HVAC (heating , Ventilation and Air conditioning) BLOG

The AI revolution is reshaping data center design — and nowhere is that more evident than in cooling. Modern AI workloads demand unprecedented compute power, pushing server racks into the 50–100 kW per rack range or higher. Traditional air-cooling techniques simply can’t keep up with the explosive thermal loads these systems generate, forcing engineers and operators to rethink how heat is managed at scale. ( Business Wire ) Conventional air cooling — involving raised floors, CRAC units, and hot/cold aisle containment — once handled modest loads of 5–15 kW/rack. But AI clusters packed with GPUs and custom accelerators produce far more heat. Air becomes inefficient as speeds reach limits and energy costs climb, making it increasingly unsustainable for racks beyond 50 kW. ( datacenters.com ) Liquid Cooling Takes the Lead To meet these demands, data centers are rapidly adopting advanced liquid-based cooling strategies that can handle intense heat densities with greater energy efficiency: ...

 Data centers are the backbone of our digital world, housing servers that power everything from streaming services to cloud computing. However, the energy-intensive nature of these facilities poses a unique challenge: keeping equipment cool to maintain performance and prevent downtime. Let’s explore key cooling solutions that ensure optimal efficiency and sustainability in data centers. 1. Traditional Air-Based Cooling Systems Air-based cooling remains a cornerstone in many data centers due to its simplicity and effectiveness. Key systems include: CRAC Units (Computer Room Air Conditioning) : Circulate cool air to maintain a steady temperature. Raised Floors and Hot/Cold Aisle Containment : Direct airflow to ensure efficient cooling and minimize mixing of hot and cold air. However, these systems can become energy-intensive, especially in high-density data centers. 2. Liquid Cooling Solutions Liquid cooling is gaining traction as servers generate more heat. It involves the use of l...
