1-5. Capacity compensation coefficient
¢ Compensation coefficient of pipe length
The tables give the compensation coefficient of pipe length owing to installation position (pipe length
and height difference). Pipe length and height difference are the length and the height difference be-
tween outdoor unit and indoor unit.
Cooling
Outdoor unit is higher
than indoor unit
Outdoor unit is lower
than indoor unit
Heating
Outdoor unit is higher
than indoor unit
Outdoor unit is lower
than indoor unit
¢ Compensation coefficient of frosting/defrosting (Heating
operation)
To take the effects of accumulated frost and defrosting operation on heating capacity into considera-
tion, the capacity of outdoor units should be corrected by compensation coefficient shown in the ta-
ble below.
