Hunhu hwemhepo, kungave mukati kana kunze, hunokanganisa zvakanyanya nevolatile organic compounds (TVOCs). Izvi zvinosvibisa zvisingaoneki zviriko zvakafara uye zvinounza njodzi huru dzeutano. TVOC yekutarisa michina inopa chaiyo-nguva data paTVOC kutariswa, ichigonesa kufefetedza uye nzira dzekuchenesa kuvandudza mhando yemhepo.sensor yezwikushanda? Ngatizviparadze.
Chii chinonzi TVOCs?
TVOCs (Total Volatile Organic Compounds) kureva kuungana kwese kwekemikari inoputika mumhepo. Zvinosanganisira:
Alkanes-yakabudiswa kubva kupende, zvinonamira, uye mukati memotokari (mapurasitiki, rubber).
Alkenes-iripo mudzimba dzemumugwagwa (motikari), nzvimbo dzekusvuta, kana magaraji ane zvigadzirwa zverabha.
Inonhuhwirira hydrocarbons-inobudiswa kubva mupendi yemudhuri, fenicha itsva, saroni dzezvipikiri, uye mashopu ekudhinda.
Halogenated hydrocarbons-zvinowanzoitika pedyo nemichina yakaoma yekugezesa uye makicheni uchishandisa solvent-based cleaning products.
Aldehydes uye ketoni-Matusi makuru anosanganisira fenicha yehuni yakagadzirwa, saroni dzezvipikiri, uye utsi hwefodya.
Esters-inowanikwa muzvizoro, makamuri evana akazadzwa nematoyi, kana mukati akashongedzwa nePVC zvinhu.
Mamwe maVOC anosanganisira:
Doro (methanol kubva kupendi solvents, ethanol kubva kudoro evaporation),
Ethers (glycol ethers mune coatings),
Amines (dimethylamine kubva mukuchengetedza uye detergents).
Sei Kuongorora TVOCs?
TVOCs haisi imwe chete inosvibisa asi kusanganiswa kwakaoma kwemakemikari ane zvakasiyana-siyana. Yakanyanya kuwanda inogona kukuvadza zvakanyanya hutano hwevanhu:
Kuratidzwa kwenguva pfupi-musoro, kutsamwa kweziso/mhino.
Kuratidzwa kwenguva refu-ngozi yekenza, kusagadzikana kwehurongwa hwemitsipa, uye kushaya simba kwekuzvidzivirira.
Kuongorora kwakakosha nekuti:
Indoors-chaiyo-nguva kuyerwa inobvumira kufefetedza, kusefa (semuenzaniso, activated kabhoni), uye sosi control (uchishandisa eco-hushamwari zvinhu).
Kunze-kuonekwa kunobatsira kuona kusvibisa masosi, kutsigira kugadzirisa, uye kusangana nemirairo yezvakatipoteredza.
Kunyangwe munzvimbo dzisina kugadziridzwa, mabasa ezuva nezuva (kuchenesa, kusvuta, kubika, kuparara kwemarara) kuburitsa yakaderera mazinga eVOCs, izvo zvinogona kukonzera kusagadzikana kwehutano nekufamba kwenguva. Kuongorora kwesainzi kunoshandura njodzi idzi dzisingaoneki kuita zvinhu zvinogoneka.
TVOC Sensors Inoshanda Sei?
TVOC yekutarisa michina inoshandisayakasanganiswa gasi sensors izvo zvinonzwa kune akawanda anopisa anosvibisa, kusanganisira:
Formaldehyde
Toluene
Ammonia
Hydrogen sulfide
Carbon monoxide
Doro mhute
Utsi hwefodya
Aya ma sensor anogona:
Providechaiyo-nguva uye yenguva refu yekutarisa.
Ratidza concentrations uye buritsa chenjedzo kana mazinga akadarika zvikumbaridzo.
Batanidza neventilation uye yekuchenesa masisitimu kuitira mhinduro otomatiki.
Tumira data kuburikidza nekutaurirana interfaces kune makore maseva kana kuvaka manejimendi masisitimu (BMS).
Zvishandiso zveTVOC Sensors
Nzvimbo dzepachena dzemukati-inoshandiswa muHVAC, BMS, uye IoT masisitimu.
Kuchengetedzeka kwemaindasitiri uye kutevedzera-kudzivirira chepfu uye njodzi dzinoputika mumafekitori uchishandisa zvinonyungudutsa, mafuta, kana pendi.
Motokari uye zvekufambisa- tarisa kabhini yemhando yemhepo uye kuderedza kuratidzwa kune epositi emissions.
Dzimba dzakangwara uye zvigadzirwa zvevatengi-yakabatanidzwa mune thermostats, purifiers, uye kunyange kupfeka.

Zvakanakira
Kuonekwa kusingadhuri kwezvizhinji zvinosvibisa
Kuderera kwesimba rekushandisa, kugadzikana kwekutarisa kwenguva refu
Inovandudza kuchengetedzwa kwemhepo uye kutevedzera mitemo

Kuganhurirwa
Haikwanise kutarisa marudzi ese eVOC
Haikwanise kuziva zvinosvibisa munhu nemazvo

FAQs
1. Masensa eTVOC anoonei?
Ivo vanoyera huwandu hwese hwehuwandu hwemagetsi organic compounds, asi kwete chaiwo magasi.
2. Masensa eTVOC akarurama here?
Kurongeka kunoenderana nerudzi rwe sensor uye calibration yemugadziri. Nepo hunhu hwakakwana hunogona kusiyana, kushandiswa kwakafanana kunopa maitiro ekutarisa akavimbika.
3. Ko masensa eTVOC anoda kuchengetedzwa here?
Ehe. PID sensors inoda gore negore calibration; semiconductor sensors kazhinji inoda kudzokorora makore 2-3 ega ega.
4. Ko TVOC sensors inogona kuona magasi ose anokuvadza here?
Aiwa
5. Masensa eTVOC anoshandiswa kupi?
Mudzimba, mahofisi, zvikoro, zvipatara, zvitoro zvikuru, nzvimbo dzokutakura zvinhu, motokari, mafekitari, uye michina yokupinza mhepo.
6. Masensa eTVOC akakodzera kushandiswa pamba here?
Ehe. Izvo zvakachengeteka, zviri nyore kuisa, uye zvinopa chaiyo-nguva yemhepo chenjedzo.
Mhedziso
TVOC masensa anotamba abasa rinokosha mukuchengetedza hutano, kuvandudza kunaka kwemhepo, uye kuve nechokwadi chekuchengetedza mumaindasitiri uye mazuva ese. Kubva kudzimba nemahofisi kuenda kumota nemafekitari, vanoshandura “zvisingaoneki zvinotyisidzira” kuita data inoyerwa, vachipa vanhu simba rekutora matanho ekusimudzira nharaunda ine hutano.
