1˅ǃThe minimum/maximum frequency limitation
AˊWhile refrigerating: ˢˉ˩˝˴ˉ is the maximum operation frequency of the compressor;
ˢˉ˩INˉ is the minimum operation frequency of the compressor.
BˊWhile heating: ˢˉ˩˝˴ˉ is the maximum operation frequency of the compressor; ˢˉ
˩INˉis the minimum operation frequency of the compressor.
1˅ǃThe frequency limitation which is affected by the environment temperature.

Remarks: the above are the maximum frequency limitations of the complete appliance which are
affected by the environment, and they have nothing to do with the ability of the indoor unit.

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)
