10 HVAC Setbacks to Avoid | Air Heat Exchangers

When the researchers compared their findings to data from living animals, they discovered that the dinosaurs’ noses were just as efficient at warming and cooling respired air. "This was a case of nature finding a different solution to the same problem," said Bourke.

Sutherland believes an ammonia/CO2 system is more efficient than a CO2 system, though CO2 produces high-grade heat for reclaim while NH3/CO2 generates low-grade heat.

With all the above information in mind, the question on the table is, how can you, as a facility manager, be assured that the fire alarm systems in your building(s): 1) are fully compliant with current fire code, and 2) what steps can you take to ensure that these systems continue to operate as designed in the foreseeable future?

"The biggest source of pollutants — outside of a wood stove — is cooking. Any time you’re cooking, you need to have a range hood [running]."

Second Wind Air Purifier products will remain available through existing sales channels and contacts. As phone numbers and sales staff will remain in place, Second Wind Air Purifier customers will experience minimal change or disruption.

Paul Denham, Southern Air’s president, credits the firm’s 14% revenue increase from 2016 to 2017 to the company’s design-build capabilities on projects such the the Hotel Madison in Harrisonburg, Va., and the Devils Backbone Brewing Co. in Lexington, Va. “We’ve been a design contractor probably since our existence,” he says. “We’re comfortable challenging design issues, whereas a lot of other [specialty] firms that don’t have the internal design experience are afraid to challenge a mechanical or electrical engineer and say, ‘Well, here’s another way to do it that may be less expensive.’”

"A decade ago, my colleague Ryan Ridgely and I published the discovery that ankylosaurs had insanely long nasal passages coiled up in their snouts," said study co-author Lawrence Witmer, professor at the Ohio University Heritage College of Osteopathic Medicine. "These convoluted airways looked like a kid’s ‘crazy-straw!’ It was completely unexpected and cried out for explanation. I was thrilled when Jason took up the problem as part of his doctoral research in our lab."

Rectangular or square and smaller than a pinhead at between one and four millimeters tall, these components are not easily seen. But however unremarkable MEMS sensors may seem at first glance, these mighty mites are the stars and polymaths of the connected world. “MEMS sensors measure the world and teach electronic systems how to see, feel, and smell. They turn a simple cell phone into a smartphone that takes sharp pictures and navigates on the street and over multiple stories in buildings,” Fabrowsky says. With the benefit of MEMS sensors, drones glide smoothly and can be controlled precisely even in winds. Installed in fitness trackers and smart watches, they count steps, stairs, and calories. These diminutive sensors’ fine-tuned receptors measure temperature, air pressure, humidity, and even air quality. They allow indoor air-conditioning and ventilation systems to be controlled more efficiently and, when office meetings drag on, they can trigger smartphone reminders that it is time for some fresh air. The first MEMS sensors developed nearly 25 years ago were not meant for smart-home technology or consumer electronics; they were destined for cars. These perceptive miniatures furnish data to the control units about when the car brakes or accelerates, as well as about the direction the car is traveling. The ESP electronic stability program uses this information to keep cars, trucks, and even motorcycles safely on track and in their lanes. Moreover, the GPS never loses sight of its destination, even if its signal is temporarily interrupted.
