Operation of a compressor shall be performed after adjusting priority to prevent operating time from being concen-
trated on only certain compressor. Add the first priority to a compressor with less operational time accumulated
during the operation of an outdoor unit.
Operate additional compressor in case the operating frequency are operated at more than 76Hz or at more than
60Hz for 3 minutes while the outdoor unit is operated only with one compressor. It is designed that the efficiency
of the compressor is operated in the most ideal section.
■ Compressor priority in an unit
1. Which stopped longer
2. INV1 at initial starting from power supply
■ Additional compressor starting condition.
1. Over 60Hz & over 3mins operation
2. Over 76Hz operation
※
Efficiency of 30~80Hz is better than higher frequency
※
Each unit will decide individually
The capacity of the outdoor unit and a compressor shall be distributed to optimize its performance with each oper-
ating. The capacity during outdoor period shall be distributed based on the capacity ratio. The operating capacity
distributed to each outdoor unit shall be redistributed by each compressor. It shall be operated starting from the
low frequency so that the calculated frequency can be operated within a certain scope established and the fre-
quency shall be raised by entering the comp operation capacity control.
