ColdLogik Proactive RDC Benefits

Energy Saving

There are many energy metrics used within different industries – the air conditioning industry uses the European Seasonal Energy Efficiency Ratio (ESEER) and data centers often refer to PUE (power usage effectiveness. ESEER refers to the efficiency of purely the cooling equipment whilst PUE looks at the ratios of equipment energy usage vs the energy used in the building.

Power Usage Effectivness (PUE)

The PUE may vary between 1.03 and 1.5 depending on the geographical location and external ColdLogik cooling solution chosen to pair with ColdLogik Rear Door Coolers, site conditions and architecture. Properly designed ColdLogik installations can be between 1.03 and 1.1 for the full datacenter at full load. These figures are not based on partial PUE but refer to the full DC environment.

What is Sensible cooling?

Sensible cooling is the process of cooling air so that the temperature and relative humidity doesn’t pass below ‘dew point’. This is the point at which relative humidity becomes too high and water will start to be collected at the point of cooling. Condensation will not occur by operating at higher water temperatures. This will still neutralise the same amount of heat whilst also avoiding the dew point and with it the need to manage condensate in the space.

What is Free cooling?

As the title states, the chosen cooling solution should have the ability to provide free cooling i.e. cooling at as close to zero energy cost.  Our technology allows us to use external environmental conditions to provide this free cooling, which can be derived from ambient air, hybrid chillers, adiabatic coolers, cooling towers, rivers, sea, bore holes etc.. And depending upon the chosen holistic solution this can be for up to 100 percent of the year. This can also lead to an ESEER of over 100 for the complete system.

All of which can lead to PUE’s being as low as 1.03 – proven!
