Ubwino wa mpweya, kaya m'nyumba kapena panja, umakhudzidwa kwambiri ndi zinthu zachilengedwe zosinthasintha (TVOCs). Zinthu zodetsa zosaonekazi zimapezeka kwambiri ndipo zimayambitsa zoopsa zazikulu paumoyo. Zipangizo zowunikira TVOC zimapereka deta yeniyeni pa kuchuluka kwa TVOC, zomwe zimathandiza njira zopumira mpweya ndi kuyeretsa kuti ziwongolere ubwino wa mpweya. Koma kodi zimatero bwanji kwenikweni?sensa ya mawuntchito? Tiyeni tikambirane mwachidule.
Kodi TVOCs ndi chiyani?
Ma TVOC (Mafakitale Onse Osasinthasintha a Zachilengedwe) amatanthauza kuchuluka konse kwa mankhwala onse osinthika mumlengalenga. Izi zikuphatikizapo:
Ma Alkanes-yopangidwa kuchokera ku utoto, zomatira, ndi mkati mwa galimoto (pulasitiki, rabala).
Alkenes-zimapezeka m'nyumba zomwe zili m'mbali mwa msewu (motengera utsi wa galimoto), m'malo osungira utsi, kapena m'magalaji okhala ndi zinthu zopangidwa ndi rabara.
Ma hydrocarbon onunkhira-zotulutsidwa kuchokera ku utoto wa pakhoma, mipando yatsopano, malo okonzera misomali, ndi malo ochitira ntchito zosindikizira.
Ma hydrocarbon okhala ndi halogenated-zotsukira zouma ndi khitchini zomwe zimapezeka kwambiri pafupi ndi malo otsukira pogwiritsa ntchito zinthu zotsukira zopangidwa ndi zosungunulira.
Ma Aldehydes ndi ma ketones-zinthu zazikulu zikuphatikizapo mipando yamatabwa yopangidwa ndi akatswiri, malo okonzera misomali, ndi utsi wa fodya.
Ma Esters-amapezeka mu zodzoladzola, zipinda za ana zodzaza ndi zoseweretsa, kapena mkati mwake zokongoletsedwa ndi zinthu za PVC.
Ma VOC ena ndi awa:
Mowa (methanol yochokera ku zosungunulira utoto, ethanol yochokera ku nthunzi ya mowa),
Ma ether (ma ether a glycol mu zokutira),
Ma Amine (dimethylamine yochokera ku zosungira ndi zotsukira).
Chifukwa chiyani muyenera kuyang'anira TVOCs?
Ma TVOC si chinthu chimodzi choipitsa mpweya koma ndi mankhwala osiyanasiyana. Kuchuluka kwa mankhwala m'thupi kungawononge kwambiri thanzi la anthu:
Kuwonekera kwakanthawi kochepa-kupweteka mutu, kuyabwa m'maso/mphuno.
Kuwonekera kwa nthawi yayitali-chiwopsezo cha khansa, matenda a mitsempha, komanso chitetezo chamthupi chofooka.
Kuwunika ndikofunikira chifukwa:
M'nyumba-kuyeza nthawi yeniyeni kumalola mpweya wabwino, kusefa (monga, kaboni woyatsidwa), ndi kuwongolera magwero (pogwiritsa ntchito zipangizo zosamalira chilengedwe).
Kunja-kupeza kumathandiza kuzindikira magwero a kuipitsa, kuthandizira kukonza, komanso kukwaniritsa malamulo okhudza chilengedwe.
Ngakhale m'malo osakonzedwanso, zochita za tsiku ndi tsiku (kuyeretsa, kusuta fodya, kuphika, kuwononga zinyalala) zimatulutsa ma VOC ochepa, zomwe zingayambitse mavuto aakulu azaumoyo pakapita nthawi. Kuwunika kwa sayansi kumasintha zoopsa zosaonekazi kukhala zinthu zomwe zingatheke.
Kodi Masensa a TVOC Amagwira Ntchito Bwanji?
Kugwiritsa ntchito zipangizo zowunikira TVOCmasensa osakaniza a gasi zomwe zimakhudzidwa ndi zinthu zambiri zoipitsa mpweya, kuphatikizapo:
Formaldehyde
Toluene
Amoniya
Hydrogen sulfide
Mpweya wa kaboni
Nthunzi ya mowa
Utsi wa ndudu
Masensa awa akhoza:
Perekanikuyang'anira nthawi yeniyeni komanso kwa nthawi yayitali.
Kuchuluka kwa chiwonetsero ndikupereka machenjezo pamene milingo ikupitirira malire.
Gwirizanitsani ndi njira zopumira mpweya ndi zoyeretsera kuti ayankhe okha.
Tumizani deta kudzera mu njira zolumikizirana ndi ma seva amtambo kapena machitidwe oyang'anira nyumba (BMS).
Kugwiritsa Ntchito Ma TVOC Sensors
Malo opezeka anthu onse m'nyumba-yogwiritsidwa ntchito mu machitidwe a HVAC, BMS, ndi IoT.
Chitetezo cha mafakitale ndi kutsatira malamulo-kuletsa poizoni ndi kuphulika kwa zinthu m'mafakitale pogwiritsa ntchito zosungunulira, mafuta, kapena utoto.
Magalimoto ndi mayendedwe-kuyang'anira mpweya wabwino m'chipindamo ndikuchepetsa kukhudzidwa ndi utsi woipa.
Nyumba zanzeru ndi zinthu zogulira-yophatikizidwa mu ma thermostat, zotsukira, komanso zovala.

Ubwino ndi Zofooka
Ubwino
Kuzindikira zinthu zoipitsa mpweya zambiri pogwiritsa ntchito ndalama zochepa
Kugwiritsa ntchito mphamvu zochepa, kokhazikika kuti ziwunikire kwa nthawi yayitali
Zimathandiza kuti chitetezo cha ndege chizitsatira malamulo komanso kuti zinthu ziyende bwino.
Kulumikizana kwa mtambo kuti muwongolere mwanzeru
Zoletsa
Sizingatheke kuyang'anira mtundu uliwonse wa VOC
Sitingathe kuzindikira bwino zinthu zoipitsa munthu payekha
Kuzindikira kumasiyana pakati pa opanga - mtengo weniweni sufanana mwachindunji
Magwiridwe antchito amakhudzidwa ndi kutentha, chinyezi, ndi kusuntha kwa masensa
Mafunso Ofunsidwa Kawirikawiri
1. Kodi masensa a TVOC amazindikira chiyani?
Amayesa kuchuluka konse kwa mankhwala osinthika achilengedwe, koma osati mpweya weniweni.
2. Kodi masensa a TVOC ndi olondola?
Kulondola kumadalira mtundu wa sensa ndi kuwerengera kwa wopanga. Ngakhale kuti miyezo yeniyeni ingasiyane, kugwiritsa ntchito nthawi zonse kumapereka njira zodalirika zowunikira.
3. Kodi masensa a TVOC amafunika kukonzedwa?
Inde. Masensa a PID amafunika kuyesedwa pachaka; masensa a semiconductor nthawi zambiri amafunika kuyesedwanso zaka ziwiri kapena zitatu zilizonse.
4. Kodi masensa a TVOC amatha kuzindikira mpweya wonse woipa?
Ayi. Pa zinthu zinazake zoipitsa mpweya, masensa apadera a mpweya umodzi kapena wa gasi wambiri amafunika.
5. Kodi masensa a TVOC amagwiritsidwa ntchito kuti?
M'nyumba, maofesi, masukulu, zipatala, m'masitolo akuluakulu, m'malo oyendera anthu, m'magalimoto, m'mafakitale, ndi m'makina opumira mpweya.
6. Kodi masensa a TVOC ndi oyenera kugwiritsidwa ntchito kunyumba?
Inde. Ndi otetezeka, osavuta kuyika, ndipo amapereka machenjezo okhudza mpweya wabwino nthawi yeniyeni.
Mapeto
Masensa a TVOC amaseweraudindo wofunikira poteteza thanzi, kukonza mpweya wabwino, ndikuonetsetsa kuti chitetezo chili bwino m'mafakitale ndi m'malo atsiku ndi tsiku. Kuyambira m'nyumba ndi maofesi mpaka magalimoto ndi mafakitale, amasintha "ziwopsezo zosaoneka" kukhala deta yoyezeka, kupatsa anthu mphamvu kuti achitepo kanthu mwachangu kuti akhale ndi malo abwino.
