Bulletin No. 111. Guidelines for Ammonia Machinery Room Ventilation. IIAR Ammonia Refrigeration Library, (1991, October). Major differences can be found between codes when determining ventilation requirements for ammonia machinery rooms. This bulletin cuts through the jargon and provides a practical ventilation design criteria that will satisfy existing code requirements and improve machinery room safety.
