Kedu ihe kpachara anya maka imewe na ntinye nke ihe mmetụta okpomọkụ NTC ejiri na ikuku ikuku?

I. Atụmatụ na Nhọrọ

1. Ndakọrịta oke okpomọkụ
   • Gbaa mbọ hụ na oke okpomọkụ nke NTC na-arụ ọrụ na-ekpuchi gburugburu sistemụ AC (dịka -20°C ruo 80°C) iji zere ịkpafu arụmọrụ ma ọ bụ mmebi site na oke oke.
2. Izi ezi na Mkpebi
   • Họrọ ihe mmetụta dị elu (dịka ọmụmaatụ, ± 0.5°C ma ọ bụ ka mma) iji kwalite mmetụta njikwa okpomọkụ. Mkpebi kwesịrị ikwekọ n'ihe sistemu chọrọ (dịka 0.1°C).
3. Nkwalite oge nzaghachi
   • Wepụta ihe mmetụta nwere obere oge okpomọkụ dị ala (dịka ọmụmaatụ, τ ≤10 sekọnd) iji mee ka nzaghachi ngwa ngwa wee gbochie ịgba ígwè compressor.
4. Nkwakọ ngwaahịa na ịdịte aka
   • Jiri epoxy resin ma ọ bụ mkpuchi enyo mee ihe iji guzogide iru mmiri, ikuku, na corrosion kemịkalụ. Ihe mmetụta n'èzí kwesịrị iru ọkwa IP67.

II. Ọkwa nwụnye na Mechanical Design

1. Nhọrọ ebe
   • Nyochaa evaporator/condenser:Jikọọ ozugbo n'elu eriri igwe, na-ezere ikuku ikuku ozugbo (dịka,> 5 cm site na ikuku ikuku).
   • Weghachite okpomọkụ:Wụnye n'etiti ọwa nlọghachi, na-esighi na isi mmalite kpo oku/ajụjụ oyi.
2. Njikọ okpomọkụ
   • Chekwaa sensọ nwere griiz ọkụ ma ọ bụ mgbachi igwe iji belata nguzogide okpomọkụ n'etiti ihe mmetụta na elu ebumnuche.
3. Mbelata nnyonye anya ikuku
   • Tinye ihe mkpuchi ikuku ma ọ bụ jiri nyocha nwere mkpuchi iji belata mmetụta ọsọ ikuku (dị oke mkpa maka sistemu jụrụ oyi).

III. Ntuziaka nhazi okirikiri

1. Paramita nkesa voltaji
   • Dakọtara resistors na-adọta elu na nguzogide NTC (dịka, 10kΩ na 25°C) iji hụ na voltaji ntinye ADC dara n'ime oke dị irè (dịka, 1V–3V).
2. Linearization
   • Tinye nhazi Steinhart-Hart ma ọ bụ tebụl nleba anya nkenke iji kwụọ ụgwọ maka adịghị adịte aka wee kwalite izi ezi.
3. Mgbochi mkpọtụ
   • Jiri eriri gbagọrọ agbagọ/gbagọrọ agbagọ, pụọ na isi mmalite mkpọtụ dị elu (dịka ọmụmaatụ, compressors), tinyekwa ihe nzacha RC dị ala (dịka ọmụmaatụ, 10kΩ + 0.1μF).

   
IV. Ndakọrịta gburugburu

1. Nchekwa mmiri mmiri
   • Mechie ihe mmetụta n'èzí na ogige ite ma jiri njikọ mmiri na-adịghị (dịka ọmụmaatụ, M12 plọg ụgbọ elu).
2. Nguzogide ịma jijiji
   • Chekwaa sensọ nwere mgbago na-agbanwe agbanwe (dịka ọmụmaatụ, paịlị silicone) iji gbochie okwu kọntaktị site na ịma jijiji compressor.
3. Mgbochi uzuzu
   • Na-asachapụ ihe mmetụta mgbe niile ma ọ bụ jiri mkpuchi mkpuchi mbughari (dịka ntupu igwe).

V. Nhazi na mmezi

1. Multi-point calibration
   • Hazie na isi okpomọkụ (dịka ọmụmaatụ, 0°C ngwakọta mmiri ice, 25°C thermal chamber, 50°C mmanụ bath) iji lebara ọdịiche ogbe.
2. Nlele nkwụsi ike ogologo oge
   • Mee nhazi ọkwa mpaghara kwa afọ 2 iji nyochaa mkpagharị (dịka ọmụmaatụ, mbanye kwa afọ ≤0.1°C).
3. Nchọpụta mmejọ
   • Mepụta nchọpụta oghere/mkpụmkpụ ma kpalite ọkwa (dịka, koodu njehie E1) maka adịghị mma.

VI. Nchekwa na nnabata

1. Asambodo
   • Gbaa mbọ hụ na nnabata na ụkpụrụ UL, CE na RoHS maka nchekwa na ihe achọrọ gburugburu.
2. Nnwale mkpuchi mkpuchi
   • Nyochaa mkpuchi USB na-eguzogide 1500V AC maka nkeji 1 iji gbochie ihe egwu ndakpọ.

Okwu na ngwọta nkịtị

• Okwu:Nzaghachi ihe mmetụta na-egbu oge na-akpata ịgba ígwè compressor.
  Ngwọta:Jiri obere nyocha (obere τ) ma ọ bụ bulite algọridim njikwa PID.
• Okwu:ọdịda kọntaktị kpatara condensation.
  Ngwọta:Tinyegharịa ihe mmetụta pụọ na mpaghara condensation ma ọ bụ tinye mkpuchi hydrophobic.

Site n'ịgbasa ihe ndị a, ihe mmetụta NTC nwere ike hụ na arụ ọrụ a pụrụ ịdabere na ya na sistemụ AC, na-eme ka arụmọrụ ike dịkwuo mma (EER) na ịgbatị oge ndụ akụrụngwa.
