Why Are In-row Air Conditioning Systems Needed?

Traditional data center air conditioners are typically placed around the perimeter of the server room or under the floor, requiring cool air to travel a long distance to reach the front of the server racks. When rack power density increases (e.g., exceeding 5kW), this "room-level" cooling easily becomes insufficient, leading to airflow mixing and localized hotspots.

In-row air conditioning, a form of "close-coupled cooling," significantly shortens the cool air path, precisely addressing localized heat dissipation issues. Its main advantages are as follows:

Handling high-density heat dissipation: Single rack power density can range from 5kW to over 30kW, making it particularly suitable for AI and high-performance computing scenarios.

Significant energy savings: Short fan airflow paths and low power consumption enable "on-demand cooling," significantly reducing the PUE value.

Flexible deployment: It can employ various solutions such as air cooling, water cooling, and direct expansion, supports hot and cold aisle closures, and can be installed without raised floors.
