Efficient Cooling Strategies for Modern Data Centres

Ajay Kumar Sharma

Abstract: Modern data centres support critical digital infrastructure and operate continuously, resulting in significant heat generation from IT and power equipment. Cooling systems therefore, play a vital role in maintaining equipment reliability, availability, and energy efficiency. This paper presents a technical review of data centre cooling strategies, including conventional air-based systems, airflow management techniques, containment solutions, free cooling technologies, and emerging liquid cooling methods. The impact of these approaches on energy consumption and operational performance is discussed with reference to industry standards such as ASHRAE. The study highlights how effective cooling design and optimization can significantly reduce power usage effectiveness (PUE) while supporting increasing rack power densities.
