The Importance of Proper Ventilation in Learning

Ventilation is an important aspect of HVAC (heating, ventilation and air conditioning) systems as it helps a room in so many ways. It provides comfort by improving the quality of air around the room. It also controls odors and certain gases so that they don’t stay within the room for too long. If this is a problem with your house as well, you must try the exhaust fans to control it. You can contact them anytime for consultation.

That said, proper ventilation is especially important within schools as they provide enough breathing room and limit the spread of respiratory diseases, even if it’s as simple as ceiling fans.

Facilities follow building codes that ensure that there is enough ventilation around. For example, schools must have auditoriums or functions that are usable for any occasion. Gymnasiums can also work and they are quite open and spacious, giving enough air to the people who use it.

Ventilation Requirements

Under international standards, rooms must have a maximum occupancy rate that matches the space it has to at least allow people to breathe in. This is usually done by having an air balancing contractor measure the flow of air that comes from the outside and adjust the way the air dampers are set up in a building to get the minimum rate of air supply from outside.

This can be challenging, as changes to damper positions can also drastically affect the rate of outside airflow. This also has an effect on the energy being used throughout the building.

One method of measuring ventilation is to look at the difference between the returning air and supply air stations. There were also products made to control the flow of outside air that would come into the building.

Alternatively, the fan-injection method can be used, wherein a fan and measuring station controls the minimum outside air brought into the building by the HVAC system. One risk is that the system can use up quite a bit more energy than usual. Another means of handling this is by using damper assemblies to maintain the minimum ventilation needed.

Outside Air Management

To measure outside air, sensors can be installed throughout the air damper arrangement. The sensors are made of a flow-measuring station set within a low-leakage damper that has a set of airfoil blades. The blades will contain the air pressure-sensing ports. These ports are at two sides: one to sense total pressure while the other senses static pressure.

This setup will result in the onboard differential pressure transducer adjusting the position of the dampers to maintain the needed minimum airflow.

Controlling airflow is just the first step. According to ANSI/AMCA Standard 610-95, uniform tests have to be conducted to measure the devices’ ability to perform and accurately gauge airflow. Professionals working on the HVAC system should know about code requirements and ventilation control within educational facilities.

Being properly equipped can ensure the prevention of Sick Building Syndrome, a set of respiratory problems and other ailments characterized by headaches and high stress levels. Under ASHRAE Standard 62, a majority of occupants must not suffer from discomfort due to air quality or are at risk of being exposed to varying conditions in the air.
