As our digital addiction increases, the power we consume increases in parallel. By-product of the process is HEAT. This presentation introduces a reliable and energy-efficient method for data centers cooling.
Heat Loads In Data Centre
ADIA-MECHANIC Cooling
Adia-Mechanic Cooling is a highly efficient way of data centres cooling.
Working Principle
- When outdoor
temperature is cold enough, outdoor air flow used to cool the indoor air cycle while two air flows do not mix. (Free Cooling)
- On warm days, water
spraying to the outdoor air flow, increases cooling
- effect. (Indirect Adiabatic
Cooling)
- Mechanical cooling trims
the supply temperature on hot days.
Adia-Mechanic Cooler
- The unit uses air-to-air
heat exchanger for transferring data center’s heat with the
- utdoor air stream.
Indoor Air Cycle Outdoor Air Stream
Adia-Mechanic Cooler
- The most economical
mode of operation is achieved by using Free Cooling, Indirect Evaporative Cooling and Mechanical Cooling alone or together.
Why Adia-Mechanical Cooling Be Preferred
Advanced control algorithm ensures most efficient cooling methode, for reducing
- perating cost.
- Free Cooling (DRY)
- Adiabatic Cooling (WET)
- Mechanical Cooling (DX)
- Adiabatic + Mechanical Cooling
(WET+DX) Annual temperature hours (Istanbul as an example) shows savings potential. Most of the year the unit
- perates with free cooling and
indirect adiabatic cooling modes.

- Absolutely NO!
- Fan motors consumes
energy while free cooling process.
- More air flow required for
free cooling when outdoor temperature rises.
- More air flow requires more
energy consumption.

- pPUE is an indication of the
electrical energy consumption
- Water is another material
consumed for the cooling
- Operating cost is the sum of
electricity and water costs in currency units.
- Operating the unit with cost
control can be more economical.

Dehumidifying And Humidifying Processes
- Dehumidification is carried
- ut with the second cooling
cycle.
- One main and one spare
unit in each hall has the feature of humidification and / or dehumidification.
- Humidification is carried out
with a steam humidifier.
Control System
- In House Developed Unique
Control Algorithm Is The Most Important Compenent Of This System.
- Algorithm controls the amount
- f outside air to control the
supply temperature without fluctuation and with lower
- perational costs.
- Without PID, the unit can
calculate how much air flow should be for achiving the set supply temperature.
- This allows him to quickly reach
the target and stay at a constant temperature.

- Teamwork; All units
belonging to a hall are associated with the «Ring Topology».
- There is no way to loose
communication in the teamwork.
Machine Learning For Prediction And Control
- The temperature distribution
may not be homogeneous in the data room.
- By knowing the effect of each
unit in the hall and controlling them accordingly, homogeneous temperature distribution can be achieved.
- Doing this with machine
learning has been brought to the trial phase.
- The laboratory is located in the
Boreas production facility in Istanbul on an area of 300m2
