Variable frequency drives (VFDs), also known as variable speed drives (VSDs), are used to modulate the speed of motors in various applications, from hydronic water pumping to VAV fan units to vacuum ...

The Automatic Tube Cleaning System (ATCS) provides energy-saving, on-line condenser tube cleaning for water-cooled chiller applications. The system periodically injects sponge balls into the condenser ...

This may not sound like much, but such improvement can be very valuable. In this first part of a two-part series, we will examine basic ideas behind the importance of condenser heat transfer, and in ...

Air-cooled condenser (ACC) systems have emerged as a viable alternative to traditional water-cooled solutions in power plants, particularly in regions where water scarcity or environmental concerns ...

Summer peaks are still with us, and every unit on your system must be prepared to operate at a moment’s notice. Spot power prices are so high that you expect phone calls asking for a few more ...

Access to clean water is a huge issue across the globe. Even in areas with water resources, a lack of infrastructure or reliable energy means purifying that water is sometimes extremely difficult.

Building-scale heating, ventilation and air-conditioning systems tend not to get much attention unless they’re malfunctioning. But in these types of systems — which account for roughly 10 percent of ...

The University of Miami Central Energy Plant represents one of the largest facilities of its kind in South Florida. Among its features: three high-efficiency, variable-flow 3900-ton chillers piped in ...

Microbial inhibition, as part of a robust cooling water treatment program, presents a special challenge because of the variability in makeup water sources, plant processes, and discharge permits.
