Effect of Chilled Water Coil Piped Backwards

[BronYrAur]

Anyone know the efficiency loss of a chilled water coil that is piped backwards (i.e. NOT Counterflow to the air)?

I have a 50.6 sqft, 8-row, 11 FPI, double-circuited coil that is piped wrong. Original sizing conditions were:

EWT 42 deg F
LWT 60.79 deg F
EADB 80 deg F
EAWB 67 deg F
LADB 54.48deg F
LAWB 54.28 deg F
Water flow 100 GPM
Air flow 24,000 CFM
Total MBH 940.1
Sensible MBH 669.84
1/2" copper tubes with AL fins

With the flow going the wrong way, any easy to predict what will happen to my heat transfer?

It could be as high as 15 to 20%.

Did a quick google search for "chilled water coils piped backwards"
and couldn't believe the number of hits......

leaving water and leaving air temps will be close to each other, as a guess the average of what they enter at.

lol, you have a low water flow rate, it leaves at the average as it is.
