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=ě˄Ti*Pi˅/ěPi (Ti=|Tst_i-Tnh_i the indoor environment temperature| ;Pi˙i the ability of
the indoor unit)
Refrigeration/dehumidification:
Heating mode˖
K=ěKi/the number of running machines
The calculation of the actual output frequency: when there is no healthy airflow: F =F-ED-*hPhK
When the healthy airflow has been set: F =F-ED-*hPhK˄airflow speed˅hK˄healthy airflow˅
When refrigerating, it is needed to satisfy ˢˉ˩INˉ< F<ˢˉ˩˝˴ˉ
When heating, it is needed to satisfy ˢˉ˩INˉr< F<ˢˉ˩˝˴ˉr
5.2.2˖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).
5.2.2.1˖ The outdoor fan control when refrigerating or dehumidifying
After the compressor is started for 5 seconds, the outdoor fan is started at the medium speed at first,
after 30 seconds,it begins to control the airflow speed according to the temperature conditions of the
outdoor environment.
