Dew Condensation Sweating Prevention Function
Outline
During Cooling/Dry operation, when the heat exchanger’s temperature falls down excessively,
the capacity supply will be reduced (frequency step down) so as to prevent dew formation
around a discharge grille caused by a excessive capacity supply to an indoor unit.
Processing
1. Conditions of beginning/ending for this function.
���
Operation mode is in Cooling/Dry.
���
Compressors operate.
���
Fan speed < MH tap
���
Outdoor temperature
≤
32°C
Dew condensation sweating prevention function will start, if
������������
are under the
simultaneous condition with AND.
���
Operation mode is not in Cooling/Dry.
���
Compressors stop
���
MH tap
≤
fan speed
���
Outdoor temperature > 32°C
Dew condensation sweating prevention function will be completed if
������������
are under the
coordinate condition with OR.
2. Control details
"
It controls the operation frequency in accordance with the temperature zone in the step
down area ~ the return area which are set in every model.
"
Frequency limitation by means of freeze protection control will not be carried out in the return
area.
"
Frequency is increased approximately every 2 Hz/min. in the up-area.
"
Frequency alteration will not be conducted in the steady area.
"
Frequency - down is carried out in the step down area approximately every 2 ~ 4 Hz/min.
