Cooling data centres
A lot of heat is released in data centres and this has to be dissipated in a cost-effective and environmentally friendly manner. Indirect cooling with fresh air provides the ideal solution here (tip 2: indirect fresh air cooling). It involves the extract air in the heat exchanger being cooled by the fresh air and then being blown back into the server room.
Plate heat exchangers are used so that the air in the server room remains completely separate from the fresh air and to eliminate the possibility of dust or variations in fresh air humidity affecting highly sensitive IT equipment.
The system uses the interaction of different resources depending on the conditions to achieve energy-saving cooling:
- Indirect cooling with fresh air
- Indirect adiabatic cooling
- Mechanical aftercooling
Key requirements
To achieve cost-effective operation, the plate heat exchanger needs to be highly efficient, which is why two plate heat exchangers are often connected in series. It is important that the plate heat exchangers are absolutely tight, as the server room must not be contaminated.
Due to the possibility of adiabatic cooling, the exchanger should be protected against corrosion (epoxy coating). The water used must have the specified quality.
