While there’s no disagreement that DOAS systems require some supplemental equipment to handle remaining sensible cooling loads, a couple of schools of thought have evolved regarding the best way to arrange certain terminal equipment within the overall system. Can this be a simple misunderstanding about one option’s ideal configuration? Can a 2,700% difference in power consumption really be a part of this discussion? Read on to find out.
This pairing can represent a great strategy - if you choose your tactics wisely. When is passive or active the better desiccant approach? When is one out of the question? We'll discuss how to control the latent load, arrive at a smart design decision for the circumstance, and consider recent research on first cost and performance.
In the event of a bioterrorist attack, would having a VAV or DOAS system make a difference? Would one system or another make a difference in the speed of flushing out the contaminant? Or in spreading contaminant through various spaces? Or does filtration selection come into play, too? The correct answer is yes, yes, yes, and yes.
