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
Refrigeration/dehumidification mode:
The indoor setting
airflow speed
The percentage of the
rated frequency K
Heating mode:
●
The indoor setting
airflow speed
The percentage of the
rated frequency K
The calculation of the actual output frequency:
●
F= F-ED-*(rated frequency)×K
F -ED-*(rated frequency)= The frequency which is limited by the outdoor environment temperature
