Using evaporative (swamp) coolers to provide outdoor air to reverse cycle ducted units
Using evaporative (swamp) coolers to provide outdoor air to reverse cycle ducted units
(OP)
A stupid question for experts here....
As you know it is pretty standard to use outdoor air fans to provide fresh air to the return air plenum of ducted fancoils...
I am wondering whether this is a good thing to use an evaporative cooler instead of a normal fan and turn on the pump during summer and turn it off in winter?
Couldn't find any application for this but really want to hear your opinions on this....pros/cons?

- What was your goal behind thinking to use the evaporative cooling.
- What are the location barometers and space served by this system.

The space could be any space but I am specifically looking at a pub that can open their doors any time. Using reversed cycle could be a big waste of energy and using evap cooler only makes the indoor uncomfortable at humid days.

evaporative cooling is a good idea if you have a low dry bulb environment, but you will need larger ducts (more aiflow needed), you may need as much as 20 to 30 Air changes per hour, depending on your ceiling height.
Look at "Indirect/Direct" type evaporative cooling systems literature for your application.
Consider using "dolphin" water treatment system for your make-up water.
