<div dir="ltr">Dear Jim
<div><br>
</div>
<div>The two-stage evaporative cooler consists of an indirect heat exchanger and direct evaporative cooler. The first stage usually employs indirect contact cooling of primary air stream using another air stream called secondary air stream. For my research
work I am considering a wet-coil indirect evaporative cooler. Below is the diagram of secondary and primary air streams used in an indirect evaporative cooler.</div>

</div>
<div>I wish to <b>recirculate the secondary air stream (in proportion) to the zone </b>which is generally exhausted to atmosphere.Please find attached the block diagram of what I intend to do.</div>
<div>Hope the block diagram clearly explains the problem. It will be great if anyone can guide me through.</div>
