Chilled Water In-Row Precision Air Conditioner is a close-coupled cooling unit installed between server rack rows. It adopts low-temperature chilled water supplied by central building chillers as heat exchange medium for cooling. The indoor unit is equipped with water cooling heat exchanger, which absorbs heat from hot rack air via chilled water. The warmed return water flows back to central chillers for unified heat dissipation and cooling to realize continuous temperature control.
This unit requires no outdoor refrigerant copper pipes or DX condensers. It is perfectly matched for large high-density data centers with central chilled water systems, featuring large cooling capacity, low operation noise and outstanding energy efficiency. It has become the mainstream cooling solution for large-scale cloud computing and AI intelligent computing centers.
Core Product Advantages
● Huge Cooling Capacity for Ultra-High-Density Computing
Higher maximum cooling capacity per unit supports GPU server clusters with 10kW~30kW high heat load per rack. It rapidly dissipates concentrated rack heat and eliminates hotspots to meet dense deployment demands of large intelligent computing centers.
● Low Noise & Stable Operation for Better Room Environment
No noise generated by outdoor air-cooled fans; indoor units operate with low vibration and low noise, avoiding superimposed noise interference even in densely arranged multi-story large data centers.
● Excellent Overall Energy Efficiency to Cut PUE
Matched with cooling towers and free cooling heat exchangers of central chilled water stations, it can run under free cooling mode for most of the year to reduce chiller startup frequency. The overall data center PUE can be steadily controlled below 1.2, delivering remarkable long-term electricity savings.
● High Safety Level with No Refrigerant Pipes Indoors
Only chilled water pipelines are laid inside the server room without high-pressure refrigerant copper tubes, eliminating risks of refrigerant leakage and flammable hazards, complying with high-standard fire protection and safety codes for large data centers.
● Convenient Cluster Control & Capacity Expansion
Multiple chilled water in-row units can run synchronously by connecting to the same chilled water pipeline. Intelligent load balancing via DCIM group control is supported. Extra units can be added in batches during computing expansion, and N+1/N+2 redundancy ensures non-stop cooling.
Application Scenarios
● Large-scale public and private cloud data centers
● AI intelligent computing centers, GPU supercomputing and rendering cluster rooms
● Multi-story park-style core Internet server rooms
● Large financial, government and enterprise equipment rooms equipped with central chilled water systems
