Effect of Chilled Water Coil Piped Backwards
(OP)
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?
