Outdoor temperature and Cooling power Relation
Datacenters use cooling units to take away hot air exhausted by IT devices. Cooling energy depends on IT energy in the datacenter. But, we know with observation that, outdoor temperature has an effect on cooling load too. If weather is hot, cooling demand ascends for the same IT load. This is because, efficiency of cooling units changes according to outdoor temperature. This efficiency gain is also the reason for increasing datacenter temperatures.
