All mechanical rooms must be mechanically ventilated to maintain room space conditions as indicated in ASHRAE 62, ASHRAE 15, and Table 5-1 of this chapter. mechanical ventilation, air conditioning and dehumidifying. Mechanical ventilation requirements vary significantly depending on the type of occupancy, but the end goal is always to ensure acceptable levels of indoor air quality. The illustration above demonstrates the use of a ceiling exhaust fan mounted in the rest room exhausting the stale air. When it comes to ammonia refrigeration machine rooms, ventilation updates can often be overlooked..
