24
comptressor:75HZ.
When30
℃ ≤ Ta ＜ 47 ℃ ,it open as cooling mode normal, the maximum work frequency of
compressor:85Hz
When16
℃
≤ Ta
＜
30
℃
, it open as cooling mode normal, the maximum work frequency of
compressor 65Hz
When Ta
＜
16
℃
,the maximum work frequency of compressor 37Hz.
4. Dehumidification mode
1
、
Under dehumidification operation mode, if the setting temperature cannot adjust, the default
setting temperature is 24
℃
;if the setting temperature can adjust, it is subject to the setting
temperature of the remote controller .
2
、 When Tr ＞ Ts+2 ℃ , the work mode as same as cooling mode, the speed according to the
remote control.
When Ts
＜
Tr ≤ Ts+2
℃
,the frequency of compressor is as same as cooling mode, indoor fan
running at low speed.
when Tr
≤ Ts, the compressor work at 10mins (frequency:30Hz) stop 6 mins alternately, in this
state, the open and shut down of compressor must meet 3 mins delay protection, the indoor
fan work at low speed when the compressor work, while the compressor shutdown at the
same time the indoor fan shut down.
when Tr
≤ 15
℃
, the compressor meets the work time ≥ 5mins,the indoor fan as well as outdoor
fan will stop.
3
、
The movement rate of frequency is 1Hz/s when it under dehumidification operation, and the
operating frequency Ta will be restricted as cooling mode.
4
、
In dehumidification operational mode, it can set as automatically, high, medium, low wind,
and the automatic wind speed can controlled as follows,
when Tr
≥ Ts+5 ℃ ,high speed
when Ts+3 ℃ ≤ Tr
<
Ts+5 ℃ ,medium speed.
At automatic speed, when the wind speed from low switching high, the wind speed without
delay; while from high switching low, there will be delay with 3 mins.
5
、 The functions of dehumidification are as follows: time setting, auto start, Anion, I feel.
6
、
The order of on/off of the outdoor fan, compressor are as same as cooling mode.
7
、
There are anti-freeze protection of evaporator under dehumidification operation mode.
5. Wind Mode
Outdoor unit keep closing at the wind mode and the indoor motor run at the certain wind
speed .Remote Controller get 3 speed mode including high speed
、 middle speed and low
speed without automatic wind.Working
Condition of air blade is as the same as cooling mode including timer
、
negative ion
、
I feel and auto restart.
6. Heating Mode
1
、
The certain temperature which fall within the range from 16
℃ ～
32 depend on Remote
℃
Controller,the
Temperature precision should be
±
1 and Controller box roughly adjust th ℃ e working condition
of compressor and the speed of indoor motor in order to achive the best working condition
according to the difference between indoor temperature & certain temperature and the change
rate of indoor temperature.
2
、
Start frequency of compressor:20Hz;
3
、
Working frequency & up and down frequency
It should be 60Hz when compressor start,stable working condition ≥ 60s;
