Kub sensors yog cov khoom tseem ceeb hauv cov twj tso kua mis kub. Lawv ua raws li lub system "sensory organs," lub luag haujlwm rau kev soj ntsuam qhov kub thiab txias ntawm qhov chaw tseem ceeb. Cov ntaub ntawv no tau rov qab mus rau pawg tswj hwm ("lub hlwb"), ua kom lub kaw lus txiav txim siab thiab hloov kho. Qhov no ua kom muaj kev ua haujlwm zoo, nyab xeeb, thiab xis nyob.
Nov yog cov haujlwm tseem ceeb ntawm cov ntsuas kub ntsuas hauv cov twj tso cua sov:
1. Saib xyuas Evaporator thiab Condenser Kub:
- Evaporator (Tshwj xeeb sab hauv tsev hauv cua sov hom):Saib xyuas qhov kub thiab txias thaum lub tub yees absorbs cua sov los ntawm huab cua sab hauv. Qhov no pab:
- Tiv thaiv Frost Buildup:Thaum cov evaporator kub poob qis dhau (ze los yog qis dua khov), cov dej noo hauv cov huab cua tuaj yeem khov rau hauv lub kauj (teev), ua rau muaj kev cuam tshuam loj heev rau kev hloov hluav taws xob. Sensors pom qhov kub tsis tshua muaj tshwm simdefrost voj voog.
- Optimize Efficiency:Xyuas kom lub evaporator kub nyob twj ywm nyob rau hauv qhov zoo tshaj plaws ntau yam kom ua kom cov cua sov nqus efficiency ntawm qhov chaw (cua, dej, av).
- Ntsuam xyuas lub xeev tub yees:Pab txiav txim siab kom raug nqi tub yees thiab ua kom tiav evaporation, feem ntau ua ke nrog lub siab sensors.
- Condenser (Sab nraum zoov kauj hauv cua sov hom):Saib xyuas qhov kub thiab txias thaum lub tub yees tso cua sov rau sab nraum zoov. Qhov no pab:
- Tiv thaiv overheating:Xyuas kom lub condensing kub nyob twj ywm nyob rau hauv kev nyab xeeb txwv. Kev kub siab condensing ntau dhau txo kev ua haujlwm thiab tuaj yeem ua rau lub compressor puas.
- Optimize Thaum tshav kub kub Rejection:Tswj lub condenser kiv cua ceev kom sib npaug zog efficiency nrog kub rejection peev.
- Ntsuam xyuas lub xeev tub yees:Kuj tseem pab ntsuas kev ua haujlwm ntawm lub cev thiab cov tub yees qib.
2. Saib xyuas qhov kub thiab txias nyob sab hauv tsev:
- Indoor Temperature Sensor:Core kom ua tiavtswj kev nplij siab.
- Setpoint Control:Ncaj nraim ntsuas qhov ntsuas kub hauv tsev thiab muab piv rau tus neeg siv lub hom phiaj kub. Lub Rooj Tswjhwm Saib Xyuas siv qhov no los txiav txim siab thaum twg pib, nres, lossis hloov kho lub twj tso kua mis lub peev xwm (hauv inverter qauv).
- Tiv thaiv overheating / Overcooling:Ua raws li kev ruaj ntseg mechanism los tiv thaiv qhov txawv txav ntawm qhov kub thiab txias.
- Sab nraum zoov Ambient Kub Sensor:Saib xyuas huab cua sab nraum zoov, uas yog qhov tseem ceeb rau kev ua haujlwm ntawm lub cev.
- Hloov hom:Nyob rau hauv huab cua txias heev, thaum lub peev xwm cua sov ntawm lub tshuab cua kub lub twj tso kua mis poob qis heev, qhov ntsuas kub tsis tshua muaj peev xwm ua rau muaj kev ua haujlwm ntawmauxiliary electric heaterslos yog hloov cov tswv yim khiav hauj lwm hauv qee lub tshuab.
- Defrost Trigger / Termination:Sab nraum zoov kub yog qhov tseem ceeb (feem ntau ua ke nrog evaporator kub) hauv kev txiav txim siab defrost zaus thiab sijhawm.
- Kev ua tau zoo optimization:Lub kaw lus tuaj yeem kho qhov kev ua haujlwm tsis zoo (piv txwv li, compressor ceev, kiv cua ceev) raws li qhov kub ntawm sab nraum zoov kom ua tau zoo.
3. Kev Tiv Thaiv thiab Saib Xyuas Compressor:
- Compressor Discharge Kub Sensor:Ncaj nraim saib xyuas qhov kub thiab txias ntawm high-pressure, high-temperature refrigerant gas tawm hauv compressor. Qhov no yog ibKev ntsuas kev nyab xeeb tseem ceeb:
- Tiv thaiv overheating puas:Cov cua kub ntau dhau tuaj yeem ua rau cov compressor lubrication thiab cov khoom siv tshuab ua kom puas. Lub sensor txib kom kaw lub compressor tam sim yog tias kuaj pom qhov kub dhau.
- System Diagnostics:Qhov ntsuas kub tsis zoo yog qhov ntsuas tseem ceeb rau kev kuaj xyuas cov teeb meem hauv lub cev (piv txwv li, cov khoom siv tub yees qis, txhaws, overload).
- Compressor Plhaub Kub Sensor:Saib xyuas qhov kub ntawm lub compressor vaj tse, muab ib txheej ntxiv ntawm kev tiv thaiv overheating.
4. Kev Saib Xyuas Cov Cuab Yeej Kub Kub:
- Suction Line (Return Gas) Kub Sensor:Saib xyuas qhov ntsuas kub ntawm cov roj tub yees nkag mus rau hauv compressor.
- Tiv thaiv kua Slugging:Qhov ntsuas kub qis qis heev (qhia tau tias muaj peev xwm ua tau cov kua refrigerant rov qab mus rau lub compressor) tuaj yeem ua rau lub compressor puas. Lub sensor tuaj yeem ua rau muaj kev tiv thaiv.
- System Efficiency & Diagnostics:Suction kab kub yog qhov tseem ceeb rau kev ntsuas kev ua haujlwm (xws li, kev tswj hwm superheat, refrigerant leaks, tsis raug nqi).
- Liquid Line Temperature Sensor:Qee lub sij hawm siv los saib xyuas qhov kub ntawm cov kua refrigerant tawm hauv lub condenser, pab hauv kev ntsuam xyuas subcooling lossis system ua haujlwm.
5. Tswj lub Defrost Cycle:
- Raws li tau hais, lubevaporator kub sensorthiabsab nraum zoov ambient kub sensoryog cov tswv yim tseem ceeb rau kev pib thiab xaus lub voj voog defrost. Tus maub los siv cov logic preset (piv txwv li, raws sijhawm, qhov kub thiab txias sib txawv) los txiav txim siab thaum twg defrost xav tau (feem ntau yog thaum lub evaporator kub qis dhau rau lub sijhawm ruaj khov) thiab thaum nws ua tiav (thaum lub evaporator lossis condenser kub nce rov qab mus rau tus nqi teev).
6. Tswj Cov Khoom Pab Txhawb:
- Auxiliary rhaub Control:Thaum lubsab hauv tsev kub sensorkuaj pom cua sov qeeb lossis tsis muaj peev xwm ncav cuag qhov chaw teeb tsa, thiabSab nraum zoov kub sensorqhia tias qhov kub thiab txias ambient qis heev, lub rooj tsavxwm tswj activates auxiliary electric heaters (heating elements) ntxiv rau cov cua sov.
- Dej Tank Temperature (rau Cua-rau-Dej Twj Kub Kub):Nyob rau hauv cov twj tso kua mis kub siab rau cov dej cua sov, qhov ntsuas kub hauv lub tank dej yog qhov tseem ceeb los tswj lub hom phiaj cua sov.
Hauv cov ntsiab lus, lub luag haujlwm ntawm qhov ntsuas kub ntsuas hauv cov twj tso cua sov tuaj yeem raug cais raws li:
- Core Control:Enabling meej chav ntsuas kub thiab tswj kev nplij siab.
- Efficiency Optimization:Ua kom lub cev ua haujlwm tau zoo raws li qhov ua tau raws li ntau yam xwm txheej, txuag lub zog.
- Kev Tiv Thaiv Kev Nyab Xeeb:Tiv thaiv kev puas tsuaj tseem ceeb (compressor overheating, kua slugging, system overpressure / underpressure - feem ntau ua ke nrog lub siab sensors).
- Automated ua haujlwm:Intelligently tswj lub voj voog defrost, auxiliary heater activation / deactivation, kiv cua ceev modulation, thiab lwm yam.
- Fault Diagnosis:Muab cov ntaub ntawv ntsuas kub tseem ceeb rau cov kws tshaj lij rau kev kuaj xyuas cov teeb meem hauv lub cev (xws li, cov dej xau ntawm lub tub yees, thaiv, cov khoom tsis ua haujlwm).
Yog tias tsis muaj cov ntsuas kub no tau muab tso rau ntawm cov ntsiab lus tseem ceeb thoob plaws hauv lub cev, lub twj tso kua mis kub tsis tuaj yeem ua tiav nws cov txiaj ntsig, ntse, txhim khu kev qha, thiab kev ua haujlwm nyab xeeb. Lawv yog cov khoom tseem ceeb ntawm cov twj siv hluav taws xob niaj hnub no.
