Air Flow Detection in Data Cooling Center: Different Approaches

The lone purpose of data center is to handle data flow in different electronics equipment. Maintaining heat balance is a challenging task with monitoring of different parameters in the cooling center to prevent damage to the electronic devices. Air flow detection is a vital parameter for accurate heat detection and increasing the life of the data center. Paper discusses three different approaches for maintaining environment by sensing air pressure variations for air flow detection in the cooling center. The main challenge is of low air velocity up to 5m/s with low pressure up to 10 Pascal. In this challenge, first approach shows the experimentation with obstruction based pressure variation and sensing it with accelerometer. Second approach uses pressure variations generated due to bluff body placed in the air flow path and piezoelectric sensing of air variations. Third approach is evolved on the basis of pitot tube air flow sensing method. Each method is explored and through experimentation proved for its limitations.
