Remarks: the above are not only the maximum frequency limitations of the complete appliance
which are affected by the environment, but also the maximum ability limitation of the system. When the
starting ability is not the maximum, its maximum frequency limitation is calculated by the following
equations:
The frequency limitation which is affected by the temperature and under the condition of actual
ability the actual running system ability*the maximum frequency which is limited by the temperature
and under the condition of maximum ability/the maximum designing ability of the system
T= Ti*Pi / Pi ( Ti=|Tst_i the setting temperature - Tnh_i the indoor environment
temperature|; Pi i the ability of the indoor unit)
Cooling/dehumidification mode:
The percentage of the
rated frequency P
Heating mode
The percentage of the
rated frequency P
The indoor setting
airflow speed
The percentage of the
rated frequency Ki
K= (Ki*Pi)/ Pi
The calculation of the actual output frequency:
when there is no healthy airflow: F= F-ED-*(rated frequency) P K
When the healthy airflow has been set: F =F-ED-* P K airflow speed
Notes:
When cooling, it is needed to satisfy
F-MIN-d(compressor's Min_hz)< F<F-MAX-d(compressor's Max_hz)
When heating, it is needed to satisfy
F-MIN-r (compressor's Min_hz)< F<F-MAX-r (compressor's Max_hz)
