Low-Voltage Electrical Systems Drive Data Centre Sustainability

Traditional air conditioning systems can be expensive, energy-intensive, and environmentally unfriendly, making them an unsustainable option for many modern data centres. In response, innovators are turning to low-voltage electrical systems to keep giant new facilities cool. One such solution is the use of chilled water systems, which use a refrigerant to chill water that is then pumped through a network of pipes to dissipate heat from equipment. This approach can be more energy-efficient than traditional air conditioning systems, as it utilizes the cooling properties of water rather than relying on electricity. Another emerging technology is the use of electroactive polymers (EAPs), which are materials that change shape in response to an electric field. When applied to a surface, EAPs can absorb and dissipate heat, making them a promising material for cooling data centre equipment. Researchers have already demonstrated the effectiveness of EAP-based systems in reducing temperatures by up to 20°C. Some companies are also exploring the use of advanced materials such as phase-change materials (PCMs) to cool data centres. PCMs can absorb and release heat over time, providing a stable and consistent cooling effect. By incorporating these materials into data centre design, operators can reduce their reliance on air conditioning systems and lower their energy bills. As the demand for data storage continues to grow, it’s likely that innovative cooling solutions will play an increasingly important role in keeping giant facilities cool and sustainable.
