Points of Refrigerant Control (Cooling Operation)
Cooling mode is affected by the quantity, capacity, and fan speed of active indoor units. Indoor air temperature and humid-
ity also affect the mode.
▪ Adjusting the compressor capacity
Adjust the compressor speed to match the evaporation pressure to the target pressure. Evaporation pressure is measured
by the low pressure sensor on the outdoor unit in order to adjust the cooling capacity according to load.
▪ Adjust the indoor unit EEV to sync the refrigerant superheated degree for the indoor heat exchanger (formula: exit refrig-
erant temperature - entrance refrigerant temperature) with the target superheated degree.
