Kuzindikira chinyezi ndi kutentha n'kofunika kwambiri, makamaka m'nyengo yozizira yomwe ambiri a ife tikukumana nayo panopa. N'kofunika osati pa moyo watsiku ndi tsiku, komanso m'makampani opanga zinthu. Mwachitsanzo, pamene ma transmitter a chinyezi ayikidwa bwino ndikugwiritsidwa ntchito, makina odziyimira pawokha omanga nyumba amatha kudziwa nthawi yomwe mpweya umakhala wouma kwambiri kapena wonyowa kwambiri kuti ukhale womasuka.
Ndiye kodi sensa ya kutentha ndi chinyezi imagwira ntchito bwanji?
Choyamba, Sensa ya Kutentha
Masensa otenthetsera amagwiritsidwa ntchito kudziwa kuchuluka kwa kutentha kapena kuzizira komwe kumapangidwa ndi chinthu kapena makina. Amatha kuzindikira/kuzindikira kusintha kulikonse kwa kutentha ndi zizindikiro zotulutsa za analog kapena digito. Masensa otenthetsera amagawidwa m'magulu awiri: Masensa otenthetsera ayenera kukhala olumikizana ndi chinthucho kuti amve ndikuwunika kusintha kwa kutentha kudzera mu conduction. Masensa otenthetsera amawunika kusintha kwa kutentha pogwiritsa ntchito convection ndi radiation.
Chachiwiri,Chowunikira Chinyezi
Chinyezi ndi kuchuluka kwa nthunzi ya madzi mumlengalenga. Kuchuluka kwa nthunzi ya madzi mumlengalenga kumakhudza chitonthozo cha anthu ndi njira zosiyanasiyana zamafakitale. Nthunzi ya madzi imakhudzanso njira zosiyanasiyana zakuthupi, zamakemikolo ndi zamoyo. Zoseweretsa za chinyezi zimagwira ntchito pozindikira kusintha kwa mphamvu yamagetsi kapena kutentha kwa mpweya. Pali mitundu itatu yoyambira ya zoseweretsa za chinyezi: capacitive, resistive ndi thermal. Mtundu uliwonse mwa mitundu itatuyi udzayang'anira nthawi zonse kusintha pang'ono mumlengalenga kuti uwerengere chinyezi cha mpweya.
Chojambulira chinyezi cha capacitiveZimazindikira chinyezi mwa kuyika mzere woonda wa chitsulo pakati pa ma electrode awiri. Mphamvu yamagetsi ya ma oxide achitsulo imasiyana malinga ndi chinyezi cha mlengalenga wozungulira. Ntchito zazikulu ndi nyengo, zamalonda ndi mafakitale. Ma sensor a chinyezi chotsutsa amagwiritsa ntchito ma ayoni mu mchere kuti ayesere kuponderezedwa kwa magetsi kwa maatomu. Kukana kwa ma electrode mbali zonse ziwiri za mchere kumasintha ndi chinyezi. Ma sensor awiri otentha amachititsa magetsi kutengera chinyezi cha mpweya wozungulira. Sensa imodzi imatsekedwa mu nayitrogeni youma, pomwe ina imawonetsedwa ndi mpweya wozungulira. Kusiyana pakati pa mitundu iwiriyi kumasonyeza chinyezi chapadera.
Chowunikira chinyezindi chipangizo chamagetsi chomwe chimazindikira chinyezi m'chilengedwe ndikuchisintha kukhala chizindikiro chamagetsi. Zosefera za chinyezi zimabwera m'makulidwe ndi mawonekedwe osiyanasiyana; Zina zimaphatikizidwa muzipangizo zonyamulidwa m'manja, monga mafoni a m'manja, pomwe zina zimaphatikizidwa muzipangizo zazikulu zolumikizidwa, monga machitidwe owunikira mpweya wabwino. Mwachitsanzo, Zotumiza kutentha ndi chinyezi ku Hengko amagwiritsidwa ntchito kwambiri muamafakitale a zanyengo, zamankhwala, zamagalimoto ndi mafakitale a HVAC komanso opanga. Chowunikira chinyezi chapamwamba kwambiri cha kalasi yamafakitale chingathandize kuonetsetsa kuti muyeso wolondola uli m'malo ovuta kwambiri.
Chachitatu, Njira Yowerengera
Masensa a chinyezi amagawidwa m'magulu a masensa a chinyezi (RH) ndi masensa a chinyezi (AH) malinga ndi njira yomwe imagwiritsidwa ntchito powerengera chinyezi. Mayeso a chinyezi chogwirizana amatsimikiziridwa poyerekeza kuwerengera kwa chinyezi nthawi yeniyeni pa kutentha kwina ndi chinyezi chochuluka chomwe chili mumlengalenga pa kutentha kumeneko. Chifukwa chake, sensa ya chinyezi chogwirizana iyenera kuyeza kutentha kuti iwerengere chinyezi chogwirizana. Mosiyana ndi zimenezi, chinyezi chokhazikika chimatsimikiziridwa mosasamala kanthu za kutentha.
Choyamba, Kugwiritsa Ntchito Masensa
Masensa oyezera kutentha ali ndi ntchito zambirimbiri, chifukwa amagwiritsidwanso ntchito m'zida zosiyanasiyana zamankhwala, kuphatikizapo zida zoyezera kutentha kwa maginito (MRI) ndi ma scanner onyamulika a ultrasound. Masensa oyezera kutentha amagwiritsidwa ntchito m'zida zosiyanasiyana m'nyumba mwathu, kuyambira mafiriji ndi mafiriji mpaka mastovu ndi ma uvuni kuti atsimikizire kuti akutenthedwa kutentha koyenera pophikira, maswiti ampweya/zotenthetsera. Ngakhale ma charger wamba a batri amagwiritsa ntchito izi kuti apewe kudzaza kwambiri kapena kuchepetsa mphamvu ya batri kutengera kutentha kwake.
Ngakhale zingawoneke ngati sizingatheke kuti kuchotsa mafuta kugwiritsidwe ntchito poyezera kutentha, ndikofunikira kuti zitsimikizire kuti njira zochotsera mafuta zili zotetezeka komanso zothandiza. Chogwirira cha mafuta chili ndi choyezera kutentha kumapeto kwake chomwe chimadziwitsa ogwira ntchito ngati chikufunika kusiya kuboola, chifukwa kutentha kwambiri kukayamba (chifukwa chimapitiriza kuboola pansi), kumatha kutentha kwambiri ndikusweka.
Sensa yotenthetsera imayikidwa mu radiator ya galimoto. Izi ndizofunikira kwambiri, chifukwa madzi akamadutsa mu injini ya galimoto akafika kutentha kwambiri, amakuchenjezani kuti, ngati atapitirira, angayambitse kulephera kwa injini, komanso kuwongolera nyengo ya galimotoyo. Mwa kusintha zokha magawo malinga ndi kutentha, vutoli limapewedwa bwino popanda kuyika dalaivala pachiwopsezo.
Machitidwe a HVACamafunika kuyeza kutentha kuti athandize kusunga kutentha koyenera m'chipinda kapena m'nyumba. Zoyezera kutentha zimafunika pafupifupi m'zipinda zonse zoziziritsira mpweya ndi makina m'nyumba ndi m'maofesi. Zingagwiritsidwenso ntchito kuzindikira kutuluka kwa madzi mwa kuzindikira zinthu zosayembekezereka za kutentha.
Mphamvu zongowonjezedwanso zimadalira masensa otenthetsera kuti azigwira ntchito bwino. Mapampu otenthetsera a dzuwa, ma turbine amphepo, kugwiritsa ntchito biomass kuyaka ndi magwero a kutentha pansi zonse zimadalira malamulo ndi muyeso wa kutentha.
Chachisanu, Kulinganiza Molondola
Kuti tidziwe kulondola kwa sensa, zomwe zapezeka zimayerekezeredwa ndi muyezo wofotokozera. Kuti titsimikizire kulondola kwa masensa a chinyezi, tidapanga miyezo pogwiritsa ntchito njira ya "saturated salt". Mwachidule, pamene mchere wina (mankhwala a ionic monga mchere wa tebulo kapena potassium chloride) usungunuka m'madzi, umapanga mlengalenga wa chinyezi chodziwika.
Izikatundu wa mankhwalaamagwiritsidwa ntchito popanga malo okhala ndi chinyezi chodziwika bwino (RH) (muyezo wofotokozera), womwe umawerengedwa ndi sensa. Mwachidule, tidzakonza yankho mu thanki yotsekedwa kuti ligwire mlengalenga, kenako tidzayika sensa yolumikizidwa mu thanki yotsekedwa. Pambuyo pake, sensa imawerengedwa mobwerezabwereza ndipo miyeso imalembedwa.
Tikhoza kupanga ma profiles a sensa yomwe ikuyesedwa pobwereza njirayi ndi mchere wosiyanasiyana, womwe umapanga chinyezi chosiyana. Chifukwa timadziwa chinyezi cha microenvi iliyonse.rmgwirizano, tikhoza kufananizasensakuwerenga ndi mfundo zodziwika bwino kuti mudziwe kulondola kwa sensa.
Ngati kusiyana kuli kwakukulu koma sikungatheke, titha kukonza kulondola kwa muyeso pogwiritsa ntchito njira yowerengera masamu mu pulogalamuyo.
