Over the past weeks, we have noticed that the dining hall gets super stuffy, and sometimes it’s difficult to breathe in there.
We usually open the windows to help with the indoor air quality.
Even the cleaners had noticed that the tables would get very dusty. Since it is summer, the tables get very dusty. From our science and technology studies, we knew a little about heat and AC products, and dusty surfaces and low air quality was an indication of dirty air filters. When the technicians arrived, our science teacher gave us a chance to shadow them so we could learn a thing or two about air purification systems. The technicians started by inspecting the ductwork that was covered in grease from all the cooking. They redid duct sealing on some parts of the vents. Afterward, they started with the duct cleaning process which involved cleaning and replacing the washable filters to improve the quality of air. The technicians allowed one of us to call the local business to deliver a new dozen of filters for future use. With the warmth from the heat pump, the filters were able to dry and we tested their efficiency. The air purifier had stopped making weird noises once the air ducts were cleaned. The technicians even illustrated how to use the new digital thermostat which most of us knew how to use because of the HVAC system in our homes. By the end of the day, we had a well-functioning air quality system in the dining hall. We had dinner that evening in a well-ventilated room with high-quality indoor comfort. We also learned a lot about how to operate HVAC systems.
