“Use less water” sounds like the right place to start a data center heat-rejection discussion.

But the first question is:
What leaving fluid temperature does the system actually need?

Whether a dry cooler can deliver that temperature depends on three things:
• Required leaving fluid temperature
• Outdoor design dry-bulb temperature
• Equipment approach at the required load

A dry cooler can only get the fluid so close to the outdoor dry-bulb temperature. That difference is the approach.
For the applications discussed in the article, a typical dry-cooler approach is around 10°F to 12°F.

If the required fluid temperature is below what ambient conditions plus equipment approach can deliver, dry cooling alone is not enough.

Higher allowable fluid temperatures can open up more options across dry, adiabatic, hybrid, and evaporative systems.

Next time you’re in DC, look closely at the columns in Dulles Airport’s new concourse. They’re part of the air distribution system.

Price DFR diffusers fit into the columns with no visible fasteners, keeping the architecture clean while delivering air where passengers need it.

In the 410,000 square-foot Tier 2 Concourse E, tall ceilings, large windows and heavy passenger traffic made air distribution a challenge.

The team used displacement ventilation to deliver low-velocity air near the floor, focusing cooling on the occupied zone rather than the full height of the concourse.

Getting those diffusers to fit took specialized engineering. The contractor and design team identified Price as the only manufacturer coast-to-coast that could engineer the required three-dimensional diffusers. Price Predict CFD modeling helped verify expected performance.

Havtech’s Steve Clark and Brittany McGurk worked with CMTA, Price and Pro-Air throughout the design process to coordinate the diffuser design, modeling and project requirements.

A high or low classroom CO₂ reading does not tell the entire Indoor Air Quality story.

CO₂ trends can help show:

• Occupancy patterns
• Ventilation demand
• Whether ventilation may be keeping up with the people in the room
• Changes during the school day
• When further investigation may be needed

But CO₂ does not show:

• Particulates
• Volatile organic compounds
• Formaldehyde
• Filtration performance
• Moisture or microbial risk

That distinction is important when school teams are reviewing sensor data or responding to complaints.

CO₂ should prompt better questions. What was the occupancy? What was the outdoor air damper position? What were the humidity and airflow conditions? Were filters and equipment operating as expected?

Treating one reading as proof that IAQ is either good or bad can lead to the wrong conclusion.

Use CO₂ as one part of the investigation, not the entire investigation.

Back in September, Our sales team spent some time with the folks at Baltimore Aircoil Company, and it was a great one!

BAC hosted reps from across the country for a hands-on sales training, including a tour of their manufacturing facility, and a look inside their Research & Development Laboratory. We also met with the BAC teams, leads, and regional sales managers!

Seeing how the equipment is built and tested firsthand gives our team even more to bring to the customers we serve across the Mid-Atlantic. Thank you to the BAC team for hosting!

"The first rule in any organization is no surprises."

That's what prompted a 118,000-sq-ft DC cooperative to add remote monitoring to its HVAC maintenance plan. Good thing they did.

Cool Automation flagged an abnormal compressor condition between scheduled visits, no resident complaints, no comfort issues, nothing obvious onsite. Havtech investigated, found the real issue, and fixed it before it became a $10K-$20K compressor replacement.

See how connected service caught the problem early 👇

Once the rack layout is finalized, some data center cooling decisions become much harder to change.

Before that happens, project teams should be asking:

What rack densities are we designing for now and later?
What happens if a cooling component or power feed is lost?
Where will chilled water, power and controls need to go?
Is there enough room for service and maintenance?
What should be planned now if liquid cooling is added later?

High-density cooling isn’t just an equipment-selection decision. It can affect the layout and supporting infrastructure around the rack.

Here’s what to consider as rack densities increase: https://ow.ly/ETxy50ZTb5W
