Data Centre Innovations & Benefits

Workspace Technology has developed its extensive expertise in data centre evaporative fresh air cooling over the past four years. This expertise has positioned Freecool® by Workspace Technology as the evaporative free air cooling solution of choice by many data centre operators. Freecool® offer data centre managers a range of innovations to help improve performance

Dual Filtration

freecool-dual-filtrationFreecool® Evaporative Free Air Cooling installations are designed as standard with a combination of G3 and G4 air intake filtration systems designed to eliminate data centre contamination.

Atemperation™

freecool-atemperationIntelligent atemperation™ is a system designed by Workspace Technology that blends hot exit air with cold intake air to produce controllable equipment inlet temperatures irrespective of external ambient conditions. Atemperation™ is delivered through a combination of variable speed fans and volume control air dampers positioned within a “mixing box” and controlled intelligent PLC systems.

Dynamic Mode Temperature Control

freecool-fan-graphConventional cooling systems typically require higher equipment intake temperatures to improve the performance of the free cool mode. Workspace Technology’s “Dynamic” mode of operation allows cold aisle /equipment inlet temperatures of 18°C for extended operating periods without compromising energy efficiency. Lower equipment inlet air temperature help reduce power demands of server fans whilst also improving overall equipment reliability*. When external ambient conditions rise above 18°C the Freecool® Dynamic Mode of operation simply allows the equipment inlet temperature to gradually rise falling back again as the external ambient decreases.
*Results will depend on equipment age and type of fan.

In Dynamic Mode the Freecool® control system can also be programmed to ramp up / down temperature (in-line with the rate of change parameters defined by ASHREA) to ensure humidity levels are maintained within class A1 data centre operating mode (10% to 80% RH).

Reduced Fan Power

freecool-ec-fan-150x68Power consumed by the Freecool® system is primarily related to fan power. Workspace Technology’s engineers only select energy efficiency EC fans because they use significantly less energy than conventional fan technology. EC stands for Electronically Commutated and is the term used when the fan is fitted with a permanent magnet motor (PMM).

EC technology allows continuous adjustment of fan speeds as required to support data centre cooling demands. The speed of each fan within the Freecool® system is individually modulated via the Freecool® Crouzet controller system. Typically fan selections are oversized to support N+1 system resilience and to allow reduced speeds during normal operating conditions. Because motor power associated with EC fans varies with the cube of the motor speed any reduction in fan speed will result in energy reductions. As an example a 20% decrease in fan speed results in a 49 % energy reduction.

Benefits of EC Fans over Traditional Fan Technology:

  • Reduced Energy Consumption
  • Improved Noise Reduction
  • Intelligent Electronic Control
