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	18rps	96rps	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.

(Table12 : Limitation of Compressor Frequency)
