VENTILATION SYSTEM DESIGN AND DESIGN BASIS

Ventilation systems are provided to ensure that there is adequate air circulation in areas where refrigeration equipment has been installed. 

 

Machine Room ventilation:

  • Purges ammonia vapor from the machine room in emergency situations

  • Prevents excessive temperature rise in machine room due to equipment generated heat

  • Provides fresh air for the operators

  • Maintains the machine room under negative pressure

  • Provides air movement to all for better ammonia detector response

 

Ventilation calculations are provided to ensure the fan ventilation rate (cfm) meets the temperature control ventilation, continuous ventilation and emergency ventilation requirements for the code or standard the system was designed.

 

Protexus engineers will work with facility personnel to gather the necessary fan and equipment information to evaluate the ventilation to ensure there is sufficient air flow in the Engine Room in the event of an ammonia release.
