What is the discharge temperature of a CO2 bottle?

The discharge temperature of a CO2 bottle is approximately -110 degrees Fahrenheit. This temperature is a result of the physical properties of carbon dioxide as it transitions from a liquid state to a gaseous state when released from the pressurized bottle. When CO2 is stored in the bottle, it exists in a liquid state under pressure. Upon release, it expands rapidly, causing a drop in temperature due to the Joule-Thomson effect, which occurs when a gas expands without doing external work and without heat exchange.

Understanding that this discharge temperature is significantly below zero is important in damage control contexts, especially when considering the potential hazards of freezing or frostbite in handling CO2 systems. Recognizing the correct discharge temperature is crucial for safety protocols and effective response measures in emergency situations involving CO2 fire suppression systems.
