1. INTRODUZIONE Nel calcolo per il dimensionamento e la verifica degli impianti di spegnimento a gas Argon IG-01 è stato utilizzato un software di calcolo appositamente predisposto dalla ditta VdS Verband der Schadenverhuetung (Koeln Germania) conforme alle specifiche NFPA 2001, versione 7.2. I dato tecnici dell ARGON IG-01 si possono riassumere nella seguente tabella denominazione chimica Argon purezza > 99.9% densità a 15 C e 1013 mbar 1,69 Kg/ m 3 rigidità dielettrica relativa a 1 atm - mmhg a + 25 C (N 2 = 1,0) 1,01 concentrazione di progetto (% in volume) 38% 50% capacità bombole litri 80 quantità in volume di Argon nella bombola con carica a 300 bar Nm 3 25 ~ * quantità in peso di Argon nella bombola con carica a 300 bar Kg. 40,27 ~ estinguente inserito nello Standard internazionale UNI EN 15004 e nella normativa NFPA 2001 con la sigla IG-01 Con il Sistema Argon la concentrazione di progetto varia, a seconda del rischio, dal 41,9% al 52%, garantendo una riduzione di ossigeno non inferiore al 10% e non superiore al 14% in volume, con un atmosfera sicura per le persone ed efficace per lo spegnimento. Nei calcoli allegati è stata calcolata una concentrazione di progetto di Argon (IG-01) per superficie di Classe A (carta, legno, ecc.) pari a 41,9% in volume UNI ISO 14520-12 e UNI EN 15004-7 con un tempo di scarica pari a 60 secondi. Il tempo di scarica viene definito come il tempo necessario per raggiungere il 95% della concentrazione minima di progetto. Al fine di garantire al Sistema Argon una efficace azione estinguente entro i tempi di intervento sopra menzionati, è necessario dimensionare la capacità delle bombole sotto pressione contenenti il gas inerte sulla base dell effettiva cubatura dei locali. Dall analisi di tali dati, si evidenzia quanto riportato nella tabelle sottostanti per i vari presidi antincendio 2
