The speeds of increasing or decreasing the frequency of the compressor
The speed of increasing or decreasing the frequency rapidly 1 -----------1HZ/second
The speed of increasing or decreasing the frequency slowly 2 -----------1HZ/10seconds

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
