Cold weather isn’t all bad – it could help you significantly reduce your energy costs through a process known as Free Cooling.
How does it work?
Free Cooling uses low external air temperatures to assist in cooling water for industrial temperature control applications or in HVAC systems. It is fast, effective and extremely economical, particularly in parts of the world with cold seasons where energy savings of up to 70% can be achieved.
A chiller’s traditional design uses integral compressor technology to generate the cooling required for process and HVAC applications. The use of Free Cooling in an industrial temperature control application differs from an environmental cooling solution as fresh ambient air cannot be drawn straight into the cooling circuit. Therefore, to harness the benefits of the low ambient temperatures, a Free Cooling coil needs to be introduced into the circuit.
A Free Cooling coil is installed in series with the chiller system’s evaporator so in lower ambient conditions, partial or 100%, Free Cooling can be achieved.
Partial Free Cooling
The ambient air temperature needs to drop at least a degree below the process return water temperature for Free Cooling to begin – the external ambient temperature can then be used to help cool a process in place of a chiller.
100% Free Cooling
As the ambient temperature drops 3°C to 5°C below the required process supply water temperature total Free Cooling can be achieved – taking over from the chiller’s compressors and consequently providing an environmentally friendly and cost-effective approach to process and HVAC cooling.
As a leading supplier of temperature control solutions, ICS Cool Energy is able to offer Free Cooling systems for both sale and hire to ensure customers achieve the greatest energy savings to suit their business and application requirements.
