Computer Room Air-Handler Bypass: A Novel Approach for Reducing the Cooling Infrastructure Power Consumption in Air-Cooled Data Centers

A novel method is proposed to reduce the power consumed by data centers cooling infrastructure, blowers and chillers. This method is applied to enclosed aisle configurations in which the CRAH is partially bypassed by inducing hot air into the plenum. This slightly depresses the plenum pressure and eliminates wasteful leakage of cold air. The proposed approach decreases the CRAH blower power and leads to a substantial reduction in the combined power consumption of blowers/fans and chillers.
