Cov qauv tsim tsis ntev los no ntawm lub tshuab nqus tsev vacuum tau nce ntxiv nrog HEPA lim. Cov cuab yeej zoo li no cuam tshuam nrog cov khoom uas tuaj yeem pom tsuas yog nrog lub tshuab tsom.
History of Creation
Highly Efficient Particle Containment - qhov no yog li cas cov ntawv luv HEPA tau txhais los ntawm Askiv. Cov cuab yeej thiab cov khoom siv ntawm cov lim dej no tso cai rau peb faib lawv ua cov khoom siv tu zoo.
Lawv tau tsim nyob rau hauv lub xyoo pua xeem, nyob rau hauv lub forties, thaum tsim lub atomic bomb project. Lub hom phiaj ntawm cov ntxaij lim dej no yog tshem tawm cov xov tooj cua tsis huv. Tom qab qee lub sijhawm, thaj tsam ntawm kev tu cov cuab yeej tau nthuav dav heev. Lawv tau pib siv rau hauv engineering engineering thiab hauv tsev kho mob, hauv kev lag luam tshuaj thiab zaub mov, nrog rau cov khoom siv hauv tsev.
HEPA lim yog dab tsi? Qhov kev ua haujlwm siab particle retention device yog tsim los ntawm cov cellulose fiber zoo. Thaum lub sijhawm ua haujlwm ntawm lub tshuab nqus tsev, cov plua plav tawm ntawm lub network tsim los ntawm qhov tsawg tshaj plaws pores. Tib lub sijhawm, txawm tias qhov me me uas muaj qhov loj ntawm 0.3 microns tau khaws cia.
HEPA lim yog tsim los siv cov cuab yeej tshwj xeeb. Nws lub ntsiab caiyog nias ntawm txheej ntawm cellulose thiab lawv layout nyob rau hauv daim ntawv ntawm ib tug accordion. Qhov no tso cai rau koj kom loj hlob thaj tsam ntawm qhov chaw lim dej. Lub cellulose accordion yog tsau nrog ib daim phiaj reinforcing.
HEPA lim tuaj yeem muab pov tseg. Hauv qhov no, fiberglass ntxiv rau cellulose thaum nws tsim khoom. Lub HEPA lim rov siv tau yog tsim los ntawm PTFE fibers.
Purpose
Cov lim rau kev ntxuav zoo heev yog siv thaum ntxuav chav nrog lub tshuab nqus tsev. Lawv tso cai rau koj kom tshem tawm cov kab mob thiab cov allergens. Cov khoom me tshaj plaws kuj tau ntes tau zoo heev. Cov txheej txheem no muaj peev xwm ua tau raws li qhov kev txiav txim ntawm HEPA lim mechanisms hauv qab no:
- cov nyhuv ntawm cov khoom ntes ntawm microfibers;
- cov nyhuv ntawm inertia, uas yog qhia rau cov khoom loj; - cov nyhuv diffusion, uas yog feem ntau tshaj tawm ntawm qis airflow speeds.
Lub HEPA lim puas tuaj yeem ntxuav tau?
Muaj qee lub sijhawm thaum cov ntxhiab tsw ntxhiab tsw zoo ntawm cov plua plav tshwm thaum lub tshuab nqus tsev. Qhov no yuav txhais tau tias lub lim tau tas sij hawm thiab tau tso tseg cov khoom uas nws tau tsim. Txhawm rau kho qhov teeb meem, koj yuav tsum hloov cellulose accordion nrog ib qho tshiab. Koj tuaj yeem ntxuav nws yooj yim. Txawm li cas los xij, cov txheej txheem no tsuas yog ua tau yog tias lub lim dej yog hom dej tsis zoo. Cov ntsiab lus ntawm kev hloov pauv thiab kev ntxuav yog qhia hauv cov lus qhia rau lub tshuab nqus tsev vacuum.
Modern Samsung lub tshuab nqus tsev tsis muaj hnab plua plav. Yooj yimcov khib nyiab thiab av nyob hauv ib lub thawv yas tshwj xeeb. Tsis tas li ntawd, lub tshuab nqus tsev yog nruab nrog ob lub lim dej. Ib tug ntawm lawv ntxuav cov huab cua thaum nws nqus rau hauv, thiab lwm yam thaum nws tawm hauv lub tshuab nqus tsev vacuum. Qhov no yog HEPA tso zis lim rau Samsung hom H 11. Nws yog waterproof. Thaum qias neeg, yaug hauv dej sov tsawg kawg ob lossis peb zaug hauv ib xyoos.
