Abstract

A temperature control system and method uses a market-based approach to control the temperature of regions within an unpartitioned space, such as a computer data center. Market agents may be associated with regions of the data center that may contain one or more heat-generating processor racks. Prices for the thermal resources may be established. The market agents may generate bids for thermal resources to be delivered to the respective regions. The bids may be based in part on differences between the measured temperatures and the target temperatures of the regions. Sets of the market agents are assigned to control of sets of thermal resources. Delivery of the thermal resources to the regions is controlled by the market agents.
