8. COMPRESSOR CONTROL
01-08
1. OPEARTION FREQUENCY RANGE
The operation frequency of the compressor is different based on the operation mode as
shown in the Table 11.

2. OPEARTION FREQUENCY CONTROL AT NORMAL START UP
The compressor frequency soon after the start-up is controlled as shown in the Fig.9.
