Ndi njira ziti zodzitetezera pakupanga ndi kuyika kwa masensa a kutentha kwa NTC omwe amagwiritsidwa ntchito muzoziziritsa mpweya?

I. Mapangidwe ndi Zosankha

1. Kutentha Kwamitundu Yosiyanasiyana
   • Onetsetsani kuti kutentha kwa ntchito ya NTC kumakhudza chilengedwe cha AC system (monga -20°C mpaka 80°C) kupeŵa kusasunthika kapena kuwonongeka kopitilira malire.
2. Kulondola ndi Kutsimikiza
   • Sankhani masensa olondola kwambiri (mwachitsanzo, ± 0.5°C kapena kupitilira apo) kuti muwonjezere chidwi chowongolera kutentha. Kusamvana kuyenera kugwirizana ndi zofunikira za dongosolo (mwachitsanzo, 0.1 ° C).
3. Kukonzekera Kwanthawi Yamayankho
   • Ikani patsogolo masensa okhala ndi nthawi yocheperako yotentha (mwachitsanzo, τ ≤10 masekondi) kuti athe kuyankha mwachangu ndikupewa kupalasa njinga ya kompresa.
4. Kupaka ndi Kukhalitsa
   • Gwiritsani ntchito epoxy resin kapena galasi encapsulation kuti mupewe chinyezi, condensation, ndi dzimbiri. Masensa akunja akuyenera kukwaniritsa IP67.

II. Kuyika Position ndi Mechanical Design

1. Kusankha Malo
   • Evaporator/Condenser Monitoring:Gwirizanitsani molunjika pamalo opindika, kupewa kutuluka kwa mpweya wolunjika (mwachitsanzo,> 5 cm kuchokera ku mpweya).
   • Kubwerera Kutentha kwa Air:Ikani pakati pa mayendedwe obwerera, kutali ndi zotenthetsera / zoziziritsa.
2. Thermal Coupling
   • Tetezani masensa okhala ndi mafuta otenthetsera kapena zitsulo zachitsulo kuti muchepetse kukana kwamafuta pakati pa sensa ndi malo omwe mukufuna.
3. Kuchepetsa Kusokoneza kwa Airflow
   • Onjezani zishango za kayendedwe ka mpweya kapena gwiritsani ntchito ma probe okhala ndi zotchinga kuti muchepetse kuthamanga kwa mphepo (yofunikira pamakina oziziritsa mpweya).

III. Njira Zopangira Magawo

1. Magawo a Voltage Divider
   • Fananizani zopinga zokokera m'mwamba ndi kukana mwadzina kwa NTC (mwachitsanzo, 10kΩ pa 25°C) kuwonetsetsa kuti magetsi a ADC akugwera mkati mwaothandiza (mwachitsanzo, 1V–3V).
2. Linearization
   • Ikani ma equation a Steinhart-Hart kapena matebulo oyang'ana pang'onopang'ono kuti mubwezere kusagwirizana ndikuwongolera kulondola.
3. Phokoso Chitetezo
   • Gwiritsani ntchito zingwe zopotoka/zotchinga, njira yotalikirana ndi magwero aphokoso kwambiri (mwachitsanzo, kompresa), ndi kuwonjezera zosefera za RC zotsika pang'ono (mwachitsanzo, 10kΩ + 0.1μF).

   
IV. Kusinthasintha Kwachilengedwe

1. Chitetezo cha Chinyezi
   • Tsekani masensa akunja ndi zinthu zopangira miphika ndikugwiritsa ntchito zolumikizira zopanda madzi (monga mapulagi a M12 aviation).
2. Kukaniza Kugwedezeka
   • Tetezani masensa okhala ndi zokwera zosinthika (monga ma silikoni pads) kuti mupewe kukhudzana ndi kugwedezeka kwa kompresa.
3. Kupewa Fumbi
   • Nthawi zonse muziyeretsa masensa kapena gwiritsani ntchito zovundikira zochotseka (monga zitsulo mauna).

V. Kulinganiza ndi Kusamalira

1. Multi-Point Calibration
   • Yang'anirani pa kutentha kwakukulu (mwachitsanzo, 0 ° C osakaniza ndi madzi oundana, 25 ° C chipinda chotenthetsera, 50 ° C osamba mafuta) kuti muthetse kusiyana kwa magulu.
2. Kuyang'ana Kukhazikika Kwanthawi Yaitali
   • Yendetsani kuwongolera zaka 2 zilizonse kuti mutsimikizire ngati mukuyendetsa (mwachitsanzo, kuyenda kwapachaka ≤0.1°C).
3. Fault Diagnostics
   • Yambitsani kuzindikira kotseguka/kwachidule ndi zidziwitso zoyambitsa (mwachitsanzo, E1 code code) pazovuta.

VI. Chitetezo ndi Kutsata

1. Zitsimikizo
   • Onetsetsani kuti mukutsatira miyezo ya UL, CE, ndi RoHS pachitetezo ndi zofunikira zachilengedwe.
2. Kuyesa kwa Insulation
   • Tsimikizirani kutchinjiriza kwa chingwe kumapirira 1500V AC kwa mphindi imodzi kuti mupewe kuwonongeka.

Mavuto Wamba ndi Mayankho

• Nkhani:Kuchedwetsa kuyankha kwa sensa komwe kumayambitsa kuyendetsa njinga ya kompresa.
  Yankho:Gwiritsani ntchito ma probe ang'onoang'ono (otsika τ) kapena konzani ma algorithms owongolera a PID.
• Nkhani:Kulephera kukhudzana ndi condensation.
  Yankho:Ikani masensa kutali ndi madera a condensation kapena gwiritsani zokutira za hydrophobic.

Pothana ndi izi, masensa a NTC amatha kuwonetsetsa kuti akugwira ntchito modalirika pamakina a AC, kukonza mphamvu zamagetsi (EER) ndikukulitsa moyo wa zida.
