Patent ID: 7472558

Claim:
A method of determining optimal air conditioner control comprising: determining a power consumption of each of a plurality of servers and a power consumption of each of a plurality of computer room air conditioners; determining relevant factors between each of the servers and each of the air conditioners, wherein each relevant factor represents a percentage of a total cooling effect on one of the servers due to one of the air conditioners; calculating a number of calories processed by each air conditioner using the determined relevant factors and determining a total number of calories processed as a total heat processed load; calculating a percentage of the total heat processed load for each air conditioner by dividing the number of calories processed by each air conditioner by the total heat processed load; distributing a heat processed load to each air conditioner using a corresponding percentage of the total heat processed load; adjusting the corresponding percentage of the total heat processed load for each air conditioner using an operating efficiency curve; calculating a respective power to be consumed by each air conditioner by dividing the number of calories processed by each air conditioner by a corresponding coefficient of performance value; calculating an efficiency value by dividing a total power consumed by the servers by a total power consumed by the air conditioners; determining whether the efficiency value is a maximum efficiency value; and setting each air conditioner at the respective power to be consumed when the efficiency value is the maximum efficiency value.
