Project Background

A cutting-edge data centre in Thailand was determined to upgrade its cooling system efficiency due to concerns over rising energy costs and significant water usage. The initiative aimed at adopting cutting-edge technologies to enhance operational sustainability, ensuring the facility’s extensive cooling needs were met in an environmentally and economically sustainable manner. This strategic was essential for maintaining the high-performance computing environment required for uninterrupted data processing and storage operations.

Challenge

Our client needed to minimize energy consumption and maximize water conservation while ensuring their cooling system remained reliable and effective. Achieving this balance was crucial for uninterrupted operations, requiring precise temperature control to protect critical data infrastructure.

Dpstar Solution

Dpstar successfully implemented a tailored solution across 23 cooling towers, significantly enhancing the operational efficiency, energy savings, and sustainability of the cooling system at a data center. This project stands as another milestone in our ongoing commitment to propel the industry toward more sustainable and efficient cooling practices. Leveraging our deep expertise, Dpstar integrated advanced Variable Speed Drive (VSD) technology and deployed a comprehensive control system to optimize the facility’s cooling operations. Our strategic enhancements included:

  • Advanced VSD Integration: We integrated state-of-the-art Ultra-Low Harmonics Variable Speed Drives tailored to the cooling system’s needs. These drives adjust the operation of pumps and fans to the actual cooling demand, significantly reducing energy consumption while maintaining optimal cooling performance. The VSDs, featuring a built-in optimized DC choke and a low-pass filter, comply with stringent IEEEE519 and G5/4 requirements, ensuring minimal harmonic distortion. Furthermore, the innovative design of the VSDs allows for easy settings cloning and customization of displays, streamlining the management of multiple units.
  • Cooling Tower Side Stream Filtration Skid: To address water conservation, a side stream filtration system was installed beside each cooling tower. This system filters out particles smaller than 0.1 microns, enabling the reuse of cooling tower water. This not only conserves water but also ensures the cooling system operates efficiently without compromising performance.
  • Centralized Control System: A Centralized Programmable Logic Controller (PLC) was deployed to manage the operations of all 23 cooling towers seamlessly. The system’s design incorporates redundancy to guarantee continuous operation. If one CPU fails, the backup CPU immediately takes over, eliminating potential downtime. An intuitive Human Machine Interface (HMI) was suggested to allow for real-time monitoring and adjustments, improving usability and system
