What is a direct and an indirect free cooling system?
The new dimension of free cooling !
STULZ IT Cooling Solutions and Services 10
…free cooling is not a new technology- at least not in this region!
Indirect free coolingindirect: water/glycol will be used as a medium between the inside and outside
Direct free coolingdirecf: a huge part of the ambient air will be deliveredinside the data centre
Cooling the room without compressor operation: FREE COOLING
Free cooling for IT-rooms

NEW CONCEPTS: STULZ Direct Free Cooling with optimised coil placement
STULZ IT Cooling Solutions and Services 27
NEW CONCEPTS: STULZ Direct Free Cooling!
Advantages:
High energy efficiancy by using direct free cooling technology –no losses by additional heat exchangers
High scalibility of the system „Build as you grow!“ –no hydraulics (pipework, pumps, valves) at day 1 needed for the final stage
Lower CAPEX compared with indirect free cooling systems
Lower OPEX (energy consumption) the on all other systems
STULZ IT Cooling Solutions and Services 28
NEW CONCEPTS: STULZ Direct Free Cooling!Conditions:
Accepted room humidity level at approx. 20%- 80% r.H.
Ambient conditions need to be observed (dust) while selecting the site (not close to highways, harvest or in the city centres)
Acceptance of possible ourside influences(e. g. smoke, gas, etc.)
Compromising the building safety
Structural conditions:
Free in the construction of the building
short distances of the air intake and extract (pressure losses)
Air intake on the shadow side of the building
