For decades, evaporative cooling has been the principal means to regulate the temperature of buildings. And with more than 50% of total building water usage dedicated to heat transfer, there are major opportunities for water savings.
Cooling towers can use several power transmission technologies, including a gear drive, belt drive, direct drive, and electronically commutated (EC) drive. Each has advantages and disadvantages. The proper selection strikes an appropriate balance of initial cost versus operating costs.
Cooling large buildings typically requires the use of air- or water-cooled chillers that produce chilled water, which then cools the air. About 39% of buildings over 100,000 square feet use chilled-water systems employing various refrigeration compressor designs.
How often do you think about your cooling tower or the fill that provides the cooling engine for your process? Unfortunately, if you’re like many plant operators, your cooling tower is but one piece of equipment in your large facility, and its ranking on your priority list is probably lower than many other expensive and more intricate pieces of equipment in your plant.
