CAPACITY COMPENSATION COEFFICIENT

COMPENSATION COEFFICIENT OF PIPE LENGTH
„ „
The tables give the compensation coefficient of pipe length owing to installation position (pipe
length, height difference). Pipe length and height difference are the length and the height
difference between outdoor unit and indoor unit.

COMPENSATION COEFFICIENT OF FROSTING / DEFROSTING
„ „
(HEATING OPERATION)
To take the effects of accumulated frost and defrosting operation on heating capacity into
consideration, the capacity of outdoor unit should be corrected by compensation coefficient
shown in the table below.
