When to Combine Storage with Free Cooling
Knowing when to combine storage with free cooling can significantly cut chiller runtime and peak demand costs for facility engineers and energy managers. This guide covers the conditions that make the combination worth designing and what the fabrication scope must include. What Free Cooling Actually Is Free cooling, also called economizer mode, uses a heat exchanger to transfer cooling capacity from an ambient source, typically outdoor air or a ground loop, directly to the chilled water system without running the
