3.2. CORRECTION FACTORS ACCORDING TO PIPING LENGTH
Correction Factor for Cooling Capacity according to
Piping Length
The cooling capacity should be corrected according to the
following formula:
CCA = CC x F
CCA: Actual Corrected Cooling Capacity
(kcal/h)
CC: Cooling Capacity in the Performance
Table (kcal/h)
F:
Correction Factor Based on the
Equivalent Piping Length
The correction factors are shown in the following figure.
Equivalent Piping Length for:
– One 90º Elbow is 0.5m.
– One 180º Curve is 1.5m.
OUTDOOR TEMPERATURE (°CDW)

L
Correction Factor for Heating Capacity according to
Piping Length
The heating capacity should be corrected according to the
following formula:
HCA=
HC x F
HCA: Actual Corrected Heating Capacity
(kcal/h)
HC: Heating Capacity in the Performance
Table (kcal/h)
F:
Correction Factor Based on the
Equivalent Piping Length
H:
Vertical Distance Between Indoor Unit and Outdoor
Units in Meters
L:
Actual One-Way Piping Length Between Indoor Unit
and Outdoor Unit in Meters
EL:
Equivalent Total Distance Between Indoor Unit and
Outdoor Unit in Meters
(Equivalent One-Way Piping Length)
