Sample specification - chilled water coil- Coil : 8 Row, 10Fin/Inch - Coil inlet air temperature(DB1) : 28- Pass-through wind speed : 2.5m/s - Coil outlet air temperature(DB2) : 18
Basic specification1. Model: AA0300H2. Cooling caloric value : 135,000 kcal/h3. Specification of coil : 6Row 30 Pass 1,740mm4. Inlet and outlet temperature difference : 5
When cold and hot water coil is used, the pressure drop on thewater side is calculated from the flow rate per tube Pass bundleand the length (effective length) of tube.
Note Recommended water speed inside the coil is 0.5~2.3m/s.

Correction factor on theaverage dry bulb airtemperature at the coil inletand outlet
Using the static pressure drop curve at the air side of the chilled water coil,intersection between pass-through wind speed(2.5m/s) and number of coilrows (8Row) is taken
Air side static pressure drop x fin pitch static pressure drop correction factorx correction factor on the average dry bulb temperature of the coil inlet andoutlet air =15.8mmAq x 1.35 x1.02

The following coil performance tables (table25, table26, table27) are based on the standard operation condition, which need to be corrected depending on the conditions of use.
In case the operation condition is the same with the standard operation condition: Refer to the chilled water coil performance table, hot water coil performance table and the steam coil performance tableIn case the operation condition is different from the standard operation condition: coil performance= coil performance table (table25, table26, table27) X heat transfer correction factor of the fin (table21) X coil performance correction factor (table22, table23, table24)
