Yiziphi izinyathelo zokuphepha zokwakhiwa nokufakwa kwezinzwa zokushisa ze-NTC ezisetshenziswa kuma-air conditioner?

I. Ukucatshangelwa kokuklama nokukhetha

1. Ukuhambisana Kwebanga Lokushisa
   • Qinisekisa ukuthi izinga lokushisa lokusebenza le-NTC limboza indawo yesistimu ye-AC (isb, -20°C kuya ku-80°C) ukuze ugweme ukukhukhuleka kokusebenza noma ukulimala ngenxa yokweqa imikhawulo.
2. Ukunemba kanye Nokulungiswa
   • Khetha izinzwa ezinemba okuphezulu (isb, ±0.5°C noma okungcono) ukuze uthuthukise ukuzwela kokulawula izinga lokushisa. Ukulungiswa kufanele kufane nezidingo zesistimu (isb, 0.1°C).
3. Ukuthuthukisa Isikhathi Sokuphendula
   • Beka kuqala izinzwa ezinezikhathi ezishisayo eziphansi (isb, τ ≤10 amasekhondi) ukuze unike amandla impendulo esheshayo futhi uvimbele ukuhamba ngebhayisikili komminyanisi.
4. Ukupakisha Nokuqina
   • Sebenzisa i-epoxy resin noma i-glass encapsulation ukuze umelane nomswakama, ukujiya, nokugqwala kwamakhemikhali. Izinzwa zeyunithi yangaphandle kufanele zihlangabezane nesilinganiso se-IP67.

II. Indawo yokufaka kanye neMechanical Design

1. Ukukhetha Indawo
   • Ukuqapha kwe-Evaporator/Condenser:Namathisela ngqo endaweni yamakhoyili, ugweme ukugeleza komoya okuqondile (isb., >5 cm ukusuka ezintubeni).
   • Buyisela Izinga Lokushisa Lomoya:Faka phakathi nendawo yamapayipi abuyayo, kude nemithombo yokushisisa/yokupholisa.
2. I-Thermal Coupling
   • Vikela izinzwa ngamafutha ashisayo noma izinsimbi zensimbi ukuze unciphise ukumelana nokushisa phakathi kwenzwa nendawo eqondiwe.
3. Ukunciphisa Ukuphazamiseka Kokugeleza Komoya
   • Engeza izihlangu zokugeleza komoya noma sebenzisa ama-probe anezivikelo ukuze unciphise imiphumela yesivinini somoya (okubalulekile kumasistimu okupholisa umoya).

III. Izinkombandlela Zokuklama Kwesekethe

1. Amapharamitha we-Voltage Divider
   • Fanisa izinqamuleli ezidonsela phezulu nokumelana okulinganiselwe kwe-NTC (isb, 10kΩ ku-25°C) ukuze kuqinisekiswe ukuthi i-voltage yokufaka ye-ADC iwela phakathi kwebanga elisebenzayo (isb, 1V–3V).
2. Ukwenziwa komugqa
   • Sebenzisa isibalo se-Steinhart-Hart noma amathebula okubheka kancane ukuze unxephezele ngokungaqondile futhi uthuthukise ukunemba.
3. I-Noise Immunity
   • Sebenzisa izintambo ezisontekile/ezivikelekile, umzila osuka emithonjeni yomsindo ophezulu (isb., ama-compressor), futhi wengeze izihlungi ze-RC zephasi eliphansi (isb, 10kΩ + 0.1μF).

   
IV. Ukuzivumelanisa Nemvelo

1. Ukuvikelwa Komswakama
   • Vala izinzwa zangaphandle ngezinhlanganisela zokubumba futhi usebenzise izixhumi ezingangeni manzi (isb., amapulagi endiza ye-M12).
2. Ukumelana Nokudlidliza
   • Vikela izinzwa ngezikhwezi eziguquguqukayo (isb., amaphedi e-silicone) ukuze uvimbele izinkinga zokuxhumana kusukela ekudlidlizeni kwe-compressor.
3. Ukuvimbela Uthuli
   • Hlanza njalo izinzwa noma sebenzisa amakhava okuvikela akhiphekayo (isb., anezikhala zensimbi).

V. Ukulinganiswa Nokugcinwa

1. I-Multi-Point Calibration
   • Linganisa emazingeni okushisa abalulekile (isb., 0°C ingxube yamanzi eqhwa, 25°C igumbi elishisayo, 50°C okugeza kawoyela) ukuze ubhekane nokuhluka kwenqwaba.
2. Ukuhlola Ukuzinza Kwesikhathi Eside
   • Yenza ukulinganisa kwenkambu njalo eminyakeni emi-2 ukuze uqinisekise ukukhukhuleka (isb, ukukhukhuleka konyaka ≤0.1°C).
3. I-Fault Diagnostics
   • Sebenzisa ukutholwa komjikelezo ovulekile/omfishane kanye nezixwayiso zokucupha (isb, ikhodi yephutha ye-E1) mayelana nokungajwayelekile.

VI. Ukuphepha Nokuhambisana

1. Izitifiketi
   • Qinisekisa ukuthobelana namazinga e-UL, CE, kanye ne-RoHS ngokuphepha nezidingo zemvelo.
2. Ukuhlolwa kwe-Insulation
   • Qinisekisa ukuthi ikhebula likwazi ukumelana no-1500V AC iminithi elingu-1 ukuze uvimbele izingozi zokuwohloka.

Izinkinga Ezivamile Nezixazululo

• Inkinga:Ukusabela kwenzwa ebambezelekile okubangela ukujikeleza kwe-compressor.
  Isixazululo:Sebenzisa ama-probes amancane (okuphansi τ) noma ulungiselele ama-algorithms okulawula i-PID.
• Inkinga:Ukwehluleka ukuthintana okubangelwa ukujiya.
  Isixazululo:Beka kabusha izinzwa kude nezindawo zokufingqa noma sebenzisa okokunamathela kwe-hydrophobic.

Ngokubhekana nalezi zici, izinzwa ze-NTC zingaqinisekisa ukusebenza okuthembekile ezinhlelweni ze-AC, ukuthuthukisa ukusebenza kahle kwamandla (EER) nokwelula isikhathi sokuphila kwemishini.
