txawv ntawm qhov kub ntawm superheated chav thiab qhov kub ntawm saturated chav ntawm tib lub siab. Uas yog hais tias, lub degree ntawm superheat yog qhov kub ntawm qhov chaw ntawm lub superheated chav uas nws qhov tseeb kub yog siab tshaj nws saturation kub.
Vim li cas thiaj xav tau superheat?
Tsis txhob ua kua rauj: Hauv lub tub yees, qhov tsim nyog ntawm superheat tuaj yeem ua kom lub zog nqus mus rau hauv lub compressor kom qhuav, tiv thaiv kom tsis txhob ntub dej los yog kua refrigerant los ntawm kev nkag mus rau hauv compressor, yog li tiv thaiv kua rauj. Cov kua slugging tuaj yeem ua rau compressor puas, txo cov kev ua haujlwm ntawm lub cev, thiab txawm tias cov khoom puas tsuaj.
Kev tswj hwm kev tswj hwm: Hauv cov tshuab tub yees siv cov khoom siv nthuav dav, superheat yog siv los ua cov lus qhia tseem ceeb los tswj qhov qhib ntawm lub thermal expansion valve. Los ntawm kev tswj cov qib ntawm superheat, qhov ntws ntawm cov tub yees tuaj yeem hloov kho kom raug, yog li tswj cov cua txias ntawm cov evaporator thiab tswj kev ua haujlwm ruaj khov ntawm lub cev.
Txhim kho kev ua haujlwm zoo: Tsim nyog superheat tuaj yeem pab txo qhov xwm txheej uas cov tub yees tsis tau evaporated tag nrho ntawm cov evaporator thiab nqus mus rau hauv compressor. Qhov no tuaj yeem ua rau kom muaj peev xwm ua kom txias rau ib chav tsev ntawm cov tub yees, yog li kev txhim kho tag nrho cov tub yees efficiency ntawm lub system.
Lub ntsiab lus ntawm superheat
Ua kom muaj kev nyab xeeb ntawm compressor: Los ntawm kev zam cov kua slugging, superheat tiv thaiv lub compressor los ntawm kev puas tsuaj thiab txuas ntxiv lub neej ntawm cov khoom siv.
Txhim kho qhov kev ruaj ntseg: Los ntawm kev tswj xyuas meej, superheat pab tswj kev ruaj ntseg thiab kev ntseeg siab ntawm kev ua haujlwm ntawm lub cev, kom ntseeg tau qhov txuas ntxiv thiab sib xws ntawm cov cua txias.
Optimize zog efficiency: Tsim nyog tswj ntawm superheat yuav zam tsis tsim nyog pov tseg ntawm lub zog thiab txhim kho lub zog efficiency piv thaum ua kom cov cua txias.
Kev kuaj xyuas yooj yim thiab kev saib xyuas: Kev saib xyuas ntawm superheat kuj yog ib qho tseem ceeb rau kev txiav txim siab seb lub tub yees ua haujlwm li cas. Qhov txawv txav superheat tuaj yeem yog qhov qhia txog kev ua haujlwm tsis ua haujlwm, uas pab txhawm rau txheeb xyuas cov teeb meem hauv lub sijhawm thiab ua haujlwm tu.
