How To Measure Air Quality

Like all things, we can measure air quality scientifically. We can get a number that says just how gross the air in your facility is. Not only that, but we can figure out what particular type of problem your air has. There’s more to air quality than just saying it’s good or bad. The Troublemakers There are three commonly examined areas for air quality. We have different ways to detect and measure each of them, but these are typically available all in one tool or device. Particulate Matter There are tiny particles in the air, often harmful chemicals we don’t notice individually. Think of things like the exhaust from a car. That exhaust is made of billions of tiny particles of burned fuel and even metal shavings from the engine. These can have negative health effects. Particulates from cars could play a role in Alzheimers Disease. These can detect bacteria, viruses, and mold as well. Sensors for these are rated in their measuring sizes, 2.5 microns and below, 10 microns and below, etc. Your hair is about 40-70 microns thick, for comparison. Volatile Organic Compounds The rule of thumb is that a VOC is something you smell and notice. That’s not always the case, but it’s a good guiding post. These chemicals are highly reactive, dangerously so. Examples of these are things like cleaning chemicals, gasoline, and paint. They’re things you should try not to breathe in. Carbon Dioxide This […]

Blizzard Testing Your HVAC System

Can you tell it’s winter yet? Is it safe to come out yet? Here in the North East, Mother Nature has just finished her first major storm of the season. We can confirm that no one at Procure is interested in living in the far, Arctic North after experiencing days-straight of subzero temperatures. We were within spitting distance of water being able to freeze before it hits the ground. Along the way, we also got to push our heating systems to their edges and see where we really should’ve built things differently. Edge Case Testing During normal operation, it’s doubtful you’ll ever see something out of place in a well designed heating system. If you engineered a system for an average winter, then chances are you can turn your home or office any temperature you like during average weather. It can be ten degrees outside, but a sweltering 92 inside. When nature throws you a curve ball you get to see where the weaknesses are in your heating system. More extreme weather, is more stress on the system. More stress is going to show you what parts can’t keep up. This breaks down to a problem of numbers. The sum-total of heat you can put in the air is XX. Your building loses heat to the air at a rate of YY. Severe winds increase this rate by ZZ. In order to stay warm XX needs to be greater than […]
