Cooling system for data centres maximises free cooling

Hoval’s ServeLine system for cooling data centres avoids the need for mechanical cooling for about 97% over overall operating times, in accordance with ASHRAE TC9.9 ‘Data center networking equipment — issues and best practices’. The ServeLine concept uses three forms of cooling, with mechanical cooling introduced only when required to meet unusually high cooling loads.

The first stage is indirect cooling with fresh air, supplemented with low-energy adiabatic cooling when necessary.

Control is via the ServeNet control system, which records all relevant parameters, compares current efficiencies of the three cooling mechanisms and optimises their interaction.

ServeNet can be fully integrated into the data centre infrastructure management (DCIM) and supplies all information for evaluating PUE (power usage effectiveness).

Indirect cooling via plate heat exchangers eliminates the risk to IT equipment from dust or humidity variations. In an emergency, the system ensures the data centre can be cooled exclusively by chilled water.

The modular configuration of ServeLine makes it a scalable solution for all sizes of data centre from 100 m2 upwards. The system can be extended if the data centre grows. Units can be sited internally or externally.
