For TS units with ClimaDry Reheat coil applications,
calculate face velocity of the entering air. From the table
above, nd ESP for Reheat application. The loss includes
wet coil loss.
Example:
Reheat coil loss can be determined from the above table.
Coil velocity (FPM) = Airow (CFM) / Face Area (sq. ft.)
1. TSH036 has a face area of 4.86 sq. ft. (see physical
data table).
2. At 1,100 cfm, coil velocity (FPM) = 1,100 / 4.86 = 226
FPM
3. From above table, it will be necessary to subtract
0.037 from the blower performance ESP.
4. On medium speed, the TSH036 (without reheat - see
blower table) can deliver 1,100 CFM at 0.28 in. wg.
with the standard PSC motor; with the reheat coil, it
now delivers 1,085 CFM at 0.28 in. wg. or 1,100 CFM
at 0.24 in. wg.
5. If the decrease in airow is acceptable, no changes are
necessary. Otherwise, high speed fan should be used
to overcome the pressure drop of the reheat coil.
Unit minimum entering air temperature while in the
dehumidication, cooling, or continuous fan modes is
65ºF DB/55ºF WB. Operation below this minimum may
result in nuisance faults.
