PROperties of FIre Suppressant SYstems: "PROFISSY" - A Spreadsheet Application for Fire-Suppressant Bottle-Filling Calculations

Description

This spreadsheet and accompanying files are the result of work performed for U.S. Army Ground Vehicle Systems Center by the National Institute of Standards and Technology (NIST), Applied Chemicals and Materials Division on the development of a computer program for fire-suppressant bottle-filling calculations under interagency agreement number 11478007. The work includes the development of an Excel spreadsheet that is to be used with the NIST23 (REFPROP) (that must be obtained separately at https://www.nist.gov/srd/refprop) to provide two bottle-filling calculations (1) given vessel size, mass of agent, mass of pressurizing agent, and filling temperature compute the filling pressure, and the temperature and pressure conditions at which the fluid in the vessel becomes single phase, and (2) given the vessel size, mass of agent, and filling temperature and pressure, compute the mass of pressurizing fluid, and the temperature and pressure conditions at which the fluid in the vessel becomes single phase. The agents include CF3I, R-218, R-125, R-227ea, R 13B1, R-236fa, HFE-7100, Novec 649 (also known as Novec 1230 and FK-5-1-12), R 1233zd(E), R-1336mzz(Z), and R1336-mzz(E). Two pressurizing agents are available, nitrogen and carbon dioxide. There also is an option to include solid sodium bicarbonate powder in the calculations, and the ability to generate tables of conditions in the vessel as a function of temperature summarized with simple graphics.

57 This zip file contains the Excel spreadsheet PROFISSY.version1.0.xlsm and additional files HFE7100.fld, R13B1.fld and HMX.BNC that are necessary for the model implementation. The spreadsheet is documented in NIST Technical Note 2132, available at https://doi.org/10.6028/NIST.TN.2132. It is necessary to have NIST Refprop installed as well, this is a separate program available for purchase at https://www.nist.gov/srd/refprop. The Dll must be greater than or equal to 10.0.0.87. https://data.nist.gov/od/ds/mds2-2333/PROFISSY.release.zip
