New A/C System for Datacenter Reduces Power Consumption by 25%

Obayashi Corp., a major Japanese construction company, announced on April 19, 2012, that it has verified the energy saving effects of its newly developed air conditioning system for data centers. The new system supplies cool air from the ceiling and reduces air-conditioning power consumption by 25 percent.

Traditional air conditioning systems for data centers generally blow cool supply air from grills on the floor, which, in turn, often causes a short circuit of hot air from servers into cold aisles to create hot spots. Because of this airflow problem, cooling datacenters had challenges in lower air-conditioning efficiency and greater air supply, which increases power consumption.

The new air conditioning system blows supply air from the ceiling, in which cool air is kept between server racks and on the floor within a cold aisle and supplied effectively to the servers. This assures efficient airflow which, according to the company, reduces A/C energy consumption by 25% when compared to conventional systems.
