To cool racks of electronic devices, the racks are arranged in a plurality of rows to define at least a first aisle and a second aisle, where the second aisle has air cooler than air in the first aisle, and where the fans of the electronic devices cause air to flow from the second aisle to the first aisle. A cooling coil assembly contains a coolant to cool air received from the first aisle, wherein cooled air exits the cooling coil assembly and flows to the second aisle. A temperature of the coolant in the cooling coil assembly is maintained above a dew point of an environment in which the racks are located.

1. A system comprising: a plurality of rows of racks, wherein the racks contain electronic devices, and the electronic devices comprise respective fans, wherein the plurality of rows of racks define at least a first aisle and second aisle, the second aisle having air cooler than air in the first ais
1. A system comprising: a plurality of rows of racks, wherein the racks contain electronic devices, and the electronic devices comprise respective fans, wherein the plurality of rows of racks define at least a first aisle and second aisle, the second aisle having air cooler than air in the first aisle, and wherein the fans of the electronic devices cause air to flow from the second aisle to the first aisle;a cooling coil assembly mounted to receive a flow of air from the first aisle to cool the flow of air, the cooled air to exit the cooling coil assembly to pass to the second aisle; anda controller to monitor a temperature of a coolant in the cooling coil assembly and to maintain the temperature of the coolant above a dew point of an environment in which the rows of racks are located. 2. The system of claim 1, further comprising a roof structure over the second aisle, wherein the cooling coil assembly is part of the roof structure. 3. The system of claim 1, further comprising a roof structure over the first aisle, wherein the cooling coil assembly is part of the roof structure. 4. The system of claim 1, wherein the cooling coil assembly is positioned between racks of one of the plurality of rows. 5. The system of claim 4, further comprising another cooling coil assembly positioned between racks of another one of the plurality of rows. 6. The system of claim 1, further comprising a temperature sensor to detect a temperature that indicates the temperature of the coolant, the temperature sensor to output a temperature measurement to the controller. 7. The system of claim 6, further comprising additional sensors to measure barometric pressure and humidity, wherein the controller is to determine the dew point based on the barometric pressure and the humidity. 8. The system of claim 1, wherein the controller is to maintain the temperature of the coolant by controlling compression of the coolant by a compressor and pump assembly. 9. The system of claim 1, wherein the flow of air from the second aisle to the first aisle is produced by the fans of the electronic devices without using additional fans. 10. The system of claim 1, wherein the plurality of rows define additional first and second aisles, wherein air in each of the second aisles is cooler than air in each of the first aisles, and wherein the electronic devices in the plurality of rows cause air to flow through corresponding electronic devices from the second aisles to the first aisles. 11. The system of claim 1, wherein the electronic devices are computers. 12. A method of cooling racks of electronic devices, comprising: arranging the racks in a plurality of rows to define at least a first aisle and a second aisle, the second aisle having air cooler than air in the first aisle, and wherein fans of the electronic devices cause air to flow from the second aisle to the first aisle; andproviding a cooling coil assembly containing a coolant to cool air received from the first aisle, wherein cooled air exits the cooling coil assembly and flows to the second aisle; andmaintaining a temperature of the coolant in the cooling coil assembly above a dew point of an environment in which the racks are located. 13. The method of claim 12, further comprising: receiving a temperature measurement from a temperature sensor associated with the cooling coil assembly, wherein the temperature measurement provides an indication of the temperature of the coolant. 14. The system of claim 13, further comprising: receiving measurements of barometric pressure and humidity; anddetermining the dew point based on the barometric pressure and the humidity.
