To most people, HVAC (Heating, Ventilation and Air Conditioning) units are useful for two things: keep us warm in the winter months, and cool us down during the summer. On the other hand, as experts in this field will know oh too well, there is plenty more involved in maintaining a comfortable and more importantly safe working environment.
In order to ensure problems don’t persist, regular measurement HVAC systems with refrigeration gauges is of course important. But the indoor climate within a building is not only affected by the temperature and humidity, but also the indoor air quality.
In short IAQ is judged based on the number of contaminants within the atmosphere of a room or building. Various gases are bound to be present, sometimes in very small (and therefore harmless) amounts. Examples of this include ozone and carbon dioxide. Whilst when these gases are present in small amounts they are not dangerous, this can change if the building is subject to lacklustre ventilation.
The Environmental Protection Agency on their website state that “Indoor Air Quality (IAQ) refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants.” They go on to say “Understanding and controlling common pollutants indoors can help reduce your risk of indoor health concerns.”
Immediate effects of indoor air pollution often resemble those from a common cold or illness, making a potential issue even more difficult to detect. There are a number of illnesses that result from contaminated indoor air. Some of the more minor effects include irritated eyes, nose or skin as well as an increased likelihood of irritation of the eyes, coughing, headaches, dizziness, fatigue and nausea.
In extreme cases, those who spend a great deal of time in an incorrectly monitored environment are at risk of long-term illnesses for example heart disease, respiratory problems, or even cancer.
The Environmental Protection Agency conclude that “It is important to pay attention to the time and place symptoms occur. If the symptoms fade or go away when a person is away from the area, for example, an effort should be made to identify indoor air sources that may be possible causes.”
By measuring a number of parameters you will get a true picture of the indoor air quality
