Free Cooling

 

Free Cooling Air Cooled Chillers 
 
A major factor that can influence power usage effectiveness (PUE) in a data center is the type of cooling system deployed and whether or not it includes free cooling.
Free cooling is the ability to leverage existing local ambient conditions to reduce energy usage. There are several latitudes and elevations around the world where data center managers can reduce the use of CRAC units and associated cooling costs by taking advantage of outside environmental conditions. According to reports by HIS, the market for free cooling technologies will grow faster than any other cooling methods over the next four years.
 
Features
Free cooling is a cooling technique that allows the shutdown of the compressors when the outside temperatures are low, producing a considerable reduction in electric consumption for the air conditioning system.
 
The direct free cooling system consists in the direct entry of the outside air into the room, if the outside air has a lower temperature than indoor air.
 
Benefits
Energy saving.
The energy saving will be higher the longer the outside temperature remains below the required temperature for cooling.
 
 
Free Cooling Feature can be achieved in 2 range of products :
 
IT Chillers :
Most of the  Air Cooled Chillers produced by RC Group is a type of liquid chillers equipped with a built-in additional coil making Free Cooling using the outdoor air as cooling media.
 
The free-cooling system installed on these chillers has been designed and applied by RC GROUP for the first time in the early 70’s and the today’s series is the result of this experience.
 
These chillers allow to achieve remarkable energy savings when installed in cold and temperate climate zones.

Closed Control Air Conditioners :
Free cooling option is available as option on most of the closed control air conditioning systems .this feature is managed by the microprocessor controls and  dual source free-cooling system:
direct free-cooling with direct introduction into the room of ambient air, or water indirect free-cooling with a dedicated heat exchanger.
According to the set-point and the energy saving logic the controller activates the free-cooling system more affordable.
