Compressor Operation Frequency
8.1.2.1.
The frequency determination method (Cooling operation control)
8.1.2.1.1.
Basic specification
The domain directions data (intake-setting) transmitted from the interior of a room determines a changed part of frequency.
Then, a directed changed part changes frequency to the present frequency.
8.1.2.1.2.
Initial frequency determination
After a starting control end, initial frequency (absolute value) is determined.
However, a FcMAX domain judges instantly.
8.1.2.1.3.
Change frequency determination
When (Suction-setup) is +0.5deg, directions of Fcmax came by the mentioned initial frequency.
Fcmax continued until it reaches. (If other directions came by protection control, priority is given)
When room temperature is reached, it shifts to relative control after moving to change frequency.
The following operation determines change frequency.
The Hzkirikae = present condition frequency * Inclines and it is calculation.
Inclination = lapsed time to remote control attaintment (Minute)
Inclination
Inclination coefficient
1. The present frequency is real operation frequency.
2. When change directions come out with remote control after starting, continue calculation as it is.
The time to room temperature attainment is calculated.
3. When remote control directions were changed before room temperature attainment and below room temperature attainment
temperature becomes
With initial frequency, it is considered as change frequency.
