Abstract
An air flow control method and system for cooling a data center including two server rooms is disclosed. The method includes receiving a first differential pressure value; receiving a second differential pressure value from the second differential pressure gauge; generating a first control signal to adjust the opening of the first damper based on the first differential pressure value; generating a second control signal to adjust the opening of the second damper based on the second differential pressure value.

An air flow control method for cooling a data center comprising at least a first server room and a second server room, the first server room comprising a first chamber and a second chamber partitioned therebetween by a first server rack and being in fluid communication therebetween via the first server rack, the first chamber having a first air inlet fluidly coupled to an outside area of the server room, the second chamber having an air outlet fluidly coupled to the outside area, the second server room comprising a third chamber and a fourth chamber partitioned therebetween by a second server rack and being in fluid communication therebetween via the second server rack, the third chamber having a second air inlet fluidly coupled to the outside of the data center, and the fourth chamber being fluidly coupled to the second chamber, the method being executable by a controller unit coupled to:
- a first damper partitioning the second chamber into a first portion and a second portion fluidly coupled to the air outlet, the first damper configured to control the amount of air to flow from the first portion into the second portion;
- a second damper partitioning the fourth chamber into a third portion and a fourth portion fluidly coupled to the air outlet, the second damper configured to control the amount of air to flow from the third portion into the fourth portion;
- a first differential pressure gauge configured to measure a first differential pressure value of an air pressure of the first portion relative to the air pressure of the outside area;
- a second differential pressure gauge configured to measure a second differential pressure value of an air pressure of the third portion relative to the air pressure of the outside area;
