and above, the dimensions are taken with the piping on one side.2. When equipped with coil for both cold and hot water, the dimensions B of the model AA0045HR~AA1300HR can

be manufactured in 600mm, and AA1450HR and above, in 750mm.3. When coil piping is done for both directions in models AA1450HR and above, dimensions B can be manufactured in 750mm.

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

Sample specification- Chilled water coil: 8 Row, 10Fin/Inch - Air Filter: Glass Fiber material- Pass-through wind speed: 2.5m/s - Eliminator: Installed

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.

Air side static pressure drop

Fin pitch static pressuredrop correction factor

Through the above process 1,2,3

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

Check on the temperature correction factor for the air side pressure drop
