MISSION CRITICAL
transport medium of water or glycol . It changes the dynamics of the outside of buildings because you have the same problem – to deliver enough air inside the data centre to all the IT boxes to deliver processing power , whilst on the outside you have containment issues to squeeze all the large air movement devices into a small space with changing ambient conditions and wind profiles . Therefore , it becomes just as important to simulate outside conditions , which could be potentially catastrophic when they are delivering 30 % of your cooling .” Weighing up predictions for the future of the industry , King notes an increase in the complexity of control systems for cooling , moving away from individual air handlers to systembased buildings . “ We ’ re not sure complexity means better , but we ’ re certainly seeing examples where the complexity doesn ’ t seem to be
The performance of air cooling technologies can be established quickly and with great cost efficiency in the VF . It allows you to experiment in a virtual sandbox that will keep your costs to market to an absolute minimum . Here , the impact of varying return air temperatures on the heat exchanger performance is investigated
