Supply Air Temp to Room Question.
Supply Air Temp to Room Question.
(OP)
Hi,
I am working on a fitness centre project where the interior space is very hot, around 29C. The design temp is 23C and the supply air off the AHU is 13C. However, the temp off the supply diffusers inside the premises is 16C and the temp further down the AHU duct is 17C. The building management insists that they have the design specs, displaying on their monitor. Any thoughts?
Thanks in advance.

It will be helpful in analyzing the problem if you give WBT and DBT of room inlet, outlet and coil inlet and outlet conditions.

Common sense already implies that it is too big temperature rise. If you don't have apparent heat source exactly on the position where there is a temperature rise, you should recheck BMS sensor (contractor's sensor can be checked even simpler: let him stick in duct different from the one he used first time). Maybe it didn't failed, it only needs recalibration (depending of the make of sensor). Maybe it did failed.
Don't let them say to you that they already checked it, if you are in charge for that, check once more. You can allways bet in drink or something like that to avoid them being offended by your recheck.
(After all maybe building management will only have to properly clean chiller condenser system heat exchange surfaces. Maybe.)
