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 actural 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=

Refrigeration/dehumidification:
The percentage of

Heating mode
T
The percentage of the
rated frequency P
K= Ki/the number of running machines
The indoor set
airflow speed
The percentage
of the
frequency Ki
The calculation of the actual output frequency: when there is no healthy airflow: F =F-ED-* P K
When the healthy airflow has been set: F =F-ED-* P K airflow speed
When refrigerating, it is needed to satisfy
When heating, it is needed to satisfy
7.1.2 The outdoor fan control (exchange fan)
When the fan is changed among every airflow speed (including stop blowing), in order to avoid
the airflow speed from skipping frequently, it must be kept under each mode for over 30 seconds,
and then it can be changed to another mode (when refrigerating, the time is changed to 15
seconds).
