Expansion of the computer room’s capacity from 33 kWTI to 80 kWTI. For this project, a new electrical distribution (2N) was installed to supply cabinets, as well as two uninterruptible power supply units of 80 kW/100 kVA each. Existing cooling units were replaced in order to increase reliability, efficiency, and cooling capacity. New cooling equipment as well as their sequence of operation were chosen to meet the new ASHRAE standards. The equipment is controlled to maintain optimum operating conditions of temperature and humidity in the cold corridors of the computer room.
