zdravim.. vyvijam si automaticke hasiace zariadenie do serverovne a riesim poslednu otazku...
aky hasiaci plyn a preco pouzit...
cenovo najlepsie vychadza CO2 ale zatial som na hasenie vydel iba halonove a podobne chlorflourbrom divnoplyny
je tam issiue s efektivitou alebo zo zdravim?
co2 dokaze vytlacit kyslik zo vzduchu a nie je tam mozne niaku dobu fungovat... ale to iste robi aj halon... |

ok uz som mudrejsi...
co2 potrebuje koncentraciu aspon 30% (idealne 50%) ktora je smrtelna pre osadku...
halonu staci menej kedze reaguje chemicky s poziarom..
kedze je to uzavrety priestor a pretlakovy odpad je vyvedeny do exterieru a ludia sa tam nachadzaju tak 2 hodiny do mesica je pre mna idealne co2
dakujem za diskusiu  |

Co viem od chalanov, ktori montovali hasiace systémy pre datacentrá pouzival sa tam nejaky plyn FM200
Hasiace medium by nemalo byt zdraviu skodlive kedze tam niekto moze ostat.... |

to povazujem za uplny nezmysel...
staci trosku necistoty v zariadeniach a voda sa znovu stane vodivou a papa...
skor mi to pride ako marketing ze eko hento zelene tamto... |

| proti prirodnej sile - vode je celkom ucinne pouzit inu prirodnu silu - gravitaciu... mat datacentrum na vyvysenom mieste. pchat serverovne do suterneov a prizemi (ako to robi vela ludi) je dost kratkozrake. a proti pohrome zhora (prasknute potrubie) je tiez jednoduche riesenie - netahat potrubia ponad serverovnou... |

to sa da len ked mas naozaj novu stavbu...
my mame privatne DCcko na urovni terenu (prizemie), ale kedze cela petrzalka je zatopove pasmo tak je to trosku problem...
snad nas nevytopi... |
