Free cooling is an economical method of using low external air temperatures to assist in chilling water, which can then be used for industrial processes, or air conditioning systems.

Apr 19, 2018 · Free Cooling, simply put, is using colder ambient air (colder than the supply chilled water set point) to perform cooling rather than the refrigeration cycle of the chiller. In our HVAC-systems world, the proper technical name is waterside economizer.

May 24, 2024 · Free cooling is a system capable of harnessing the temperature difference with the external environment to cool indoor spaces without using refrigeration systems. As the summer season approaches and temperatures rise, air conditioning is increasingly used.

Free cooling is an approach to lowering the air temperature in a building or data center by using naturally cool air or water instead of mechanical refrigeration.

Jun 29, 2021 · A free cooling system reduces energy use by using a fluid cooler or cooling tower to cool the process fluid in place of a chiller. Now that system components have been defined, understanding a free cooling system is much more straightforward.

Jan 20, 2023 · Free cooling is a type of cooling system design. It uses ambient temperatures to reduce or eliminate the need for a chiller or compressor operation. Chillers often consume a larger amount of energy. Minimizing the chillers’ operating …

Feb 18, 2015 · Low ambient temperatures can be used as a “free” energy source, replacing the electricity required to run refrigeration compressors, in what is known as a free-cooling chiller system. Free-cooling systems are not new although differences in design efficiencies exist.

Free cooling is the process of using external ambient temperature to reject heat, rather than using the refrigeration process. If used within an optimised system, free cooling can provide significant energy savings.

This article will describe several general free cooling design schemes. In doing so, we will review the basic air conditioning scheme as it applies to free cooling and we will discuss the trade-offs involved in equipment selection.

Free Cooling is a dynamic, cost-effective method leveraging low external air temperatures for temperature control in industrial processes and HVAC systems. By harnessing naturally cooler outdoor air, free cooling eliminates the need for additional mechanical cooling equipment.
