COOLING THE ROOM

This is done using CRAC (Computer Room Air Conditioning) units. Traditionally, cold air is sent into the raised access floor at a slightly higher pressure and exits via perforated tiles in the Cold Corridor. The hot air is evacuated into the hot corridor and reprocessed by the cooling unit.

ROW-BASED COOLING SOLUTIONS

These cooling solutions integrated in the aisle (in or between the cabinets) reduce the complexity of the installation and provide cooling as close as possible to the server.

Particularly suitable for High Density solutions or rooms without raised access floors, row-based cooling solutions optimise the air flow so that it is as short as possible, which results in lower losses.

Exemple: the H2O cooling system. Commonly called a chilled water cooling system, this uses water to exchange thermal energy between the secondary system and the primary outdoor system. When the system is located outdoors, a water/glycol mixture is used as a coolant to prevent freezing.

The system can be designed as a single loop system, avoiding the need for an extra heat exchanger and therefore maximising the free cooling capacity.

Airflow optimization accessories

The right airflow optimization accessories ensure an energy efficient solution! A research carried out by Minkels shows that the use of the correct airflow optimization accessories leads to an enormous reduction in power usage. Based on this research, Minkels has developed accessories which provide concrete products for specific airflow optimization needs.
