Chillers and Towers

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.

Despite their similar exterior appearance, cooling towers and closed-circuit coolers are very different pieces of equipment with distinct advantages and limitations. This is especially true when determining which option is best suited for a specific cooling application.

Michael Daly, chief technology officer, ECM Technologies, offers insights into the HVAC commercial market.

Chillers use the principles of thermodynamics to remove heat from a conditioned space. But “chiller” is a broad term that encompasses system configurations, refrigeration technologies, and methods of rejecting captured heat. Experts take a closer look.

The city of Phoenix sought an energy-efficient HVAC solution that would restore Phoenix Art Museum’s lost efficiency and improve the indoor climate for the museum’s specialized environment while also contributing to the city’s energy conservation goals.
