It seems our industry is becoming “commoditized,” and we are unintentional accomplices. We’re too comfortable swapping equipment and installing silver bullets while moving away from providing true comfort.
The air duct calculator, or “ductulator,” is a commonly used tool for designing and installing duct systems. Unfortunately, many designers and technicians receive limited instructions on its correct use.
Building codes are continuously growing stricter, focusing greatly on efficiency. A factor that plays a large role in meeting these building codes is proper mechanical ventilation and, in particular, its ability to create comfortable living conditions.
Daikin demonstrated its expertise in “Air Intelligence” through several new technologies at the 2018 AHR Expo, including its VRV T-Series Water Cooled Condensing Unit, Daikin VRV AURORA™ Series, PreciseLine™ Large Capacity Blower Coil, and more.
There’s a lot of attention on IAQ in the HVAC industry, so Friedrich Air Conditioning Co. decided to command some of that attention to its booth at the AHR Expo, where the company unveiled its new packaged terminal air conditioner (PTAC) unit
The war on germs is on, and RGF Environmental Group Inc. is dominating the fight. The company rolled into the 2018 AHR Expo alongside the Germinator — a large, army-like vehicle, equipped with a giant REME HALO® mounted to the roof, which makes it capable of eliminating pollutants everywhere it goes.
The Uponor booth was organized in such a way that its design was able to display the company’s message and brand of being a complete solutions provider.
Research from the U.S. Department of Energy (DOE) has consistently shown about 30-40 percent of the air traveling through ductwork leaks, and if air is being pulled from somewhere, like a dirty crawlspace, it is going to effect IAQ.
To understand the operation of combustion air openings, it’s a good idea to review some airflow basics. For airflow to move through a duct, there must be a pressure difference across it created by an external source. Traditional installations depend on natural forces to create this pressure difference.
