Direct Outside Air Free Cooling
The rising costs of energy and the drive to be greener are resulting in greater demands to conserve energy, particularly within the growing IT Mission Critical environment.
Cooling data centres accounts for approximately 40% of the total energy usage per annum so, finding a cooling solution that minimises energy consumption and provides an environmentally sensitive solution makes perfect sense.
Using highly filtered direct free outside air is a tried and tested way of cooling Data Centres and can be utilised for most of the year minimising the time that condenser, compressor and fan operation is required which, in turn, extends the lifespan of your cooling equipment.
Utilising modulating quantities of direct free cooling offers potential savings of up to 90% for energy usage- especially in moderate and cold climates.
Perhaps that’s why the likes of Google, Microsoft and Amazon utilise direct outside air cooling solutions.
More about Free Cooling
By using direct outside free air, your mechanical cooling equipment such as condensers, compressors and fans are not constantly operating, saving you large amounts of energy. The adoption of ASHRAE Data Centre guidelines TC9.9 has significantly reduced the need for mechanical cooling to a few hours, if at all, per annum, resulting in substantial energy savings, whilst also extending the expected lifespan of the cooling equipment.
By raising the supply air temperature, the number of days where direct free cooling can be utilised increases substantially resulting in significantly lower energy costs.
The benefits of direct outside air cooling can be further enhanced when aisle containment is incorporated into the Data Centre (as indicated below).
