I am working on an existing Low Pressure CO2 Fire Protection System per NFPA-12. The calculations indicate that there is a room over-pressurization problem since about 2000# of CO2 is discharged into a 20,000 cu-ft room in about 100 seconds. The code calcs must assume that the heat generated...
I have seen heat pumps used in this type of waste heat application to recover and boost the temperature so the the energy could be used in a practical mechanical application.
