Liquid cooling systems involve circulating a coolant through pipes to absorb heat from servers and other IT equipment, while adiabatic cooling systems use the evaporation of water to cool the air. Both methods can provide highly efficient cooling, especially in high-density data centers. Liquid cooling can reduce energy consumption by up to 50%, while adiabatic cooling can achieve energy savings of up to 90%. These innovative solutions can also reduce water consumption and minimize the risk of overheating.
