With a double brood of cicadas forecasted to awaken, now is the time to prepare for how to deal with the mess they will leave behind and the potential damage they can do to equipment.

Chillers are being used as heat pumps, outfitted with heat-recovery systems, used in building electrification projects, and installed in arrays to cool data centers.

A North Carolina-based community college replaces an aging metal-clad cooling tower with a modern HDPE unit, reducing maintenance spending while increasing efficiency.

By splitting the absorption process into two steps, lithium bromide solution concentrations are lower in the system, enabling lower hot water temperatures within the generator, lower hot water flow rates, and the elimination of crystallization risk within the chiller.

In addition to taking up less space, smaller chillers can be more easily installed, weigh less, and pose fewer shipping, rigging, and building-construction challenges. They can also be more energy efficient, with the same or even greater cooling capacity.

Like many universities across America, the University of Cincinnati faced a major infrastructure challenge: having to operate aging central utility plants with older technology.

Manufacturers are offering low-GWP refrigerant alternatives, as EPA is proposing a 700 GWP limit for most new comfort cooling chillers starting in 2025.

The rapid expansion of data centers has raised concerns about their massive energy use and carbon footprint. However, adopting sustainable HVAC solutions can reduce a data center’s environmental impact and energy consumption.
