CAPACITY COMPENSATION COEFFICIENT

COMPENSATION COEFFICIENT OF PIPE LENGTH
„ „
The figures 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 the master 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 units should be corrected by compensation coefficient
shown in the table below.
