COOSA (Carbon Dioxide System Analyzer) is a computer program developed over 20 years ago by professional fire protection engineers, mathematicians, and programmers for the design or review of CO2 fire suppression systems. The software permits easy data entry, on screen editing of system design criteria, quick calculations, and easy modification of data for recalculation. Calculations are based on two phase flow through balanced and unbalanced steel piping systems in accordance with NFPA 12 for high or low pressure, total flooding, or local application of CO2. Piping is sized automatically or manually. Results are also displayed on the screen, saved, and printed. The program includes NFPA Chapter 9 and IMO-FSS Chapter 5 (SOLAS) calculations for Marine Systems and a cost estimating utility which provides an inventory and cost report with each system calculation if desired.
By sizing piping automatically, COOSA is able to use the smallest pipes for nozzles, with branch and main pipe sizes at least as large as downstream piping (except at cylinders where dip tubes and valves will be smaller than the header). Pipe sizes are limited only by the Y-Z tables of NFPA-12, and desired pipe sizes can be “forced”. You will be able to determine the size and number of cylinders or tanks, the pipe sizes, nozzle orifice sizes, the pressure at each point, the flow rate in each pipe and the discharge time for low pressure or high pressure systems. CO2 piping systems for local or total flooding applications are relatively simple radial arrangements supplied by a group of cylinders (high pressure) or a refrigerated tank (low pressure). Discharge is through nozzles having orifice sizes calculated to meter the proper release of CO2. Cylinders may be sized on the basis of listed weight or volume and fill density.
COOSA is available in English or Spanish language formats with a user translation option for data entry and report headers. Each program is provided with English and Metric units and includes options for NFPA 12 Marine and SOLAS calculations.
Warning: CO2 systems produce lethal concentrations of gas when used for fire suppression. System design must include safety precautions to prevent release in occupied areas or migration into occupied areas, either accidentally or during a fire. NFPA-12 should be thoroughly reviewed and recommendations followed with regard to CO2 system design and related hazards.
