5.2 Piping length correction factor
The correction factor is based on the equivalent piping length in meters (EL)
and the height difference between outdoor and indoor units in meters (H).
H:
Height difference between indoor unit and outdoor unit (m).
• H>0: Position of
outdoor unit is higher than position of indoor unit (m).
• H<0: Position of outdoor unit is lower than position of indoor unit (m).
L:
Actual one-way pi
ping length between indoor unit and outdoor unit (m).
EL: Equivalent one-way piping length between indoor unit and outdoor unit (m).
