In this episode of Did You Know? The ESCO HVAC Podcast host Clifton Beck sits down with Ken Duncan, Lead Data Center Application Consultant at Belimo, to explore the evolving role of HVAC in data centers, AI servers, and Bitcoin mining facilities.

Ken shares thoughts about the rapid shift from air cooling to liquid cooling, the impact of high-density server racks, and how intelligent control valves and automation are optimizing efficiency in mission-critical facilities.

If you're an HVAC professional, educator, or technician looking to stay ahead of industry changes, this episode provides valuable meaning into the future of HVAC in digital infrastructure.

Key Takeaways:

• Cooling the Digital World – Data centers, Bitcoin mining, and AI servers generate extreme heat, requiring innovative cooling solutions.
• Shift to Liquid Cooling – Traditional air cooling is being replaced by water and immersion-based cooling to handle rising heat loads.
• The Role of Smart Valves – Intelligent control valves optimize cooling efficiency, adapt to changing server demands, and reduce energy costs.
• Water & Heat Recovery – Data centers are transitioning to closed-loop water systems to reduce evaporation loss and improve efficiency.

Noteworthy Quotes:

• "Air cooling simply can't keep up, liquid cooling is the future of data centers." – Ken Duncan
• "A single high-density server rack generates the same heat as 15 barbecue grills running at full blast." – Ken Duncan
• "Data centers aren’t just consuming energy; heat recovery strategies are now turning waste heat into usable energy." – Ken Duncan
• "AI is already optimizing HVAC performance from chiller plants to variable-speed pumps." – Ken Duncan
