Types of Free Cooling Systems
Free cooling can be achieved in various ways, and the right solution is very much dependent on project specific needs.
In industrial process cooling applications, free cooling typically works as either an integrated system - with a built in free cooling coil attached to the chiller - or as a standalone free cooler that works alongside a separate chiller.
Integrated systems are ideal for sites where space is an issue, as they’re far more compact than their counterparts. However, the additional coil can interrupt airflow when not in use. So, whilst you’ll benefit from full or partial free cooling when outdoor conditions are optimal, you may experience a drop in efficiency when they’re not.
With a standalone free cooler, you have flexibility with sizing, meaning a larger surface area and thus greater cooling capacity. And because it’s a separate system, there’s no impact on your chiller’s efficiency when free cooling is not possible.
There’s an added bonus to a standalone system in that it can be retrofitted. So space permitting, you can benefit from increased efficiency without replacing your existing chiller.
