If your building is in a geographic area with ideal seasonal temperatures and humidity, consider yourself lucky. Why? Because we can significantly reduce our air-conditioning operating costs by ensuring the air-side economizers are operating at peak performance. Delay turning on all those expensive to operate mechanical cooling systems when FREE outside air can be utilized. If we ignore those economizers, what happens? Operating costs go up, shortened HVAC equipment life span, consumable parts need replaced more often, and the list goes on. In this video, we’ll step you through each of the free-cooling modes and what to look out for.
