Nyob rau theem siab tshaj, dampers muaj ob daim ntawv thov sib txawv: HVAC (cua sov, qhov cua thiab cua txias) daim ntawv thov thiab cov txheej txheem kev lag luam. Kab lus no tsom ntsoov rau feem ntau ntawm damper hom rau cov txheej txheem kev lag luam, txawm hais tias muaj qee qhov sib txawv ntawm qhov sib txawv.
Lub damper yog ib qho khoom siv uas siv cov hniav hloov tau los tswj cov cua ntws los ntawm ib sab ntawm lub damper mus rau lwm qhov, thiab nws yuav nyob hauv ib lub ductwork, nruab nrab ntawm chav, los yog nruab nrab ntawm sab nrauv thiab sab hauv ntawm lub tsev.
Dampers yog ntau tshaj li cov cua dampers yooj yim. Lawv yog qhov tseem ceeb rau kev tswj kom txias, sov, kub, qias neeg thiab txawm tias huab cua tsis zoo. Lawv kuj siv tau rau kev tiv thaiv hluav taws. Dampers tswj huab cua zoo thiab muab kev nyab xeeb rau cov neeg ua haujlwm, uas yog vim li cas lawv yog qhov tseem ceeb rau kev tswj hwm huab cua.
Tsis tas li ntawd, dab tsi ua rau dampers qhov kev xaiv zoo tshaj plaws rau cov tshuab loj thiab cov txheej txheem yog ntau yam kev tsim muaj - qhov no ua rau koj yooj yim xaiv hom damper uas zoo tshaj plaws haum rau koj cov txheej txheem kev lag luam.
Txawm li cas los xij, xaiv qhov kev xaiv zoo tuaj yeem ua rau tsis meej pem thiab ua rau koj xav tsis thoob: tawm ntawm ntau hom dampers, qhov twg yog qhov zoo rau koj?
Feem ntau, txhua tus muaj lub hom phiaj tshwj xeeb, thiab xaiv qhov tsim tsim yog qhov tseem ceeb rau kev ua haujlwm ntev, ruaj khov.
Hauv phau ntawv qhia no, peb yuav taug kev koj los ntawm hom kev lag luam dampers thiab lawv cov ntawv thov los pab koj txiav txim siab.
