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
HC: Heating Capacity in the Performance Table
F: Correction Factor Based on the Equivalent Piping Length
The correction factors are shown in the figure.
Equivalent Piping Length for
• One 90
o
Elbow is 1.6ft (0.5m).
• One 180
o
Bend is 4.9ft (1.5m).
• One Multi-Kit is 1.6ft (0.5m).
* Liquid piping size for Equivalent Piping Length < 328ft [100m] and Equivalent Piping Length ≥ 328ft [100m]
are different. Refer to the “Installation Manual for Outdoor Unit” or Section 2.14.2 “Piping Size and Multi-Kit
Selection” for details.
H: Vertical Distance Between Indoor Unit and Outdoor Unit
EL: Equivalent Total Distance Between Indoor Unit and
Outdoor Unit (Equivalent One-Way Piping Length)
H>0: Position of Outdoor Unit Higher Than Position of Indoor Unit
