FOR COOLING TN BOILER FOR HEAT ADD AND OR CHILLER FOR COOLING The Importance of Air Quality Indoor air quality IAO should be considered a top priority in the school environment School institutes contain a diverse day of activities that have a potential for air impurity sources including cafeterias art and science classrooms vocational education areas pools and locker rooms Proper ventilation and filtration of these spaces can pose some challenges Occupant density in classrooms is much higher than that found in office or retail spaces The amount of outdoor air required to ventilate a classroom is based predominantly on the number of students expected to occupy the space Students also move in large groups frequently throughout the building resulting in widely varied thermal loads within the zones To compound the situation a classroom mechanical system is typically run for 9 months of the year and vacated for 3 months either by turning up or off the HVAC system To increase the IAQ challenge even more building construction techniques that help reduce energy costs also tightly seal the school This can lead to uncirculated unfiltered air Ventilation Ventilation is an important factor in the maintenance of healthy air In a poor ventilated school building fumes and vapors are not properly exhausted allowing particles to develop A healthier building is a building where the
