3.3.1 System Description
The cooling system uses chilled water in-row precision air conditioners and an aisle
containment for cooling. The in-row precision air conditioners and equipment cabinets form
an aisle containment as shown in Figure 3-39 to separate hot air from cold air.
With the rapid development of data centers, power consumption of core equipment in a
traditional equipment room has risen from 3-5 kW per cabinet to 10 kW per cabinet. This
brings challenges of heat dissipation, energy saving, and environment protection to the
traditional air cooling system.
The traditional air cooling system cannot meet the requirements of new-generation data
centers. The new in-row air conditioners can solve heat dissipation problems caused by
high-density deployment to lower the data center cooling power consumption and the PUE
value. They can be installed beside cabinets thanks to good compatibility with standard
cabinets.
The in-row air conditioners provide a high-heat-flux cooling solution that applies to
high-density data centers or overheated areas in common data centers. High-heat-flux cooling
solutions are classified into water-based or non-water-based solutions depending on the
cooling medium. The NetCol5000-C in-row air conditioner is a water-based solution.
In-row air conditioners are close to heat sources, which shortens the air supply distance,
reduces airflow pressure loss and cold air loss, and maximizes the use of cooling capacity.
