What is the temperature limit rise allowed for ventilation systems in NH3 mechanical rooms?

The specified temperature limit rise allowed for ventilation systems in ammonia (NH3) mechanical rooms is set at 18 degrees Fahrenheit. This regulation is important because ammonia systems can operate under pressure and high temperatures, and the ventilation must ensure that the temperature within the mechanical room remains within safe limits. Maintaining this 18-degree rise helps prevent any potential safety hazards and ensures that the ammonia remains within compliant operation parameters, protecting both equipment and personnel.

In ammonia refrigeration systems, controlling temperature is critical for the longevity of the equipment and to mitigate risks associated with ammonia leaks or compromised conditions that could affect the safety and efficiency of the system. By adhering to this temperature limit, operators can maintain effective cooling and ventilation, crucial in spaces where ammonia is stored or used.
