Abstract:
1. A method for controlling energy consumption in a data center, the data center including a cold-hot aisles configuration of IT equipment racks having IT temperature and relative humidity air specifications, the method comprising: segregating hot air from cold air by preventing hot air exhausted from hot aisles from flowing into cold aisles from the hot aisles, the segregating including forming a cold air tunnel in each cold aisle by covering each cold aisle with a roof arrangement; measuring temperature and relative humidity values of the segregated hot air and the segregated cold air; detecting temperature and relative humidity values of outside air; mixing the segregated hot air with a volume of the outside air, the volume of the outside air depending on a result of the measuring and the detecting; measuring temperature and relative humidity values of the mixed air; comparing the temperature and relative humidity values of the mixed air and the temperature and relative humidity values of the segregated cold air to the IT specifications; cooling the mixed air based on a result of the comparison; and providing the cooled mixed air in the cold aisles.
