What Does In-Row Cooling Mean?

In-row cooling technology is a type of air conditioning system commonly used in data centers in which the cooling unit is placed between the server cabinets in a row for offering cool air to the server equipment more effectively.

Techopedia Explains In-Row Cooling

The in-row cooling unit draws warm exhaust air directly from the hot aisle, cools it and distributes it to the cold aisle. This ensures that inlet temperatures are steady for precise operation. Coupling the air conditioning with the heat source produces an efficient direct return air path; this is called “close coupled cooling,” which also lowers the fan energy required. In-row cooling also prevents the mixing of hot and cold air, thus increasing efficiency.
