Hauv xyoo 1980s, kev tawm tsam thaum ntxov, cov lus teb ceev ceev (ESFR) cov tshuab nqus dej tau tsim los ua lwm txoj hauv kev hauv khib nyiab.Lawv tau tsim los txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau tua hluav taws, cov tshuaj tua hluav taws tau tsim los ua kom muaj zog los yog tua hluav taws.
Lawv ua haujlwm li cas?ESFR sprinklers yog tsim los tso tawm 2-3 npaug ntawm cov dej ntawm cov pa sprinkler taub hau thiab tso tawm cov tee dej loj dua, uas nyob rau hauv lem muaj lub zog ntau dua li cov tee tso tawm los ntawm cov taub hau.Yog li ntawd, cov dej ntau dua thiab ntau dua ntawm cov dej nce mus txog qhov hluav taws kub uas cia cov nplaim taws tua.

Daim ntawv thov

Feem ntau, ESFR cov tshuab tuaj yeem siv rau hauv cov tsev khaws khoom nrog qhov chaw cia uas tsis pub tshaj 40 feet ntawm qhov siab tag nrho, thiab nrog lub qab nthab qhov siab tsawg dua 45 feet.Thiab muaj cov txheej txheem kev tiv thaiv kab ke uas yuav tso cai cia siab tshaj qhov siab.Cov no tuaj yeem suav nrog hauv khib nyiab los yog kev sib xyaw ntawm ESFR nrog rau hauv khib nyiab.
ESFR systems yog tsim los tiv thaiv ntau yam khoom muag.Qhov no muab kev hloov pauv ntau dua hauv kev ua haujlwm hauv tsev khaws khoom thaum piv rau kev tswj hwm hom (paub) cov tshuab nqus dej, uas yog tsim los tiv thaiv cov khoom lag luam uas tau khaws cia thaum lub sijhawm teeb tsa.Yog tias qhov xwm txheej khaws cia yuav tsum tau muab tso rau hauv-rack sprinklers yuav tsum tau muab tso rau hauv cov txheej txheem tswj uas twb muaj lawm ntawm lub tsev khaws khoom, feem ntau cov tswv tsev nyiam hloov mus rau ESFR, tsuas yog vim li ntawd tsis tas yuav txhawj xeeb txog kev puas tsuaj hauv cov khib nyiab lub taub hau thaum lub sijhawm. ib txwm cia ua haujlwm.Tsis tas li ntawd, nyob rau hauv-rack sprinklers yuav tsum tau muab tshem tawm thiab qee zaum hloov nrog txhua tus neeg xauj tsev tshiab, vim cov neeg xauj tsev muaj cov racks.Yog li ntawd, hloov mus rau ESFR system yog lub sij hawm ntau tus nqi-zoo nyob rau lub sijhawm ntev.
