Hot-wire anemometers are often used in a hospital environment to measure and maintain room pressurization/de-pressurization. These applications require a positive pressure in operating rooms where bacteria cannot be allowed to enter, or a negative pressure in a quarantine environment to ensure that all bacteria will stay within the room. Continue reading “Hospitals: The Hot-Wired Anemometers That Keep Them Running Properly”
Many people think that we get cold and flu viruses more often in the winter due to the cold temperatures outside; however, this can actually be attributed to the fact that we are inside more, thus being exposed to higher concentrations of pollutants. Poor indoor air quality can cause what has come to be known as sick building syndrome.
Air balancing is the process of testing and adjusting an HVAC system to deliver the correct amount of air to each room of a building. The most common tool used in air balancing is an air flow hood, which measures the volume of air coming out of a diffuser in order to find areas of the system where the flow is limited. The 2016 Dealer Design Award-winning SMART Air Hood® Balancing Instrument, Series SAH, was designed by your HVAC market leader to be the most accurate and easy to operate air flow hood on the market. But what exactly gives the Series SAH an advantage against comparable products? Continue reading “8 Reasons to Buy the SMART Air Hood® Balancing Instrument”
I often get asked, how should one simplify the hydronic balancing process? Since system blueprints will specify exactly where to set the balancing valves on the hydronic system to achieve proportional flow, it may seem simple enough for an installing contractor to determine the pressure drop through each circuit; however, hydronic systems are rarely installed exactly as designed. Continue reading “Work Smarter, Not Harder. Hydronic Balancing Simplified.”
