Points of Refrigerant Control (Heating 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.
ƒ Ad
justing the compressor capacity
Adjust the compressor speed to match the condensing pressure to the target pressure. Condensing pressure is measured
b
y the high pressure sensor on the outdoor unit in order to adjust the heating capacity according to load.
ƒ Adjust the outdoor unit EEV to sync the
refrigerant superheated degree for the outdoor heat exchanger (formula: com-
pressor suction temperature - low pressure saturation temperat
ure) with the target superheated degree.
ƒ Adjust the indoor unit EEV to sync the refrigerant supercooling degree for the indoor heat exchange
r (formula: high pres-
sure saturation temperature - entrance refrigerant temperature) with the target supercooling degree.
