“We find the same thing”, says Jaimie Johnston.
the difference between the external air temperature and the chilled water outlet temperature.Every degree closer results in mechanical cooling being eliminated for potentially hundreds of hours, leading to significant energy savings.
In hot, dry climates, using adiabatic cooling which cools towards the wet bulb temperature which is often much lower than the dry bulb temperature, can further reduce the number of hours of mechanical cooling required.The balance between reducing energy / water consumption as part of the design is investigated as part of each project design.. Water usage.A growing challenge for data centre providers is water availability.
Data centres utilising evaporative cooling systems need a consistent water supply for process cooling and obtaining this can be increasingly difficult in some regions.Water stress levels (calculated by UN-Water) are low for European regions but there is much higher stress in North Africa and Asia, which may lead to fewer data centres obtaining water for process cooling.. Space efficiency of heat rejection plant.
The external heat rejection unit size is typically based on the required heat rejection capacity and approach temperature (external air inlet temperature vs CHW/air outlet temperature).
Generally, the heat rejection plant is located as close to the data halls as possible, however, where there is a drive towards higher density data centres the typical space for external heat rejection may be limited.This is a key aspect of Bryden Wood’s.
