Freecool Evaporative Free Air Cooling Technology – Reducing Carbon Emissions by use of FreeCool®

FreeCool® by Workspace Technology is an evaporative free air economizer technology that delivers consistent equipment inlet temperatures of 21ºC to 24ºC depending on client preferences. The dew point temperatures simply do not become an issue due to the practical working temperatures.

In the past these solutions have been dismissed for server room and data centre building environments due to historical issues with quality and humidity control. Workspace Technology’s solution challenges the barriers to this type of cooling as a suitable technology for server room and data centre environments.

The barriers have been removed as the design of modern computing equipment is much more robust with regards to both heat and humidity.

Typical computer manufacturer climate operating specifications are 10ºC to 35ºC and 10% to 95% relative humidity. ASHREA* have acknowledged the advances of modern computers and the need to balance energy efficiency against system reliability. Recently published ASHREA documents make recommendations for a server room temperature range of 18ºC to 27ºC, it is recommended that humidity levels are replaced with dew point.

The use of high specification filters removes smaller particulates associated with construction, traffic, industrial processes and other pollutant material. The resultant cleanliness of outside air from FreeCool® is suitably appropriate for delivery within data centre environments.

FreeCool® Installation Benefits
Our technology makes the use of outside air to cool server room and data centre equipment. Unlike simple air economizers which require supplemental DX or Chilled water cooling when external ambient temperatures exceed 21ºC our system engages the evaporative cooling mechanism which reduces actual external air temperature by simply passing the airflow through wet filter pads.

FreeCool® deployment benefits include:-

  • Reduced CO² emissions
  • Significantly reduced energy consumption and operating costs
  • Supports existing cooling technologies
  • Improved DCiE / PUE ** Efficiency Ratings
  • Improved company “Green Credentials”
  • Improved resilience with practical support by UPS systems.
  • Flexible airflow configuration plan options

* ASHREA – American Society for Heating, Refrigeration and air-conditioning
** Data Centre Infrastructure Efficiency / Power Usage Effectiveness are industry recognized standards for data centre room efficiency measurement introduced by the Green Grid.
