Free Cooling

What is 'Free Cooling'?

'Free Cooling' or 'Free Air' control system uses the ambient outside air temperature to cool your server / UPS machines without the use of air conditioning, which can be costly to run. There are 2 key benefits of an ecomec installed free cooling system:

  • Reducing your business air cooling costs of between 20% - 75% compared to a normal close control air conditioning system
  • Reducing your business carbon footprint by reducing your demand for electricity

How Does It Work?

It works using your existing close control air conditioning systems, but with additional supply/extract fans, ductwork, dampers, sensors and a control system monitoring the outdoor air temperature 24/7 to establish when filtrated fresh air can be used to cool your server and UPS systems, switching back to your original air conditioning when the ambient air is too warm. The outdoor air temperature is monitored on a real-time basis ensuring maximum free cooling and maximum cost reductions.

F-Gas Survey

F-Gases are the commonest refrigerants in air conditioning, heat pumps and refrigeration systems. They contain HFCs (Hydrofluorocarbons) which affect global warming if they escape into the air. The European Union's F-Gas Regulation No 842/2006 became law on 4 July 2006 to minimise emissions of these gases and is being imposed by a timetable of compliance deadlines - click here for further details.
