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= Ti*Pi / Pi ( Ti=|Tst_i-Tnh_i the indoor environment temperature| ;Pi i the
ability of the indoor unit)
