In HVAC systems, there are many different parameters that are commonly measured for system performance or building comfort. Some of the most commonly measured HVAC system parameters are temperature, air velocity, humidity and static pressure. Of those parameters, static pressure is extremely important in terms of system performance. Static pressure indicates how hard the HVAC system has to work to move air through the building or how much resistance to flow exists. The higher the static pressure, the harder the system has to work to move air through the building. Continue reading “Static Pressure in HVAC Systems”

Dwyer Instruments, Inc. was recognized for excellence in product design in the 16th annual Dealer Design Awards Program sponsored by The Air Conditioning Heating & Refrigeration News Magazine (The ACHR News). An independent panel of contractors acted as judges in the contest that had 79 entries. The company’s Hydronic Application Software was the Silver Award Winner in the Contractor Services & Software product category. The ACHR News is the leading trade magazine in the heating, ventilating, air conditioning, and refrigeration industries. 
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.
