Refrigeration/dehumidification mode::
Serial No. Temperature scope Frequency limitation
1 Wh_c<16 Max_hz1 37 HZ
2 Wh_c<23 Max_hz2 45 HZ
3 Wh_c<29 Max_hz3 56 HZ
4 Wh_c<32 Max_hz4 63 HZ
5 Wh_c<40 Max_hz5 90 HZ
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:

F（ reference frequency）=∑Fi（ reference frequency）
Note - valid internal machine (starting and running in accordance with the state) to participate
in the calculation
Fi（ reference frequency）＝Fei（Computed base frequency）*Kw
（Outer ring temperature coefficient（External ring temperature on frequency limitation
section））*Pi（Temperature difference between the weight） *Ki（Wind speed weight）
（Note: the reference frequency Fi is rounded after calculation and no rounding is performed；）
