Sistemi za nadzor dima in toplote - 11. del: Prezračevalni sistemi z vodoravnim tokom za zaprta parkirišča
(1) Ta tehnična specifikacija določa minimalne zahteve glede zasnove, namestitve in začetka obratovanja za električne sisteme za nadzor dima in toplote na zaprtih parkiriščih, ki uporabljajo prezračevanje s horizontalnim kroženjem, z ali brez sprinklerske zaščite, na eni ali več ravneh, za avtomobile in lahka gospodarska vozila (največ 3,5 t), da se dosežejo cilji projektiranja, opisani v tej tehnični specifikaciji.
Glej cilje zasnove v določilih CEN TC191 SC1, dok. N721, 5.1 (1):
Sistem mora za vsako požarno lokacijo zagotavljati vsaj eno dostopno pot brez prevelike količine dima, ki gasilcem omogoča dostop z zunanje strani ali z zaščitene dostopne poti (npr. stopnišča) na razdalji 15 m od sprednje strani požara. Merila naj se preverijo, ko se na parkirišču vzpostavi stacionarno stanje.
OPOMBA: Meja 15 m je potrebna za doseganje ognja s curkom iz brizgalne cevi.
(2) Ta tehnična specifikacija se uporablja za goreče avtomobile na bencin, dizel ali druga goriva, ki bodo imeli podobne požarne lastnosti kot vozila na bencin ali elektriko. Ne uporablja se za druge požare na parkirišču (npr. skladišče).
OPOMBA: Predpostavlja se, da bodo imeli avtomobili na goriva, ki niso bencin ali dizel, podobne požarne lastnosti kot vozila na bencin ali dizel.
(3) Ta tehnična specifikacija zajema le tradicionalna parkirišča, kjer so avtomobili parkirani eden poleg drugega s skupnimi dovoznimi cestami/pasovi za vstop in izstop avtomobilov. Ne zajema drugih oblik sistemov za parkiranje avtomobilov, kot so sistemi za etažno parkiranje avtomobilov. Sistemi za nadzor dima in toplote za vozila, težja od 3,5 t (parkirišča za tovornjake, avtobusna parkirišča itd.), v tej tehnični specifikaciji niso zajeti.
(4) Ta tehnična specifikacija ne zajema zahtev za vsakodnevno prezračevanje.
(5) V tej tehnični specifikaciji poleg gorečih avtomobilov niso zajeta nobena druga tveganja.

Introduction
0.1 General
The requirements in this document are provided for powered smoke and heat control systems installed
in car parks with or without sprinkler protection.
Modern cars are generally larger than their predecessors and contain a larger quantity of flammable
materials, in particular plastics, which results in an increase of heat and smoke output from burning cars.
Consequently, the design fires recommended in this document are larger and have a greater heat and
smoke output than those in some previous guidance.
0.2 Purposes of smoke control systems
Smoke control systems can be generally designed for one or more of three purposes in the event of a fire:
— to protect means of escape from the car park;
— to provide an access sufficiently free of smoke for fire-fighters to a point close to the seat of the fire;
— to assist fire-fighters to clear smoke from a car park.
The system requirements will differ depending upon the purpose. Not all types of ventilation systems are
suitable for all purposes.
This document only covers smoke control systems which are intended to provide an access sufficiently
free of smoke for fire-fighters.
0.3 Smoke control systems to provide an access sufficiently free of smoke for fire-fighters
This document deals only with horizontal flow powered ventilation systems.
The following systems are not covered by this document however, they are briefly discussed here:
— Horizontal natural ventilation - These systems may be suitable for open car parks, where at each
level, ventilation openings are located on at least two opposite façades. The size of the ventilation
openings will need to meet the relevant national regulations.
— SHEVS – These systems are covered by the recommendations of CEN/TR 12101-5 for steady-
state design fires or prCEN/TR 12101-12 (under development) for time-dependent design fires.
Hot smoky gases from a fire rise up to the ceiling, where it spread to form a smoke layer above
the denser cold air beneath. SHEVS, which may be natural or powered, are designed and sized to
maintain conditions beneath the smoke layer that allow evacuation and/or firefighting
operations. Such a system
