Data halls
Modular air-cooled data center
Contained rack modules use in-row cooling and shared outdoor units for air-cooled data halls.
- Cooling approach
- Heat-pipe in-row cooling
- Deployment
- Contained modular rack rows
- Solution planning range
- Up to 25 kW per cabinet
Overview
Connect the module to the cooling plant
Modular rack rows bring power distribution, containment, cooling and monitoring into one coordinated layout. Heat-pipe in-row terminals connect the modules to multi-split outdoor cooling equipment.
Module layout
Coordinate cabinets and containment
Plan the rack rows, power distribution, access aisles and monitoring as one repeatable module.
Indoor terminals
Collect heat beside the racks
Heat-pipe in-row units serve the contained rows and connect to the outdoor plant.
Outdoor cooling
Select the operating modes
The multi-split platform combines refrigerant-pump free cooling, hybrid operation and compressor cooling according to ambient conditions.
Reference configuration
A 300 kW modular configuration
A reference twelve-cabinet module with duty and standby cooling equipment.
In this example
- Per cabinet
- 25 kW
- IT cabinets
- 12
- Total heat load
- 300 kW

| Equipment | Model | Quantity | Duty / standby |
|---|---|---|---|
| Heat-pipe in-row cooling | CLA060H | 6 | 5 + 1 |
| Multi-split outdoor unit | CNQXF300 | 2 | 1 + 1 |
Duty + standby: 2 + 1 means two duty units and one standby unit.
This example is not a fixed bill of materials. Final equipment selection, capacity and redundancy depend on the IT requirements and site operating conditions.
Technology
Inside the system
Integrated containment with room to expand
MetaRow integrates power distribution, cooling, racks, aisles, monitoring and coordinated control. Cooling close to the load and contained airflow support the module's energy performance.
- Expand through multiple modules as the data center grows.
- Prefabricate and pre-commission at the factory for coordinated on-site delivery.
- Use standardized components and an integrated delivery scope to reduce separate site engineering.
| Reference performance | Scope and condition |
|---|---|
| Module PUE as low as 1.2 | A module-level figure associated with integrated containment and cooling close to the heat source. |
| Annual PUE as low as 1.1 | Cold regions, with a multi-split refrigerant system using free cooling. |
Three operating modes, one outdoor unit
The modular outdoor unit combines a variable-frequency compressor and refrigerant pump. Its dual-loop controls automatically switch between three modes and prioritize natural cooling when outdoor conditions allow.
- An independent natural-cooling coil supports operation in low outdoor temperatures.
- Oil-free terminals support long piping routes and large installation height differences; allowable limits require equipment selection.
- The self-developed intelligent controller includes fault self-diagnosis.
- Reference performance: room-temperature fluctuation below ±2 °C with the fully variable-frequency design, and more than 30% outdoor-unit footprint saving through integration.
| Mode | Cooling method |
|---|---|
| Natural cooling | Fully variable-frequency refrigerant-pump operation |
| Hybrid cooling | Variable-frequency refrigerant pump and compressor operating together |
| Compressor cooling | Fully variable-frequency compressor operation |
Five terminal formats for different layouts
Five heat-pipe terminal formats serve different rack layouts and air-distribution paths within the multi-split platform.
