Air‑side free cooling faces hurdles in hot, humid data centers

Data centers consume large amounts of energy for cooling. Air‑side free cooling uses outside air to reduce reliance on chillers. In hot, humid climates, the ambient air often lacks sufficient temperature or dryness. This limits the effectiveness of free‑cooling systems. Operators must balance energy savings with equipment reliability. Solutions such as dehumidification or hybrid approaches are being explored. The challenge impacts the overall sustainability goals of the industry. Experts say careful design is essential for successful implementation.
