One particular research avenue shows that dynamically changing fan speeds could give instant seasonal energy efficiency improvements in reversible, modular chiller units.

As with any refrigeration system, controlling the flow of refrigerant is vital in making a cold room operate properly. Two of the most common types of refrigerant control valves are thermostatic expansion valves and solenoid valves.

As part of a recent renovation at Flagler College in St. Augustine, Florida, a new air conditioning chiller was installed in Kenan Hall, the main academic building of the campus.

When the time comes to replace a cooling tower, all too often the recommendation is to source an identical replacement; however, cooling tower technology is evolving, and some building owners are reaping the rewards by researching the benefits of the newest options.

Pharmaceutical manufacturing facilities are energy intensive, and the HVAC system — the chilled water plant, the steam and hot water plant, and air distribution — typically consumes a full 65 percent of the energy used, according to research by Lawrence Berkeley National Laboratory.

Most engineers focus on improving energy efficiency to reduce energy consumption.

In April of 2011, the University of Utah broke ground on a renovation to consolidate multiple production centers into a central multi-tier data center in support of their diverse program mix, which includes the university’s Center for High-Performance Computing (CHPC).

NYC Health + Hospitals, The LiRo Group, and the New York Power Authority (NYPA) have completed the installation of an antimicrobial cooling tower in New York City.
