To choose the optimal cooling system, the engineer must consider the climate, desired operating cost, water availability, cooling load, and any other potential site-specific objectives and constraints, such as maintenance.

Working to minimize emissions while making the most of the energy used, the YMC² chiller requires less energy consumption, reducing the energy production and the resulting carbon emissions. 

In addition to real-world testing over the past two decades, the TriArmor Corrosion Protection System has also been subjected to a series of rigorous corrosion tests, including an acid test (pH=4), an alkaline test (pH=11), a chloride level test, and a 5% salt spray test. Basins also endured heavy impact testing. 

Featuring a unique direct-drive design, the Vektor-H high-plume laboratory exhaust fan includes an easily accessible motor compartment that is sealed from the contaminated airstream, integral cooling vents, standard motor shaft grounding, and sealed-for-life motor bearings that allow for high-efficiency operation while significantly reducing overall maintenance.

The Criti-Clean Ultra is a ceiling-mounted FFU that can deliver up to 1,200 cfm of HEPA-filtered air into a room. It also offers a low plenum height of 13.7 inches, allowing easy retrofitting into existing ceiling spaces.

Each PQF roll has 60 perforated, disposable sheets providing enough filter replacement for up to one year. The PQF is available in three different lengths — 8, 12, and 16 inches — and is suitable for a variety of applications and air inlet sizes.
 

Improvements currently underway include implementing a series of modernization upgrades to the university’s HVAC, security, and fire and life safety systems with a focus on energy efficiency, resiliency, and sustainability. 

When properly installed and tested in accordance with ASHRAE standard 193, the sturdy, fully insulated galvanized steel cabinet offers less than 2% air leakage. 

With data centers on par with the aviation industry for their contribution to the world’s CO₂ emissions, alternative refrigerants in data center cooling systems have the potential to reduce emissions equivalent to 43.5–50.5 gigatons of carbon dioxide from 2020 to 2050.

Supported and partially funded by the U.S. Department of Energy’s (DOE’s) Office of Energy Efficiency and Renewable Energy (EERE), the project will be led by Caterpillar in collaboration with District Energy St. Paul and the National Renewable Energy Laboratory (NREL).
