Claim Text:
1. A computer system, comprising: a computer cabinet having an air inlet spaced apart from an air outlet, and at least a first computer module compartment spaced apart from a second computer module compartment, wherein the air inlet, the air outlet, and the computer module compartments define an air flow path through the computer cabinet; at least one sensor operatively coupled to the computer cabinet; at least a first heat exchanger positioned upstream of the first computer module compartment in the air flow path, a second heat exchanger positioned between the first and second computer module compartments in the air flow path, and a third heat exchanger positioned downstream of the second computer module compartment in the air flow path; a heat removal system in fluid communication with the heat exchangers for circulating working fluid between the heat removal system and the heat exchangers; a control system operatively coupled to the at least one sensor, the control system having a computer-readable medium containing instructions for sequentially controlling the flow of working fluid to the third heat exchanger, the second heat exchanger, and then the first heat exchanger based on heat transfer between the computer cabinet and a room in which the computer cabinet is placed, as measured by the at least one sensor; and an air mover that moves cooling air through the computer cabinet along the air flow path and past the first and second heat exchangers to cool the working fluid circulating therethrough.
