AHU condensation problem

[zenen]

Hello,

We ve just had a A.H.U. installation with a downflow configuration with raised floor.

After installing the unit, and during commissioning, when turn it on we have noticed condensation driping from the Drain Pan.
I may have to mention here that the raised floor has not yet being installed. Condensation maybe relevant to this? (i.e. air turbulance?)


Any advice welcome.

thanks

hi zenen,
is the drip tray piped up? is there a pee trap on the vertical pipework? is the air volume making the condence water splash over the drip tray? is it condenceation on the drip tray , or is it leaking ?

Assuming unit is level, a p-trap must be correctly installed to ensure water flow out of condensate pan.

check the air velocity leaving the coil,if it exceeds 1.8 m/s in ANY place condensate will carry over.Fan speed & proximity to coil can influence this; good luck!

Forgot the F'n Flare NUT. Welcome to Refrigeration Engineer. Think we can shorten your name to... ah., FFN, ' how's that? So, which part of Australia are do you live?.. Mike.

air volume making the condence water splash over the drip tray, i believe was the problem. After the raised floor installed we have no condensation problems.

thanks everyone

[zenen]

what flares have to do with condensation, I dont understand...

[forgothflarenut]

abbreviated,dear monkey!and yes,after 30 years I still occasionally forget the freaking flare nut!!!
as to your previous assertion,a true flare jedi would never boast of his prowess!

again.... what flares have to do with condensation mate?

zenen,I apologise for hijacking your post.I'm new to this forum(and forums as a whole) flares have nothing to do with condensation in this case,and i should continuue in the chat area,glad to hear you resolved your issue.
Cheers,FFN

Condensation occurs on flare nuts too!!!

Are you prejudice against flare nuts??? They need love too! And sometimes some condensation.
