In-row cooler

Precision in-row cooling controlled and integrated via ColdLogik's award winning Management and Room Management Systems

In-row cooling technology is a type of air conditioning system commonly used for data centre cooling in which the cooling unit is placed between the server cabinets in a row to offer cool air to the server equipments more effectively.  In-row cooling systems use a horizontal airflow pattern utilising hot aisle/cold aisle configurations and they only occupy one-half rack of row space without any additional side clearance space.

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.

 

ColdLogik Management System 'CMS'

The ColdLogik Management System 'CMS' lies at the heart of the ColdLogik CL80 and CL20 solutions. The room ambient temperature is controlled locally at cabinet level by the CMS. It automatically adjusts the fan speed, water flow rate and, if necessary, the output water temperature from the cooling medium – the result is a consistent delivery of cooled air into the data centre, with no operator intervention.  The whole process can also be overseen and controlled at individual cabinet level, room level and remotely via any of the industry standard communication protocols. The CMS is situated inside of the cabinet. It ensures all variants of the ColdLogik system operate on a ‘sensible cooling’ principle – ‘water above dew point’ – and the system remaining free of condensation.
