Free cooling

Free cooling works if the ambient temperature is lower than the required set point for the chilled water temperature. In this procedure, chilled water is cooled partially or completely using ambient air, so less energy is required to power the compressor. ENGIE Refrigeration offers options for internal and external free cooling for the air-cooled QUANTUM Air chillers. The most important benefits of free cooling systems include high levels of energy efficiency, lower power consumption and considerable savings.
