Cooling system with desiccant dehumidification

摘要

A system for removing heat from electrical systems includes a dehumidification device including a desiccant, an evaporative cooling device, air moving devices, and an air flow control devices. The air moving device moves air through the dehumidification device, the evaporative cooling device, and the electrical systems. The air flow control device controls a rate of flow through the dehumidification device.

1. A data center, comprising:
a plurality of electrical devices comprising heat producing components; and a cooling system, comprising:
one or more desiccant wheels;one or more evaporative cooling devices downstream from at least one of the desiccant wheels, wherein the one or more evaporative cooling devices are configured to evaporate a liquid into a stream of air flowing through the one or more evaporative cooling devices to cool the stream of air;one or more air moving devices; andone or more air flow control devices; wherein at least one of the air moving devices is configured to move air through at least one of the desiccant wheels, at least of the one or more evaporative cooling devices, and at least one of the heat producing components of the electrical devices, wherein the cooling system is configured such that at least a portion of the stream of air that flows through the one or more evaporative cooling devices flows through at least one of the desiccant wheels upstream of the one or more evaporative cooling devices and at least another portion of the stream of air that flows through the one or more evaporative cooling devices bypasses the at least one of the desiccant wheels upstream of the one or more evaporative cooling devices; wherein at least one of the air flow control devices is configured to adjust the at least a portion of the stream of air that flows through the at least one of the desiccant wheels.
