8.COMPRESSOR CONTROL

1.OPEARTION FREQUENCY RANGE

The operation frequency of the compressor is different based on the operation mode as shown in the Table 11.

(Table 11 : Compressor frequency range)

	Cooling / Dry		Heating
	Minimum	Maximum	Minimum	Maximum
AOU09RL2	18rps	80rps	18rps	120rps
AOU12RL2		96rps

2.OPEARTION FREQUENCY CONTROL AT NORMAL START UP

The compressor frequency soon after the start-up is controlled as shown in the Fig.9. (Fig.9 : Compressor control at start-up)

3.LIMITATION OF COMPRESSOR FREQUENCY BY OUTDOOR TEMPERATURE

The minimum compressor frequency is limited by outdoor temperature as shown in the Table12.
