The speed of increasing or decreasing the frequency rapidly 1 -----------1HZ/second
The speed of increasing or decreasing the frequency slowly 2 -----------1HZ/10seconds
5.2.1.4 The calculation of the compressor's frequency
1 The minimum/maximum frequency limitation
A While refrigerating:
IN
B While heating:
IN is the minimum operation frequency of the compressor.

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