Free cooling is an economical method of using low external air temperatures to assist in chilling water. This chilled water can then be used for air conditioning systems. This approach is generally an option during late fall, winter, and early spring.
When the ambient air temperature drops to a set temperature a modulating valve allows all or part of the water to bypass the chiller. This approach uses less power by taking advantage of the lower ambient air temperature for cooling.
If the outdoor temperatures are low enough the water is chilled solely by means of the Free Cooling coil. Without the chiller’s compressors operating significant amounts of energy are saved. The only electrical power used during the winter is for operating the fans.
