Outdoor fan control
(a)
Outdoor fan speed and fan motor rotation speed.
The 7th outdoor fan speed in the following table is
specified
as the rated speed. Under the normal control, the speeds up
to 8th level (800 min
−
1
) are used.
Note (1) Figures in the parentheses in the above table are applicable to FDCR224KXE6.
(b)
Fan control during cooling
During cooling and dehumidifying, fan speed is controlled in accordance with the high pressure (sensed by PSH) and the
outdoor air temperature (sensed by Tho-A).
(i)
Initial fan speeds are as follows.
Initial ourdoor fan speed at cooling
(ii)
During normal operation, the speed is changed in accordance with the high pressure value.
When it has detected HP
≧
2.2 MPa for 1 minute continuously, the fan speed is raised by one tap.
When it is 1.5 MPa < HP < 2.2 MPa, the present fan speed is maintained.
When it has detected HP
≦
1.5 MPa for 1 minute continuously, the fan speed is dropped by one tap.
Control range of fan speed is 1th – 8th speeds.
(iii)
When states under this control change from HP < 3.3 MPa to HP
≧
3.3 MPa, the fan speed is changed preferentially
to the followings. (After the change it returns to the normal control.)
When the outdoor air temperature
≧
30ºC, it changes to 7th or higher speed.
When the outdoor air temperature < 30ºC, it changes to 3rd or higher speed.
When the fan speed was higher than the above before the change of states, the fan speed is not changed.
