High density

With end users looking to host equipment loads of 20kW plus in data
rooms designed to provide 4kW provision per racks space, you can
quickly see a provision gap between “available” and “desired”. There are
a number of solutions or options available to end users depending on site
constraints.

Cooling mediums

Fresh air – Commonly referred to as forced air or free cooling.
• The air in the data room is purged and replaced with external ambient air
• No temperature / humidity control
• Very low cost
• Limited ability to cool high density loads

Chilled water - Sometimes referred to as water to air heat exchangers.

• Simple water pumped through radiators (like your car).

IMPORTANT • Tight control of temperature and humidity.
• Higher CAPEX cost when compared to DX but lower OPEX

Managing heat is critical in avoiding downtime, • Can cool high density loads

reducing energy consumption and ultimately • Best free cooling solution (apart from fresh air)
improving PUE. • Smaller Data Centre units

application. • Freon gas expanded rapidly

• Tight control of temperature / humidity

• Relatively low cost

• Can cool high density loads

• Limited ability to offer free cooling and inherently higher OPEX

• Large Data Centre units required but smaller external condensers

Chilled water

Remains one of the most popular mediums for removing heat from the air
within a contained data room due to;

• Offers the option of maintaining a contained and controlled environment.
• Is a proven and safe medium for heat transfer in the data room environment
• Many sites already having chilled water available as most CRAC units employ technology
• Offers scalability and when coupled with free cooling technology offers low OPEX costs
