I’m not in front of the computer, so I can’t check if my answer is right but I’ve found the following information.

Hot AISLE containment system combined with aisle cool units.



SAIFOR recommends the use of hot aisle containment solutions for various reasons:

When the hot air becomes concentrated, air ΔT is increased and the cooling units are kept in the best operating zone.

The cold air expelled into the cold aisles can be used to reduce the overall temperature of the room.

The room itself acts as a “cold-air containment”.

I’ll carrying on looking when I get home.

Does the cooling system have anything to do with datacenters?

In-row cooling systems work within a row of standard server racks. The units are standard rack height, making them easy to match with the row and couple tightly to the IT equipment to ensure efficient cooling. Systems from APC by Schneider Electric, Liebert by Emerson Network Power, Rittal and others are engineered to take up the smallest footprint and offer high-density cooling. Ducting and baffles ensure that the cooling air gets where it needs to go.

Tiene una tipología basada en el confinamiento de los pasillos calientes, en forma de tres cubos, y la refrigeración es mediante aire externo (free-cooling) y extracción del aire caliente, que además es aprovechado como apoyo a la calefacción de las oficinas. Ello le permite obtener una gran eficiencia enegética al aprovechar mejor el clima de Santander y evitar casi en su totalidad el uso de aire acondicionado.

Hot aisle/cold aisle
The idea of hot aisle/cold aisle seems simple, but it’s a little tricky. Ideally, cool air passes in front of parallel rows of racks, being drawn in toward equipment, and hot air comes out the back of the rack or overhead and is exhausted out of the room, producing constant air circulation.

Most major server manufacturers recommend that cabinet doors used in hot aisle/cold aisle installations have at least 63% open area for airflow. You can achieve this by either removing cabinet doors altogether or by buying cabinets that have mesh doors. Also, cabinets with side panels keep the air within each cabinet from mixing with hot air from an adjacent cabinet.

I've seen 'cabinets', 'enclosures' and 'units' but I'm not sure which term is the best.
