INVT Enhances Data Center Efficiency at Rajamangala University of Technology Srivijaya in Thailand

1. Project Background

1.1 Project Location: Songkhla, Thailand, on the campus of Rajamangala University of Technology Srivijaya

1.2 Construction Scale: Data center room area of approximately 400 ㎡, with one set of dual-row enclosed cold aisle module, 10 standard server cabinets, and supporting independent power supply & distribution, cooling, fire suppression, and intelligent monitoring systems.

This project adopts modular enclosed cold aisle design + high-efficiency cooling + intelligent operation and maintenance, delivering a next-generation data center tailored for tropical climates—energy-efficient, secure, reliable, and elastically scalable. It provides a solid computing infrastructure for teaching, research, and campus digitalization.

2. Customer Pain Points

2.1 High cooling pressure in Thailand’s hot and humid environment

Optimized cold aisle sealing with high-performance doors and roof panels to minimize cold air loss; improved airflow circulation inside the cold aisle to eliminate local hotspots.

2.2 Limited campus building space requiring efficient room utilization

Modular cold aisle layout with dense cabinet deployment; in-row precision air conditioners integrated between cabinets to maximize space efficiency.

3. Core Design Solutions

3.1 Enclosed Cold Aisle System: Eliminate Air Mixing for High Cooling Efficiency

Cabinet arrangement: face to face layout to form enclosed cold aisles.

Motorized flip roof panels: Interlocked with fire suppression system.

Sealed end doors: Fully enclose the cold aisle to completely prevent mixing of hot and cold air.

3.2 Power Supply & Distribution System: Redundant Design for Stable Power

Adopts grid power + parallel redundant UPS architecture for high-reliability power supply.

Parallel redundant UPS: 2 units of high-frequency online double-conversion UPS, 40 KVA per unit, ensuring seamless switchover during grid outages.

Supports main and branch circuit monitoring of current and voltage for easy operation and troubleshooting.

3.3 Cooling System: High Efficiency & Energy Saving for Hot & Humid Climate

Adapted to Thailand’s year round high temperature and humidity:

2 units of constant temperature and humidity in-row precision air conditioners

Horizontal air supply: Installed between server cabinet rows, close to heat sources for localized cooling, delivering cold air directly to server inlets for maximum cooling efficiency.

Temperature and humidity sensors inside the cold aisle enable real-time monitoring and automatic air volume adjustment to avoid over-cooling or insufficient cooling.

3.4 Intelligent Monitoring System: Full-Link Visualized O&M

Environmental monitoring: Temperature/humidity, smoke, and water leakage sensors deployed in cold aisles, cabinets, and the room; real-time data collection with audible and visual alarms + push notifications for anomalies.

Equipment monitoring: Real-time tracking of UPS, air conditioners, and other devices (current, voltage, temperature).

Physical security: Integrated facial recognition access control and video surveillance for authorized access control and full-time recording.

4. Application Effects & Values

Ensures stable operation of online learning platforms, virtual simulation classrooms, and distance education systems;

Campus management systems migrated to the new data center show significantly improved running speed, data storage security, and reliability, enhancing administrative efficiency;

As one of the first large-scale enclosed cold aisle data centers in Thai universities, it sets a benchmark for digital infrastructure development in universities across Thailand and Southeast Asia, driving regional education computing upgrading and green data center development.
